Department of Transportation March 21, 2016 – Federal Register Recent Federal Regulation Documents

We propose to supersede Airworthiness Directive (AD) 2014-13- 12, for all Airbus Model A318, A319, A320, and A321 series airplanes. AD 2014-13-12 currently requires identifying the part number and serial number of each passenger oxygen container, replacing the oxygen generator manifold of any affected oxygen container with a serviceable manifold, and performing an operational check of the manual mask release, and doing corrective actions if necessary. Since we issued AD 2014-13-12, we have determined that affected containers have not only been marked with company name B/E Aerospace, as was specified, but also, for a brief period, with the former company name DAe Systems. This proposed AD would retain the requirements of AD 2014-13-12, and require replacing the oxygen generator manifold of any affected DAe oxygen container with a serviceable manifold. We are proposing this AD to detect and correct nonserviceable oxygen generator manifolds, which could reduce or block the oxygen supply and result in injury to passengers when oxygen supply is needed.
