Structure Wing, mainly of aluminium alloy with 11 spars, five ribs and single upper and lower skins, is attached to fuselage by machined aluminium fittings. Nose radome built by Brunswick corporation. Highly swept vortex control strakes along the fuselage forebody increase lift and improve directional stability at high angles of attack. The tail unit fin is a multispar, multirib aluminium structure with graphite epoxy skins, aluminium tip and glass fibre dorsal fin and root fairing. Tailplanes constructed of graphite epoxy composite laminate skins mechanically attached to a corrugated aluminium substructure.
Ventral fins are bonded aluminium skins.
Landing Gear Menasco hydraulically retractable type, nose unit retracting aft and main units forward into fuselage. Nosewheel is located aft of intake, to reduce the risk of foreign objects being thrown into the engine during ground operation, and rotates 90 during retraction to lie horizontally under engine air intake duct. Oleo-pneumatic struts in all units. All but two main unit components interchangeable. Brake by wire system on main gear, with Goodyear anti-skid units.
