FINAL AIR INCIDENT INVESTIGATION REPORT №. 16/2010, DATED 6th FEBRUARY 2012
HISTORY OF THE FLIGHT
On 27th October 2010, Ilyushin 76 TD, EK76442, operated by Phoenix Avia, departed the cargo stand at Dubai International Airport at approximately 0300 LT (UTC+4), then reached to RWY 12R via entry M4 at approximately 0313. According to the crew statements, the AFM dictates that one of the line-up checks is to advance the four engines’ power to 80% for 1 minute period and check all the engines’ related parameters including oil pressure and temperature, RPM, EGT and vibration. In the incident flight, the captain advanced the engines power to 80% and kept monitoring the relevant indicators. After approximately 20 seconds of power advancement, the PIC observed low oil pressure on engine no. 2 indicator associated with vibration red alert, accordingly he retarded engine 2 throttle lever and instructed the Flight Engineer to switch engine 2 off by the engine fuel cut handle located at the middle pedestal, the other three throttle leavers were also retarded to lower power setting.
The crew reported to Dubai ATC that they had engine problem and they should return to the stand for further inspection, they were instructed to clear RWY 12R via exit M5 and to park at cargo stand E23 where the crew disembarked normally. No emergency was declared.
The Air Accident Investigation Department determines that the probable cause of engine No. 2 failure was internal damage caused by heat stress resulting from the use of highly contaminated fuel.
