Narrative:
On 21 June 2003, during the routine maintenance investigation of a reported defect, a short circuit condition was detected on the Fuel Quantity Indication wiring for fuel tank No 7. Damage was found to an associated wire bundle which had been caused by a localised fire within the area enclosed by the wing/fuselage fairing area aft of the main landing gear (zone 198) below fuel tank No 3.

Fuel seepage from this tank, in the area of the chafed wire, had collected in a box section fairing support member
and had been ignited, resulting in a short duration, low intensity fire. The ignition source for the fire was identified as a chafed wire for the main tank No 3 fuel pump, which carries 115V AC power, arcing against the aluminium fairing. It was possible that the chafing of this wire had been precipitated during maintenance activity two years prior to the incident when this wiring had been disturbed.

The fire probably occurred during a flight from LHR to JFK on 13 June 2003, although no indications were apparent to the flight crew at that time. Modifications have since been introduced to prevent the build up of fuel in the box section fairing support structure.

Nature of Damage to airframe: Per the AAIB report "Fire damage in under wing area"
