Category: Accident
A An-2 aircraft experienced a sudden left turn and crash during a flapless takeoff with strong winds of up to 15 m/s and a temperature of -15øC at a height of 50-60 meters. The aircraft abruptly entered a large bank angle exceeding 45ø, leading to a loss of height and subsequent crash.A An-2 aircraft experienced a sudden left turn and crash during a flapless takeoff with strong winds of up to 15 m/s and a temperature of -15øC at a height of 50-60 meters.
