Hiway Demon 195 (Modified) G-MMYW: Written off (damaged beyond repair) 12/10/1986 when wrecked in a heavy landing at Butterton, 5 miles East of Leek, Staffordshire; the pilot (the sole person on board) sustained moderate injuries. According to the following extract from the official AAIB report into the accident:
"After conduction several trial taxi runs, the aircraft became airborne on what is believed to have been the first flight of this microlight, and possibly the first flight of the pilot in command. After climbing to approximately 30 feet, the microlight was seen to turn through 180 degrees, descend, and collide with a small tree, and then land heavily on its landing gear. The pilot sustained moderate injuries to his back and lungs."
Subsequent post-crash investigations revealed that the microlight was poorly constructed, using unapproved materials and construction methods, and had not applied for a permit to fly or a certificate of airworthiness. In addition, the original engine fitted/supplied (a Fuji Robin 440cc engine) had been replaced by an engine (apparently) from a motor cycle. The aircraft had been so much modified from the original, that the AAIB report describes G-MMYW as a "homebuilt, based on a Hiway Demon".
The pilot in command did not have a pilots licence or log book; moreover, there was no evidence that the pilot in command any flying experience or training whatsoever. Hence the reference above to the flight being unauthorized, perhaps even "illegal"; the aircraft was probably not airworthy, and the pilot had no authority to fly it!
Damage sustained to airframe: Per the AAIB report: "Damage to both trike and wing was consistent with a heavy landing, indicated by an overload failure of the left main landing gear. There was also damage to the nose wheel, failure of the seat fabric at its attachment to the seat frame, and general distortion to the trike frame. The propeller was also been shattered by one of the flying wires, at a point 10 inches inboard from the tip".
Although the aircraft was sold on to a new owner on 6/4/1987, the registration G-MMYW was cancelled by the CAA on 13/6/1988 just under two years after its accident.
Butterton is a small village in the Staffordshire Peak District of England. It overlooks the Manifold Valley and Ecton Hill, which rises 1,212 feet above sea level. Butterton lies 5 miles east of Leek
