Narrative:The DC-3 took off from the island of Texel at 16:28 for a return trip to Amsterdam. Engine problems were reported at 16:33 to Texel Radio. The crew switched over to NAS De Kooy Approach and told De Kooy they wanted to make an emergency landing. At that time they were flying at 600 feet, 11nm NE of NAS De Kooy. The crew tried to feather the no. 1 prop, but part of the feathering-mechanism failed. The prop started windmilling, causing drag.
The aircraft descended and control was lost at 180 m when the speed had dropped below minimum control speed. The DC-3 crashed onto a mud-flat.
The aircraft had been overloaded by 240 kg (maximum 11895 kg), but this wouldn't have had any negative effects on the controllability of the aircraft.
Probable Cause:
PROBABLE CAUSES: "The accident was initiated by a combined failure of the left engine and the left feathering system. The accident became inevitable when the flight crew allowed the speed to decrease below stall speed and lost control of the aircraft at an altitude from which recovery was not possible.
Contributing Factors were: 1) serious degradation of controllability and performance.; 2) a high work load imposed on the flight crew by the multiple failure, further increased by unfavorable flight conditions and a suboptimal cockpit lay-out.; 3) the inadequate level of skill and experience of the flight crew on the DC-3 to be able to cope with this specific emergency situation."

Follow-up / safety actions
RvdL issued 5 Safety Recommendations
Issued: 11-DEC-1997 | To: CAA Netherlands | PH-DDA (1) |
Disseminate information how to feather a propeller in case of malfunctioning of the feathering system. |
Issued: 11-DEC-1997 | To: CAA Netherlands | PH-DDA (2) |
For operations with historical aircraft requirements such as mentioned in the "Nota Historische Luchtvaart" should be implemented. |
Issued: 11-DEC-1997 | To: CAA Netherlands | PH-DDA (3) |
For transportation of passengers in historical aircraft the flight crew proficiency should be on the level of JAR-OPS, Chapter "N" whereby the level of skill and experience of flight crew should be further enhanced by providing more hands-on flight exposure. |
Issued: 11-DEC-1997 | To: CAA Netherlands | PH-DDA (4) |
Investigate the necessity and the possibilities of using a simulator with flight characteristics comparable to a DC-3 in order to increase the skill of flight crew. |
Issued: 11-DEC-1997 | To: CAA Netherlands | PH-DDA (5) |
Passengers must be fully and timely informed about the lower safety level when travelling in historical aircraft. |
