Must be performed only by licensed mechanics who are qualified on this aircraft; using acceptable methods, techniques, and practices to determine physical condition and detect defects. Inspections consist of a thorough examination of the aircraft, appliance, component, or system; with disassembly as necessary to determine condition. 2. Check. Can be performed by pilots and/or mechanics who are qualified on this aircraft. A check consists of an examination to compare and verify condition, accuracy and/or tolerances with stated standards. 3. Operational Test. Ascertains that a system or component is in operable condition and can be performed with the equipment installed in the aircraft. Each operational test must be performed by an FAA certificated repair station appropriately rated or by a licensed mechanic who is qualified on this aircraft. A record of this test must be made in the airplane’s permanent records by the authorized person performing the test. 4. Functional Test. Ascertains that a system or component is functioning properly in all aspects in conformance with minimum acceptable design specifications. This test may require the use of supplemental bench test equipment. Each functional test must be performed by an FAA certificated repair station appropriately rated or by a licensed mechanic qualified on this aircraft. A record of this test must be made in the airplane’s permanent records by the authorized person performing the test. Signature of Mechanic or Inspector: Certificate No.: Date: Total Time on Airplane: PA-30/39 TWIN COMANCHE (PART NUMBER 230–209) OCTOBER 1, 1998 — 4 — NOTES: 1. Refer to Piper's Customer Service Information Catalog No. 1753-755 (Aerofiche) for a checklist of current revision dates to Piper Inspection Reports and Manuals. References to Chapter or Section refer to the applicable Chapter/Section in the Twin Comanche Service Manual, P/N 753-645. 2. All inspections or operations are required at each of the inspection intervals as marked by a (O). Both the annual and 100 hour inspections are complete inspections of the airplane, identical in scope, while both the 500 and 1000 hour inspections are extensions of the annual or 100 hour inspection, which require a more detailed examination of the airplane, and overhaul or replacement of some major components. Inspections must be accomplished by persons authorized by the FAA. 3. Piper Service Bulletins are of special importance and Piper considers compliance mandatory. 4. Piper Service Letters are product improvements and service hints pertaining to servicing the airplane and should be given careful attention. 5. Refer to latest revisions of Lycoming Service Bulletin No. 480 and Lycoming Service Instruction No. 1014. Lycoming recommends the following oil change intervals: (a) For engines relying upon pressure screen filtration alone, change the oil and clean the pressure and suction screens each 25 hours of engine operation or every four months, whichever comes first: (b) For engines equipped with full-flow (cartridge) oil filters, change the oil and filter each 50 hours of engine operation or every four months, whichever comes first. Should fuel other than the specified octane rating for the power plant be used, refer to Lycoming Service Letter No. L185A for additional information and recommended service procedures. 6. Replace or overhaul as required or at engine overhaul. (For engine overhaul, refer to the latest revision of Lycoming Service Instruction No. 1009.) 7. Replace flexible oil, fuel and hydraulic lines in the engine compartment after 8 years, 1000 hours time-in-service, or at engine overhaul, whichever comes first. Pressure check fluid hoses in the fuselage and wing areas to system pressures after 10 years time-in-service. Visually check for leaks. Hoses in the fuselage and wing areas that pass the pressure check may remain in service and must be checked again after the next 5 years time-in-service. 8. Inspections given for power plant are based on the engine manufacturer’s operator’s manual. Any changes issued to the engine manufacturer’s operator’s manual shall supersede or supplement the instructions outlined in this report. Occasionally, service bulletins or service instructions are issued by Lycoming that require inspection procedures that are not listed in this manual. Such publications usually are limited to specific models and become obsolete after corrective steps have been accomplished. All such publications are available from Lycoming distributors, or from the factory by subscription. Consult the latest revision of Lycoming Service Letter No. L114 for subscription information. Maintenance facilities should have an up-to-date file of these publications available at all times. 9. Check cylinders for evidence of excessive heat which is 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 aircraft 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 awhile. This condition is neither harmful nor detrimental to engine performance and operation. If it can be proven that leakage exceeds these condition, the cylinder should be replaced. 10. At every 400 hours of engine operation, remove the rocker box covers and check for freedom of valve rockers when valves are closed. Look for evidence of abnormal wear or broken parts in the area of the valve tips, valve keeper, springs and spring seat. If any indications are found, the cylinder and all of its components should be removed (including the piston and connecting rod assembly) and inspected for further damage. Replace any parts that do not conform with limits shown in the latest revision for Lycoming Service Table of Limits No. SSP1776. 11. Refer to the latest revision of Piper Service Letter No. 782 for proper inspection and wear limits. 12. Replace all engine support bushings every 500 hours. 13. Replace rubber assist cords every 500 hours or every three years, which ever occurs first. 14. Refer to the latest revision of Piper Service Letter No. 851. 15. Refer to A.D. 81-19-04 and to the latest revision of Rayjay Service Letter No. 28. 16. Refer to Flight Manual Supplement for preflight and flight check, for intended function in all modes. 17. Examine cables for broken strands by wiping the cable with a cloth along the entire length of the cable. Visually inspect the cable thoroughly for damage not detected by the cloth. Replace damaged or frayed cables. Refer to Appendix I, Grid 1K1, and the latest edition of FAA Advisory Circular 43.13-1A, Paragraph 198. 18. Verify compliance with latest revision of Piper Service Bulletin No. 980. Inspect seat belt and shoulder harness ends and attachment points for condition and security. Inspect harness web material for condition and wear over its entire length. Particularly look for wear and fraying where harness web passes in and out of adjustable buckle end and shoulder harness inertial reel. If excessively worn, replace. On lap belts, inspect shoulder harness keeper nylon bushing. If excessively worn or missing, replacement of that half of the lap belt is required. 19. Verify compliance with latest revision of Piper Service Bulletin No. 836. 20. For aircraft in normal operation, each 7 years; or, for aircraft in training operations, each 2000 hours time-in-service: remove interior panels and headliner and conduct detailed inspection of aircraft structure (skin, bulkheads, stringers, etc.) for condition and security. Inspection of structure concealed by headliner may be accomplished by alternate means (i.e. - through the use of a borescope) without removing the headliner, providing access is obtained to all concealed areas and borescope provides sufficient detail to adequately accomplish the inspection.
