PROGRAMMED INSPECTION.

The programmed inspection was designed to permit the best utilization of the aircraft, by scheduling
inspections through the use of a planned inspection schedule. This programmed inspection schedule is
prepared in a manual form which is available from Piper Service Sales under Part No. 761 736. Refer to Piper
Parts Price List Aerofiche, last card for revision check list to insure obtaining latest issue.

UNSCHEDULED MAINTENANCE CHECKS.

SPECIAL INSPECTIONS AS REQUIRED, UPON CONDITION.
The special inspections given, supplement the scheduled inspections as outlined in Periodic Inspections, to
include inspections which are required at intervals not compatible with airframe operating time or inspection
intervals. Typical of this type are:
1. Inspections required because of special conditions or incidents that arise, and because of these
conditions or incidents, an immediate inspection would be required to insure further safe flight.
2. Hard or Overweight Landing. This inspection should be performed after a known rough landing is
made or when a landing is made while the aircraft is known to exceed the design landing weight. Check the
following areas and items:
Wings - for wrinkled skins, loose or missing rivets.
Fuel leaks around the fuel tanks.
Wing spar webs, bulkheads, wing and fuselage stringers and skins for any signs of overstress or
damage.
A possible alignment check to clarify any doubt of damage.
3. Severe Turbulence Inspection. The same items and locations should be checked as stated for Hard or
Overweight Landings along with the following:
Top and bottom fuselage skins for loose or missing rivets and wrinkled skins.
Empennage skins and attachments.
4. Engine overspeed, sudden stoppage, loss of oil, overtemperature and lightning strike. Check with
Avco Lycoming for necessary corrective action.
