What happened
A cargo operation traveling from Turukhansk toward Lake Munduiskoye resulted in a fatal accident when the aircraft struck terrain. During the flight, the crew attempted to navigate using Visual Flight Rules (VFR) despite the presence of low-hanging clouds that obscured visibility.
As the flight progressed, the aircraft drifted away from its intended route and entered cloud cover. The plane subsequently impacted a rocky hill slope at an altitude of 395 meters. The terrain involved in the collision, situated approximately 72 km northwest of Turukhansk, was not identified on the crew's navigational charts. The impact resulted in 3 fatalities among the crew members.
Findings
The investigation determined that the primary factor in the accident was that the crew continued to operate under VFR protocols despite encountering weather conditions that were unsuitable for such flight rules.
