Plain English Summary

3/10 complexity

This Airworthiness Directive (Australia, Civil Aviation Regulations) requires all BAe 146 aircraft to have the main landing-gear main fitting serviced per British Aerospace Service Bulletin 32-73. It must be done before each gear reaches 12,000 landings or within 1,000 landings after 1 March 1989, whichever is later.

The AD was issued because testing indicated fatigue/material defects in the main fitting that could lead to gear collapse. It mandates the service bulletin’s actions (technical detail delegated there) but does not specify costs or who pays.
