Circumstances:
Originally, the flight was a direct one from Tokyo-Narita to Seoul but due to poor weather conditions at destination, the crew diverted to Jeju. The aircraft departed Jeju Airport at 2107LT on the final leg to Seoul-Gimpo Airport. At destination, weather conditions were still poor with heavy rain falls and wind from 220 gusting to 22 knots. After touchdown on runway 14R, the crew started the braking procedure but the aircraft deviated to the right and veered off runway. While contacting soft ground, the aircraft lost its undercarriage and came to rest. All 395 occupants evacuated, among them 20 were slightly injured. The aircraft was damaged beyond repair.
Probable cause:
It was determined that the loss of control after touchdown was the consequence of the captain's misuse of the thrust reverser during the landing roll and his confusion over crosswind conditions. Investigations revealed that after touchdown, the n°1 engine thrust reverser did not deploy because the n°1 engine power lever's position did not allow the reverser to be deployed. The following contributing factors were identified:
- Poor weather conditions,
- Cross wind component,
- Wet runway surface,
- Poor braking action.

Circumstances:
The aircraft was completing a flight from Agathi to Thiruvananthapuram with an intermediate stop in Cochin, carrying three passengers and three crew members. After takeoff from runway 17, at a height of about 400 feet, the aircraft pitched up steeply to a near vertical attitude and thereafter appeared to perform a manoeuvre similar to a stall turn to the right and crashed on the roof of the Component Repair Shop (CRS) building of the Naval Aircraft Yard. After impact the aircraft caught fire and was totally destroyed. All six occupants were killed as well as three people in the building. Six others received minor injuries.
Probable cause:
After take off the aircraft pitched up uncontrollably, stalled fell to its right and crashed. The uncontrollable pitch up was caused by sudden uncommanded downward movement of the Trimmable Horizontal Stabilizer leading edge. This was due to partial detachment of its 'actuator forward bearing support' fitting due non installation of required hi-lok fasteners. Poor aircraft maintenance practices at Short Haul Operations Department contributed to the accident.

Circumstances:
After 33,5 seconds during the takeoff roll, after a distance of 975 metres and at a speed of 210 km/h, the engine n°4 failed and its propeller automatically feathered. For unknown reasons, the crew failed to identify this failure and the pilot-in-command started the rotation (elevator -26°) at an insufficient speed of 238 km/h instead of the recommended 250 km/h. After liftoff, the aircraft started to roll to the right, causing the right wing to struck the ground two seconds after rotation. The went out of control, lost its undercarriage, slid for about 300 metres and came to rest, bursting into flames. All nine occupants escaped with various injuries and the aircraft was destroyed by fire.
Probable cause:
Failure of the engine n°4 due to an incorrect setting of the propeller speed control system.

Circumstances:
The aircraft was engaged in a cargo flight from Ras al-Khaimah to Mykolaiv, carrying eight crew members and a load of various goods among them few tons of water melons. Following a night takeoff from runway 34 at a speed of 235 km/h, the aircraft reached the altitude of 150 metres at a speed of 365 km/h then continued to 160 metres at a speed of 400 km/h. The crew raised the flaps in five steps when the aircraft entered an uncontrolled descent with a rate of 12 metres per second until it impacted the sea at a speed of 485 km/h about 16 km from the airport, some 800 metres offshore. The aircraft disintegrated on impact and all eight occupants were killed.
Probable cause:
It was determined that the aircraft was overloaded by 15-25 tons regarding the actual flight conditions and 13-23 tons regarding the MTOW as published in the manuals. At the time of the accident, the OAT was +37° C, reducing climb and flight performances.

The aircraft was engaged in a special flight from Yakutsk to Sangar with an intermediate stop in Kobyay, carrying doctors who came to provide care to local populations. Few minutes after takeoff from Yakutsk-Magan Airport, while cruising at an altitude of 1,150 metres at a speed of 180 km/h, the engine started to vibrate and lost power, Also, the oil pressure dropped and the speed decreased. The captain attempted an emergency landing in a swampy area when the aircraft rolled for about 32 metres and nosed over. A passenger was killed and all other occupants were injured, four seriously.
Probable cause:
Engine failure following the failure of the first cylinder and piston due to fatigue.

Circumstances:
While approaching Dhaka-Tejgaon Airport at an altitude of 4,000 feet, the crew encountered technical problems with the right engine they shut down. Few seconds later, the crew was able to restart the right engine but as the temperature of the turbine increased, he shut down the engine again. This time, he was unable to feather the propeller. Due to excessive drag, the aircraft lost height and the captain attempted an emergency landing in an open field. On landing, the aircraft lost its undercarriage and came to rest. All seven occupants escaped uninjured while the aircraft was damaged beyond repair.
Probable cause:
Failure of the right engine for unknown reasons. Failure of the automatic propeller pitch control mechanism was a contributing factor.
