Airworthiness Directive · Amendment 39-9969 · BAE Systems (Operations) Limited Airplanes
BAE Systems (Operations) Limited Airplanes
This AD applies to BAE Systems (Operations) Limited Avro 146-RJ100A, Avro 146-RJ70A, Avro 146-RJ85A, BAe 146-100A, BAe 146-200A, BAe 146-300A.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment supersedes 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 amendment requires that, for certain airplanes, the inspections be accomplished at reduced intervals. This amendment is prompted by the results of new analyses of the cracking that were conducted by the manufacturer of the NLG. The actions specified by this AD are intended to prevent failure of the main fitting, which could lead to collapse of the NLG during landing.
