The Hughes OH-6 Cayuse is a single-engine light helicopter designed and produced by the American aerospace company Hughes Helicopters. Its formal name is derived from the Cayuse people, while its "Loach" nickname is derived from Light Observation Helicopter (LOH) program under which it was procured, and likely the word "chopper", a common nickname for helicopters.
