Beschrijving:
A sudden decompression at FL330 caused severe damage to the airframe: 19 stringer fittings were damaged at Station 1800, and the rear bulkhead separated from the fuselage crown. The TriStar crew initiated an emergency descent to FL140 and returned to Los Angeles and landed safely at 22:17 hours. Due to the cost of repairs, Delta Airlines subsequently retired the aircraft. The aircraft was purchased by Lockheed Aircraft for aging aircraft testing. On October 11, 1995, the aircraft was ferried to Dobbins AFB, Marietta, GA.

Probable Cause:

PROBABLE CAUSE: "Inadequate certification/approval of the airframe structure. Contributing was the lack of required inspections of the failure area."
