What happened
During a routine topdressing operation, an aircraft experienced a critical loss of power following its departure from Tiraumea, located approximately 47 km northeast of Masterton. Shortly after the takeoff phase, the engine failed, leading to an aerodynamic stall. The subsequent impact resulted in the total destruction of the airframe.
Despite the severity of the crash, no injuries were reported for the pilot on board. The aircraft was subsequently declared a write-off.
Findings
Investigations into the accident determined that the engine failure was triggered by the use of improper fuel. Specifically, the engine was supplied with non-compliant 87 octane fuel, which led to the mechanical failure during flight.
