Oxygen

The FAA has issued an airworthiness directive for certain Bombardier Challenger 300s as a result of reports of deformation found at the neck of the pressure regulator body on the oxygen cylinder and regulator assembly (CRA). It requires an inspection to determine if a specified oxygen CRA is installed and to replace affected oxygen CRAs.

In February 2011 the FAA issued an Airworthiness Directive calling for removal of chemical oxygen generators from airplane lavatories, or emptying the generator and restowing the masks. (By the way, no one told the passengers that there was no longer any supplemental oxygen supply in the bathrooms.) While security wasn’t mentioned in the AD, apparently there was a safety problem. Or as the FAA so confoundingly put it in the new final rule, which rescinds the 2011 AD, “This AD was prompted by reports that the current design of the oxygen generators presents a hazard that could jeopardize flight safety. We are issuing this AD to eliminate a hazard that could jeopardize flight safety and to ensure that all lavatories have a supplemental oxygen supply.”

The FAA has issued an airworthiness directive (AD) for the Bombardier Challenger 300 prompted by reports of deformation found at the neck of the pressure regulator body on the oxygen cylinder and regulator assembly (CRA). The AD requires an inspection to determine if a certain oxygen CRA is installed and the replacement of affected oxygen CRAs.

A seven-month investigation by the U.S. Air Force Scientific Advisory Board into unexplained hypoxia, or oxygen deprivation, incidents experienced by F-22 pilots has not determined the root cause of the problem, the service said March 29. The investigation did produce a number of safety recommendations, and the Air Force continues to study the problem.

The U.S. Air Force approved a resumption of flight operations by the Lockheed Martin F-22 Raptor, ending a four-month standdown ordered after pilots experienced symptoms of hypoxia. The suspected source of the problem, the aircraft’s onboard oxygen generation system (Obogs), remains under study.

Embry-Riddle Aeronautical University has taken delivery of a Mentor advanced aircraft training device built by Frasca. The trainer will be used in studies of hypoxia, or oxygen deprivation, in the university’s Normobaric lab. The Mentor replicates a Cessna 172 cockpit complete with Garmin G1000 avionics and a Truvision visual system.

Oxygen bottle levels are an important preflight item, but even with a full bottle, pilots still need to do some calculating to determine if there is enough oxygen for a planned flight and in case of a diversion.

How much oxygen do you need to make sure you’re not only legal for a planned flight but can also safely provide for crew and passengers in the event of a diversion? Aeronautical Data Systems (ADS), based in Upper Saddle River, N.J., has developed Web-based software that helps answer this question easily and comprehensively.
