What happened
On 4 September 2021, a Motor Falke SF25C, registration ZS-GYH, was performing circuit landings at Orient Airfield (FAOI) in Gauteng. The flight, a private operation, was being conducted under clear visual meteorological conditions. After successfully completing an initial touch-and-go landing, the pilot attempted a second circuit on Runway 36L.
During the final descent, the pilot experienced a distraction caused by an unusual sensation in the coordinated spoiler control. This distraction led to a loss of airspeed, with speeds dropping to between 90 km/ and 100 km/h. Consequently, the aircraft was at an excessive height during the final approach. The pilot subsequently initiated a flare at too high an altitude and potentially applied excessive airbrake. This sequence caused the aircraft to stall during the landing phase, resulting in a hard landing.
The investigation
The investigation examined the flight parameters and the physical state of the aircraft following the impact. It was noted that while the pilot felt the distraction during the approach, a go-around was not attempted. Post-accident inspections by an approved person confirmed that the engine flange remained undamaged. However, the impact caused significant structural and component damage.
Findings
- The aircraft was approaching the runway at a higher altitude than was ideal for the landing configuration.
- The pilot's attention was momentarily diverted by the sensation of the spoiler controls.
- The application of excessive airbrake and an improper flare height led to a loss of airspeed and a subsequent stall.
- The hard landing caused the propeller to strike the ground and resulted in the bending of the airframe tubing behind the monowheel.
- There were 0 fatalities and 0 injuries to the two occupants on board.
