The semi-monocoque fuselage is a glass-fiber reinforced-plastic (GFRP) shell with bulkheads and
stiffeners. The one-piece canopy has a large quantity of wrap-around glazing. This gives a good
all-round view from the cockpit. The vertical stabilizer has two GFRP half-shells that are part of the
fuselage shell.
The cantilever wing is a semi-monocoque sandwich. It has an I-shaped spar with caps made from
carbon-fiber rovings. The left wing and the right wing attach to the fuselage. Each wing has a
stump spar. Three special bolts attach each wing to the fuselage. Standard ailerons and
electrically operated flaps attach to the trailing edge of the wing.
Polyurethane paint protects the outside skin from ultraviolet rays and humidity.
The fixed tricycle landing gear has optional fairings attached to each leg. The main legs attach to
the spar bridge and the nose leg attaches to the forward fuselage. Each main wheel has a disc
brake on the inside. Hydraulic pressure operates each disc brake.
The flight control system uses conventional ailerons, elevator and rudder. The DA20-C1 has 2
control sticks and 2 rudder pedal assemblies to operate the primary flight-controls. Push-pull rods
operate the ailerons and elevator. Cables operate the rudder. Electric motors operate the elevator
trim and wing flaps.
A Continental (IO-240-B), four cylinder, direct drive, horizontally opposed engine powers the
DA20-C1.
The airplane may be fitted with one of several different types of 2 bladed propeller. A Sensenich
W69EK7-63 wood propeller with 7/16” diameter attachment bolts. A Sensenich W69EK7-63G wood
propeller with a composite covering and 7/16” diameter attachment bolts. A Sensenich W69EK-63
wood propeller with 3/8” diameter attachment bolts. Airplanes can have a Hoffmann HO 14HM-175
157 fixed-pitch wood-composite propeller as an option.
The airplane has an aluminum fuel tank in the fuselage. The fuel tank is between the backrest of
the seat and the B-bulkhead below the floor of the baggage compartment.
The airplane has two sources of electrical power. A 12-volt battery supplies power when the engine
is not running. An alternator provides power when the engine is running. Switches and circuit
breakers control all electrical devices. An ignition key controls the magnetos. It also controls the
engine starter motor.
The DA20-C1 has a full range of flight instruments. These include pitot/static instruments to show
airspeed and altitude. Vacuum or electric driven instruments show attitude. The airplane has all
the usual engine instruments. It also has radio and navigation aids installed.
