What happened
On the afternoon of 29 March 1995, a scheduled flight departed from Hamilton, bound for New Plymouth. Shortly after takeoff, the aircraft, a ZK-TIK, experienced a rapid loss of power as both engines failed in quick succession. At a low altitude, the aircraft entered a stall and subsequently entered a spin. The accident resulted in six fatalities.
The investigation
The investigation into the crash focused on the sequence of engine failures and the subsequent flight path of the aircraft. Investigators examined the fuel systems and the actions taken by the crew following the loss of power. The inquiry established that the dual engine failure was triggered by a specific error in the fuel system configuration during the flight.
Findings
The primary cause of the accident was a mis-selection of a fuel tank, which led to the simultaneous failure of both engines. Additionally, the crew failed to execute an appropriate forced landing procedure once the engines lost power. The investigation also identified a contributing factor in the aircraft's fuel management system, noting that the existing regime was designed in a way that allowed for potential mismanagement.
Safety action
As a result of the findings, the investigation highlighted the need for improved checks and clearer communications during emergency situations. Four specific safety recommendations were issued to the Civil Aviation Authority, focusing on the necessity of enhanced pilot education regarding fuel management and emergency procedures.
