Narrative:
While attempting to land at Tiraora Lodge the pilot was dazzled by low sun and elected to overshoot. The aircraft made a low turn to avoid high ground, struck a telephone wire and descended out of control into the sea.

Probable Cause:

CONCLUSION: The probable cause of this accident was the pilotís decision to continue to fly the aircraft, at 200 feet amsl, past the point from which a missed approach could be successfully achieved, when he was unable to see the position of the runway, its threshold or the windsock.

Other contributory factors were:
The pilotís unfamiliarity with the Tiraora Lodge Airstrip,
The pilotís inadequate training in strip operation and on the aircraft type
The pilotís failure to check the position of the aircraftís flaps, visually, during the missed approach procedure when he believed the flap position indicator to be unreliable,
The pilotís unfamiliarity with the aircraftís flap operating system,
The lack of a suitable wind measuring device or other information on
the local winds in the area and the presence of a substantial downflow in the area of the attempted missed approach,
Obstructions within the obstruction free area prescribed for approved landing grounds, and
The absence of supervision of the airline by the regulatory authority.
