Crashed due to engine failure. According to a rough translation (from French into English) of the official AAIB accident report:
"After two touch and go landings on Runway 34, two hundred feet in the initial climb, the engine undergoes a series of regime changes accompanied by vibrations. The instructor takes orders, passes bearing and makes a low height right hand approach to runway 34. The instructor announces engine problems to the Air Traffic Controller that gives priority to land. The instructor landed and joined the parking retaining the use of the engine.
On the ground, the cylinder #2 is found detached from the casing, three fixing studs at of the base of cylinder are broken. The exhaust pipe is severed at the fixing the cylinder.
The engine underwent a tour of fifty hours on 4 April 2002. The program of this tour includes a visual check of the bases of the cylinders in accordance with the Airworthiness. The engine had worked eight hours from this visit and 602 hours since overhaul. Examination of the fracture surfaces of the two studs found broken ends exhibit cracking zones fatigue (indicating a break in cracking progressive under cyclic loading) without any type of corrosion defect or inclusion has been highlighted.
The damage observed on one of the studs appraised indicate that it has suffered abnormal bending efforts. However these can be the result both a lack of clamping, only the earlier breakdown of other unrecovered studs."
