'Cardiac event' cause of aircraft crash.

A man who died after crashing his aircraft at Tauranga airport suffered a "cardiac event", a report into his death has revealed.

A coroners report, released today, said Jeffrey Arthur Bryant, 56, died as a result of multiple injuries sustained in a microlight aircraft crash on September 27, 2010.

The report revealed Mr Bryant was completing a "touch and go'' manoeuvre, where the pilot lands the plane but while taxiing on the runway, power is increased and the plane takes off again.

Mr Bryant had completed this once and the crash happened at the conclusion of the second.

Coroner Tim Scott said after the completed second "touch and go" landing, the aircraft began climbing at a steep angle.

"It then began a steep left-hand descending turn. It recovered briefly from the descent and began to climb again but then entered into another steep left descending turn from which it did not recover but rather struck the ground," he said.

"It appears that the aircraft climbed to about 200 feet before entering into the left-hand descents."

Mr Scott said he crash occurred because Mr Bryant, the pilot, suffered an "incapacitating medical event - probably a cardiac arrest - which rendered him incapable of controlling the aircraft''.

Mr Bryant suffered major injuries in the crash and died at Tauranga Airport, about 8.30am.

Mr Bryant was a self- employed rural contractor and lived in Pio Pio, in the King Country.
