MASTER MINIMUM EQUIPMENT LIST PROCEDURES GUIDE

G. Notes. Notes provide additional information for crewmember or maintenance consideration. Notes are used to identify applicable material, which is intended to assist with compliance, but do not relieve the aircraft operator of the responsibility for compliance with all applicable requirements. Additional notes may be amended, deleted, or added to the MEL by the aircraft operator, as appropriate. Notes are not a part of the provisos. H. Vertical Bar (change bar). A vertical bar indicates a change, addition, or deletion in the adjacent text for the current revision of that page only. All change bars applicable to the previous revision of the MMEL are removed prior to the release of the next revision. 3. Airplane Flight Manual (AFM), Rotorcraft Flight Manual (RFM). The FAA-approved AFM/RFM is the document approved by the responsible FAA Aircraft Certification Office (ACO) during type certification. The approved flight manual for the specific aircraft is listed on the applicable Type Certificate Data Sheet (TCDS). The approved flight manual is the source document for operational limitations and performance parameters for an aircraft. The term “approved flight manual” can apply to either an AFM or an RFM. The FAA requires an approved flight manual for aircraft type certification. 4. As Required by 14 CFR. When the MMEL states, “As Required by 14 CFR,” the listed instrument or equipment item is subject to certain provisions (restrictive or permissive) expressed in the 14 CFR operating rules. The number of items required by 14 CFR must be operative. When the listed item is not required by 14 CFR, it may be inoperative for the time specified by repair category. The term “14 CFR” has replaced “FAR” as the current reference to Federal Regulations pertaining to aviation. However, many, if not most, MMELs still contain the acronym “FAR”; therefore, this acronym is acceptable and retained in PL-25 and this definition. 5. Code of Federal Regulations (CFR) and Federal Aviation Regulations (FAR). CFR, the current term, and FAR both refer to the applicable portions of the Federal Aviation Act and Code of Federal Regulations. 6. Considered Inoperative. The phrase, “Considered Inoperative”, as used in the provisos, means that an instrument and equipment item must be treated for dispatch, taxi and flight purposes as though it were inoperative. The item will not be used or operated until the original deferred item is repaired. Additional actions include: documenting the item on the dispatch release (if applicable), placarding, and complying with all remarks, exceptions, and related MMEL provisions, including any (M) and (O) procedures and observing the repair category. United States Department of the Interior Office of Aviation Services AIRCRAFT: BELL 206 REVISION: 1 DATE: 06-28-2017 PAGE NO: VI DEFINITIONS Rev. 21 7. Continuing Authorization – Single Extension. An aircraft operator who has the authorization to use an FAA-approved MEL may also have the authority to use a continuing authorization to approve a single (one-time) extension to the repair interval for category B or C items in accordance with Operations Specification D095. Continuing Authorization – Single Extension is not authorized for repair category A and D items. 8. Dash (-). Indicates a variable number (quantity) of the instrument and equipment items may be installed or required for dispatch. This is common when a fleet MEL is used since aircraft of the same make and model may have differing numbers of specific instrument and/or equipment items installed. 9. Day of Discovery. This is the calendar-day an equipment/instrument malfunction was recorded in the aircraft maintenance record/logbook. This day is excluded from the calendar-days or flight-days specified in the MMEL for the repair interval of an inoperative instrument and/or equipment item. This provision is applicable to all MMEL items; i.e., categories A, B, C, and D. 10. Deactivated and/or Secured. When the MMEL refers to an instrument and/or equipment item as deactivated and/or secured, the specified component must be put into an acceptable condition for safe flight. An acceptable method of deactivating and/or securing will be established by the aircraft operator. 11. Deleted. "Deleted" in the remarks column after a sequence item indicates that the item was previously listed but is now required to be operative if installed in the aircraft. 12. Extended Range Operations (ER). ER refers to extended range operations (ETOPS) of an airplane with operational approval to conduct ETOPS in accordance with the applicable regulations.\ 13. Excess Items. Excess items are those instrument and equipment items that have been installed that are redundant to the requirements of the 14 CFR. 14. Flight Day. A flight-day is a 24-hour period (from midnight to midnight) either universal coordinated time (UTC) or local time, as established by the aircraft operator, during which at least one flight is initiated for the affected aircraft. 15. Heavy Maintenance Visit (HMV). HMV is a scheduled C-check/D-check or airworthiness maintenance program inspection where the aircraft is scheduled to be out of service for 4 or more days. 16. Icing Conditions. An atmospheric environment that may cause ice to form on the aircraft (structural) or in the engine(s) (induction). 