What happened
On 12 April 2007, a private flight involving a Poisk-06 microlight, registration ZU-DZF, resulted in a fatal accident near the Saldanha-Vredenburg Aerodrome. While operating in the circuit, the aircraft was observed by Air Traffic Control radar performing much wider patterns than standard procedures.
As the aircraft approached Runway 02, witnesses—including an instructor from another aircraft in the same circuit—observed the pilot performing a sharp left turn to establish a long final approach. During this maneuver, the aircraft's nose pitched up violently. The aircraft subsequently entered a stall and dived into the terrain, resulting in one fatality.
The investigation
Investigators examined the wreckage and the engine at the accident site and through follow-up inspections at an approved overhaul facility. The investigation focused on the mechanical state of the aircraft and the pilot's credentials.
Technical inspections of the engine and airframe revealed no evidence of structural failure or mechanical malfunction prior to the impact. All control surfaces were intact, and the damage observed on the wings and fuselage was determined to be secondary to the high-speed, nose-first impact with the ground. The investigation also noted that the aircraft's logbooks were unavailable, making it impossible to verify maintenance history.
Findings
Several critical factors contributed to the accident. The investigation established that the pilot executed a steep turn that caused a loss of airspeed and altitude. In an attempt to recover, the pilot's aggressive pitch-up input triggered a stall from which recovery was impossible at the low altitude.
Further findings highlighted significant regulatory and proficiency issues:
- The pilot was flying with an expired pilot's licence and an expired medical certificate.
- The aircraft's Proving Authority to Fly had expired in May 2006.
- The pilot demonstrated a lack of proficiency, having not updated his flying logbook since August 2003.
- Evidence of poor airmanship was noted, including the pilot's visible struggle with radio communications prior to takeoff.
