The fuselage is aluminium with skin and wing formed of composites. The fuselage skin incorporates graphite stringers and Toray composites, as do the wing and nacelles.
The T tail configuration has conventional elevators and no rudder. The horizontal tailplane can be raised above the rotor wake to minimise pitching at transition phase.
Size of wing determined by fuel requirement vs centre of gravity and safety. It has two-segment, trailing edge flaperons.
Titanium/composites cross shafts keep both proprotors turning in event of single engine failure. A manual screw jack facility enables the proprotors to be tilted into helicopter mode if cross shafts fail.
