Airworthiness Directives; Cessna Aircraft Company Model 172RG Airplanes

الملخص

This document proposes to adopt a new airworthiness directive (AD) that would apply to certain Cessna Aircraft Company (Cessna) Model 172 airplanes. The proposed AD would require you to inspect the main landing gear pivot assemblies for cracks, replace any cracked main landing gear pivot assemblies, and install new bushings on the pivot assembly shaft. Many service difficulty reports of cracked main landing gear pivot assemblies on the affected airplanes prompted the proposed action. The actions specified by the proposed AD are intended to detect, correct, and prevent future cracks on the original design landing gear pivots. Cracked main landing gear pivots could fail resulting in gear-up landings or loss of braking.
