Abstract
This amendment adopts a new airworthiness directive (AD), applicable to certain Cessna Model 441, 500, 550, and 560 series airplanes, that requires replacement of outflow/safety valves with serviceable valves. This amendment is prompted by a report of cracking and subsequent failure of outflow safety valves in the pressurization system. The actions specified by this AD are intended to prevent such cracking and subsequent failure of the outflow/safety valves, which could result in rapid decompression of the airplane.
