Description WARNING: FAILURE TO CONSULT APPLICABLE VENDOR PUBLICATION(S), WHEN SERVICING OR INSPECTING VENDOR EQUIPMENT INSTALLED IN PIPER AIRCRAFT, MAY RENDER THE AIRCRAFT UNAIRWORTHY. (SEE SERVICE MANUAL - INTRODUCTION - SUPPLEMENTARY PUBLICATIONS.) The recurring maintenance schedule for the PA-28-140/150/160/180/235 Cherokee airplanes is provided herein as a 50 Hour Progressive Inspection Program. Successful compliance with this inspection program requires reference to the latest revision of the PA-28-140/150/160/180/235 and PA-28R-180/200 Cherokee Service Manual (i.e., the Instructions for Continued Airworthiness (ICA)) available from your Piper Distributor as P/N 753-586. References to section (i.e., Section III) throughout this inspection manual are to the corresponding entries in the service manual. Piper Progressive Inspection Programs comply with the FAA Federal Aviation Regulations Parts 43, 91 and 135. The owner/operator is primarily responsible for maintaining the airplane in an airworthy condition, including compliance with all applicable Airworthiness Directives and conformity with the requirements in FAR 91.409, 91.411 and 91.413. The first overhaul or replacement of components should be performed at the given periods. The condition of various components can then be used as criteria for determining subsequent periods applicable to the individual airplane, depending on usage, providing the owner/operator has an established Part 91 Progressive Inspection Program (see 91.409(d)) or Part 135 Approved Aircraft Inspection Program (see 135.419). The time periods given for inspections of various components are based on average usage and environmental conditions. NOTE: The listed inspection, overhaul and replacement schedules do not guarantee that a particular item or component will reach the listed time without malfunction. Unique operating conditions encountered by individual airplanes cannot be controlled by the manufacturer. 2. Definitions A. Inspections - Must be performed only by Certified Mechanics who are qualified on this aircraft, using acceptable methods, techniques and practices to determine physical condition and detect defects. (1) Routine Inspection - Consists of a visual examination or check of the aircraft and its components and systems without disassembly. (2) Detailed Inspection - Consists of a thorough examination of the appliances, the aircraft and the components and systems with such disassembly as is necessary to determine condition. (3) Special Inspection - Involves those components, systems or structure which by their application or intended use require an inspection peculiar to, more extensive in scope or at a time period other than that which is normally accomplished during the event inspection. B. Checks - Can be performed by pilots and/or mechanics who are qualified on this aircraft and consist of examinations in the form of comparisons with stated standards for the purpose of verifying condition, accuracy and tolerances. C. Approved Inspection - Means a continuing airworthiness inspection of an airplane and its various components and systems, at scheduled intervals, in accordance with procedures approved by the FAA under FAR Part 91.409(d) or Part 135.419. PIPER AIRCRAFT CORPORATION PA-28-140/150/160/180/235, CHEROKEE SERIES 50 HOUR PROGRESSIVE INSPECTION MANUAL 16 Jan 31/08 D. Tests - Operation of aircraft components, appliances or systems to evaluate functional performance. (1) Operational Test - A task to determine that an item is fulfilling its intended purpose. The task does not require quantitative tolerances. This is a fault finding task. (2) Functional Test - A quantitative check to determine if one or more functions of an item performs within specified limits. This test may require the use of supplemental bench test equipment. (3) In addition, each of the above tests must be performed by an FAA Certified Repair Station with appropriate ratings or by a Certified Mechanic who is qualified on this aircraft. The recording of the above function must be made in the permanent aircraft records by the authorized individual performing the test. E. Bench Test - Means removal of component from the aircraft to inspect for cleanliness, impending failure, need for lubrication, repair or replacement of parts and calibration to at least the manufacturers specifications using the manufacturers recommended test equipment or standards or the equivalent. Each bench test will be performed by a Piper Service Center, FAA Certified Repair Station with appropriate rating or by a certified mechanic. This test will be performed at the scheduled interval regardless of any bench test performed on a particular component