During the initial climb after a normal takeoff from Runway 13 at Hong Kong International Airport, as
the aircraft passed through about 1,600 feet, the No 2 engine fire warning sounded. The appropriate
fire drill was actioned and the fire warning ceased within 30 seconds. An emergency was declared and
the aircraft jettisoned about 110 tonnes of fuel before returning to land at Hong Kong.
After landing, when the aircraft had returned to its stand, a brake temperature warning was observed
and the crew was advised by Air Traffic Control that flames were visible around the left body landing
gear. The fire service was already in attendance and quickly suppressed the No 7 brake fire. Because
the aircraft was already on the stand, the emergency slides were not deployed, the passengers being
disembarked rapidly through the jetties without any injuries being suffered.
On site examination of the No 2 engine revealed that there had been a fire around the lower half of the core engine which had severely damaged the covering panels which form the inner diameter of the by-pass duct. The lower core cover panels were removed and the fire was seen to have affected the underside of the whole core compressor module. The lower half of the core engine was sprayed with dye penetrant developer, to act as a leak detection agent, and the engine was then motored over on its starter with the fuel cocks 'open' to test for fuel leaks. Although no leaks were revealed by this procedure, the damage was sufficiently serious to require the engine to be changed
