About the Schweizer Aircraft Corporation 269C

The Schweizer 269C is a light three-seat piston helicopter that traces its lineage back to the Hughes 269 of the late 1950s. Originally designed by Hughes Helicopters as a simple, rugged trainer, the type was adopted by the U.S. Army as the TH-55 Osage for primary rotorcraft instruction during the Vietnam era. Schweizer Aircraft acquired the design in 1983 and continued production through 2010, refining the airframe with improved avionics and powerplant options while preserving the original's reputation for docile handling and low operating costs. The 269C variant introduced a more powerful Lycoming HIO-360 engine and an enlarged tail rotor, making it the most capable version of the family.

With a maximum gross weight just over 2,000 pounds and a never-exceed speed of 100 knots, the 269C occupies the entry-level segment of the helicopter market. Its fully articulated three-blade main rotor and aluminum semi-monocoque fuselage deliver predictable flight characteristics that have made it a staple of civilian flight schools worldwide. The type's simplicity (no hydraulics, no complex systems) translates to straightforward maintenance and relatively affordable operating economics for a turbine-free helicopter. Endurance is modest at roughly two hours, but the 269C's forgiving nature and excellent visibility from the bubble canopy continue to make it a popular choice for ab-initio training and personal use.

SkyMeter has tracked flights across airframes and operators, with the largest observed operator.
