The Air Moorea DHC-6-300 Twin Otter turboprop that crashed near Moorea Island on Aug. 9, 2007, took off with an almost failed pitch-control cable, due to recent exposure to jet blast, according to French Bureau d’Enquêtes et d’Analyses (BEA) chief Paul-Louis Arslanian. Other causes include the omission of cable inspections and the use of stainless-steel cables, which are more prone to wear.
