Circumstances:
On a cargo flight from Stalinabad to Kulyab when the right wing caught fire some 20 minutes into the flight (probably due to a leak in a fuel pipe). The fuel tanks in the right wing exploded, the aircraft dove into the ground and crashed into rocks in the Rangon Mountain Range located southeast of Stalinabad. All three crew members were killed.
Probable cause:
The Tadjik investigation commission reported that the accident was caused by several errors committed by the crew. The NII GVF inspection disagreed with these results and reported that the crash may have been caused by a technical issue on a fuel line (carburetor and/or collector) linked to the right BMW-132 engine.

Circumstances:
The airplane departed Stalinabad on a flight to Khorugh, carrying six passengers (four adults and two children) and one pilot. En route, weather conditions deteriorated and the visibility was poor. Despite the situation, the pilot decided to continue. Flying in clouds, the airplane struck a rock and crashed in deep snow at an altitude of 3,900 metres near the Odudi Pass. All seven occupants survived the accident with minor injuries but without any food and in extreme conditions with very low outside temperature. Twelve days after the accident, the pilot and three passengers tried to find help and left the crash site. During this trip, a passenger died of cold. On May 12, an expedition was sent to the crash site and found a woman and her two children aged one and nine died of cold and hunger.
Probable cause:
The following factors were determined:
- The weather briefing transmitted to the pilot prior to the flight did not reflect the truth and reported good weather conditions all along the route from Stalinabad to Khorugh,
- The pilot decided to continue the flight despite the lack of visibility due to poor weather conditions and failed to return to his departure point.

Circumstances:
Following a flight from Dushanbe, the single engine airplane crashed upon landing at Khorugh Airfield and was damaged beyond repair.
Probable cause:

Circumstances:
The airplane departed Kulob Airport at 1100LT on a schedule service to Stalinabad, carrying 11 passengers (nine adults and two children), two pilots and a total of 265 kg of luggage. Ten minutes after takeoff, while cruising at an altitude of 940 metres above a mountainous area, one of the engine failed. The crew attempted to make an emergency landing but there were no suitable terrain. The airplane lost height and impacted the slope of a rocky mountain (slope of 60°) located 18 km northwest of Kulob. The wreckage was found less than an hour later some 15 metres below the summit. The airplane disintegrated on impact and all 13 occupants were killed.
Probable cause:
Due to the degree of destruction of the airplane and the lack of witnesses, the exact circumstances of the accident could not be determined. Nevertheless, one of the engine failed in flight, most probably due to the failure of a fuel supply and/or the carburetor where irregular and abnormal wears were found, because of a poor polish during the last repair session.

Probable cause:
The pilot was inexperienced and this was his first solo flight. Failure of the Authority at Stalinabad Airport who allowed the pilot to take off despite poor weather conditions at destination and his lack of experience.

After 10 km, he decided to return but while making a sharp turn to the left at a height of 25-30 metres, the airplane stalled and crashed on the slope of Mt Yafush. the pilot was killed.
Probable cause:
The pilot failed to follow the published procedures and entered a narrow valley instead following the normal route to Jirgatal.

Circumstances:
The single engine airplane departed Kulob Airport at 1650LT on a cargo flight to Stalinabad, carrying one pilot and six bags of corn for a total weight of 425 kg. After takeoff, the pilot made several circuits over the airport to reach the altitude of 800 metres then sets course for Stalinabad. About 10 minutes later, while cruising at an altitude of 300 metres, the engine failed. The pilot attempted to make an emergency landing but there was not suitable terrain. Out of control, the airplane crashed on hilly terrain located about 10 km from Kulob. The aircraft was destroyed and the pilot was killed.
Probable cause:
The accident was the result of an engine failure due to the failure of the lower head of the 3rd cylinder connecting rod as a result of poor heat treatment. The accident occurred in an area that did not allow the pilot to make an emergency landing, which was considered as a contributing factor.

Circumstances:
The airplane departed Stalinabad on a regular service to Kulob, carrying four passengers, two pilots and a load of 502 kg of various goods, 97 kg of mail and 54 kg of luggage. Following a downwind leg, while flying over the runway at a height of 10 metres, ready for landing, the pilot-in-command increased the engine power and initiated a go-around procedure. The airplane climbed to a height of 30 metres in an excessive nose-up attitude then stalled and crashed, bursting into flames. The aircraft was totally destroyed and all six occupants were killed.
Probable cause:
The accident was the consequence of a series of errors on part of the pilot-in-command who, following a downwind approach, initiated a go-around as the landing procedure was obviously missed. At that point, he increased the throttle too sharply while the stabilizers were not in the correct position, resulting in the aircraft entering an excessive nose-up attitude followed by an aerodynamic stall.
The following contributing factors were identified:
- No technical anomalies were found with the aircraft, its equipment or the engine;
- Wrong approach configuration;
- Incorrect actions during the go-around procedure;
- Lack of discipline;
- Overconfidence of the captain;
- Crew fatigue;
- Absence of a crew work conditions monitoring system.
