Eurocopter AS 355F1, Andover, England, Dec. 2, 2003–G-XCEL was on a test flight after it had been fitted with overhauled rotor drive gearboxes. Witnesses heard a “loud screeching mechanical noise,” then saw the tailboom appear to fold forward alongside the cabin and saw the helicopter fall to the ground. The pilot was killed, as were the two maintenance engineers on board.
