A single-engine plane had to make an emergency landing in Triengen on Friday due to a technical problem.
Four people were on board, all of whom were uninjured.
The STSB and the Office of the Attorney General of Switzerland are jointly investigating the incident.
An emergency landing was made at Triengen airfield on Friday afternoon. Shortly before 12.15 p.m., a single-engine aircraft unexpectedly landed after a technical problem was suspected on board. Four people were in the cockpit and on the passenger seats, but no one was injured.
The emergency services from the Triengen regional fire department, the Sursee region fire department, the rescue service and a rescue helicopter were quickly on the scene. After landing safely, the aircraft was secured and the occupants were medically assessed.
