What happened
On the night of 13 May 2003, a PIPER PA-28R-200, registration ZS-FWG, departed from Klerksdorp (FAKD) for a planned sightseeing flight. The flight was being conducted under private operations with the pilot and two passengers on board. Following a successful preflight inspection and engine power check, the aircraft took off from Runway 18.
During the initial climb, the pilot reported rotating at 70 mph and maintaining a climb speed of 90 mph. After confirming a positive rate of climb, the undercarriage was retracted, and all engine parameters appeared normal. However, shortly after this phase of flight, the pilot observed a decrease in airspeed and a negative climb rate on the vertical speed indicator. Sensing that the engine was failing to produce adequate power, the pilot attempted to identify the source of the malfunction but was unable to do so.
Unable to maintain altitude, the pilot executed a forced landing in a field located approximately 500 meters from Runway 18. The landing area was heavily obstructed by vegetation and trees. During the descent, the left wing of the aircraft struck a tree, which caused the wing to separate from the fuselage.
The investigation
Investigators examined the wreckage and the circumstances surrounding the engine's performance. The investigation focused on the period immediately following takeoff and the mechanical state of the engine's fuel delivery system. The inquiry established that while the initial takeoff parameters were within normal limits, a mechanical failure prevented the engine from sustaining the necessary power for continued flight.
Findings
- The aircraft experienced a restricted fuel flow in one of the fuel injector nozzles.
- This restriction prevented the engine from producing full power.
- The resulting loss of altitude necessitated a forced landing.
- The aircraft impacted trees and vegetation, leading to the separation of the left wing from the fuselage.
- The accident resulted in two serious injuries and one minor injury among the occupants.
