KLM Flight 607-E, flown by Lockheed Super Constellation named Hugo de Groot and registered PH-LKM,[1] was an international scheduled flight that crashed 180 kilometres (110 mi) west of Shannon, Ireland on 14 August 1958. All ninety-one passengers and eight crew died in the accident, including six members of the Egyptian fencing team (Osman Abdel Hafeez, Mohamed Ali Riad, Ahmed Sabry, etc.).[2] The "E" in the flight number stood for the designation of being an extra economy class flight to match the increased seasonal tourist demand.[3]
Flight 607-E departed Shannon at 3:05 UTC on the second leg of a transatlantic trip from Amsterdam to New York City with intermediate stops in Shannon and Gander, Newfoundland. Radio contact with the aircraft was lost at approximately 3:40 UTC; a rescue operation was launched which found light debris on the surface of the ocean approximately 180 km west of Shannon. The remains of thirty-four of those on board were also recovered.
Due to the lack of evidence, Irish and Dutch investigators could not pinpoint a probable cause for the accident. They examined the possibility of a bomb, electrical failure or pilot error, but believed that the most likely possibility was a catastrophic mechanical failure. The cause of the accident is believed to be a malfunctioning overspeeding outboard propeller caused by metal particles obstructing oil feed line regulator valves. The particles may have been formed by a gear that was damaged when the supercharger of the corresponding engine was accelerated (gear ratio shifted). The malfunctions of the propeller pitch might have provoked a flight disturbance and as a consequence the propeller may have sheared off.
