Aircraft Bidder is proud to present this 1998 Extra 300L Featured in Microsoft Flight Simulator X!  If you have flown N105MM on MS Flight Simulator, you have flown this airplane!!  Also seen in AOPA Air Safety Institute and BruceAir videos. Recent Avionics Upgrades include three Garmin GI 275 EFIS Displays front and back, a Garmin GNC 355 GPS/Comm and Garmin ADS-B In & Out. The MT 3-bladed prop was just overhauled in February. Professionally maintained and a fresh Annual Inspection in January 2023.   1,000-hour airframe inspection and avionics upgrades completed at Southeast Aero.


AOPA's Extra 300L:

The Extra 300L is a two-seat, low-wing, aerobatic airplane powered by a fuel-injected Lycoming AEIO-540 engine, producing 300 horsepower.

The main wing is mounted at the bottom of the fuselage. It has a wingspan of 24 ft, giving it a roll rate up to 400° per second. The Extra 300 is stressed for ±10 G with one person on board and ±8 G with two.

The welded steel tube fuselage is covered in aluminum and fabric and the carbon fiber spar and carbon-composite skins create a symmetrical airfoil. Wings are mounted with a zero angle of incidence and provide equal performance in both upright and inverted flight.

This taildragger airplane sports a composite main gear and fiberglass wheel pants.


Extraordinary Generosity - How AOPA Acquired N105MM:

By Dave Hirschman

The question came without preface or preamble: “If I were to donate my Extra to AOPA, would the association have a purpose for it?” Bruce Williams, a flight instructor, aviation writer, and former Microsoft manager who played major roles in the company’s highly successful Flight Simulator programs, wasn’t kidding.

He had owned an Extra 300L for nearly two decades. It was well known from his “BruceAir” instructional videos, and I’d flown it (upside down over Michigan Avenue in Chicago) on my desktop computer when Microsoft’s 2006 Flight Simulator X came out.

Williams had used the Extra to provide unusual attitude and spin training, and the two-seat, 300-horsepower airplane migrated between his home in Seattle each summer and Boulder City, Nevada, every winter. He’d flown it very little during the previous two years, however, because of the COVID-19 pandemic, and now he was considering the future of N105MM, an unlimited aerobatic airplane with a unique pedigree.

His Extra had been gently flown (for an aerobat, anyway), was maintained to the highest standards, and almost never spent a night outdoors. If Williams decided to sell, N105MM could fetch a premium price. But Williams was sure his airplane still had lifesaving lessons to teach, and the AOPA Air Safety Institute could reach the largest number of general aviation pilots and help them avoid loss-of-control accidents—the single largest cause of fatal crashes. AOPA Air Safety Institute Senior Vice President Richard McSpadden enthusiastically backed the idea, and other association leaders saw roles for the specialized airplane in initiatives including AOPA’s high school education program and fundraising.
