Confidence Rating: Accident investigation report completed and information captured
A Lockheed L-100-30 Hercules transport plane, operated by Lynden Air Cargo, diverted to Iliamna Airport, Alaska following a rapid in-flight decompression.
The aircraft departed Bethel, Alaska at 06:50 hours local time on a flight to Elmendorf Air Force Base near Anchorage. The airplane climbed to the planned cruising altitude of FL250. At 07:11, upon reaching 24500 feet, there was an in-flight decompression. The flight crew initiated an emergency descent to FL120, which was reached at 07:16 hours. The flight then diverted to Iliamna were a safe landing was carried out at 08:05 hours.
Examination of the airplane revealed a large hole in the forward pressure bulkhead canted web.

The next day the aircraft was ferried to Anchorage and from there to Kelowna, BC, Canada at an altitude of 10000 feet.

PROBABLE CAUSE: "The fatigue failure of the forward pressure bulkhead canted web that originated from stress corrosion cracking areas. Contributing to the failure were inspection procedures and intervals inadequate to identify the crack."