while being repaired/overhauled before scheduled interval bench test. After the component is installed into the aircraft, an operational test of the component and its related system should be performed to ensure proper function. Serviceable parts that were issued to the component will be filed in the aircraft permanent records. The person performing the test must make appropriate entries in the aircraft’s permanent maintenance record. F. Maintenance - The word maintenance, as defined by FAR Part 1, means “inspection, overhaul, repair, preservation and the replacement of parts, but excludes preventive maintenance.” G. On Condition Maintenance - A primary maintenance process having repetitive inspections or tests to determine the condition of units, systems, or portions of structure with regard to continued serviceability (corrective action is taken when required by item condition.) H. Time - as used in this manual. (1) Time-in-service for aircraft components, unless otherwise specified, is a cumulative total of flight hours or calendar time calculated from the time a new or overhauled component was first installed in any aircraft, and including: (a) the aircraft time that elapses from the initial installation to the first removal, if any; and, (b) the aircraft time that elapses from each subsequent installation to each subsequent removal, if any; or, (c) the calendar time elapsed since the installation. NOTE: Dates stamped on individual components at the time of manufacture are typically applied to determine shelf life - i.e. the maximum time allowed from manufacture/ assembly/cure until actually installed in an aircraft and are not relevant. Do not, however; ignore markings applied to life-limited parts when removed with time and/or cycles remaining on them. (2) Aircraft time, flight hours, or aircraft hours are the “Hobbs Time” shown on, or calculated from, the installed “Hour Meter.” PIPER AIRCRAFT CORPORATION PA-28-140/150/160/180/235, CHEROKEE SERIES 50 HOUR PROGRESSIVE INSPECTION MANUAL Jan 31/08 17 3.

Progressive Inspection Procedure The progressive inspection program cycle consists of four (4) 50 Hour Events, which provides for a complete aircraft inspection in 200 aircraft flying hours. The complete inspection cycle, Events (1), (2), (3) and (4), must be completed within twelve (12) calendar months. Each Event Inspection consists of a predetermined number of location inspections, both routine and detailed, as indicated below. The Event Inspections are conducted each 50 hours and must be done in sequence. Each Event Inspection will be conducted using an Event Inspection Work Sheet and, when completed, recorded in the Event Inspection Record. Late compliance with the Event Inspection Interval of 50 hours may be extended by not more than five (5) flying hours (10% of Event Inspection Interval). The excess time, however, must be deducted from the next 50 flying hours. Early compliance can be accomplished at the owner/operator’s discretion for convenience of scheduling. However, where early compliance is accomplished, the 50 flying hour interval for the next event inspection will be maintained. The Event Inspections are arranged so that the 200 flying hour cycle results in a complete inspection. When the Four Events are complete and recorded, an entry is made in the Progressive Inspection Cycle Record and Sign-off Sheet which is the running log or current status of the aircraft’s inspections. A. Overview (1) Four (4) Event Inspections at 50 Hour Intervals.

PIPER AIRCRAFT CORPORATION PA-28-140/150/160/180/235, CHEROKEE SERIES 50 HOUR PROGRESSIVE INSPECTION MANUAL 56 Jan 31/08 NOTES (Sheet 2 of 4) 10. Check cylinders for evidence of excessive heat indicated by burned paint on the cylinders. This condition is indicative of internal damage to the cylinder and, if found, its cause must be determined and corrected before the airplane is returned to service. Heavy discoloration and appearance of seepage at the cylinder head and barrel attachment area is usually due to emission of thread lubricant used during assembly of the barrel at the factory, or by slight gas leakage which stops after the cylinder has been in service for a while. This condition is neither harmful nor detrimental to engine performance and operation. If it can be proven that leakage exceeds these conditions, the cylinder must be replaced. 11. Not used. CAUTION: ENVIRONMENTAL REGULATIONS MAY REQUIRE SPECIAL EQUIPMENT AND PROCEDURES BE USED WHEN CHARGING AIR CONDITIONING SYSTEMS. 12. The compressor oil level should not be checked unless a refrigerant leak has occurred or system pressure has been released, requiring an addition of refrigerant to the system. 13.
