AAIB investigation to Jabiru UL-450, G-CBGR
Uncommanded flap retraction at 40 ft agl, Clench Common Airfield, Marlborough, Wiltshire, 1 February 2022.
Summary:
In the final stages of the approach to landing, the flaps retracted uncommanded by the pilot, who was subsequently unable to prevent the aircraft striking the ground heavily. Both the pilot and passenger were injured, and the aircraft was severely damaged.
The flap handle pivot bolt had become detached from its gate during the approach, allowing the flap handle to move and the flaps to retract.
