|Fatalities:||Fatalities: 0 / Occupants: 5|
|Aircraft damage:|| Substantial|
|Location:||near Rangiora Airfield, Canterbury -
|Phase:|| Initial climb|
|Departure airport:||Rangiora Airport (NZRT)|
|Confidence Rating:|| Information verified through data from accident investigation authorities|
Due to an attempt to avoid trees, one wing struck the ground and the aircraft landed heavily. One of the occupants suffered a minor injury and there was significant damage to the aircraft.
The aircraft had an engine monitoring system installed, the data from which revealed a drop off in the #6 cylinder temperature. The engine was stripped and the #6 cylinder inlet valve was found to have an irregular wear pattern in the tip face and localised heating associated with a valve not rotating as it should. This can lead to a stuck valve. No conclusive reason could be determined for the anomaly. The cylinder had completed approximately 400 hours time since new.
