About the TH55A

The Hughes TH55A is a piston-powered training rotorcraft featuring a single engine and accommodations for two crew members seated side by side in an open-framework fuselage. It is primarily suited for primary flight instruction and basic rotary-wing training duties.

Developed from a light civil helicopter family, the type achieved widespread military adoption and trained tens of thousands of service pilots during a lengthy operational career. The layout incorporates a fully articulated main rotor system linked directly to mechanical flight controls without hydraulic boost, providing direct feedback to the student pilot.
