Airplanes certificated in all categories. Compliance required as indicated.

To prevent possible fire or explosion in the area aft of the fire wall in the engine nacelles, accomplish the following:

(a) Within 10 hours time in service from the effective date of this AD, prior to engine start for each flight, check the lower engine nacelle cowling and the lower wing surface just outboard of the engine nacelle for wetting or other indications of fuel leakage. The checks required by this AD may be performed by the pilot.

NOTE 1. Removal of the engine or nacelle cowling is not required to perform this check.

NOTE 2. For the requirements regarding the listing of compliance and method of compliance with this AD in the airplane's permanent maintenance record, see FAR 91.173.

(b) If fuel stains, discoloration or any other signs of leakage are observed, the source of leakage must be determined and the leak repaired prior to further flight.

(c) Within the next ninety (90) days from the effective date of this AD or by the next annual inspection after the effective date of this AD, whichever occurs later, rework the aft nacelle and fire wall area to provide sealing, drainage, and ventilation per Part II of Piper Aerostar Service Bulletin 600-80, dated April 6, 1979.

(d) Pre-flight inspections required by (a) may be discontinued after rework per (c) is accomplished.

(e) Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base for the accomplishment of repairs required by this AD.

(f) Alternative inspections, modifications, or other actions which provide an equivalent level of safety may be used when approved by the Chief, Aircraft Engineering Division, FAA Western Region.

This amendment becomes effective May 24, 1979.
