PIPER CHEROKEE WARRIOR SERVICE MANUAL
NOTES:
1. Refer to the last card of the Piper - Parts Price List - Aerofiche, for a checklist of current revision dates
to Piper Inspection Reports and Manuals.
2. 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 inspections.
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 Number 60297-16 for this airplane, dated March 1973). Any changes issued to the
engine manufacturer's operator's manual after this date 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 and the specified
octane fuel is used. (Refer to latest revision of Textron Lycoming Service Bulletin No. 480.) Should
fuel other than the specified octane rating for the power plant be used, refer to the latest revision of
Lycoming Service Letter No. L185 for additional information and recommended service procedures.
7. Replace or overhaul as required or at engine overhaul. (For engine overhaul, refer to latest revision of
Lycoming Service Instructions No. 1009.)
8. Replace flexible oil, fuel and hydraulic lines in the engine compartment after 8 years or 1000 hours
time-in-service, whichever comes first. Pressure check fluid hoses in the fuselage and wing areas 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 checked again after the next 5 years time-in-service.
9. Piper Service Bulletin No. 435 applies to aircraft with serial numbers 28-7415001 to 28-7515228 inclu-
sive, and must be accomplished at each ten (10) hours of operation, until compliance is made with Piper
Kit No. 760 847v, Aileron Centering Modification.
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 seats. 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. 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 nei-
ther harmful nor detrimental to engine performance and operation. If it can be proven that leakage
exceeded these conditions, the cylinder should be replaced.
