The pilot and passenger departed from Paraparaumu in ZK-FTO for a flight to Nelson and return. The pilot reported to Nelson Tower crossing through French Pass. No further communications were received. The aircraft was seen and heard by residents of D'Urville Island flying in low cloud and reduced visibility. The sound of an impact prompted a ground search but due to the poor weather the wreckage of ZK-FTO was not located until the following morning. Neither occupant had survived the impact and ensuing intense fire.
