Incident
On 7 August 1969, a Rhönlerche-II glider, registered as HB-623, was involved in an accident while attempting to land at the Fricktal-Schupfart airfield in Switzerland. During the final approach, the glider descended too low and collided with a tree. The pilot remained uninjured, but the aircraft suffered severe damage.
Investigation
The Swiss Federal Aircraft Accident Investigation Commission investigated the occurrence. The investigation concluded that the approach was conducted with unsuitable flight tactics, causing the glider to fly at an insufficient altitude. This resulted in the collision with the tree. The commission's final report, dated 12 November 1969, was approved by circular decision on 26 February 1970.
Probable Cause
The approach for landing was too low due to unsuitable flight tactics, leading to a collision with a tree.
