The DA20-C1 aircraft has two cowlings. It has a top cowling and a bottom cowling. The two halves attach
to the airframe with camlock fasteners. The top cowling has a left and a right air intake. It also has an
inspection panel to give you access to the engine oil dipstick. The bottom cowling has one large air
intake.

Description

GFRP or CFRP moldings make the power plant top and bottom cowlings. A strip of carbon fiber bonded
to the edges of the cowlings makes them strong. Camlock fasteners installed around the edge of the
cowlings attach them to the airframe. A hinge attaches the oil filler access panel to the top cowling and a
rotary lock holds it closed. Polyurethane paint protects the outside skin from ultraviolet rays and humidity.
The insides of the cowlings have a layer of fire resistant paint applied for protection.
Two holes at the front of the top cowling supply ram air to cool the engine. The one hole at the front of
the bottom cowling supplies ram air to the air intake.
