What happened
On 22 January 2017, a Cessna U206G, registration ZS-ANA, was preparing for a private VFR flight between two lodges in the Limpopo Province. The flight was intended to proceed from Shikwaru Lodge to NB Safaris Lodge. During the takeoff roll from the grass runway, the pilot observed that the aircraft was accelerating sluggishly and failing to reach the necessary airspeed for lift-off.
In response to the lack of acceleration, the pilot attempted to abort the takeoff by reducing power and applying maximum braking. However, due to the runway surface being wet and slippery from recent rainfall, the aircraft could not be brought to a halt. The aircraft began to slide, veered off the end of the runway, and eventually struck a bamboo fence. There were no injuries to the pilot or the passenger.
The investigation
SACAA AIID investigators examined the circumstances surrounding the excursion and confirmed that the pilot held a valid Private Pilot Licence and a Class 2 medical certificate. The aircraft was found to be airworthy, with no pre-existing defects noted, and the aircraft mass was within established limits. The investigation also confirmed that the aircraft carried sufficient fuel for the intended mission.
Findings
- The primary cause of the incident was an unsuccessful aborted takeoff caused by the aircraft's inability to reach takeoff speed.
- The wet grass runway surface significantly contributed to the accident, as the lack of friction prevented the brakes from effectively stopping the aircraft.
- The aircraft sustained minor structural damage from the impact with the fence.
