Circumstances:
The Avro York plane carried out a freight flight from Beirut to Tehran via Kuwait. On the Kuwait-Tehran leg of the flight several test manoeuvres were carried out by a check pilot who was examining the pilot in command and co-pilot for renewal of their licenses. Shortly after takeoff, while climbing, the airplane went out of control and crashed in a huge explosion 11 km southeast of Karaj, west of Tehran. The aircraft was completely destroyed upon impact and all four crew members were killed.
Probable cause:
The position of the propellers at the time of impact would indicate that, at a time when the no. 4 engine power was off, an emergency condition developed which necessitated the feathering of no. 3 engine and the unfeathering of no. 4. Alternatively, a loss of power on the starboard engines could have occurred from an erroneous manipulation of the feathering switches during the course of this assumed crew checking exercise. In view of the fact that the fully loaded aircraft was flying at a low altitude after taking off from Mehrabad Airport which has an elevation of 3900 feet, it is evident that at the aircraft would not have sufficient altitude for the pilot to take effective recovery action and so avoid a crash resulting from the above mentioned loss-of-power conditions.

Circumstances:
Following a normal takeoff from Brindisi Airport runway 05, the airplane did not gain height as expected. After reaching a height of 60 m it began to descend gradually, in a slightly banked to port attitude, and struck the sea about 2,250 m from the end of the runway, 4° left of the extended runway centerline. The airplane was destroyed by impact forces and a fire broke out. All six crew members were killed.
Probable cause:
The accident was probably caused by a loss of power on No.1 and 2 engines following takeoff, which resulted in a gradual loss of height. The probable slow psycho-physical reaction of the crew, due to fatigue, may have prevented perception of the danger and the timely execution of manoeuvres to prevent the accident, or minimize its consequences.

Circumstances:
On a cargo flight from Beirut to Tehran, while cruising at an altitude between 13,000 and 15,000 feet by night, the four engine aircraft was attacked by the pilot of an unknown fighter. The engine number one was hit, causing a fire that spread to the nacelle and the wing. Shortly later, the engine number four was shut down and its propeller feathered due to a fuel exhaustion (the fuel tank was apparently empty). In such situation, the crew reduced his altitude and attempted an emergency landing near Rasht. The airplane came to rest in a field and was destroyed. All three crew members were uninjured. It is presumed the crew made a navigation error in flight, causing the aircraft to fly over the Soviet Union without authorization.
Probable cause:
Shut down by an unknown fighter in flight. The accident was attributed to faulty navigation.

Circumstances:
During the takeoff roll at Muscat Airport, the tire on the left main gear burst. The crew continued the takeoff and during initial climb, informed ATC of the situation and received the permission to return for a safe landing. On touchdown, the left main gear collapsed and the airplane slid for dozen yards before coming to rest in flames. All three crew members escaped uninjured while the aircraft was damaged beyond repair.
Probable cause:
Failure of the left main gear on touchdown following a tire burst.

Circumstances:
The aircraft was performing a flight from London to Kabul with several intermediate stops. The stopover at Beirut was longer than expected because few technical issues were noted after the airplane landed from Frankfurt. The departure from Beirut was postponed for 20 hours. Two minutes after departure from runway 18, while climbing, the airplane struck the slope of Mt Aramoun located about 5 km south of the airfield and burst into flames. Three passengers were seriously injured while all 24 other occupants were killed.
Probable cause:
The accident was attributed to a combination of:
- A navigational error in that the pilot did not right turn out as early as he should have, either because he forgot or because he was distracted by some unusual occurrence,
- A fire indication (or possibly a fire) in the number one engine which induced the pilot to start fire emergency action with a resulting reduction in the rate of turn and the rate of climb.
