The flight control system uses conventional ailerons, elevator Each wing has top and bottom shells made of and rudder. Each wing has two I-shaped spars with webs made form GFRP/rigid foam sandwich and caps made from CFRP bands. The cantilever wing is a semi-monocoque structure. Hydraulic pressure operates each disc brake. Each main wheel has a disc brake on the inside. The nose leg attaches to the forward fuselage. The main legs attach to the fuselage center-section. The fixed tricycle landing gear has fairings attached to each leg. A polyurethane paint finish protects the outside skin from ultraviolet rays and humidity. A glazed rear passenger door gives access to the rear seats from the left side of the airplane. This gives a good all-round view from the cockpit. The one-piece canopy has a large quantity of wrap-around glazing. The trailing edge has a conventional elevator and a trim tab. It has top and bottom shells made of GFRP. The horizontal stabilizer is a semi-monocoque structure. Standard ailerons and electrically operated flaps attach to the trailing edge of the wing. Four large bolts attach each wing to the fuselage main bulkheads. The wings attach to the fuselage center section. The vertical stabilizer has two GFRP half-shells that are part of the fuselage shells.

It has the main bulkheads which connect to the spars in each wing. The center section makes the bottom of the cockpit. Left and right half-shells bond together with a center section to make the fuselage. Uni -directional carbon fiber bands give extra strength and stiffness in many areas.

The semi-monocoque fuselage is a glass-fiber reinforcedplastic (GFRP) shell with GFRP bulkheads and stiffeners. This gives a very strong but light structure.

The airplane structure is fiber-reinforced plastic composite. Description The DA 40 NG is a single-engine, four seat, low-wing monoplane. Otto-Straße 5, A 2700 Wiener Neustadt, Austria, is the manufacturer of the DA 40 NG airplane. ATA 03 – GENERAL DESCRIPTION General Diamond Aircraft Industries Gmb.
