Final rule; partial revised compliance date.

The Federal Aviation Administration (FAA) is extending the compliance date for batteries installed in automated external defibrillators (AEDs) to meet the requirements of a Technical Standard Order (TSO). The primary manufacturer of AEDs has only recently applied for approval of its battery. Not enough approved batteries exist to equip the entire air carrier fleet by the original compliance date of April 12, 2004. Extension of the compliance date will have a negligible impact on safety, will allow AEDs to continue to be used, and will allow for further approval and production of batteries that meet the TSO requirements.
