The flight of 16 October ended when Cody attempted a turn to avoid trees and a wingtip touched the ground. The resulting crash caused substantial damage, and the rest of the year was spent in repairing it and making major modifications. The gap between the wings was increased from 8 ft (2.44 m) to 9 ft (2.74 m), the booms carrying both sets of control surfaces lengthened, and provision for lateral control made by installing a wing-warping system and fitting differentially-moving surfaces at each end of the elevator. The radiators were moved to the aft interplane struts, the triangle of canvas that had stretched between the trailing edge of the upper wing and the top of the rudder was removed, and the small vertical stabiliser was moved from above the top wing to a position between the centre booms supporting the elevator, and linked to the rudder control. New larger propellers were fitted.
