The Falcon 50, 900 and 900EX are among the first of several business jets to be the subject of a final AD as a result of the FAA’s special certification review (SCR) of all pressurized airplanes after the October 1999 Payne Stewart Learjet 35 crash and several other incidents and accidents attributed to suspected oxygen deprivation. The AD would require a revision to the jets’ flight manuals to advise the crew to don oxygen masks immediately if there’s a significant change in oxygen or pressurization levels. The FAA said the Falcon flight manual currently suggests that the crew first troubleshoot the pressurization system following changes. However, the FAA has no reports of oxygen-deprivation problems on Falcon jets.
