From the Wikipedia article
The Il-12 crash at Magdagachi was an aviation accident involving an Il-12 aircraft of Aeroflot that occurred on Wednesday, 4 November 1953 near Magdagachi airport, killing 5 people.
Crash
The aircraft was operating mail flight 5 from Irkutsk to Khabarovsk with intermediate stops in Chita and Magdagachi. At 10:03 the airliner took off from Irkutsk and 1 hour 5 minutes later landed safely in Chita. Then at 12:58 flight 5 took off from Chita for Magdagachi and after climbing took up flight level 3000 metres. At 14:24, proceeding at this flight level, the aircraft entered the area of responsibility of the control centre in Magdagachi, and at 15:41, having already descended to flight level 1200 metres, it also entered the zone of Magdagachi airport. The airport controller cleared flight 5 to descend to the height of the traffic circuit with a pressure setting of 728.2 mm Hg. The crew then received clearance to land on a heading of 300°, as well as the landing conditions (north-westerly wind 4 m/s, clear, visibility 15 kilometres), after which it began the approach. At this time it was a clear moonless night. The airport's flight director watched as the Il-12 approached the airport on a heading reciprocal to the landing heading, made the third turn, and then disappeared from view. Several minutes passed, after which a glow suddenly appeared in the area of the fourth turn.
As was established, between the first and second turns the airliner approached the airfield at a height of approximately 600 metres. When the commander received clearance to land, he did not fly a full check circuit but immediately began the landing approach. However, when the Il-12 completed the fourth turn, it began catching the tops of trees with its wing. After flying like this for 160 metres, the aircraft then struck the trunk of a thick tree with its left wing, as a result of which the wing was partially destroyed. The airliner soared sharply upward, then, rotating to the left about its axis, turned over "onto its back", after which at 15:55 (21:55 local time), 358 metres from the point of first collision with the trees, it struck the ground at an angle of about 45°. The aircraft was completely destroyed and burned, and all five people on board died.
Investigation and cause
Investigation
It was established that all the aircraft's systems had been working properly before the collision. Having examined the left altimeter (on the commander's side), the investigators determined that the pressure on it had been set to 733.2 mm Hg, that is, 5 mm Hg higher than the controller had given. Such a difference caused the altitude readings to be overstated by 55 metres. The readings of the right altimeter (on the co-pilot's side) could not be determined. Also, during the approach the commander delayed the fourth turn, as a result of which it was performed 1–1.5 kilometres further out than usual, and moreover over terrain that was 100 metres above the level of the airfield, and that is without taking into account the trees growing on it. Thus, when the aircraft was rolling out of the fourth turn, with altimeter readings of 175–180 metres it was actually 20–25 metres above the ground, and therefore, while 5620 metres from the airport, it began catching trees with its wing. There were also errors in the actions of the flight director, who showed no initiative in directing the flight, did not require the crew to fly the full check circuit, and when flight 5 disappeared from view, did not take the necessary measures to locate it.
The main cause of the crash, in the commission's opinion, was the incorrect setting of the airfield pressure on the barometric scale of the left altimeter, and also that the pilots thereafter did not monitor the height readings on the radio altimeter. Contributing factors to the crash included the aircraft commander's insufficient practical experience of night flying, which the deputy commander of the Irkutsk Aviation Group failed to detect in time during check flights, and also the unsafe approach procedure with a landing heading of 300°, since just five kilometres south-east of the airport, that is, near the area where the fourth (final) turn is performed, there is terrain that is 100 metres above the level of the airfield.
