On August 22,
1985 at 0612 hrs. UTC, a Boeing 737-236, G-BGJL, operated by British
Airtours began it's takeoff roll down runway 24 at Manchester
International Airport. The plane was carrying 131 passengers and 6
crew on a charter flight bound for Corfu.
Approximately 36 seconds later, as the
aircraft's airspeed passed 125 knots, the left engine suffered an
uncontained failure, initiated by a failure in the No 9 combustor
can, which punctured a wing fuel tank access panel. The leaking fuel
ignited and burned as a large plume of fire trailing behind the
engine. The flight crew heard a 'thump' or 'thud' and the takeoff
was immediately aborted, throttles were closed and reverse thrust
was applied to both engines. They cleared the runway onto a taxiway
on the right. They had no indication of fire until about 9 seconds
later. The engine fire extinguishing system was engaged with no
effect due to the fire being external. An evacuation was initiated
from the right side of the aircraft.
Flame penetrated the cabin rapidly due in
part to the orientation of the parked aircraft. The side of the
aircraft that was on fire was facing into the wind, which
subsequently blew the flames towards the fuselage. Despite prompt
attendance by the airport fire service, the aircraft was destroyed
and 55 people on board lost their lives.
This is a classic example of the design
flaw of mounting engines directly below wing fuel tanks. The No 9
combustion can is located in the upper right part of the engine. If
this design had engines mounted in the rear of the aircraft, away
from any fuel tanks, the probability of fire would have been near
zero.
Interestingly enough, the safety
recommendations made by British air accident investigators don't
address this.
Additionally,
only 40% of people engulfed in smoke survived and 8% of those
who did collapsed during the evacuation. The British officials did recommend
the use of smoke hoods for crew and passengers. Try asking for a
smoke hood next time you fly on a commercial airliner!
