皇冠体育app

Jodel DR1051 (Modified), G-AYGD

Summary:

皇冠体育app pilot had been cleared for an immediate takeoff from Runway 30. 皇冠体育app takeoff was initiated from abeam an intersection while a passenger jet was in the process of lining up on the full runway length. 皇冠体育app surface wind was from 230潞(M) at 10 kt and the runway surface was dry. 皇冠体育app pilot was aware of the crosswind and delayed raising the tail wheel during the takeoff. However, as he did so the aircraft yawed to the left and this could not be controlled by the application of full right rudder combined with differential braking. 皇冠体育app pilot reduced power to idle and concentrated on controlling the subsequent run off onto the grass. Unbeknown to the pilot, there was a shallow ditch at the runway鈥檚 edge and on encountering the ditch the aircraft鈥檚 undercarriage collapsed. 皇冠体育app pilot and his two passengers were uninjured and able to vacate the aircraft without assistance before the airport emergency services arrived. 皇冠体育app left yaw at the point of raising the tail wheel was caused by a combination of the propeller wash, the reduction in directional stability of the aircraft as the tail-wheel is raised, asymmetric blade effect, torque reaction and the gyroscopic forces acting on the aircraft as it pitched forward. 皇冠体育app aircraft was subsequently towed clear of the runway to allow continued operations.
