A Blenheim pilot who died while attempting a prestigious 1000km glider flight encountered significant turbulence before the aircraft crashed nose-first into a ridge, an investigation has found.
Experienced glider pilot Mike Dekker, 55, was killed when his glider crashed into Orchard Spur, about 14km south of Blenheim, on December 18, 2009.
A Civil Aviation Authority (CAA) report, released today, said its investigation could not determine the cause of the crash for certain, but there was no indication that mechanical failure had contributed.
Mr Dekker, who had almost 2000 hours gliding experience, had been on his 12th attempt to qualify for a 1000km gliding badge and diploma - an achievement the CAA said would have earned him prestige and respect among his peers.
He was the national operations officer for Gliding New Zealand and was a senior member of the local gliding club.
