Okha | Bureau of Aircraft Accidents Archives

The aircraft was completing a cargo flight from Petropavlovsk-Kamchatsky to Novosibirsk with intermediate stops in Okha and Chita, carrying a load consisting of three Toyota vehicles and boxes of frozen fish. While completing a turn to join the approach path, one engine failed. The crew continued the approach when, on short final, the second engine failed as well. The aircraft lost height and crashed 1,657 metres short of runway. A passenger was seriously injured while 13 other occupants were killed. Few hours later, the only survivor died from his injuries.

Probable cause:

Double engine failure on approach caused by a fuel exhaustion. At the time of the accident, the total weight of the aircraft was 5 tons above the max landing weight.

Circumstances:

The single engine aircraft was completing a local skydiving mission at Okha Airport on behalf of the Yuzhno-Sakhalinsk Aeroklub. After takeoff, while climbing to a height of about 50 meters, the aircraft stalled and crashed in a snow covered field. Three skydivers were killed while all 12 other occupants were injured.

Probable cause:

It was determined that the total weight of the aircraft was well above the MTOW while the CofG was too far aft the limit. The stall occurred at a too low altitude to expect recovery.

Circumstances:

Shortly after takeoff from Okha Airport, while on a cargo flight from Okha to Tsimmermanovka, the single engine airplane entered thick fog at a height of some 35-40 metres. The pilot decided to make a 180 turn when the airplane lost speed, stalled and crashed on the shore of the Pyervaya Bukhta Bay located northwest of the airport. The aircraft was destroyed by impact forces and a post crash fire and both pilots were killed.

Probable cause:

Loss of control and aerodynamic stall during the last turn due to an insufficient speed. The pilot inexperience in clouds and the presence of low clouds were considered as contributing factors.

Circumstances:

The crew departed Nikolayevsk-on-Amur on a mail flight to Okha. Few minutes after takeoff, he encountered poor weather conditions and the visibility dropped below minima due to snow falls. In such conditions, the crew decided to return to his departure point but lost orientation and failed to realize his altitude was insufficient. While cruising at an altitude of 190 meters in limited visibility, the single engine struck trees and crashed on the wooded slope of a hill (282 metres high) located 4,1 km from the runway's centerline. The airplane was destroyed by impact forces and a post crash fire and both pilots were killed.

Probable cause:

Poor flight preparation on part of the crew who decided to takeoff without any information related to the weather conditions enroute. Local meteorologists transmitted information to the crew afterwards but these information were considered as too optimistic and failed to reflect the truth.

Circumstances:

The airplane departed Okha in good weather conditions, carrying three passengers and one pilot to Aleksandrovsk-Sakhalinski. About 15 minutes into the flight, weather conditions worsened and the visibility was poor due to snow falls. The pilot reduced his altitude and continued along the shore. In a visibility estimated to be 15-20 metres, the pilot failed to realize he was too low. In a slight turn, the airplane impacted the ground and crashed on a icy area located in the Tatar Strait, about one km off the village of Lukolovo. The aircraft was destroyed and all four occupants were killed.

Probable cause:

Controlled flight into terrain after the pilot continued the flight at an insufficient altitude in poor visibility (15-20 metres) due to snow falls. Information transmitted to the crew regarding weather conditions en route were erroneous and did not reflect the actual conditions.
