The
Extra Flugzeugbau EA300
is a two-seat

capable of Unlimited category
competition
. It was designed in
1987
by
Walter Extra
, a
German
aerobatic pilot, and built by
Extra Flugzeugbau
.
Design and development
[
edit
]
Design of the Extra 300 was based on the
Extra 230
, an early 1980s monoplane having a wing made of
wood
. The Extra 300 has a
welded
steel
tube fuselage covered in aluminium and fabric. The midset wing has a
carbon fiber
composite spar and carbon composite skins.
[1]
A symmetrical
airfoil
, mounted with a zero
angle of incidence
, provides equal performance in both upright and inverted flight. The landing gear is fixed
taildragger
style with composite main legs and fiberglass wheel pants. The powerplant is a
fuel-injected
Lycoming AEIO-540
which produces 300 horsepower (224 kW).
The first two-seat Extra 300 made its maiden flight on 6 May 1988, with German
type certification
following on 16 May 1990. The single-seat Extra 300S flew on 4 March 1992.
[1]
The Extra 300 is stressed for ±10 G with one person on board and ±8 G with two. Some Extra 300s are
registered
in the experimental category under a
Special Certificate of Airworthiness
in the U.S., while others are
type certified
in the aerobatic category.
