AAIB investigation to Piper PA-22-108, G-ARNE
Partial aileron detachment with non-standard part fitted, Old Buckenham Airfield, Norfolk, 23 May 2025
During the initial climb after takeoff, the left outboard aileron hinge detached. The pilot was able to maintain control and land without incident. Assessment of the aircraft revealed that a non-standard clevis pin had been fitted to the right outboard aileron hinge. It is possible that a similar non-standard part had been fitted to the left aileron and had failed, or fallen out during operation.
This event serves as a reminder to ensure that when maintaining aircraft the correct parts are used.
