Détails:
The DC-10 was unloaded following a charter flight. Company maintenance personnel had placed damaged passenger seatbacks (incorporating solid-state chemical oxygen generators) in the forward cargo hold with seat covers and oil. A company mechanic examined the seatbacks to find a serviceable unit. He encountered a loose oxygen generator, which he handled improperly by its oxygen hose. The generator went off by accident, generating a 430deg C heat. Seat covers ignited and the fire eventually burned through the cabin floor. The cabin was soon engulfed in flames.

CONTRIBUTING FACTORS
