What happened
On April 19, 2000, a Cessna 172 (registration ZS-ILI) departed Rand Airport for a flight to Messina. The aircraft was carrying a pilot and three passengers. Shortly after takeoff from Runway 29, Air Traffic Control (ATC) instructed the pilot to execute a right turn and report once outbound. However, controllers observed the aircraft flying at a low altitude and performing a left turn instead of the requested right turn.
Following the deviation, ATC queried the pilot to ensure operations were normal. After an initial period of silence, the pilot requested permission to return to the airport. The controller directed the aircraft to join the left base for Runway 35. During this maneuver, the controller lost visual contact with the aircraft. When asked for a position update, the pilot reported being over Alberton. While the aircraft appeared to be on a stable left base for Runway 35 without losing altitude, the situation changed rapidly. As the aircraft prepared to turn onto final approach, the controller noticed the plane losing height and disappearing below the horizon to the south. No further radio contact was made, and emergency fire crews were dispatched to the site.
The investigation
The investigation focused on the flight path deviations and the sudden loss of altitude during the approach phase. Investigators examined the mechanical state of the engine and the aircraft's performance during the departure and return maneuvers. The inquiry established that the aircraft's inability to follow instructions and its subsequent descent were linked to a specific mechanical failure.
Findings
- The aircraft suffered from insufficient engine power during the flight.
- A loose magneto caused incorrect ignition timing, which directly impacted the engine's performance.
- This mechanical failure resulted in the aircraft being unable to maintain or increase its altitude, leading to the crash.
Fatalities and injuries
- 1 fatality
- 3 injuries
