Seller’s sole obligation under this warranty is limited to replacement or repair of parts which are determined to Seller’s reasonable satisfaction to have been defective with 1,000 hours of operation or one (1) year after installation, whichever occurs first and reimbursement of reasonable freight charges. After 200 hours of use, there will be a prorated charge to the Purchaser for replacement parts (prorating the hours of total use against the then applicable part life or 2,000 hours, whichever is the lesser). Defective parts must be reported in writing to the Seller’s Warranty Administration within 90 days of being found defective. Replacement of parts may be with either new or reconditioned parts, at Seller’s election. Warranty adjustment is contingent upon the Purchaser complying with the Warranty Remedies as described in the Commercial Warranty Information brochure and the Seller’s Warranty Administration disposition instructions for defective parts. Failure to comply with all of the terms of this paragraph may, at Seller’s sole option, void this warranty.

GENERAL This chapter contains the requirements for the Scheduled, Special, and Conditional Inspections and a Component Overhaul Schedule. WARNING FAILURE TO CORRECT CONDITIONS S U C H A S , B U T N O T L I M I T E D T O , CORROSION, EROSION, MECHANICAL DAMAGE, OR OBVIOUS WEAR FOUND DURING A SCHEDULED INSPECTION C O U L D S E R I O U S LY A F F E C T T H E AIRWORTHINESS OF THE HELICOPTER. These inspection requirements constitute an approved inspection program for the Bell Helicopter Model 212. For the convenience of the operator, two separate Scheduled Inspections are provided as follows: Part A scheduled inspections consists of a daily inspection, 100 hour/12 calendar month inspection, 1000 hour inspection, and a 3000 hour/5 year inspection. Part B scheduled inspections consists of a 25 hour/ 30 day inspection, 300 hour inspection, 600 hour/ 12 month inspection, and a 3000 hour/5 year inspection. Either Part A or Part B inspection program may be utilized. However, once a helicopter has been started on an inspection program, it shall be maintained on that program except as follows: • If a helicopter is being inspected on the Part A inspection program and it is preferable to change to the Part B program, a complete Part A — 1000 Hour Inspection shall be accomplished. The helicopter may then be changed to the Part B inspection program beginning with a 25 Hour/15 Day Inspection. • If a helicopter is being inspected on the Part B inspection program and it is preferable to change to the Part A program, a complete Part B — 600 Hour/12 Month Inspection shall be accomplished. The helicopter may then be changed to the Part A inspection program beginning with a Daily Inspection. The inspection intervals given in this chapter are the maximum permitted. Do not exceed these intervals. The owner/operator is responsible for increasing the scope and the frequency of the inspections as necessary. Make sure the helicopter is maintained safely during all unusual local changes, such as environmental conditions, helicopter use, etc. You can request changes to the requirements in this chapter through the local Aviation Authority. The inspection intervals and the component overhaul schedule provided in this chapter are applicable only to Bell Helicopter Textron approved parts. NOTE The time period given for the overhaul of a component (or the failure to give a time period for the overhaul of a component) does not constitute a warranty of any kind. The only warranty applicable to the helicopter or any component is the warranty included in the Purchase Agreement for the helicopter or the component. The Time Between Overhaul (TBO) and the inspection periods are determined through experience, tests, Lead The Fleet (LTF), or any other special programs and the judgement of Bell Helicopter Textron engineers. They are subject to change only by Bell Helicopter Textron or an approved Airworthiness Authority. Changes to the TBO will be introduced by either revision to this chapter or a Technical Bulletin. Every calendar and hourly inspection is a thorough visual inspection to determine the airworthiness of the helicopter and the components. Qualified persons must do the inspections in accordance with quality standard aircraft practices and the applicable maintenance manuals. Bell Helicopter Textron considers that it is mandatory to obey all the applicable Alert Service Bulletins (ASB) and the Airworthiness Directives (AD). BHT-212-MM-1 5-00-00 Page 6 Rev. 14 26 JUN 2013 Export Classification C, ECCN EAR99 Component operating time records are necessary for components that have scheduled maintenance procedures, which are different from those of the airframe. It is the owner/operator’s responsibility to keep the Historical Service Records (HSR) for the applicable component and to do the necessary maintenance procedures. Before each inspection, remove or open the necessary cowlings, fairing, inspection doors, and panels. 