Airworthiness Directives; Cessna Aircraft Company 150, 172, 175, 180, 182, 185, 206, 210, and 336 Series Airplanes

Краткое содержание

This document proposes to adopt a new airworthiness directive (AD) that would apply to certain Cessna Aircraft Company (Cessna) 150, 172, 175, 180, 182, 185, 206, 210, and 336 series airplanes. The proposed AD would affect those airplanes equipped with 0513166 series plastic control wheels. The proposed AD would require you to repetitively inspect these wheels for cracks, conduct a pull test on these wheels, and replace any control wheel with a crack or that does not pass the pull test. Replacement of the control wheels would be with ones that are FAA-approved and are not 0513166 series plastic control wheels. The proposed AD is the result of many incidents of control wheels cracking or breaking on the above-referenced airplanes. The actions specified by the proposed AD are intended to detect and correct cracked or defective control wheels, which could result in loss of control of the airplane during takeoff, landing, or ground operations.
