Airworthiness Directive · Amendment 39-10659 · British Aerospace Model BAe 146 and Model Avro 146-RJ Series Airplanes
British Aerospace Model BAe 146 and Model Avro 146-RJ Series Airplanes
Model BAe 146 and Model Avro 146-RJ series airplanes, as listed in British Aerospace Service Bulletin SB.57-49, Revision 1, dated June 19, 1997, and having wing skins made from 7150-T651 aluminum; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain British Aerospace Model BAe 146 and Model Avro 146-RJ series airplanes, that requires repetitive detailed visual inspections of the top wing skins for stress corrosion cracks, damage, or missing surface protective finish of the metallic surfaces; and repair, if necessary. This amendment is prompted by reports of stress corrosion cracks found on the top wing skin during routine inspection on three airplanes. The actions specified by this AD are intended to detect and correct such cracking, which could result in reduced structural integrity of the wing.
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.
