The pilot was flying solo circuits from Runway 26 at Tatenhill Airfield. It was a warm day with a temperature of 24°C and sunny conditions.
Having completed a circuit and landing, the pilot prepared for the subsequent takeoff by raising the flaps. He then applied full power and began the takeoff roll. Just as the pilot lifted the tail off the runway, he experienced a cramp spasm in his right leg which caused him to straighten his leg to try and stop what he described as “excruciating pain”. This resulted in him increasing pressure on the right rudder pedal and the right brake. Despite quickly closing the throttle, the aircraft turned rapidly through 90°. Although it remained on the runway, the left landing gear collapsed as the aircraft slowed, causing it to rotate further and the propeller to contact the ground.
The pilot reported that there was little airflow in the cabin which, combined with the hot weather and a lack of fluid intake, might have contributed to the onset of cramp.
