| Confidence Rating: |  Accident investigation report completed and information captured |
The aircraft was on a solo local flight and while flying over the sea at about 1,500 feet it suddenly went into a near vertical spiralling dive. This terminated with the aircraft becoming inverted at which time, the outer section of the left wing broke off, after which the aircraft disintegrated and fell into the sea. The pilot was killed.
The report concludes that the aircraft broke up in flight, the accident sequence being initiated by the failure of the fin front attachment. This precipitated an involuntary manoeuvre in which the aircraft was subjected to a negative 'g' loading in excess of its design ultimate limit resulting in a total in-flight structural break-up. The most probable cause of the failure of the fin front attachment was movement in the tail unit as a result of looseness and wear of the two elevator centre hinge bracket bolts and elongation of their associated holes.
Registration G-ASHF cancelled by the CAA 1/12/75 as aircraft "destroyed"
