The Ppl-rated pilot, who had three hours on the Colomban MC-15 Cri-cri (photo above), had altered the mixture setting on each engine’s carburettor and flew a circuit from Popham’s Rwy 03 during which both engines seemed to run normally. He then turned onto final approach and lowered landing flap, whilst still retaining a moderate power setting. At approximately 60 KIAS and at a height of 400-500ft agl he closed one throttle, followed by the second. As he closed the second throttle, the first engine stopped. He started to advance the throttle of the live engine but this then also stopped. He set up a glide approach, but during the flare, at about two feet, the right wing dropped and the aircraft sank onto the grass surface, landing heavily. During the touchdown, the pilot’s head struck the canopy but he was uninjured. He believes that the engines stopped due to the adjustment of the mixture controls on both carburettors, giving excessively lean conditions at low rpm whilst in flight.
