What happened
On 16 June 2009, a Gemini Flash IIA, registration G-MTIA, was conducting a private sightseeing flight near the Lleyn Peninsula. The flight, which included the pilot and one passenger, was operating in clear weather conditions with light winds ranging from 6 to 10 mph.
As the aircraft approached Caernarfon Airport for landing on Runway 20, the pilot encountered difficulties maintaining stability. Although the aircraft's trim speed was set for 53 mph, the pilot noted that the aircraft was flying significantly slower, at approximately 42 to 45 mph. Just before crossing the runway threshold, a gust of wind caused the aircraft to drift left of the centerline. The aircraft touched down on its left main wheel, which triggered a roll to the right. The trike then pivoted on the right main wheel, causing the starboard wing to strike the ground and fold backwards. The aircraft eventually came to a rest on its right side after sliding along the runway.
Both occupants sustained minor injuries and were able to exit the aircraft without assistance.
The investigation
The investigation was based on the aircraft accident report submitted by the pilot. Investigators examined the flight conditions, the aircraft's configuration, and the sequence of events leading to the loss of control during the landing phase. The assessment focused on the aircraft's speed relative to its trim setting and the impact of wind gusts on the approach stability.
