            Background: The FAA requires a one-time inspection to identify all alloy steel bolts on the station 1480 bulkhead splice, and detect and correct cracked or broken bolts, which could result in structural damage and rapid decompression of the aircraft.

            Amendment 1 is issued in response to a new FAA AD which requires accomplishment of the previously optional terminating action.

            The original issue of this Airworthiness Directive became effective on 11 July 2002.
