Summary

The Federal Aviation Administration (FAA) has issued an airworthiness directive requiring the replacement of outflow/safety valves with serviceable valves on certain Cessna Model 441, 500, 550, and 560 series airplanes to prevent cracking and subsequent failure of these valves, which could lead to rapid decompression of the aircraft.
