## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain British Aerospace Model Avro 146-RJ70A, -RJ85A, and -RJ100A airplanes. This proposal would require repetitive inspections for cracking of fuselage frame 29, and repair, if necessary. This proposal is prompted by results of fatigue testing, which 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.
