1988 - American 132
This incident presaged a disaster years later in the crash of the Valujet
in the Everglades.
On 3 February 1988, a spontaneous chemical fire smouldered out of sight
in the cargo hold of American Airlines Flight 132. On final approach
to land, the cabin floor was softening, sinking and simply melting under
tremendous heat. A deadheading Co-pilot riding in the passenger cabin
who observed the floor told the Co-pilot in the cockpit, '[We're] gonna
have to land this thing in a hurry.'
Until this moment, the flight was nothing but routine.
A McDonnell Douglas DC-9, registration N569AA, Flight 132 had departed
Dallas-Fort Worth at 14.45 that afternoon destined for Nashville. There
were 120 passengers, four flight attendants, and two deadheading flight
crew members aboard. The cargo holds contained 6,365 pounds of airfreight.
There was a 20-pound cylinder of oxygen and a 104-pound drum of textile
treatment chemicals, including five gallons of hydrogen peroxide solution,
an oxidizer and 25 pounds of a sodium orthosilicate-based mixture, which
is a granular solid material. No labels marked the drum to indicate
the hazards of its contents. The oxygen cylinder and the drum were put
in the middle cargo hold; the drum was laid on its side.
The Captain ordered the evacuation two minutes and six seconds after
Flight 132 touched down, and the inflatable slides were deployed at
the two forward cabin doors, the aft galley door and at in the tail
cone. The overwing exits were not used. No instructions were given to
the passengers over the public address system. Neither were they prepared
for the evacuation before landing. During the evacuation, the flight
attendants shouted commands at the passengers to 'Unfasten seat belts'
and 'Come this way' and 'Remove shoes' and 'Don't take anything with
After the passengers had safely evacuated the airplane, an American
Airlines maintenance employee on the ground asked the Captain about
the problem. The Captain said there was a fire in the cargo area. They
opened the aft cargo compartment and saw little smoke inside. Then they
opened the middle cargo compartment. Thick, white/grey smoke poured
The Tower's call dispatched 14 firefighters with six vehicles, four
crash-fire rescue units and two quick response Units to the aircraft,
which had pulled to a stop on the apron beside the runway. The emergency
units sprayed about 120 gallons of water into the middle cargo compartment
to douse the smouldering fires. Neither aqueous film-forming foam nor
dry chemicals to fight fires was used.
None of the 126 crew and passengers was injured seriously; nine passengers
and four crew suffered minor injuries.