17. Inoperative. A system and/or component malfunction to the extent that it does not accomplish its intended purpose and/or is not consistently functioning normally within its approved operating limit(s) and/or tolerance(s). 18. Inoperative Components of an Inoperative System. Inoperative instrument and equipment items, which are components of a system that is inoperative, are usually considered components directly associated with and having no other function than to support that system (warning/caution systems associated with the inoperative system must be operative unless relief is specifically authorized per the MMEL). 19. Is Not Used. The phrase “Is Not Used” in the provisos, remarks or exceptions for an MMEL instrument or equipment item may specify that another item in the MMEL “is not used”. In such cases, crewmembers must not activate, actuate, or otherwise utilize that item under normal operations. It is not necessary for aircraft operators to accomplish the (M) procedure(s) associated with the item. However, operational requirements must be complied with, and an additional placard must be affixed, to the extent practical, adjacent to the control or indicator for the item that is not used. This informs crewmembers that an instrument or equipment item is not to be used under normal operations. 20. Nonessential Equipment and Furnishings (NEF). NEFs are those items installed on the aircraft as part of the original type certification (TC), STC, engineering order, or other form of alteration that have no effect on the safe operation of flight and would not be required by the applicable certification rules or operational rules. They are those items that, if inoperative, damaged, or missing, have no effect on the aircraft’s ability to be operated safely under all operational conditions. NEF items are not instrument and equipment items already identified in the MEL or CDL of the applicable aircraft. They do not include instrument and equipment items that are functionally required to meet the certification rule or for compliance with any operational rule. United States Department of the Interior Office of Aviation Services AIRCRAFT: BELL 206 REVISION: 1 DATE: 06-28-2017 PAGE NO: VII DEFINITIONS Rev. 21 21. Operative. An operative system and/or component will accomplish its intended purpose and is consistently functioning normally within its design operating limit(s) and tolerance(s). When an MMEL item specifies that an item of equipment must be operative, it does not mean that it’s operational status must be verified; it’s to be considered operative unless reported or known to be malfunctioning. When an MMEL item specifies that an item of equipment must be verified operative, it means that it must be checked and confirmed operative at the interval(s) specified for that MMEL item. When an MMEL item specifies that an item of equipment must be verified but no interval is specified, verification is required only at the time of deferral. Other terminology sometimes used interchangeably with “operative” within the MMEL is “operates normally”, "fully operative", and "considered operative”. The aircraft operator's MEL may incorporate standardized terminology of the aircraft operator’s choice to specify that an item of equipment must be operative, provided the aircraft operator's MEL definitions indicate that the selected "operative" terminology means that the required item of equipment will accomplish its intended purpose and is consistently functioning normally within its design operating limit(s) and tolerance(s). 22. Placarding. Each inoperative instrument or equipment item must be placarded to inform and remind the crewmembers and maintenance personnel of the item condition. To the extent practical, placards should be located adjacent to the control or indicator for the item affected; however, unless otherwise specified (i.e. AFM), placard wording and location will be determined by the aircraft operator. 23. Repair Category. All users of an MEL approved under parts 91K, 121, 125, 129, 135, and 142 must effect repairs of inoperative instrument and equipment items, deferred in accordance with the MEL, at or prior to the repair times established by the following letter designators. Part 91 MEL users (D095/D195 LOAs) are not required to comply with the repair categories, but will comply with any provisos defining a repair interval (flights, flight legs, cycles, hours, etc): A. Repair Category A. This category item must be repaired within the time interval specified in the “Remarks or Exceptions” column of the aircraft operator’s approved MEL. For time intervals specified in “calendar days” or “flight days”, the day the malfunction was recorded in the aircraft maintenance record/logbook is excluded. For all other time intervals (i.e., flights, flight legs, cycles, hors, etc.), repair tracking begins at the point when the malfunction is deferred in accordance with the operator’s approved MEL. B. Repair Category B. This category item must be repaired within 3 consecutive calendar-days (72 hours) excluding the day the malfunction was recorded in the aircraft maintenance record/logbook. For example, if it were recorded at 10 a.m. on January 26th, the 3-day interval would begin at midnight the 26th and end at midnight the 29th. C. Repair Category C. This category item must be repaired within 10 consecutive calendar-days (240 hours) excluding the day the malfunction was recorded in the aircraft maintenance record/logbook. For example, if it were recorded at 10 a.m. on January 26th, the 10-day interval would begin at midnight the 26th and end at midnight February 5th. D. Repair Category D. This category item must be repaired within 120 consecutive calendar-days (2880 hours) excluding the day the malfunction was recorded in the aircraft maintenance record/logbook. 