Airworthiness Directives; Cessna Aircraft Company 150, 152, 172, 177, 180, 182, 185, 188, 206, 207, 210, and 337 Series Airplanes

概要

This document proposes to adopt a new airworthiness directive (AD) that would apply to Cessna Aircraft Company (Cessna) Model 150, 152, 172, 177, 180, 182, 185, 188, 206, 207, 210, and 337 series airplanes. The proposed AD would require measuring the visible length of standpipe (tube) in the top assembly of the fuel strainer assembly for the correct length, and replacing any fuel strainer assembly that does not have the correct length of standpipe. This action is prompted by reports that the fuel strainer assemblies on the affected airplanes were manufactured with the fuel standpipes incorrectly installed in the assembly housing top. The actions specified by the proposed AD are intended to prevent foreign material from entering the fuel system and engine, which could result in loss of engine power or complete engine stoppage during flight.
