Aeroflot Flight 36 was a regularly scheduled passenger flight operated by Aeroflot from Cairo International Airport to Bykovo Airport. On 17 August 1960, the Ilyushin Il-18 operating this flight crashed after an engine fire. All 27 passengers and seven crew members were killed.
The Air Accident Investigation Commission determined that a externally leaking fuel injector was the root cause of the accident.
Accident
Flight 36 was at cruising altitude and had just passed the check point at Codra, Kiev, when at 15:52 the crew reported to air traffic control (ATC) that they had feathered the prop of engine #4 and requested an emergency landing attempt at Boryspil International Airport. At 15:57 Flight 36 reported the #4 engine and right wing were on fire. ATC recommended landing at Kyiv International Airport (Zhuliany) which was closer, but then at 1557:30 the crew made a last radio transmission "We’re falling, falling, goodbye, falling, falling, falling ...”. The airliner crashed approximately 41 km north of Kyiv International Airport (Zhuliany). There were no survivors.[1][2]
Aircraft
Construction of the Il-18B involved, serial number 189001702 017-02, was completed at Moscow Banner of Labor production factory in 1960 and it was transferred to the civil air fleet. It was powered by four Ivchenko AI-20 turboprop engines and at the time of the accident, the aircraft had sustained a total of 407 flight hours and 117 takeoff/landing cycles.[1][3][4]
Investigation
The aircraft created a deep cone-shaped crater at impact, destroying much of the airframe. The flight data recorder was damaged beyond recovery of any data but the Air Accident Investigation Commission were able to determine that the engines were set to idle power, the flaps, spoilers and landing gear were all in the retracted position and that rudder trim was full right with the left aileron trim full up.[1][2]
Weather along the flight route was calm and ruled out as a possible cause.[1]
Investigators looked into the possibility that the aircraft collided in flight with an unmanned military vehicle or a weather balloon but no evidence surfaced. The commission found no evidence of an in flight aircraft failure or structural break up. The right engine and other sections of the aircraft displayed damage due to fire and investigators considered that a fire in flight may have caused the accident. An examination of the victims found no smoke had been inhaled and further analysis of the crash site determined all fire damage occurred during the post crash fire so this possibility was ruled out.[1][2]
The investigators were able to conclude that full deflection of the rudder and left aileron trim would have significant effects on control of the aircraft at cruising speed but the chain of events leading to the accident was never determined.[1][2]
