CHEMICALLY GENERATED SUPPLEMENTAL OXYGEN SYSTEMS IN DC-10 AND L-1011 AIRCRAFT

The study examines the problems encountered in four recent decompression incidents with respect to the presentation, understanding, and use of chemically generated supplemental oxygen systems installed in DC-10 and L-1011 aircraft. These problems include lack of oxygen flow indications; headband adjustment difficulties; lack of mask stowage methods; unreliability of oxygen compartment doors; method of oxygen mask presentation; flight attendant training; and passenger briefings. The study finds that there is a need for design guidance from the FAA in the design of supplemental oxygen systems as well as a need for proving these systems by actual demonstration. The Safety Board has made nine safety recommendations to the FAA regarding improvements in training, briefings, use, and design of the supplemental oxygen supplies.
