Investigating agency: AAIB
Following a period of maintenance during which the aircraft fabric covering had been replaced, the pilot was carrying out a ground run and taxi test. During taxi the pilot heard a rattle and decided to try to identify its source and so taxied the aircraft at higher speed.

To his surprise, the aircraft became airborne but right wing low. Despite his attempts, he could not prevent the aircraft from flying a continuous turn to the right. The aircraft hit a tree and then struck the ground, still right wing low, before ‘pole vaulting’ over a dry-stone wall. The aircraft came to rest approximately where it had started the taxi.
The pilot suffered serious injuries but has since recovered.

AAIB Conclusion:
During a high-speed taxi run, the aircraft became airborne unintentionally and, thereafter, became established in a continuous right turn which could not be controlled by the pilot.
This was due to an increase in the lift produced by the left wing which was greater than could be countered by the roll spoiler. The increased lift was likely to have been the result of a slight change in the shape of the mid to outer section of the left wing caused by overly tight flying wires.
