The Fairchild Hiller FH-1100 is a single-engine turbine, single two-bladed rotor, light helicopter that was designed and produced by the American aircraft manufacturer Fairchild Hiller in the 1960s. Originally designated as the Model 1100, it was produced as the company's design submission for the United States Army's Light Observation Helicopter (LOH) program. It was one of the three winning designs in May 1961, after which the military designation Hiller YOH-5 was assigned; the prototype performed its maiden flight on 21 January 1963.
