Confidence Rating:
Rotorsport UK Cavalon, G-CKYV was written off (damaged beyond repair) due to an uncontrolled pitch up and left roll during takeoff, Wolverhampton Halfpenny Green Airport, Bobington, Staffordshire, 9 August 2018. The official AAIB report was published on 10 January 2019, and the following is an excerpt from it:

"The pilot was delivering the aircraft to a new owner. As is usual, he engaged the pre rotator before departure to accelerate the rotor to a suitable rpm for takeoff, and he recalled seeing 200 rpm, which was normal. Shortly thereafter, he noticed that the rotor indication had dropped to zero and, concerned that the rotors might now be rotating at less than 200 rpm, decided to attempt to increase the rotor rpm by commencing a takeoff roll with less than full power.

At approximately 30 knots, the cyclic control moved violently and was wrenched from his grasp. The aircraft pitched up, yawed left and rolled left before falling upright and sliding along the runway. The pilot was assisted from the aircraft by the Fire Service and suffered only minor injuries."

Damage sustained to airframe: Per the above AAIB accident report G-CKYV was "Damaged beyond economic repair"
