What happened
On 9 October 2022, a Jabiru J1 70 with registration ZU-IBE departed Wonderboom Aerodrome for Kitty Hawk Aerodrome in Gauteng Province. The flight, conducted under private operations, was uneventful until the arrival phase. While performing a right-hand circuit, the pilot noted a crosswind and adjusted the approach accordingly.
During the final approach, the aircraft was traveling at approximately 65 knots. The pilot touched down roughly 150 meters past the runway threshold. Although there was sufficient runway remaining to stop, the pilot observed that the aircraft was not decelerating adequately as it passed the clubhouse. In an attempt to increase braking effectiveness, the pilot steered the aircraft onto the grass adjacent to the runway, turning right to avoid nearby trees. Upon contacting the grass surface, the nose landing gear failed, resulting in substantial damage to the aircraft. Both the pilot and the passenger exited the aircraft without injury.
The investigation
The SACAA AIID examined the flight parameters, weather conditions, and aircraft maintenance records. The investigation confirmed that the pilot held a valid Private Pilot Licence and that the aircraft's most recent mandatory periodic inspection was current. The investigation also reviewed the wind conditions, noting a crosswind of approximately 5 knots, which was well within the aircraft's operational limits.
Findings
- The pilot performed a deep landing, touching down 150 meters beyond the runway threshold.
- The pilot steered the aircraft onto the grass area in an attempt to decelerate, which caused the nose gear to break off.
- The aircraft was noted to be unstable during the approach phase.
- The landing speed of 65 knots was consistent with the manufacturer's recommended best glide speed.
- The prevailing wind conditions were within the allowable crosswind limits for the aircraft type.
