Circumstances:
En route from Podkamennaya Tunguska to Yeniseysk, while cruising at an altitude of 1,500 metres, the engine failed.

All 13 occupants were rescued while the aircraft was damaged beyond repair.
Probable cause:
Engine failure in-flight following carburetor icing. It was reported that the airplane has not been prepared for the winter season by the operator's technicians and remained in summer flight conditions. Following a flight of three hours with an OAT of -30° C, the engine failed after the carburetor got iced.

Circumstances:
The copilot was the pilot-in-command on approach to runway 07 at San José-Juan Santamaría Airport. On final approach, the crew encountered poor weather conditions and limited visibility due to fog and was unable to locate the runway and its lighting system. On short final, the captain realized that the aircraft was not properly aligned on the glide and took over controls. He attempted to correct the trajectory but the unstable aircraft continued to descend and landed to the right of the runway. The aircraft rolled for about 1,500 metres when it struck a drainage ditch. Both main landing gears were torn off and the aircraft came to rest on its belly in a grassy area. All 42 occupants evacuated safely while the aircraft was damaged beyond repair.
Probable cause:
The following factors were reported:
- Poor approach planning,
- Lack of crew coordination,
- The captain failed to initiate a go-around procedure while the aircraft was unstable and not properly aligned,
- Wrong approach configuration,
- Lack of visibility due to poor weather conditions.

Circumstances:
During the takeoff roll on runway 36 at Recife-Guararapes Airport, the right engine failed. The crew decided to continue the takeoff procedure and completed the rotation after a course of 900 metres. Thirty seconds after rotation, at a height of about 100 feet, the right engine caught fire and exploded. The crew lost control of the airplane that crashed in the district of Ipsep near the airport. The aircraft and several buildings were destroyed. All 15 occupants as well as two people on the ground were killed.
Probable cause:
The accident was the consequence of the failure of the right engine during takeoff. It was determined that the temperature indicator for the right engine was faulty, displaying a lower than actual temperature. The engine operated for some time at high temperatures because of the faulty system. It was also found that, after completion, some maintenance and inspection tasks were just signed by the maintenance engineer. Signatures from the maintenance inspector were missing.
The following contributing factors were reported:
- Poor crew reaction to an emergency situation,
- Poor maintenance,
- Manufacturing deficiency,
- The crew failed to abort the takeoff procedure.

Circumstances:
The descent to Makhachkala was started in poor weather conditions. While over mountainous terrain, the crew failed to realize his altitude was insufficient when, at an altitude of 550 metres and at a speed of 366 km/h, the aircraft struck the slope of Mt Kukurtbash (980 metres high) located 23 km from the airport. The aircraft disintegrated on impact and all 51 occupants were killed.
Probable cause:
It was determined that the aircraft was following a wrong approach path to Makhachkala-Uytash Airport following inaccurate ATC instructions. ATC in charge transmitted wrong instructions to the crew, causing the aircraft to be off course and below the minimum prescribed altitude. The crew was unable to see and avoid the mountain due to low clouds in the area and was unaware of his exact position. It was also reported that the crew allowed 47 passengers (39 adults and 8 children) to embark in Elista while 32 seats were available on board. This caused the aircraft to take off with a total weight of 260 kilos above MTOW.
