Narrative:
Force landed at Gayton, at approximate co ordinates 52'42" North, 00;28" East).

The accident occurred during a scheduled passenger flight from Birmingham to Norwich, with a pilot and seven passengers aboard, when a propeller blade detached from the right engine propeller assembly, and passed through the aircraft's nose baggage bay, before damaging the left engine propeller, and stopping the left hand engine

As a result of the ensuing severe out-of-balance forces on the right engine, the right engine separated from the airframe almost immediately. The aircraft rolled to the right, and entered a tight spiral dive, spinning towards the ground.

However, the pilot managed to regain control of the aircraft, and carried out a successful forced landing. Both the pilot and his seven passengers were uninjured, apart from one passenger, who later complained of neck pains.

The RH propeller hub had failed as a grease hole that had not been masked during shot-peening, leading to a blade loss. This resulted to the RH engine tearing off and debris damaging the LH propeller.

AAIB made 4 recommendations.

The aircraft was repaired/rebuilt, and added to the US registry as N189SA on 17-11-2000
