The pilot had been authorised to carry out circuit and landing practice. He had been operating for about 20 minutes when witnesses observed that immediately after lift-off from a touch and go landing, the aircraft assumed a higher than normal nose attitude. At an height of between 100 and 150 feet above the runway, the engine noise ceased and the aircraft pitched forward to a steep nose down attitude. This attitude was maintained until the aircraft impacted the ground, before coming to rest 50 metres to the right of the runway centreline. A subsequent investigation determined that the pilot had probably suffered a heart attack at about the point of lift-off, resulting in incapacitation and loss of aircraft control.
