Circumstances:

During an approach to Moscow-Sheremetyevo Airport in marginal weather conditions, the crew initiated a go-around for unknown reason. During the second approach, at a distance of 5 km from the runway 07 threshold, the crew was informed by ATC that his position was 15 meters below the glide. Shortly later, the airplane nosed down then crashed in a huge explosion 4,330 meters short of runway. The aircraft disintegrated on impact and all 25 occupants were killed.

Probable cause:

The commission considered that the most probable cause of the accident was an adverse combination of the following factors:
- Icing of the stabilizer (probably due to lack of heating in the leading edge),
- A pitch manoeuvre executed to correct a deviation from the glide path which resulted in a g-loading of 0,6 - 0,5,
- Extension of the flaps to the full landing setting, which had the effect of degrading the airflow over the lower surface of the stabilizer and, consequently, of producing loads on the control column which promoted a further increase in the negative g-loading and prevented recovery of the aircraft from the developing nosedive.
Owing the destruction of the aircraft it was not possible to check the actual functioning of the stabilizer deicing system.

Circumstances:

At 2354LT, while cruising at an altitude of 5,700 meters in good weather conditions, the crew was cleared to descend to 4,500 meters and confirmed his ETA in Perm in 15 minutes. Less than two minutes later, the airplane went out of control and entered a dive and reached the speed of 1,000 km/h. At 2,700 meters, the captain was able to regain control for few seconds when the airplane made an upward looping and started to lose parts due to excessive g loads. Out of control, it went down and eventually crashed at a speed of 250 km/h in a field covered by 70 cm of snow and located near Petukhovo, about 90 km north of Perm. The wreckage was found at 1400LT on January 22 and all 39 occupants have been killed. It was later reported that four passengers survived the crash but died due to extreme low temperature (-41° C) before the rescuers arrived on site.

Probable cause:

The exact cause of the accident could not be determined with certainty. It is believed that traces of explosives were found on several debris but this was not proven and the Soviet Authorities confirmed there were no military activities in the area at the time of the accident.

Circumstances:

The single engine airplane was engaged in a charter flight from Bulun to Tiksi, carrying three crew members, 21 schoolboys and a load of fish (three bags). Prior to takeoff, the copilot and the flight engineer informed the captain about the fact that the aircraft was overloaded but the captain decided to take off. Shortly after rotation, while climbing to a height of 20-25 meters, the airplane nosed up and reached a critical angle of attack. The captain elected to make an emergency landing when control was lost and the airplane crashed in a field. All 24 occupants were injured and the aircraft was destroyed.

Probable cause:

Poor flight preparation on part of the captain and wrong decisions.

Circumstances:

A McDonnell Douglas DC-8-62 passenger plane, JA8040, was destroyed when it crashed on takeoff from Moscow's -Sheremetyevo Airport (SVO), Russia. Five of the 14 crew members and ten of the 62 passengers survived the accident. JAL flight JL446 was a scheduled international flight from Copenhagen (CPH), Denmark to Tokyo-Haneda (HND), Japan with an en route stop in Moscow. The flight to Moscow was uneventful and the airplane landed at 18:17. After servicing of the aircraft startup and taxi clearance was received at 19:38. JL446 was cleared for takeoff from runway 25 at 19:49. On takeoff the DC-8 climbed to 100 m with a supercritical angle of attack and lost height abruptly. It hit the ground and burst into flames.

Probable cause:

The cause of the disaster to aircraft DC-8-62 JA-8040 resided in the fact that during take-off and following attainment of the safety speed V2, the crew put the aircraft into a supercritical angle of attack which resulted in loss of speed and altitude. The aircraft's assumption of supercritical angles of attack was the consequence of one of the following circumstances:
- Inadvertent extension of the spoilers in flight, leading to a fall in the maximum value of the lift ratio and an increase in drag;
- Loss of control of the aircraft by the crew in conditions associated with malfunctioning of the No. 1 or No. 2 engine consequent upon possible ice formation on the engine intake at a time when the de-icing system was switched off.
The anomalies in the functioning of the engines observed by the crew and other witnesses may have arisen after the aircraft had assumed a supercritical angle of attack with the spoilers extended.
