June 2008 - ABX Air 1611 |
On June 28, 2008, a 767, registration N799AX operated by ABX Air, caught
fire just aft of the cockpit area while the flight crew were preparing
to start the engines in San Francisco, CA.
The ABX Air Boeing 767-200 was parked at plot no.11 in preparation
for a cargo flight to Airborne Airpark (ILN). A fire occurred just aft
of the cockpit and burned through the top of the fuselage. At the time
of the fire, the airplane was parked near a loading facility, all of
the cargo to be transported on the flight had been loaded, and the doors
had been shut.
The primary location of the fire was outside the cargo hold in an area
just aft of the cockpit. The fire was extinguished by San Francisco
Airport Rescue and Fire Fighting, but not before causing substantial
damage to the aircraft. The flight crew of two, who were preparing to
start the engines when the fire broke out, escaped from the aircraft
without injury.
PROBABLE CAUSE: "The National Transportation Safety Board determines
that the probable cause of this accident was the design of the supplemental
oxygen system hoses and the lack of positive separation between electrical
wiring and electrically conductive oxygen system components. The lack
of positive separation allowed a short circuit to breach a combustible
oxygen hose, release oxygen, and initiate a fire in the supernumerary
compartment that rapidly spread to other areas. Contributing to this
accident was the Federal Aviation Administrations failure to require
the installation of nonconductive oxygen hoses after the safety issue
concerning conductive hoses was initially identified by Boeing."
