Piper PA-34 Nose Gear Collapse at Wonderboom Aerodrome (ZS-JOC)

Incident Overview and Aircraft Details On 7 June 2005, a Piper PA-34 with registration ZS-JOC was involved in an accident at Wonderboom Aerodrome (FAWB) in South Africa. The aircraft was operating a training flight with an instructor, a student, and a passenger on board. The pilot-in-command held a commercial license and had 12,333 total flying hours, including 480 hours on the specific aircraft type. The flight departed from Wonderboom Aerodrome at 0940Z and was intended to return to the same location after approximately 1.5 hours in the general flying area. ## Accident Sequence and Meteorological Conditions During the return to FAWB, the crew planned to conduct several circuits and landings. On the first landing, the aircraft touched down normally on both main landing gears. However, the nose gear collapsed upon touchdown. The instructor confirmed that three green light indications showed the landing gear was down and locked. As the aircraft slowed, the pilot turned left to clear the runway and avoid blocking it. Meteorological conditions at the time were CAVOK with calm surface winds, a temperature of 23°C, and a QNH of 1023. The accident site was located on runway 29 next to the intersection of runway 24. ## Investigation Findings and Probable Cause The owner's questionnaire indicated that the nose gear collapse was due to mechanical failure, though the specific component that failed was not identified. The last mandatory periodical inspection was completed on 17 January 2005 at 3,634.14 flying hours, with the aircraft operating for an additional 66.84 hours before the accident. The aviation training organization (ATO no. CAA/0263) had its last audit on 4 May 2004, with approval valid until 12 June 2005. No injuries or fatalities were reported. The investigation concluded that the nose gear collapsed, but the specific cause of the failure was not determined.
