DESCPRIPTION AND OPERATION
OF AIRCRAFT AND SYSTEMS
7.1 THE AIRCRAFT
The aircraft EXTRA 300/S is designed and developed by EXTRA Flugzeugproduktions- und
Vertriebs- GmbH, Dinslaken 46569 Hünxe, Federal Republic of Germany, in accordance
with the U.S. Federal Aviation Regulations, part 23, categories normal and acrobatic to fullfill
the primary flight training, normal operation rules and acrobatic training up to the unlimited
acrobatic level.
EXTRA 300/S is a light weight, robust, single piston-engined, one-seat aircraft with a
fuselage structure in tig-welded steel-tube construction.
The landing gear, wing, and tail are made of epoxy, reinforced with glass- and carbonfiber.
The items are qualified up to 72°C.
The standard aircraft is designed to operate within a range of ambient air temperature from -
20°C to +44°C (-4°F => 111°F) at sea level. It is possible to start the engine using the
aircraft battery at -20°C (-4°F) without preheating. Below -10° C (+14°F) OAT a special oil
breather line must be adapted (available as kit).
7.2 FUSELAGE
The fuselage structure consists of a steel tube construction integrating the wing and
empennage connections as well as the seat. The lower front part of the fuselage and the
sides below the wing are faired with aluminium sheet metal. Within the exhaust area
stainless steel sheet metal is used. To improve pilots view for acrobatic maneuvers a
Lexan
®
window is installed in the lower fuselage skin. The rear part of the fuselage is
covered with Ceconite
®
102.
The upper fuselage body surface is one part from firewall to vertical stabilizer including the
correlated canopy frame. It consists of a kevlar laminate.
The canopy frame itself is constructed by carbon laminate. The canopy is one part, opens to
the right and is held in the open position by a belt. Emergency jettisonning is achieved by
simply unlatching the canopy. For additional pilots protection a roll bar is installed behind the
pilots seat.
