Circumstances:
The crew started the approach to Yuzhno-Sakhalinsk by night and heavy rain falls. On short final, the captain realized he was well above the glide so he decided to increase the rate of descent. The airplane struck the runway surface nose first at a speed of 230 km/h and with a positive acceleration of 2,8 g. It bounced then landed a second time with an acceleration of 3,8 g. Upon impact, the nose gear was torn off, the engine number one detached and both wings were bent. Out of control, the airplane slid for several yards before coming to rest. All occupants escaped uninjured while the aircraft was damaged beyond repair.
Probable cause:
Wrong approach configuration on part of the pilot-in-command. Poor crew coordination and poor weather conditions were considered as contributing factors.

Circumstances:
Following an uneventful flight from Khabarovsk, the crew received the permission to descend to Yuzhno-Sakhalinsk Airport but was instructed to maintain a minimum altitude of 600 meters. By night, while in a flat attitude but slightly banked to the right, the airplane struck trees, stalled and crashed in a dense wooded area located on Mt Ufa, some 26 km northwest of the airport. Six passengers (three adults and three children) were seriously injured while 87 other occupants, among them all nine crew members, were killed.
Probable cause:
The crew failed to comply with the published procedures and started the descent prematurely, causing the aircraft to approach below the minimum safe altitude. The following factors were considered as contributing:
- Poor flight preparation,
- Lack of visibility,
- Lack of radar availability at destination airport.

Circumstances:
The crew started the approach to Yuzhno-Sakhalisnk from the southeast in marginal weather conditions due to low clouds. At an altitude of 400 meters, the aircraft hit tree tops and crashed inverted in a wooded area located on the slope of Mt Komissarskaya (714 meters high) located 13,5 km southeast of the airport. The wreckage was found a day later and a passenger was found alive but seriously injured while all 26 other occupants were killed. The aircraft was totally destroyed upon impact.
Crew:
Vasily Trofimovich Degtyarenko, pilot,
Vladimir Parkhomenko, copilot,
Vyacheslav Fedorovitch Eliseikina, mechanic,
Daniel Epifanovich Raznotsvete, mechanic,
Piotr D. Novikov , radio navigator.
Probable cause:
The radio navigator mistook two outer markers when the crew started the approach to Yuzhno-Sakhalinsk Airport, and referred to the outer marker of the Korsakov Airbase (frequency 684 kHz) instead of the outer marker of the civil airport of Yuzhno-Sakhalinsk-Bolchaya Yelan (frequency 670 kHz). Investigations reported that these two outer markers were too close from each other (13,5 km) with close frequency as well, which contributed to the mistake. The following factors were also pointed out: lack of visibility caused by low clouds (the crew failed to distinguish the mountain); the crew failed to use the radio altimeter and an abnormal action on part of the crew regarding the direction finder unit.

Circumstances:
The single engine airplane departed Aleksandrovsk-Sakhalinski on a flight to Khabarovsk, carrying two passengers, one pilot and a load of 75 kg of mail. About 14 minutes into the flight, the pilot entered an area of fog. As the visibility was poor, he reduced his altitude and descended relatively fast when he lost control of the airplane that crashed on the icy Tatar Strait, about 3 km off the village of Khoe. The aircraft was destroyed and all three occupants were killed.
Probable cause:
The pilot made the decision to continue the flight in difficult weather conditions, which probably exacerbated the nervous tension and the illness from which he suffered. It is likely that he lost consciousness as he began the steep descent, due to the fact that he was suffering from chronic sclerotic inflammation of the meninges, which could lead to epileptic seizures with loss of consciousness. He had lost consciousness in 1940 at Okha Airport.

Circumstances:
The float plane was scheduled to depart Aleksandrovsk-Sakhalinsky on a regular service to Khabarovsk with an intermediate stop in Viakhtu, carrying three passengers and four crew members. Several times during the day, the takeoff was postponed due to swell and strong winds. At each time, the crew spotted wooden logs floating on water. In the evening, as the weather seems to be a little better, the crew decided to take off, facing wind. During the takeoff roll, shortly prior to rotation, the airplane collided with wooded logs. Both floats were partially torn off, the airplane nosed down and plunged into the water, coming to rest few hundred metres offshore. Six people were quickly rescued while a passenger drowned. The aircraft was towed to shore but later considered as damaged beyond repair.
Probable cause:
Collision with wooden logs while taking off from. Poor flight preparation on part of the crew who failed to ensure that the takeoff area was cleared of obstacles.

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.
