Narrative:
Mudry Cap 231 G-IIHZ: Substantially damaged 9.1.2022 sustained structural damage over Mundesley, 7 miles South East of Cromer, Norfolk. The rudder cable attachment failed in flight. The aircraft landed safely.

The pilot had taken off from Northrepps Airfield in Norfolk to carry out an aerobatic display sequence practice towards the North Norfolk coast. The pilot had completed several high energy manoeuvres, and as he neared the end of the display sequence and was conducting a vertical left roll, he felt a “jolt” through the aircraft, which immediately departed into an inverted spin.

He closed the throttle and realising that there was something odd about the yaw control, he gently recovered the aircraft to level flight using the ailerons. He was able to retain control of the aircraft and carried out an extended long final approach to land back at the airfield. The landing was uneventful.

Examination of the aircraft immediately after the flight found that the rudder control horn had partially broken away from the rudder structure on its left side. There was also dis-bonding damage towards the bottom of the fin ‘stern post’. The small aluminium alloy fairing which forms the leading edge at the bottom of the rudder was also trapped and deformed."

=Nature of Damage to airframe=:
Per the above AAIB Report: "Control arm mount detached from rudder, fin stern post dis-bonded from fin structure"
