Airworthiness Directives: Aerostar Aircraft Corporation PA-60-600 (Aerostar 600) and PA-60-700 (Aerostar 700) Series Airplanes

요약

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.
