Airworthiness Directive · Amendment 39-8984 · Aerostar Aircraft Corporation Airplanes
Aerostar Aircraft Corporation Airplanes
This AD applies to Aerostar Aircraft Corporation PA-60-600 (Aerostar 600), PA-60-601 (Aerostar 601), PA-60-601P (Aerostar 601P), PA-60-602P (Aerostar 602P), PA-60-700P (Aerostar 700P).
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment supersedes Airworthiness Directive (AD) 92-13-01, which currently requires inspecting the nose landing gear (NLG) drag brace assembly for corrosion on certain Aerostar Aircraft Corporation (Aerostar) PA-60-600 (Aerostar 600) and PA-60-700 (Aerostar 700) series airplanes, and replacing any corroded components. It also requires replacing the existing spring and piston with new corrosion-resistant parts. This action requires replacing the NLG drag link assembly with a new assembly of improved design. The Federal Aviation Administration (FAA) has received several reports of frozen moisture in the cylinder of the over-center release system, which has led to nose gear collapse on airplanes already in compliance with AD 92-13-01. The actions specified by this AD are intended to prevent failure of the NLG caused by frozen moisture in the cylinder, which could lead to nose gear collapse and damage to the airplane.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
