What happened
On 22 November 2017, a private flight departed from Cape Town International Airport (FACT) destined for Rand Airport (FAGM). The flight was operated under instrument flight rules (IFR) during the departure and transit, while the final approach was performed under visual flight rules (VFR). The crew consisted of a pilot-in-command and a first officer.
Upon approaching Rand Airport, the crew received wind information for Runway 29 indicating a direction of 230 degrees at 11 knots, with a QNH of 1021. The crew opted to land on Runway 11. During the landing sequence, the aircraft experienced a period of floating before making contact with the runway near the first taxiway exit.
As the aircraft continued its rollout, the pilot-in-command attempted to use the brakes, which initially functioned but then failed to decelerate the aircraft. After traveling roughly 300 metres past the intersection of Runway 35 and Runway 11, the pilot requested that the first officer engage the emergency brakes. The application of the emergency brakes caused the tires to burst and lock. The aircraft subsequently skidded on its main wheels for an additional 180 metres, eventually overshooting the runway. The landing gear struck a 200-millimetre deep ditch at the runway end, leading the aircraft into soft ground. The aircraft stopped approximately 10 metres from the threshold of Runway 11, positioned slightly left of the centerline. The aircraft sustained substantial damage, but there were zero injuries among the occupants.
Findings
Investigation into the incident confirmed that the aircraft experienced a failure of the primary braking system during the landing rollout, which prevented the crew from slowing the aircraft sufficiently to remain on the runway.
