Airworthiness Directives; Cessna Aircraft Company Models T303, 402C, 404, 414A, and 421C Airplanes

Resumo

This amendment supersedes AD 93-05-03, which currently requires repetitively inspecting each fuel inlet float valve in accordance with certain test procedures on Cessna Aircraft Company (Cessna) Models T303, 402C, 404, 414A, and 421C airplanes, and replacing any valve that does not pass this test. The manufacturer has developed fuel inlet float valves of improved design, and the Federal Aviation Administration (FAA) has determined that the improved valves should be installed to reduce the number of repetitive tests currently required by AD 93-05-03. This action requires installing these fuel inlet float valves of improved design. The actions specified by this AD are intended to prevent possible loss of engine power caused by failure of a fuel inlet float valve.
