The Extra Flugzeugbau EA300 is a two-seat aerobatic monoplane capable of Unlimited category competition. It was designed in 1987 by Walter Extra, a German aerobatic pilot, and built by Extra Flugzeugbau.
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 220 kW (300 hp). [2]
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. [3]
The Extra EA-300 series, widely used in aerobatic training and competition, has maintenance and operational requirements consistent with its high-performance design.
Regular inspections are mandated to ensure continued airworthiness. A 50-hour inspection typically includes checks on the elevator trim system, while a 1,000-hour inspection involves detailed evaluations of trim tab hinges and actuator levers for wear or damage. [4]
Operating costs include both fixed and variable expenses. The average variable operating cost is approximately US$152.50 per flight hour, including fuel, oil, maintenance, and overhaul reserves. [5] Fuel consumption is typically 62 L (16.5 US gal) per hour ,
