What happened
On 5 July 1998, a Team Minimax 91, registration G-MYYR, was participating in the Popular Flying Association Rally at Cranfield Airport, Bedfordshire. The pilot, operating the microlight on a private flight, took off from the grass runway 22. Meteorological data obtained prior to the flight indicated surface winds from 130° with gusts reaching 30 knots.
Shortly after rotation at 65 kt, the aircraft reached an altitude of approximately 100 feet. During the climb, witnesses observed the aircraft exhibiting signs of a near-stall condition, characterized by the wings rocking laterally. The pilot reported that a sudden gust caused the aircraft to roll 90° to the right, which was accompanied by a significant drop in airspeed. In an effort to avoid spectators positioned to the right of the flight path, the pilot attempted to maneuver the aircraft, but the right wing subsequently stalled. The aircraft impacted the runway at a speed of approximately 30 mph.
The investigation
The investigation was based on the aircraft accident report submitted by the pilot. The assessment focused on the flight conditions and the aircraft's performance during the takeoff roll and initial climb. The investigation established that the aircraft sustained substantial damage to the engine bay, canopy, undercarriage, and the right wing. The pilot, who sustained minor injuries, was assisted from the wreckage by airfield fire services and bystanders.
Findings
- The aircraft was operating in high-wind conditions, with gusts recorded up to 30 knots.
- A sudden wind gust caused a 90° right roll and a loss of airspeed.
- The pilot's attempt to steer away from spectators led to a wing stall and subsequent impact with the runway.
