What happened
On 4 May 2001, a Cessna C188, registration ZS-KOD, was engaged in agricultural crop spraying operations in the Heatonville district. While flying between two private farms, the aircraft encountered significant engine issues. In an attempt to perform a forced landing, the pilot struck two power lines, which were severed during the impact. The aircraft was destroyed by the forces of the crash. While there were no fatalities, the pilot sustained serious injuries.
During the impact, the pilot's safety harness failed, causing the pilot to be ejected from the cockpit and end up underneath the wreckage. Local bystanders were required to physically lift the aircraft to rescue the trapped pilot.
The investigation
SACAA AIID investigators examined the mechanical state of the aircraft and the regulatory compliance of the operator. The investigation established that the aircraft was not in an airworthy condition at the time of the accident. Specifically, the aircraft's mandatory Periodic Inspection (MPI) had been exceeded by 295.09 hours. Additionally, the registered owner was found to be operating without the required Operator's Licence as mandated by the Domestic Air Services Licence Act.
Weather conditions at the time of the incident were reported as fine by both the pilot and witnesses. While the propeller was considered serviceable prior to the event, the engine failure was the primary driver of the accident.
Findings
- The aircraft was flying with an overdue maintenance inspection.
- The operator lacked the necessary legal authorization to conduct air services.
- The failure of the safety harness contributed to the pilot's severe injuries and ejection from the cabin.
- The engine failure was likely caused by fuel contamination resulting from inadequate maintenance protocols.