5-2. INSPECTION REQUIREMENTS This manual does not include specific inspections required by the FAA or other government regulatory authorities. These specific inspections are given by your government regulatory authority. Refer to their requirements for these specific inspections. The owner/operator of the helicopter is responsible for the maintenance done on the helicopter. It is the owner.operator’s responsibility to: 1. Establish, maintain, and review the log books for discrepancies. 2. Make sure the Alert Service Bulletins (ASB), the Airworthiness Directives (AD), and the special inspections are done when they are required to be done. 3. Make sure the scheduled inspections, the special inspections, and the required tests for all of the installed kits are complied with. 4. Make sure all parts and components for which Historical Service Records are required have documented traceability to their original installation in the helicopter. WARNING A L L PA R T S R E M O V E D , D U E T O R E A C H I N G T H E I R L I M I T S O R A S A RESULT OF AN ACCIDENT/INCIDENT I N S P E C T I O N A N D D E E M E D U N A I R W O R T H Y, S H A L L B E PERMANENTLY MARKED AS SCRAP OR P H Y S I C A L LY D E S T R O Y E D TO T H E EXTENT THAT THERE IS NO CHANCE OF REPAIR OR INSTALLATION ON ANY HELICOPTER OR COMPONENT. 5. Make sure all limited life parts that have completed their published operating limits are replaced. 6. Make sure all of the components that have completed their published overhaul periods are overhauled. 7. Make sure all of the maintenance that is done on the helicopter is done by an approved maintenance organization. The maintenance organization/person doing the maintenance is responsible for the quality of the maintenance done. The owner/operator may choose to ask the maintenance organization/person doing the maintenance to perform the tasks listed by prior arrangement through a separate formal agreement. 5-3. CRASH DAMAGE Because of the many possible combinations that can result from crash damage, it is not possible to include the specific repair tasks in this category. The helicopter mechanic must make an analysis of the crash damage for each situation. Do the repair in accordance with the degree of damage to the specific part and the applicable repair procedures in this manual. Call Product Support Engineering with your analysis of the crash damage. 5-4. TYPES OF INSPECTIONS 1. The maintenance procedures may include scheduled inspections, special inspections, conditional inspections, component interim inspections, and component overhaul inspections. a. Scheduled inspections must occur at specified operating intervals. The intervals may be in operating time (hours), cycles, torque events (RIN), calendar (days, months, years) or other assigned units. This makes sure that the helicopter is airworthy. • Scheduled inspections — Part A consists of: BHT-212-MM-1 5-00-00 26 JUN 2013 Rev. 14 Page 7 Export Classification C, ECCN EAR99 – Daily inspection — Accomplish daily before flight operation. – 100 hours/12 calendar months — Accomplish each 100 hours of flight operation or 12 calendar months, whichever comes first. – 1000 hours — Accomplish each 1000 hours of flight operation. – 3000 hours/5 years — Accomplish each 3000 hours of flight operation or each 60 calendar months, whichever comes first. • Scheduled inspections — Part B consists of the following: – 25 hours/30 days — Accomplish each 25 hours of flight operation or each 30 days, whichever comes first. – 300 hours — Accomplish each 300 hours of flight operation. – 600 hours/12 months — Accomplish each 600 hours of flight operation or each 12 calendar months, whichever comes first. – 3000 hours/5 years — Accomplish each 3000 hours of flight operation or each 60 calendar months, whichever comes first. b. Special inspections are of a temporary nature or of a special interval that is not consistent with the scheduled inspections. c. Conditional inspections do not occur at a specified time. A conditional inspection is the result of known or suspected unusual event, known or suspected malfunctions, or defects. d. An interim inspection occurs between overhauls. e. The component overhaul schedule gives the elapsed operating time at which a component must be removed, disassembled, examined for condition, and overhauled, in accordance with data approved by Bell Helicopter Textron. 2. Airworthiness limitations — Replace components in accordance with Airworthiness Limitations Schedule (Chapter 4). 3. Lubrication and servicing requirements are in addition to those stated in this chapter (Chapter 12). 