Airworthiness Directives; British Aerospace Model BAe 146 and Avro 146-RJ Series Airplanes

Riepilogo

This amendment adopts a new airworthiness directive (AD), applicable to all British Aerospace Model BAe 146 series airplanes and certain British Aerospace Model Avro 146-RJ series airplanes, that requires repetitive eddy current inspections to detect fatigue cracking along the face of the retraction attachment boss in the nose landing gear sidewall; and corrective action, if necessary. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil aviation authority. The actions specified by this AD are intended to detect and correct fatigue cracking along the face of the retraction attachment boss in the nose landing gear sidewall, which could result in premature extension of the nose landing gear or depressurization of the airplane.
