What happened
On 18 March 2005, a Delta Speed MK1 microlight, registration ZU-BUD, was conducting a private flight near Microland Aerodrome. The pilot, accompanied by one passenger, departed from Microland Aerodrome to visit a maize farm within the nearby General Flying Area to demonstrate various flight techniques.
After successfully performing climbs, descents, and medium turns at an altitude of approximately 6,000 feet, the pilot attempted a low-level maneuver over another aerodrome in the area. This maneuver was executed at an altitude of just 15 feet above the ground with an airspeed of roughly 48 mph. Following this, the pilot increased speed and initiated a right-hand climbing turn to avoid a steel pole located at the edge of the aerodrome. During this turn, the right wingtip of the aircraft struck crops in a maize field, triggering a horizontal spin that led to a ground impact. Both occupants of the aircraft escaped the accident without injury.
The investigation
The investigation examined the flight sequence, the aircraft's maintenance history, and the pilot's credentials. The Delta Speed MK1 had recently undergone its annual inspection on 10 March 2005, with only 3.7 flight hours accumulated since that certification. The aircraft held a valid Authority to Fly. While the pilot held a valid license, the investigation established that the pilot was not appropriately rated for this specific aircraft type. The impact resulted in damage to the aircraft's propeller, undercarriage, and wing.
Findings
- The primary cause of the accident was the right wingtip making contact with maize crops during a climbing turn.
- This contact induced a horizontal spin, causing the pilot to lose control and strike the ground.
- The pilot was performing low-level flight maneuvers at an altitude of 15 feet.
- The pilot lacked the appropriate rating for the aircraft type being operated.
