Investigation Summary
During the descent into Samara (then Kuibyshev), Captain Alexander Kliuyev made a bet with First Officer Gennady Zhirnov that he could land the aircraft using only instruments, despite the weather being clear. To facilitate this, Kliuyev ordered the flight engineer to draw the cockpit window blinds. The crew ignored Ground Proximity Warning System (GPWS) alerts at approximately 62-65 meters (203-213 feet) and failed to execute a go-around. One second before touchdown, the captain ordered the blinds to be opened; the flight engineer complied, but the sudden transition left the captain no time to adapt to visual flight. The aircraft struck the runway at 280 km/h (150 knots) with a vertical load of 4.8g and a vertical speed of 5 m/s. This led to a structural failure of the left wing and a massive fuel fire. The aircraft rolled over and came to rest upside down 70 meters left of the runway axis. While the First Officer survived the initial impact and attempted to rescue passengers, he died of cardiac arrest on the way to the hospital. Official Soviet reports at the time varied, with some top-secret documents citing 75 total deaths (64 at the scene and 11 in hospital) compared to the public figure of 70.
Final Conclusions
The accident was caused by the gross negligence and reckless behavior of the captain, who intentionally disregarded safety protocols and visual flight rules for a personal bet. The lack of intervention from the First Officer and Flight Engineer highlighted significant failures in Crew Resource Management (CRM) and cockpit discipline within the airline at the time.
