Détails:
Bristol 170 Freighter 21 had just been converted from Mk. 2A to Mk. 21 and was on its second test flight for the Certificate of Airworthiness renewal. Some 34 minutes past departure the aircraft entered a spin, crashing out of control.

Probable Cause:

PROBABLE CAUSE: "The accident is a result of a structural failure of the fuselage stern frame to which the fin is attached and must be attributed to the application on the fin and rudder of a load greater than the design ultimate load. Calculations suggest that the cause of this overloading was excessive rudder movement at a speed greater than 120 knots EAS."