24. Takeoff. Takeoff is the act of beginning a flight in which an aircraft is accelerated from a state of rest to that of flight. For the purposes of MEL relief, this translates to the point at which the pilot physically begins to apply power to initiate the takeoff from the runway or takeoff surface. 25. Triple Asterisk (***). Indicates an item which is not required by regulation but which may have been installed on some models of aircraft covered by this MMEL. This item may be included on the aircraft operator’s MEL after the approving office has determined that the item has been installed on one or more of the aircraft operator’s aircraft. The symbol, however, must not be carried forward into the aircraft operator’s MEL. It should be noted that neither this policy nor the use of this symbol provides authority to install or remove an item from an aircraft. 26. Visible Moisture. An atmospheric environment containing water, in any form, that can be seen in natural or artificial light; for example, clouds, fog, rain, sleet, hail, or snow. 27. Visual Flight Rules (VFR). VFR is as defined in 14 CFR Part 91. This precludes a pilot from filing an Instrument Flight Rules (IFR) flight plan. 28. Visual Meteorological Conditions (VMC). VMC means the atmospheric environment is such that would allow a flight to proceed under the visual flight rules applicable to the flight. This does not preclude operating under Instrument Flight Rules. United States Department of the Interior Office of Aviation Services AIRCRAFT: BELL 206 REVISION: 1 DATE: 06-28-2017 PAGE NO: VIII DEFINITIONS Rev. 21 29. (M). This symbol indicates a requirement for a specific maintenance procedure which must be accomplished prior to operation with the listed item inoperative. Normally, these procedures are accomplished by maintenance personnel; however, other personnel may be qualified and authorized to perform certain functions. Procedures requiring specialized knowledge or skill, or requiring the use of tools or test equipment, should be accomplished by maintenance personnel. The satisfactory accomplishment of all maintenance procedures, regardless of who performs them, is the responsibility of the aircraft operator. Appropriate procedures are required to be produced as part of the aircraft operator’s manual or MEL. 30. (O). This symbol indicates a requirement for a specific operations procedure which must be accomplished in planning for and/or operating with the listed item inoperative. Normally, these procedures are accomplished by the flightcrew; however, other personnel may be qualified and authorized to perform certain functions. The satisfactory accomplishment of all procedures, regardless of who performs them, is the responsibility of the aircraft operator. Appropriate procedures are required to be produced as a part of the aircraft operator’s manual or MEL. United States Department of the Interior Office of Aviation Services AIRCRAFT: BELL 206 REVISION: 1 DATE: 06-28-2017 PAGE NO: IX PREAMBLE PART 91, REV. 2 This preamble is applicable to, and will be included in, master minimum equipment lists (MMEL) issued under the provisions of Section 91.213(a)(2). It is not applicable to MMEL's issued under the provisions of Parts 121, 125, 129, and 135 of the FAR. Except as provided in Section 91.213(d), or under the provisions of an approved MMEL, all equipment installed on an aircraft in compliance with the airworthiness standards or operating rules must be operative. Experience has shown that with the various levels of redundancy designed into modern aircraft, operation of every system or component installed may not be necessary when the remaining equipment can provide an acceptable level of safety. An MMEL is developed by the FAA, with participation by the aviation industry, to improve aircraft utilization and thereby provide more convenient and economic air transportation for the public. The FAA-approved MMEL includes only those items of equipment which the Administrator finds may be inoperative and yet maintain an acceptable level of safety by appropriate conditions and limitations. The MMEL and FAA-issued letter of authorization are used as an MEL by an operator and permit operation of the aircraft with inoperative equipment. The MMEL includes all items of installed equipment that are permitted to be inoperative. Equipment required by the FAR, and optional equipment in excess of FAR requirements, is included with appropriate conditions and limitations. For each listed item, the installed equipment configuration considered to be normal for the aircraft is specified. Items of equipment installed on aircraft (except for passenger convenience items such as galley equipment and passenger entertainment devices), such as "TCAS," windshear detection devices, and ground proximity warning systems (GPWS) that are in excess of what is required, and are not listed on the MMEL, must be operational for dispatch unless MMEL relief is sought through the FSDO having jurisdiction for the operator. If MMEL relief is sought, the operator must notify the FSDO who will make a request of the FOEB to convene and consider adding the equipment to the MMEL. The operator may then dispatch with the