What happened
On 25 June 2001, a Piper PA-32R-301T, registered ZS-MMP, was conducting a private flight from Wonderboom Airport toward Paradise Beach near Jeffrey’s Bay. While traversing the Free State province, the pilot encountered deteriorating weather characterized by low cloud and rain. The pilot, who did not hold an instrument rating, initially operated at FL085 before climbing to FL105. Radar tracking later showed the aircraft fluctuating between FL107 and FL098. During this period, the aircraft performed a high-rate turn from a southerly to a northerly heading and subsequently disappeared from radar.
An eyewitness on the ground observed the aircraft descending through low clouds and rain. The observer reported hearing an engine sound consistent with a spin or a spiral dive. The aircraft was seen falling uncontrollably and breaking apart in mid-air before striking the ground near Winburg. A post-impact fire further damaged the cockpit and cabin areas.
The investigation
SACAA AIID investigators examined the flight path, meteorological data, and eyewitness accounts to reconstruct the final moments of the flight. The investigation focused on the aircraft's performance during the encounter with inclement weather and the structural failure that occurred prior to impact. Meteorological records confirmed that the freezing level in the region was at level 095, indicating the potential for icing conditions at the altitudes the aircraft was occupying.
Findings
- The pilot was flying without an instrument rating into weather conditions involving clouds and rain.
- The aircraft encountered meteorological conditions associated with cloud and ice.
- It is believed that ice accumulation on the wings caused the pilot to lose control of the aircraft.
- The loss of control led to the aircraft exceeding its Never Exceed Speed (Vne).
- The structural integrity of the Piper PA-32R-301T could not withstand the aerodynamic forces, causing the aircraft to break up in flight.
- The accident resulted in 3 fatalities and no survivors.
