SUMMARY: The FAA is adopting a new airworthiness
directive (AD) for all Aerostar Aircraft Corporation (Aerostar)
Models PA-60-600, PA-60-601, PA-60-601P, PA-60-602P, and PA-60-700P
airplanes that incorporate supplemental type certificate (STC)
SA1608NM (Machen Inc. Kit No. 76-1 Auxiliary Fuel
Tank). This AD requires you to repetitively inspect all
auxiliary fuel transfer pumpsfor leaks, seeping, or any sign of
staining. This AD also requires you to replace any pump found with
leaks, seeping, and any sign of staining. This AD is the result of
reports of fuel leaking from the fuel transfer pumps installed
below the auxiliary fuel tank. We are issuing this AD to detectand
correct leaks in the auxiliary fuel transfer pumps, which could
result in fire or explosion in the cargo/passenger compartment.
Such a condition could result in loss of the airplane.