equipment disabled, or rendered inoperative, in accordance with all FAR. It is incumbent on the operator to endeavor to determine if O and/or M procedures for that equipment must be developed. If so, any procedures developed must comply with all FAR. Procedures developed to use the MMEL must not conflict with either the aircraft flight manual limitations, emergency procedures, or with airworthiness directives (AD), all of which take precedence over the MMEL and those procedures. Suitable conditions and limitations in the form of placards, maintenance procedures, crew operating procedures, and other restrictions, as necessary, are required to be accomplished by the operator to ensure that an acceptable level of safety is maintained. Those procedures should be developed from guidance provided in the manufacturer's aircraft flight and/or maintenance manuals, manufacturer's recommendations, engineering specifications, and other appropriate sources. Procedures must not be contrary to any FAR. Wherever the statement "as required by FAR" appears in the MMEL, the operator must either list the specific FAR by part and section and carry the FAR on board the aircraft or specify the requirements and/or limitations to conduct the flight in accordance with the appropriate FAR. The MMEL is intended to permit operations with inoperative items of equipment for the minimum period of time necessary until repairs can be accomplished. It is important that repairs be accomplished at the earliest opportunity in order to return the aircraft to its design level of safety and reliability. Inoperative equipment in all cases must be repaired, or inspected and deferred, by qualified maintenance personnel at the next required inspection Section 91.405(c). The repair intervals indicated by the Letters A, B, and C inserted adjacent to column 2 are NOT applicable to this MMEL. The MMEL provides for release of the aircraft for flight with inoperative equipment. When an item of equipment is discovered to be inoperative, it is reported by making an entry in the aircraft maintenance records. The item is then either repaired or deferred per the MMEL or other approved means acceptable to the Administrator prior to further operation. In addition to the specific MMEL conditions and limitations, determination by the operator that the aircraft is in condition for safe operations under anticipated flight conditions must be made for all items of inoperative equipment. When these requirements are met, the aircraft may be considered airworthy and returned to service. Operators are responsible for exercising the necessary operational control to ensure that an acceptable level of safety is maintained. When operating with multiple inoperative items, the interrelationship between those items, and the effect on aircraft operation and crew workload, must be considered. Operators are expected to establish a controlled and sound repair program, including the parts, personnel, facilities, procedures, and schedules to ensure timely repair. WHEN USING THE MMEL, COMPLIANCE WITH THE STATED INTENT OF THE PREAMBLE, DEFINITIONS, CONDITIONS, AND LIMITATIONS SPECIFIED IN THE MMEL IS REQUIRED. United States Department of the Interior Office of Aviation Services AIRCRAFT: BELL 206 REVISION: 1 DATE: 06-28-2017 PAGE NO: X PROCEDURES 1.1 Purpose. This master minimum equipment list (MMEL) procedures guide is intended to facilitate safe and efficient utilization of fleet, government owned and operated, aircraft. Inoperative equipment must be repaired, replaced or removed at the earliest opportunity. The repair intervals indicated by the Letters A, B, and C inserted adjacent to column 2 are NOT applicable to this MMEL Procedures Guide. In any case all deferred equipment must be addressed at the next scheduled inspection, i.e. 100 hour or annual inspection. 1.2. Policy See DOI 351 DM 2.4A(3) 2.2 Procedure When a discrepancy is identified, it should be brought to the attention of your OAS Fleet Manager (FM) as soon as possible. The FM can arrange for a suitable maintenance facility to begin work and coordinate contract actions with the contracting officer. Remember, if the repair is going to cost more $2500, a contracting officer will need to approve obligating the funds. The sooner the OAS FM is brought into the process, the sooner the aircraft will be back in the air. Discrepancies can be placed in one of two categories. The first is a grounding discrepancy that compromises the airworthiness of the aircraft (e.g., a cracked spar). A grounding discrepancy is written up on the OAS-2 form and must be corrected and signed off by an authorized mechanic before the aircraft is released for flight. A grounding discrepancy can be dealt with one of two ways; it can be repaired or deferred IAW 14 CFR 91. A grounding discrepancy for inoperative equipment can be deferred if the specific piece of equipment is not required for flight. The Master Minimum Equipment List (MMEL) and this Procedures Guide must be used to determine if the aircraft can be flown with the item inoperative. The following steps must be taken by the pilot or maintenance person to secure the item before flight. If the inoperative equipment is not listed in the MMEL, it is required for flight. The second type of discrepancy is one that does not affect airworthiness, but is something we will want to correct eventually (e.g., a tear in the upholstery). This type of discrepancy is written up as an “info write up” on the OAS-2. Send the white copy of the form to your OAS Fleet Manager so he can begin planning for the best time and place to correct the discrepancy. Info write-ups do not require a documented corrective action before flight. United States Department of the Interior Office of Aviation Services AIRCRAFT: BELL 206 REVISION: 1 DATE: 06-28-2017 PAGE NO: XI PROCEDURES Procedure for correcting discrepancies: Discrepancy Identified: NOTE: When equipment fails and becomes inoperative in-flight follow the manufactures’ procedures to the termination of the flight. 