Summary
We propose to adopt a new airworthiness directive (AD) for certain BAE SYSTEMS (OPERATIONS) LIMITED Model BAe 146 and Avro 146-RJ airplanes. This proposed AD was prompted by a report of a crack found on the left-hand sidewall well on the nose landing gear (NLG). This proposed AD would require performing a repetitive high frequency eddy current inspection of the stiffeners on the left-hand sidewall on the NLG gear bay for cracks, and repair or replace the sidewall if necessary. Replacing the sidewall with a certain sidewall part number constitutes a terminating action for the repetitive inspections. We are proposing this AD to detect and correct failure of the sidewall, which could result in consequent in-flight rapid decompression of the cabin and injury to the passengers.
