Airworthiness Directives; BAE Systems (Operations) Limited Airplanes

We are superseding Airworthiness Directive (AD) 2010-10-13, for all BAE Systems (Operations) Limited Model BAe 146 and Avro 146 series airplanes. AD 2010-10-13 required repetitive inspections of the wing fixed leading edge and front spar structure for corrosion and cracking, and repair if necessary. This new AD requires revised inspection procedures that terminate a previously approved inspection procedure. This AD was prompted by revised inspection procedures issued by the Design Approval Holder (DAH). We are issuing this AD to detect and correct corrosion and cracking of the wing fixed leading edge and front spar structure, which could result in reduced structural integrity of the airplane.
