Plain English Summary

2/10 complexity

This mandatory Airworthiness Directive requires owners/operators of Piper PA-42 Cheyenne III series aircraft to inspect the main landing gear forward side brace for cracking (initially before 500 hours TIS and then every 50 hours, plus after any gear overspeed) and to retire specific brace part numbers at 800 hours TIS. Installing the improved replacement parts permanently satisfies the AD. It prevents brace failure and possible main-gear collapse on landing.

Note: The incorporation of new improved MLG forward side brace P/N 85165-02/- 03 constitutes terminating action for the inspection and retirement requirements of this AD.

Background: Cracking has been experienced in the main landing gear foward side braces. Failure of a brace could cause landing gear collapse. This amendment reflects the manufacturer’s announcement of the availability of an improved MLG side brace.
