On August 10, 1995, a PZL-Mielec AN-2 (registration RA-40371) operated by UraiAvia was involved in an aviation accident near Mezhdurechensky, Russia during takeoff. No fatalities were reported. Investigators recorded the probable cause as: The crew decided to take off despite the total weight of the aircraft being well above MTOW, because 23 passengers, including 10 children, embarked illegally. This summary draws on records from the Bureau of Aircraft Accidents Archives (B3A).
Shortly after takeoff from Mezhdurechensky Airport, an aircraft on a forest patrol flight to Uray lacked sufficient engine power, struck power cables, stalled, and crashed 2 km away. All 25 occupants were injured, four seriously, and the aircraft was destroyed. Investigators found that 23 passengers, including 10 children, embarked illegally, causing weight above MTOW.
Accident Sequence
The aircraft departed from Mezhdurechensky Airport on a forest patrol flight to Uray. Shortly after takeoff, the engine lacked sufficient power, preventing the aircraft from gaining adequate altitude. While flying at low height, the aircraft struck power cables, entered a stall, and crashed approximately 2 kilometers from the airfield.
Injuries and Damage
All 25 occupants sustained injuries in the accident. Four individuals were seriously hurt. The aircraft was damaged beyond repair.
Investigation Findings
The investigation determined that 23 passengers, including 10 children, had boarded the aircraft illegally. This resulted in a total weight far exceeding the maximum takeoff weight (MTOW). The crew chose to proceed with takeoff despite the overweight condition.
Probable cause
The crew decided to take off despite the total weight of the aircraft being well above MTOW, because 23 passengers, including 10 children, embarked illegally.
