## Summary

This document proposes the supersedure of two existing airworthiness directives (AD), applicable to British Aerospace Model BAe 146 and Avro 146-RJ series airplanes, that currently require inspections to detect cracking of the upper main fitting of the nose landing gear (NLG), and replacement or repair of cracked parts, if necessary. Those actions were prompted by reports of cracking in the main fittings of the NLG. This action would require that, for certain airplanes, the inspections be accomplished at reduced intervals. This proposal is prompted by the results of new analyses of the cracking that were conducted by the manufacturer of the NLG. The actions specified by the proposed AD are intended to prevent failure of the main fitting, which could lead to collapse of the NLG during landing.
