Analysis

The crew stated that while at FL370, the cabin alt began to climb. An emergency descent was initiated & after landing the passengers deplaned in a normal manner. Investigation revealed a 9X18' hole in the fuselage about 3 ft foward of the acft cargo door. Metallurgical examination revaled that the crack had occurred as a result of fatique which orginated in scrape marks on the inside of the skin immediately adjacent to the origin of the crack.
