About the Maule M-7

The Maule M-7 is a rugged American short takeoff and landing (STOL) taildragger built by Maule Air in Moultrie, Georgia, since the 1980s. Designed for backcountry operations, the M-7 series features a high-wing configuration, conventional landing gear, and a reputation for getting in and out of unimproved strips that would ground most certificated aircraft. With takeoff rolls as short as 300 feet and landing distances under 400 feet depending on variant and conditions, the M-7 excels at mountain flying, bush operations, and remote airstrip access where pavement is optional and obstacles are plentiful.

The type is available with a range of powerplants from 180 to 235 horsepower, all driving a fixed-pitch or constant-speed propeller, and can be equipped with floats, skis, or tundra tires for operations on water, snow, or soft terrain. Its steel-tube fuselage and fabric-covered wings make field repairs practical, a key advantage for operators far from maintenance facilities. The M-7's sturdy construction, docile handling, and four-seat cabin have made it a favorite among Alaska bush pilots, backcountry enthusiasts, and agricultural operators who need an airplane that works as hard as they do.
