Circumstances:

The crew was completing a positioning flight from Krasnoyarsk to Yakutsk with an intermediate stop in Lensk. The intended destination was in fact Prokovsk located about 70 km southwest of Yakutsk but the airfield was not suitable for night movements. On approach to Yakutsk-Magan Airport, the crew continued to Prokovsk where several cars were parked along the runway with their lights ON. Due to low visibility caused by night and snow falls, the crew was unable to establish a visual contact with the ground and two approaches were missed. During a third attempt to land, the aircraft collided with pine trees and power cables and crashed in an open field, bursting into flames. All three occupants were killed.

Probable cause:

The decision of the crew to land on an airfield that was not equipped for night movements.

Circumstances:

En route from Sangar to Yakutsk-Magan Airport, while cruising at an altitude of 1,000 metres in snow falls, the engine failed. The aircraft lost height and the crew attempted an emergency landing when the aircraft struck trees and crashed in a swampy and wooded area located 45 km from Sangar. All 13 occupants were injured and the aircraft was damaged beyond repair.

Probable cause:

Failure of the engine in flight after melted snow and ice entered the engine air intake. The following contributing factors were identified:
- The crew failed to feather the propeller after the engine failed, causing high drag,
- The crew modified his route and continued the prescribed altitude,
- Weather conditions were poor and did not allow to fly under VFR mode,
- Lack of ATC assistance.

Circumstances:

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:

On final approach to Aldan Airport, at a speed of 196 km/h, the crew extended the flaps to 42° when the aircraft adopted a 42,5° nose-up attitude. The crew elected to go-around but, as the speed dropped to 52 km/h, the aircraft stalled and crashed 273 metres short of runway and 160 metres to the left of its extended centreline. The aircraft was destroyed by impact forces and all 24 occupants were killed.

Probable cause:

It was determined that the total weight of the aircraft was 623 kilos above MTOW while departing Yakutsk Airport and 550 kilos above the max landing weight upon arrival at Aldan Airport. More than 400 kilos of bagages were placed in the rear compartment, causing the CofG to be out of permissible limits.

Circumstances:

Following an uneventful flight from Moscow-Domodedovo Airport, the crew started the approach to Yakutsk-Intl Airport. Due to poor weather conditions and a visibility below minima, the crew diverted to Magan Airport. The aircraft overflew the runway threshold at a height of 22 meters and a speed of 297 km/h. It 'floated' for 22 seconds and eventually landed 1,647 meters past the runway threshold. For unknown reasons, the captain maintained the aircraft in a nose-up attitude and the nose gear landed nine seconds after the first touchdown only. Reverse thrust were not activated and the spoilers were finally deployed but too late. At a distance of 47 meters from the runway end, the captain shut down all four engine when the aircraft overran at a speed of 167 km/h. It went down an embankment, lost its undercarriage and came 538 meters past the runway end, 3,978 meters from the runway threshold and 2,331 meters from the touchdown point. Four passengers were injured and 185 other occupants were evacuated safely. The aircraft was damaged beyond repair.

Probable cause:

The accident was the consequence of a poor planned approach and a wrong approach configuration. The following contributing factors were reported:
- Lack of crew training,
- It was the first time (except for one crew member) that the crew was landing at Yakutsk-Magan Airport,
- Marginal weather conditions (visibility below minimums at the initial destination airport),
- Failure to comply with flight crew recommandations,
- Poor crew instructions and interaction,
- The crew failed to follow the published procedures for a standard approach and landing,
- Deviations in aircraft piloting during approach and landing, causing the aircraft to land too far down the runway,
- The pilot-in-command maintained the aircraft in a nose-up attitude for a period of 9 seconds between the main gear touchdown and the nose gear landing,
- The reverse thrust systems were not activated,
- The spoilers were deployed too late,
- Lack of leadership on part of the captain during the approach and landing,
- The crew did not make the decision to initiate a go-around procedure when the landing maneuver was obviously missed.
