Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to all British Aerospace Model BAe 146-100A, -200A, and -300A airplanes. This proposal would require repetitive inspections for cracking of fuselage frame 29, and repair, if necessary. This proposal is prompted by testing that revealed fatigue cracking in the web and inboard flange of frame 29. The actions specified by the proposed AD are intended to prevent reduced structural integrity of the fuselage, due to fatigue cracking in frame 29.