4. For corrosion control refer to the Corrosion Control Guide, CSSD-PSE-87-001 and the BHT-ALL-SPM. 5. For the PT6T-3/-3B engines, refer to the Pratt & Whitney Canada Maintenance Manual for the scheduled inspection, special inspection, conditional inspection, and component overhaul schedule. 6. For the common Bell Helicopter Textron approved optional equipment that is integrated into this maintenance manual, refer to this chapter for the scheduled inspection, conditional inspection, component interim inspection, and component overhaul inspection. 7. For all other Bell Helicopter Textron approved equipment, refer to the applicable Service Instruction for the scheduled inspection, special inspection, conditional inspection, component interim inspection, and component overhaul inspection. 8. For the inspection requirements for optional equipment approved under Supplement Type Certificate (STC), refer to the applicable STC documentation. Maintenance and inspection of these items are the responsibility of the owner/operator. 5-5. DEFINITIONS • Inspect, check, examine — Determine condition relative to an established standard. • Condition — The state of being of an item as related to serviceable or unserviceable standard. • Security — The presence of attaching parts that are properly tightened or appear to be, and the presence of properly installed (as required) locking devices such as lockwire, cotter pins, or other. • Standard — An established rule or measure to determine condition. • Damage — Physical deterioration whereby the standard renders the condition or an item acceptable or not acceptable for continuous use. BHT-212-MM-1 5-00-00 Page 8 Rev. 14 26 JUN 2013 Export Classification C, ECCN EAR99 • Discard — Reject a component that has damage that cannot be repaired. To permanently remove from service. • Preventive maintenance — Simple or minor preservation and the replacement of small standard parts not involving complex assembly operations. • Maintenance — Inspection, overhaul, repair, preservation, and the replacement of parts, but excludes preventive maintenance. • Operating time — Time required to be recorded in historical record sheets or helicopter logs. Operating time to be recorded may be identified as follows: – Time in service — Time from the moment a helicopter leaves the surface of the earth until it touches down at the next point of landing. Time during which the engine and rotor are turning with the helicopter on the ground is not taken into account. – Calendar time — Elapse time starts the day the inspection is accomplished, the component is installed, or the rotor is turned for the first time and ends on the last day of the month that the time limit expires. Calendar time shall be recorded without interruption. Removal of the component or storage of the helicopter etc. does not stop calendar time. • Planned event — Occurrence of interval in which a specific action is to be taken as in the case of preventive maintenance, scheduled overhaul, or replacement in accordance with maximum airworthiness life guidelines. • Lead The Fleet (LTF) Program — This is a program to validate the performance of an approved product improvement or a change to a maintenance interval. The engineering aspects of this change are approved. The program is closely monitored by Bell Helicopter Textron in an operational environment with selected operators. • Special Programs — These are approved programs that may be initiated under certain special conditions to meet specific requirements. These programs will be clearly defined through a plan and the engineering and maintenance aspects will be approved by the regulatory authorities. 5-6. INSPECTION AND OVERHAUL TOLERANCE WARNING DO NOT APPLY THESE TOLERANCES T O PA R T S W I T H A L I M I T E D AIRWORTHINESS LIFE (CHAPTER 4). The Bell Helicopter Textron approved tolerance for scheduled inspections, special inspections, interim inspections, and overhaul intervals, unless otherwise stated, is 10% or up to a maximum of 100 hours operating time/30 days calendar time, whichever is less. The tolerances are established for maintenance scheduling convenience only. Scheduled inspections, special inspections, interim inspections, or overhaul intervals required beyond the stated tolerances must be approved by Product Support Engineering. NOTE The following is only applicable for those operators whose governing aviation authority requires to specifically approve the inspection and overhaul tolerance. If approval of the inspection and overhaul tolerance is required by the applicable governing aviation authority, this is the responsibility of the owner/operator. Refer to the Pratt & Whitney Canada PT6T-3/-3B Maintenance Manual for inspection and overhaul tolerances.
