What happened
On 8 February 2002, a Volksplane VPII, registered as ZS-WXZ, departed from Wolmaransstad aerodrome for a private flight. The aircraft was carrying a pilot and one passenger. During the initial climb phase, immediately following rotation, the engine began to lose power. To avoid a more serious impact, the pilot executed a forced landing in a cornfield located approximately 100 meters outside the airport perimeter. Despite the emergency, there were no fatalities or injuries resulting from the incident. Weather conditions at the time were clear with light northerly winds and partial cloud cover.
The investigation
Investigators examined the aircraft's maintenance history and physical condition following the event. While the pilot held a valid license and medical certificate, the investigation revealed that the aircraft had not been issued an official Authority to Fly, though it was operating under a valid Special Flight Permit.
Upon inspecting the aircraft at the site, investigators found that the cockpit was not fitted with any seats. Furthermore, although the aircraft had undergone an annual inspection in April 2001, the overall condition of the airframe did not meet standard general aviation requirements. The investigation also scrutinized the inspection process, noting that the person responsible for certifying the annual inspection failed to utilize an approved checklist.
Findings
- The aircraft possessed sufficient fuel for the intended flight.
- An obstruction within the fuel tank was identified, which prevented the necessary flow of fuel to the engine.
- The inspection checklist used during the previous annual maintenance was inadequate, as it failed to include a specific check for foreign matter or obstructions within the fuel tank.
- The maintenance professional did not adhere to approved inspection protocols.
