AAIB investigation to CAP 231, G-IIHZ
Rudder and fin structural failure in flight, Northrepps Airfield, Norfolk, 9 January 2022.
Summary:
The pilot had taken off from Northrepps Airfield in Norfolk to carry out an aerobatic display sequence practice. During one of the manoeuvres, he felt a “jolt” through the airframe and the aircraft departed into an inverted spin. He was able to regain control of the aircraft and land back on the airfield. Examination of the aircraft found that the plywood mounting structures of the lower hinge assembly of the rudder and fin had failed. The exact cause and sequence of the failure of the various structures could not be determined.
