## Abstract

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 pumps for 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 detect and 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.
