MAINTENANCE MANUAL
K. NOTES
1. Refer to Piper’s Customer Service Information Aerofiche P/N 1753-755, for latest revision
dates to Piper Inspection Reports/Manuals and this maintenance manual. References to
Section are to the appropriate Section in this manual.
WARNING: INSTRUCTIONS FOR CONTINUED AIRWORTHINESS (ICA) FOR ALL NON-
PIPER APPROVED STC INSTALLATIONS ARE NOT INCLUDED IN THIS
MANUAL. WHEN A NON-PIPER APPROVED STC INSTALLATION IS
INCORPORATED ON THE AIRPLANE, THOSE PORTIONS OF THE AIRPLANE
AFFECTED BY THE INSTALLATION MUST BE INSPECTED IN ACCORDANCE
WITH THE ICA PUBLISHED BY THE OWNER OF THE STC. SINCE NON-PIPER
APPROVED STC INSTALLATIONS MAY CHANGE SYSTEMS INTERFACE,
OPERATING CHARACTERISTICS AND COMPONENT LOADS OR STRESSES
ON ADJACENT STRUCTURES, THE PIPER PROVIDED ICA MAY NOT BE
VALID FOR AIRPLANES SO MODIFIED.
2. Inspections or operations are to be performed as indicated by a “O” at the 50 to 100 hour
inspection interval. Inspections or operations (i.e. - component overhauls/replacements, etc.)
required outside the 100 hour cycle are listed as special inspections in section 5-30-00.
Inspections must be accompanied by persons authorized by the FAA.
(a) The 50 hour inspection accomplishes preventative maintenance, lubrication and servicing
as well as inspecting critical components.
(b) The 100 hour inspection is a complete inspection of the airplane, identical to an annual
inspection.
NOTE: A log book entry should be made upon completion of any inspections.
3. Piper Service Bulletins are of special importance and Piper considers compliance mandatory.
In all cases, see Service Bulletin/Service Letter Index P/N 762-332 or Service Bulletin/Service
Letter Aerofiche Set P/N 1762-331 to verify latest revision.
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 ( 60297-27 ) 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. On new engines, check after the first 25 hours of operation, then at each subsequent 50 hour
inspection.
7. Cover or remove all filters, plug all openings, cover the ignition lead at the spark plug and
magneto. Solvent will contaminate the air and fuel filters and will corrode the springs in the
ignition leads.
8. 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 airplane is returned to service.
Heavy discoloration and the appearance of seepage at the cylinder head and barrel
attachment area are 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 should be
replaced.
