air accident investigators have established that a fractured elevator cable was
the direct cause of last August’s fatal Air Moorea de Havilland Canada
Twin Otter crash in French Polynesia,
confirming earlier indications.
9 August 2007 the Air Moorea aircraft suffered a
sudden and rapid loss of control, causing it to crash into the sea just 11s
later claiming the lives of all on board - the pilot and 19 passengers.
December investigators from France’s
Bureau d’Enquetes et d’Analyses (BEA) said they were focussing their attention
on a fractured elevator cable which was discovered in the wreckage of the Twin
its preliminary findings BEA said that recovery personnel had retrieved the
entire pitch-down cable from the sunken wreckage. But an 8.8m (29ft) section of
the pitch-up cable, between its forward and rear fracture points, was missing.
the time BEA had only concluded the initial stage of its probe and it had not
formally linked the damage to the accident.
today’s update, the BEA says: “A preliminary report, published on 6 December
2007, established that the elevator control cables showed significant worn
studies have confirmed that the failure of the elevator pitch-up cable, at the
moment when the flaps were retracted, was the direct cause of the accident.
Tests and research have made it possible to reconstruct the complex process
which led to the failure of the cable.”
adds that the full report will be published before year-end.
