Accident Sequence
On 10 April 2015 at 14:30 local time, the pilot was conducting a visual flight rules (VFR) private flight and was landing on runway 24 at Flugplatz Lommis (LSZT). During the landing roll, the aircraft decelerated abruptly and subsequently nosed over. The investigation determined that the skis on the main landing gear were extended at the time of landing, which caused the sudden braking and the subsequent overturn.
Damage and Injuries
The aircraft sustained damage to its wings, tail empennage, propeller, and the skis. The pilot and the sole passenger were not injured. There was no third-party damage.
Investigation
The Swiss Transportation Safety Investigation Board (SUST) conducted a summary investigation in accordance with Articles 45 and 46 of the Ordinance on the Safety Investigation of Transport Incidents. The investigation concluded with this summary report.
