Investigation Summary
The flight was transporting the leadership of the Soviet Pacific Fleet back to Vladivostok following naval exercises in Leningrad. During the takeoff roll in snowy conditions, the aircraft carried heavy, unsecured cargo, including large rolls of printing paper. As the aircraft accelerated and rotated, these rolls shifted toward the rear of the cabin. Simultaneously, several high-ranking officers had reportedly ignored seating assignments, further biasing the weight toward the aft. This combination moved the center of gravity far beyond the aircraft's certified limits. Upon liftoff, the aircraft pitched up sharply, reaching an altitude of approximately 50 meters before stalling. The crew was unable to force the nose down due to the extreme imbalance. The aircraft rolled into a steep right bank and continued to roll until it was nearly inverted, striking the ground just 20 meters from the end of the runway.
Final Conclusions
The investigation concluded that the primary cause was the improper loading of the aircraft and the failure of the crew to ensure cargo and passengers were correctly positioned. The shifting of heavy printing paper rolls during the takeoff run created an aft center of gravity that made the aircraft aerodynamically unstable in pitch. The influence of high-ranking military officers, who pressured the crew and disregarded safety protocols regarding seating, was cited as a significant contributing factor.

Airframe & Maintenance
Systems & Failure Modes
Weight and Balance
The distribution of mass within the aircraft; the aft shift of cargo moved the center of gravity beyond the point where the elevators could maintain pitch control.
Elevators
Flight control surfaces used to control pitch; they were unable to counteract the extreme nose-up tendency caused by the weight imbalance.
Interesting Facts
- 01The crash killed 16 admirals and generals, including the Commander of the Pacific Fleet, Admiral Emil Spiridonov.
- 02One person was ejected from the nose of the aircraft and found alive in the snow, but died en route to the hospital, resulting in zero long-term survivors.
- 03The aircraft (MSN 76600402) was completed on July 26, 1957, and originally registered as CCCP-L5426 for Aeroflot's Far East division.
- 04The aircraft was re-registered as CCCP-42332 in 1959 and transferred to the Soviet Navy on October 6, 1961.
- 05The accident effectively beheaded the leadership of the Soviet Pacific Fleet, leading to a significant temporary loss of operational capability.
- 06The cargo included heavy rolls of printing paper that were not properly secured for flight.
Safety Actions & Advisories
Cargo Securing Protocols
The accident highlighted the critical necessity of securing all cabin cargo, leading to stricter enforcement of loading procedures within Soviet military aviation.
Command Authority
The crash served as a case study in the dangers of 'rank-based' pressure on flight crews, reinforcing that the pilot-in-command has final authority over safety regardless of passenger rank.
