Event Summary

On November 18, 2019, at 12:28 local time, an Aero AT-3 aircraft registered as HA-BHL was conducting a training flight at Tököl airport (LHTL). The student pilot, on his first solo flight, lost control during takeoff.

No personal injuries were sustained, but the aircraft was damaged beyond repair.

Aircraft and Flight Details

The aircraft was an Aero AT-3, registration HA-BHL, used for pilot training. The student and his instructor had arrived at the airport around 08:00 to conduct training flights for a private pilot license. The first flight, lasting 1 hour and 30 minutes, involved emergency procedure practice and was performed at Kiskunlacháza airport. After returning to Tököl and a half-hour break, they completed a second flight of 1 hour for a checkout circuit. Following a 20-minute break, the instructor released the student for his first solo flight. During pre-takeoff checks, the engine achieved 4900 rpm at full throttle instead of the specified 5050 rpm. The flight school mechanic advised that this reduction was not significant enough to affect task performance, and the first two flights were conducted without issue.
