What happened
On 25 January 2003, a Titan Tornado 912 micro-light, registration ZU-JON, was engaged in a private pleasure flight. The flight path included departures from Heidelberg Aerodrome and visits to the Vaaldam before returning toward Solitude Aerodrome. During the flight, the pilot was accompanied by a 10-year-old passenger.
As the aircraft approached Solitude Aerodrome, a thunderstorm was moving in from the south, bringing heavy winds. The pilot made an initial attempt to land on Runway 30, but a powerful crosswind prevented a successful touchdown, forcing an overshoot. A subsequent attempt on Runway 20 also failed, leading to a go-around. While attempting a third landing on Runway 30, the aircraft entered a tight left turn to reposition for the approach. During this maneuver, the aircraft struck the ground approximately 500m east of the Runway 30 threshold. The impact resulted in two fatalities and the total destruction of the aircraft.
The investigation
Investigators examined the flight sequence and the meteorological conditions present at the time of the accident. The inquiry focused on the aircraft's performance during the landing attempts and the impact of the approaching thunderstorm. The investigation established that the aircraft was operating in strong, gusty winds, with southerly winds reaching speeds of 25 to 35 knots.
Findings
- The primary cause of the accident was an aerodynamic stall occurring during a tight left turn while the pilot was attempting to reposition the aircraft for landing.
- The aircraft was operating under significant environmental stress due to a nearby thunderstorm and high-velocity crosswinds.
- The pilot failed to recognize the critical warning signs that the aircraft was exceeding its operational limitations.
- A significant contributing factor was the pilot's decision to continue landing attempts in severe weather rather than diverting to a safer aerodrome.
