Responding to the crew, the ATC cleared flight CX780 for a priority landing and also alerted the emergency services by declaring a local standby.Īt the later end of the descent, the Captain took control of the aircraft in accordance with Cathay Pacific’s standard operating procedures for one engine inoperative. The crew requested the shortest possible route for a priority landing. However, two more ECAM messages were then annunciated: “ENG 1 SLOW RESPONSE” and “AVOID RAPID THRUST CHANGES”.Ī few moments later they declared a “PAN PAN” with Hong Kong ATC and advised that the No. To compensate for the low thrust of the No. 2 thrust lever accordingly to the IDLE position. The flight crew completed the necessary ECAM procedures and set the No. According to the captain, a light “pop” sound was heard, and some “ozone” and “burning” smell was detected shortly before the ECAM message “ENG 2 STALL”. While the aircraft was approximately 110 nautical miles southeast of Hong Kong International Airport, the aircraft’s ECAM displayed two error messages, “ENG 1 CTL SYS FAULT” and “ENG 2 STALL”, within a short period of time. Image via Twitter Descent and Approach to Hong Kong This time as well all engine parameters were normal and the flight was deemed safe to continue on to Hong Kong. Once again, the flight crew contacted a maintenance engineer who responded to the call and confirmed that he was aware of the earlier situation as they had been monitoring the engine parameters during the flight. Engine anti-ice for both engines was selected “ON” by the flight crew for the purpose of checking its effect on the EPR fluctuation but apparently, it had no effect on the fluctuation. This time ECAM information “AVOID RAPID THR CHANGES” was also displayed in addition to the “ENG 2 SLOW RESPONSE”. As all engine parameters were considered normal other than the EPR fluctuations, the flight crew elected to continue the flight to Hong Kong.Īlmost two hours into the flight, the ECAM message “ENG 2 CTL SYS FAULT” reappeared when the aircraft was levelling off at F元80. The flight crew consulted with a maintenance engineer regarding the issue who advised the flight crew to maintain the engine control at “EPR” mode. ECAM information “ENG 2 SLOW RESPONSE” was shown for crew awareness. Shortly after levelling off at F元90, the Electronic Centralised Aircraft Monitoring (ECAM) displayed an “ENG 2 CTL SYS FAULT” message. 1 engine also had abnormal EPR fluctuations but within a narrower range. However, during the climb, the flight crew noticed some abnormal Engine Pressure Ratio (EPR) fluctuations on the No. According to the flight crew, the flight did not encounter any significant weather en route, which was confirmed by the satellite imageries for the period. Meanwhile, F/O Hayhoe had been working for Cathay Pacific for 3 years after serving 11 years with the Royal Australian Air Force.įlight CX780 left the stand, departed uneventfully from Surabaya’s Runway 28 under Visual Meteorological Conditions (VMC), and was away from any significant weather. Captain Waters had been flying for Cathay Pacific for 12 years. Moreover, the F/O was the Pilot Flying (PF) for the flight, and the Captain was the Pilot Monitoring (PM). The 35-year-old captain was accompanied by First Officer David Hayhoe, who had 4,050 total flight hours. Flight CX780 was under the command of Captain Malcolm Waters who had 7,756 total flight hours, including 2,601 flight hours in the Airbus A330. The Cathay Pacific Airbus A330-300 with registration B-HLL was performing flight CX780 from Surabaya, Indonesia to Hong Kong with 309 passengers and 13 crew members on board. However, due to fuel contamination, both of the engines sustained damage and the aircraft landed at almost twice the normal speed due to loss of thrust control on approach. On 13th April 2010, a Cathay Pacific Airbus A330 was operating flight 780 from Surabaya to Hong Kong.
