PERIODIC INSPECTIONS (cont)
NOTES:
1. Refer to the last card of the Piper Parts Price List - Aerofiche, for a check list of current revision dates
to Piper inspection reports and manuals.
2. All inspections or operations are required at each of the inspection intervals as indicated 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. Inspections given for the power plant are based on the engine manufacturer's operator's manual
(Lycoming Part No. 60297-10) for this airplane. Any changes issued to the engine manufacturer's
operator's manual shall supersede or supplement the inspections outlined in this report.
6. Intervals between oil changes can be increased as much as 100% on engines equipped with full flow
(cartridge type) oil filters, provided the element is replaced each 50 hours of operation.
7. Replace or overhaul as required or at engine overhaul. (For engine overhaul, refer to latest revision
Lycoming Service Letter L201.)
8. Replace flexible oil lines at engine TBO per latest revision Lycoming Service Bulletin 240.
9. The compressor oil level should not be checked unless a Freon leak has occurred, requiring an
addition of Freon to the system.
10. Clean any traces of oil from the clutch surface.
11. 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 SSP-1776.
12. 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 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 conditions, the cylinder should be replaced.
13. Check throttle body attaching screws for tightness; the correct torque for these screws is 40 to 50
inch-pounds.
14. Replace flexible fuel supply hose and interconnect hose couplings at time of engine overhaul.
15. Replace fuel tank vent line flexible connections as required, but no later than 1000 hours of service.
