Circumstances:
The crew was completing a ferry flight from Veliky Ustyug to Vologda and initiated the descent by night and poor weather conditions with fog and reduced visibility. On short final, the aircraft passed below the glide and at a height of 20 meters, it struck trees and crashed in flames in a wooded area located short of runway threshold. The aircraft was totally destroyed by impact forces and a post crash fire and three crew members were killed while two others were seriously injured. At the time of the accident, the visibility was 700 meters, well below minimums, but the crew was informed about a visibility of 1,500 meters.
Probable cause:
It was determined that people at Vologda Airport (ATC, meteo,...) falsified weather bulletins to allow certain aircraft to land. The crew was also blamed to let the aircraft descending below the glide without any visual contact with the runway lights.

Circumstances:
En route from Anchorage to Galena, the pilot encountered poor weather conditions with low ceiling. Lost and disoriented, he flew into a blind canyon when he saw high obstructions. While initiating an evasive maneuver to avoid collision, he made a steep turn to the left when the aircraft struck the ground and crashed in flames in a mountainous terrain located about 125 miles northwest from the city of Anchorage. As the airplane failed to arrive at destination, SAR operations were initiated but eventually abandoned few days later as no trace of the aircraft nor the pilot was found. On September 2, 1980, the burnt wreckage was found near Rainy Pass.
Probable cause:
Controlled flight into terrain after the pilot became lost and disoriented. The following contributing factors were reported:
- The pilot continued VFR flight into adverse weather conditions,
- The pilot misjudged distance, speed, altitude or clearance,
- Low ceiling,
- High obstructions,
- The pilot flew into blind canyon,
- Evasive maneuver to avoid collision,
- In-flight steep left turn,
