Factual Information
The Swedish Accident Investigation Authority (SHK) investigated an accident involving a Diamond HK36 TS motor glider, registration SE-UVN, at Othem airfield on Gotland on 4 June 2024. The flight was a proficiency check for extension of the TMG class rating.
Accident Sequence
During a landing exercise, control of the aircraft was lost. The aircraft veered into high grass and sustained significant damage. No persons were injured.
Aircraft and Injuries
The aircraft, a Diamond HK36 TS, suffered significant damage. There were no reported injuries to any persons.
Cause of the Accident
The SHK determined that the accident was caused by inadequate preparations for the flight, which lacked a clear plan for handing over control of the aircraft. This, combined with a go-around with insufficient altitude margins and the airbrakes possibly remaining in the deployed position, led to the aircraft unintentionally touching down. The unsuitable nature of the field contributed to the outcome of the accident.
