What happened
On 11 November 2003, a PIPER PA-28-140, registered ZS-JLF, was conducting a solo training flight departing from George Aerodrome. After operating within the General Flying area near Mossel Bay, the student pilot returned to the aerodrome for landing on Runway 29. The weather conditions were clear with good visibility.
As the aircraft approached the runway, the pilot encountered a slight crosswind, necessitating a left crab. The pilot reported applying the necessary rudder input to correct the heading just before touchdown. While the main wheels made contact with the runway first, the subsequent touchdown of the nose wheel was followed by a mechanical failure of the nose wheel assembly. This failure caused the propeller to strike the runway surface. The pilot attempted to maintain the aircraft's heading, but the loss of control caused the plane to veer left off the runway, eventually coming to a rest in a nose-down position. The pilot escaped the wreckage without injury.
The investigation
Investigators examined the circumstances surrounding the landing and the mechanical state of the aircraft. The aircraft had undergone its last Mandatory Periodic Inspection (MPI) on 5 November 2003, with 28 flight hours accumulated since that inspection. The investigation confirmed that the student pilot held a valid license and the flying school maintained proper accreditation.
However, the physical evidence regarding the mechanical failure was limited. Because the nose wheel fork skidded along the runway surface during the incident, the resulting impact damage prevented a metallurgical examination of the component. Consequently, the specific origin of the structural failure could not be identified.
