The '''Extra Flugzeugbau EA300''' is a two-seat [[aerobatics|aerobatic]] [[monoplane]] capable of Unlimited category [[Competition aerobatics|competition]]. It was designed in [[1987 in aviation|1987]] by [[Walter Extra]], a [[German people|German]] aerobatic pilot, and built by [[Extra Flugzeugbau]].

==Design and development==
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.<ref name="Janes 93 p100">Lambert 1993, p. 100.</ref> A symmetrical [[airfoil]], mounted with a zero [[angle of incidence (aerodynamics)|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 O-540|Lycoming AEIO-540]] which produces 300 horsepower (224&nbsp;kW).<ref>{{cite web |title=Extra 300L |url=https://aircombatmuseum.com/?page_id=279 |website=Air Combat Museum |access-date=2025-04-16}}</ref>

The first two-seat Extra 300 made its maiden flight on 6 May 1988, with German [[type certificate|type certification]] following on 16 May 1990. The single-seat Extra 300S flew on 4 March 1992.<ref name="Janes 93 p100"/>

The Extra 300 is stressed for ±10&nbsp;G with one person on board and ±8&nbsp;G with two. Some Extra 300s are [[aircraft registration|registered]] in the experimental category under a [[Special Certificate of Airworthiness]] in the U.S., while others are [[type certificate|type certified]] in the aerobatic category.<ref name="Wagstaff">{{cite web|url = http://www.youngeagles.org/questions/afmviewfaq.asp?faqid=654|title = Ask the Expert|access-date = 2009-01-03|last = Wagstaff|first = Patty|year = 2009|archive-url = https://web.archive.org/web/20090210121104/http://www.youngeagles.org/questions/afmviewfaq.asp?faqid=654|archive-date = 2009-02-10|url-status = live}}</ref>

==Maintenance and operating costs==

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.<ref>{{cite web |title=AAIB Investigation to Extra EA 300L, G-ZXEL |url=https://assets.publishing.service.gov.uk/media/6409cf258fa8f55609b1413f/Extra_EA_300-L_G-ZXEL_04-23.pdf |website=Air Accidents Investigation Branch (UK) |date=April 2023 |access-date=2025-04-16}}</ref>

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.<ref>{{cite web |title=EXTRA EA 300L – Specifications, Performance, Operating Cost |url=https://planephd.com/wizard/details/602/EXTRA-EA-300L-specifications-performance-operating-cost-valuation |website=Planephd.com |access-date=2025-04-16}}</ref> Fuel consumption is typically 16.5 gallons per hour, with an average fuel cost of US$5.40 per gallon, amounting to US$88.94 per hour in fuel alone.<ref>{{cite web |title=EXTRA EA 300L – Specifications, Performance, Operating Cost |url=https://planephd.com/wizard/details/602/EXTRA-EA-300L-specifications-performance-operating-cost-valuation |website=Planephd.com |access-date=2025-04-16}}</ref>
