At approximately 1420 hours on Sunday 24 September 1995, ZK-FPM was mid-downwind for a landing at the Chateau Airstrip near Mt Ruapehu when the engine suddenly lost power. The pilot changed the fuel tank selection and power was restored but on final approach the engine lost power again. Two of the five occupants received back injuries in the ensuing forced landing on undulating ground short of the airstrip. The cause of the initial power loss was not determined.
