Flight 57 departed at 21:41 local time, August 2. The flight towards Igarka was uneventful. Visibility at Igarka was limited due to fog. The flight was cleared for an approach to runway 12. The crew continued the approach below 100 m even though they had not established positive visual contact with the runway.
The airplane drifted to the right until it struck trees at a distance of 477m short of the runway and 234 meters to the right of extended centreline. It came to rest after sliding 140 m through trees. A fire broke out, destroying the aircraft. All eleven passengers and one crew member were killed in the accident.
Rosaviatsia reported the weather at the time of the approach to be: clouds at 220 meters, visibility 3.5 km02:00, rain, wind 150 ░ 3 m / sec.
CONCLUSION: (translation from Russian original)
The cause of the crash of AN-24RV RA-46524 was the execution of an approach in conditions worse than the weather minima of the airfield, aircraft, and pilot. The failure of the crew to take a timely decision for a missed approach when the plane descended below the minimum safe height (100m) in the absence of reliable visual contact with approach lights and runway lights. This caused the aircraft to strike trees and the ground in controlled flight.
Factors contributing to shortcomings in the meteorological services of this flight were:
- Incorrect weather forecast with regards to cloud ceiling, visibility and severe weather - fog.
- Inaccurate information about the actual weather on the glide path at the Middle Marker with course 117░, radioed to the crew 40 minutes before the accident.
The timely implementation of recommendations to improve meteorological support operations developed by the Commission to investigate the crash of Tu-134A RA-65021, which occurred at the airport Kurumoch, Samara March 17, 2007, could have prevented the crash of AN-24RV RA-46524.
