Circumstances:
The single engine aircraft departed Yerevan-Erebuni Airport at 1047LT on a cargo flight to Kamo, carrying two pilots and a load of 140 kilos of mail and various goods. At that time, weather conditions were considered as good. Six minutes later, the crew informed ATC about his position at an altitude of 1,800 meters and was cleared to climb to 2,400 meters. Then the aircraft entered a right turn and struck the south slope of Mt Gantusar (2,299 meters high) about two km northeast of Jraber. The wreckage was found at an altitude of 1,915 meters and both pilots were killed. It was reported that the visibility at the accident site was about 60 meters due to thick fog.
Probable cause:
It was determined that weather conditions deteriorated en route with limited visibility due to foggy conditions, and the crew took the decision to continue the flight in below minimums visibility instead of returning to Yerevan Airport.

Circumstances:
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.
Probable cause:
The pilot suffered a spatial disorientation while flying in clouds over mountainous terrain, causing a loss of control and a subsequent impact with terrain.
The following contributing factors were identified:
- The decision to fly another route over mountains was in violation of the published procedures,
- The number of daylight hours after takeoff from Basargechar was insufficient.
