The flight
editThe flight was being operated by Lockheed L-049 Constellation NC86505, c/n 2026, named Cairo Skychief. On approach to Shannon airport the aircraft struck the ground on Inishmacnaughton and was destroyed by fire, having broken up on impact.[1] Of the 23 people on board, nine died; four crew members and five passengers,[2] however, a 1947 amendment to the CAB report states that nine passengers died.[3]
This TWA flight was authorised to carry persons, property and mail between the cities of the route.[3] It was reported in The Times that this was a mail carrying flight and that the mails were retrieved but, as of 1997, no covers have been noted.[1]
The accident
editCairo Skychief departed Paris-Orly at 23:16 arriving at Shannon at 02:00 when Shannon control tower cleared the aircraft for approach to runway 14. At 02:06 the crew reported being over the range station at 1,200 ft (370 m). Shannon Tower advised the crew that Shannon was reporting 10/10 cloud cover at 400 ft (120 m), 4/10 at 250 ft (76 m), visibility 1 mi (1.6 km), wind 120 degrees, 5 kn (9.3 km/h; 5.8 mph). During the left turn onto final, the aircraft passed behind a low hill blocking the airport lights from the pilot's vision, the aircraft lost altitude and the port wing-tip struck the ground; the aircraft crashed and caught fire.[2]
Captain Herbert W. Tansey and First Officer Clifford V. Sparrow were seriously injured, but were among the survivors.[3][4] The Irish Department of Industry and Commerce, the U.S. Civil Aeronautics Administration, and the TWA Regional Accident Board started an investigation into the crash.[4] Investigators arrived in Shannon on 31 December for the local phase and later phases took place in London, New York, and Wilmington, with a public hearing on 30 and 31 January 1947, in New York City.[3]
Causes
editContributory causes were determined to have been the incorrect assembly of the instruments static pipelines and the poor weather conditions.[2]
