About the Maule M-5

The Maule M-5 is a rugged four-seat tailwheel aircraft built by Maule Air in Georgia from the early 1970s through the mid-1980s, designed for short-field operations and backcountry flying. Variants include the M-5-180C, M-5-210C (Lunar Rocket), M-5-220C (Lunar Rocket), and M-5-235C (Strata Rocket), each named for its Lycoming engine horsepower. The M-5 features a steel-tube fuselage with fabric covering, a high wing with full-span flaps, and oversized tires that allow operations from unimproved strips, sandbars, and mountain airstrips where most tricycle-gear aircraft cannot venture.

Its short takeoff and landing performance — typically under 500 feet over a 50-foot obstacle — made it popular with bush pilots, hunters, and remote-property owners across Alaska, the Mountain West, and Canada. The M-5 can carry four adults and baggage at a cruise speed around 140 mph, with a range of approximately 500 nautical miles depending on configuration. While never produced in large numbers compared to Cessna or Piper models, the M-5 earned a loyal following for its honest handling, simple systems, and ability to get in and out of places other singles cannot.