1) Contact your OAS Fleet Manager, Brian Green, Brian_Green@ios.doi.gov, 208-433-5082 (Alternate, Walker Craig, walker_craig@ios.doi.gov, 208-433-5077) 2) Is the airworthiness of the aircraft affected? The pilot and FM (a certificated mechanic) must make this determination together. a) Does the INOP equipment constitute a hazard to the aircraft? i) Yes, go to 5 ii) No, continue b) Is the INOP equipment required by an AD? i) Yes, grounded go to 5 ii) No, continue c) Is the equipment non-essential equipment or cosmetic in nature? i) Yes, go to 6 ii) No, continue 3) Is the INOP equipment listed in the MMEL? i) Yes, go to 4 ii) No, Aircraft is grounded. Go to 5 4) Deferral procedure a) Look at the aircraft to determine how many are installed and then look in column 3 determine how many are required. i) If the number required is more than the number installed and operative the item cannot be deferred. The aircraft is grounded go to 5. ii) If the number required is less than the number installed and operative, continue. b) Read column 4 Remarks and Exceptions. All instructions must be complied with. i) (O) or (M) indicates a required procedure. (O)&(M) procedures are detailed in this document hereafter. (O) Procedures can be accomplished by the pilot. (M) Procedures must be accomplished by a qualified aircraft mechanic. ii) “As required by 14 CFR” indicates it may be deferred under certain circumstances as dictated by regulation. See details listed in this document hereafter. iii) Placard inoperative equipment. 1. Place the placard as close to the inoperative piece of equipment as possible or control in the cockpit as appropriate. 2. The placard needs to be in a conspicuous location to alert all pilots that there is inoperative equipment. 3. Put the date the item was deferred on the placard. United States Department of the Interior Office of Aviation Services AIRCRAFT: BELL 206 REVISION: 1 DATE: 06-28-2017 PAGE NO: XII PROCEDURES iv) Complete OAS-2 1. In the Discrepancies area write the description of the inoperative equipment as found in the MMEL. 2. In the Corrective Action area write, “Deferred IAW MEL item # ____.” 3. In the Corrective Action area include the expiration date if required. 4. In the Signature area sign and write you’re A&P certificate number or pilot certificate number as appropriate. 5. Enter the deferred equipment into the Deferred Aircraft Discrepancy Log, include expiration date if required, found on the flap in the OAS-2. v) When operating with multiple inoperative items, the interrelationship between those items, and the effect on aircraft operation and crew workload, must be considered. vi) Prior to each flight the pilot should review the OAS-2, Log of Aircraft Discrepancies Log to verify the flight can be accomplished safely and legally. vii) Go fly! NOTE: When an inoperative item is deferred for one flight the next flight might not necessarily be safe or legal with the same item deferred. 5) Coordinate with OAS FM and maintenance facility to get the aircraft repaired. Ensure the repair is documented in the aircraft log books (if they are locally available) and on the OAS-2. Ensure an authorized mechanic signs the corrective action block, including his certificate number. Coordinate the flight release with the OAS FM, send the white copy of the OAS-2 to the OAS FM. Go fly! 6) For information write-ups, document the discrepancy as “informational only” on the OAS-2 in the “Discrepancies” block. a) Send the white copy of OAS-2 to the OAS FM. b) OAS FM will determine what and when action is required. c) If the OAS FM determines the discrepancy is an airworthiness issue, go to 2. d) If the OAS FM determines the discrepancy is not an airworthiness issue then: i) The OAS FM will coordinate with the pilot and repair facility to get the discrepancy repaired. ii) The repair facility will document the corrective action on the OAS-2 as coordinated with the OAS FM.

III HIGHLIGHTS OF CHANGE This Master Minimum Equipment List (MMEL) has been reformatted in compliance with the Federal Aviation Administration, Joint Aircraft System/Component (JASC) Code Table, and Definitions are available for download or viewing at: (http://av-info.faa.gov/sdrx/references.aspx). This replaces the former Airline Transport Association (ATA) coding used in previous documents. JASC Coding is a four-digit number format and as the title suggests, it contains a System Code and a Component Code. The first two digits are the System Code, which is similar to ATA Coding for their first two numbers. The last two digits in the JASC Code are the Component Code, which defines the specific component. The item number is a sequential number given for additional Components with the same JASC Code. For Example: JASC Code 2410, where Code 24 represents the “Electrical Power” system, and Component Code 10, represents the “Alternator-Generator Drive” system. PAGE NO.
