Supplemental Oxygen

On November 10, 2005, the Federal Aviation Administration (FAA) published a direct final rule to amend its regulation on the use of pilot supplemental oxygen with an effective date of January 9, 2006. The FAA received an adverse comment from the National Transportation Safety Board stating that the FAA relied on time of useful consciousness data that did not represent actual pilot performance under realistic decompression conditions. In accordance with Sec. 11.31, which states if the FAA receives an adverse comment it will notify the public by publishing a document in the Federal Register, the FAA is using this notice to withdraw this direct final rule in whole.
