DESCPRIPTION AND OPERATION
OF AIRCRAFT AND SYSTEMS
7.1
THE AIRCRAFT
The aircraft EXTRA 330LX is designed and developed by EXTRA Flugzeugproduktions- und
Vertriebs- GmbH, Flugplatz Dinslaken, 46569 Hünxe, Federal Republic of Germany, in
accordance with the U.S. Federal Aviation Regulations, part 23, in the acrobatic category to
fullfill the primary flight training, normal operation rules and acrobatic training up to the
unlimited acrobatic level.
EXTRA 330LX is a light weight, robust, single piston-engined, two-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 (161,6°F). Not to exceed this temperature limit an
appropriate colour specification for composite structure is given by the manufacturer
document EA-03205.19.
To check the temperature inside the cockpit (potential "green house" effect) a reversible
temperature indicator (
STRUCTURAL OVERHEAT INDICATOR
) is applied on the wing main
spar in the carry-through section. After reaching the temperature limit of 72°C (161,6°F) the
word "
RISK
" appears on the red spot of this structural overheat indicator immediately and
flying is prohibited. When the structure cools down below this temperature limit the word
"
RISK
" disappears and you may go on with the preflight checklist.
a) Below 72°C (161,6°F)
b) At 72°C (161,6°F) or above
The standard aircraft is designed to operate within a range of ambient air temperature from
-20°C to +44°C (-4°F to 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 seats. The fuselage except the rear lower part, is
faired with an aramid/carbon laminate shell. Within the exhaust area stainless steel sheet
metal is used. The upper fuselage body surface is one part from firewall to vertical stabilizer
including the correlated canopy frame. Only the lower rear part of the fuselage is covered with
Ceconite
®
102.
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 pilot protection a roll bar is installed behind the
rear pilots seat.
