Ust-Nera | Bureau of Aircraft Accidents Archives

The single engine airplane departed Ust-Nera on a cargo flight to Vyun, carrying two pilots and a load of various equipment destined for the employees of a local gold mine. Upon landing on an unprepared terrain, the undercarriage collapsed. The airplane slid on its belly and came to rest. Both pilots escaped uninjured and the aircraft was damaged beyond repair. The accident occurred at location N 65° 54' E 138° 20'.

Probable cause:

The accident was the result of the destruction of the right main landing gear strut upon landing.
The following contributing factors were identified:
- Unsatisfactory performance of the welded joint in the manufacture of the strut with the formation of welding cracks in one of the most stressed zones of the strut,
- Pilot errors, which led to an early landing of the aircraft, possibly rough, on an unprepared (uncleared) area with possible obstacles.

Circumstances:

On approach to Ust-Nera Airport, following an uneventful flight from Khandyga, the crew mistook the new runway 85 (still under construction) for the operational runway 75 in poor visibility. When ATC realized this, they twice ordered the crew to go around but the crew failed to comply and touched down on runway 85. During the landing run, at a speed of 158 km/h, the captain attempted to go around but the check pilot aborted this attempt some seconds later. The confused flight engineer retracted the landing gear and the aircraft came to rest on its belly, suffering substantial damage. All 5 crew and 24 passengers escaped unhurt.

Probable cause:

The following findings were reported:
- Poor approach and landing planning,
- The crew descended below MDA without visual contact with the runway,
- The crew failed to comply with ATC instructions,
- Poor crew coordination,
- The flight engineer mistakenly raised the landing gear while the aircraft was still on ground.

Aircraft flight hours:

Circumstances:

The crew encountered low clouds and poor weather conditions while following the valley of the river Tikhon-Yuryakh. The decision to return was taken too late so the aircraft was unable to clear the obstacles. It struck tree tops and crashed at a height of 1,080 meters into a mountain slope located near the Moma Pass (1,444 meters high) and 19 km northeast of Chumpu-Kytyl (Tyubelyakh). The aircraft was destroyed by impact forces and a post impact fire. A pilot and a passenger were injured while the second pilot and five passengers were killed.

Probable cause:

The accident was the consequence of:
- Wrong decisions taken by the crew,
- Poor flight preparation,
- Insufficient or erroneous information about enroute weather conditions.
