Yerevan

The airplane departed Tbilisi Airport at 1039LT on a cargo flight to Yerevan, carrying five crew members and a load of various goods for a total weight of 2,394 kilos. The assigned altitude of 3,000 meters was reached 17 minutes later and the crew continued to the south under VFR mode. The airplane passed over Idzhevan VOR at 1108LT and six minutes later, the crew was cleared to descent to 1,800 meters by the approach ATC. Between 1116LT and 1119LT, the crew reported twice that the weather conditions deteriorated with low clouds and requested the permission to return to Tbilisi under VFR at 3,000 meters. A minute later, while cruising at the altitude of 2,265 meters, the left wing struck the west slope of Mt Getantag. The airplane continued for 130 meters then crashed in flames. The flight engineer was seriously injured while four other occupants were killed. Few hours later, the only survivor died from his injuries.

The aircraft departed Yerevan-Zvartnots Airport at 0838LT bound for Stepanavan. Weather conditions on the first part of the leg was marginal and poor over the mountains with clouds and rain falls. While cruising at an altitude of 2,320 meters in the clouds, the pilot made a turn to the left when the airplane struck the slope of a mountain located 10 km southwest of Stepanavan Airport. Both pilots and a passenger were injured while all 16 other occupants were killed.

The crew left Yerevan Airport at 0513LT for a meteorological survey mission and completed several maneuvers between 3,500 and 5,000 meters in cloudy conditions over the region of the Sevan Lake. Following an uneventful mission, the crew decided to return to Yerevan and started the descent from the northeast when, at an altitude of 3,160 meters, the airplane hit the east slope of Mt Kara-Dag (3,231 meters high) located about 12 km west of the village of Tsaghkachen. Rescuers arrived on site a day later and all six occupants have been killed.

After dropping an engineer at Sevan Airfield, the pilot took off on a return leg to Yerevan. Shortly after liftoff, while climbing to a height of 25-35 metres, the airplane entered a sharp turn to the left then nosed down and crashed. The pilot, sole on board, died 4 hours later from injuries sustained.

The single engine airplane was completing a mail flight from Yerevan to Abaryan, carrying one mechanic, one pilot and a load of 119 kg of mail. Ten minutes after takeoff, while flying at an insufficient height, the airplane impacted the snow covered ground, overturned and crashed. Both occupants were injured and the airplane was destroyed.

The single engine airplane departed Basargechar at 1550LT on a cargo flight to Yerevan, carrying one pilot and a load of 240 kg of tobacco. While cruising in clouds over the Akhmangan Mountain Range, the airplane went out of control and impacted the slope of Mt Akh-Dag (3,454 metres high). As the airplane failed to arrive at destination, SAR operations were initiated but were eventually suspended on 15 January 1937. The wreckage was found on 26 August 1937. The aircraft was destroyed and the pilot was killed.

Following an uneventful flight from Yerevan, the airplane was approaching the destination at an altitude of 1,000 metres when the pilot initiated a straight-in approach, which is against the published procedures that request a circuit vertical to the airfield. Doing so, the pilot deviated from the approach path. Once at a height of 50 metres, he attempted to go around when the engine failed. The airplane lost height and crashed one km from the airport. Both occupants were killed.
