Summary
On 10 January 2005 at 15:50 local time, a Reims Aviation F152, registration HB-CCF, overturned during a touch-and-go landing at Beromünster airport, 17 km north-northwest of Lucerne. The student pilot was uninjured; the aircraft sustained total damage.
Flight History
Earlier that day, the instructor and student conducted a training flight with two full-stop landings. The instructor assessed the grass runway as slightly soft but suitable. The student then flew solo, performing exercises in a practice area before returning for touch-and-go landings. The student landed within the first 150 meters of runway 34 and applied full power. The aircraft did not accelerate sufficiently to reach takeoff speed, leading the student to abort the takeoff and apply brakes. The nosewheel was pushed into the soft ground, and the aircraft overturned slowly.
Aircraft and Pilot Information
The aircraft was a Reims Aviation RA F152, HB-CCF, a two-seat, single-engine high-wing monoplane. Its empty weight was 535.7 kg; the estimated takeoff mass at the time was 650 kg, within the maximum of 758 kg. The student pilot held a PPL issued by the FAA (2000) and had 94:54 total flight hours, with 88:06 on type. The instructor had 4158 total hours, including 3106 as an instructor.
Cause and Contributing Factors
The accident was caused by overturning following excessive braking on a soft runway. Contributing factors were inadequate takeoff technique during the touch-and-go and the instructor's order to perform a touch-and-go that was not adapted to the student's training level.
