Description
Viking G-AHPD took off from Bordeaux at 14:10 UTC for a flight to Bovingdon. Climbing through 50 m, the pilot throttled down to initial climbing speed. The no. 1 engine then suddenly began to lose power. This engine was shut down, propeller feathered and full power applied to the remaining no. 2 engine. Altitude could not be maintained, causing the crew to decide upon a belly landing. The aircraft slid for about 100 m before coming to rest. PROBABLE CAUSE: “The disconnecting of the articulated control rod of the propeller governor due to the lack of a split pin on the governor spindle and to the nut of the ball-joint of the control spindle having been unscrewed by force.”

Disconnecting of the articulated control rod of the propeller governor due to a lack of a split pin on the governor spindle and to the nut of the ball-joint of the control spindle having been unscrewed by force.Disconnecting of the articulated control rod of the propeller governor due to a lack of a split pin on the governor spindle and to the nut of the ball-joint of the control spindle having been unscrewed by force.Share on:
