Court Line Flight 95
During its take-off run, Piper PA-23 Aztec G-AYDE of McAlpine Aviation entered the active runway without permission.The pilots of the substantially damaged One-Eleven successfully aborted the take-off and the aircraft was evacuated using emergency slides, with no casualties.[1] At 15:19 Greenwich Mean Time, the One-Eleven received permission to taxi to holding point Delta where it was to await clearance.He fully opened both throttles and steered the aircraft to the right whilst attempting to lift the port wing over the Aztec.The port wing of the One-Eleven sliced through the cabin of the Aztec, killing the pilot instantly and injuring the passenger.Use of full reverse thrust and maximum braking enabled the take-off to be successfully aborted within the remaining runway length, with the damaged One-Eleven stopping 750 metres (820 yd) beyond the point of collision.Although the radio installation on the Aztec conformed to legislation then existing, its arrangement was criticised as the passenger/co-pilot could not hear in his headset transmissions made by the pilot.
