The Fairchild Hiller FH-1100 is a single-engine, single two-bladed rotor, light helicopter which began as a design entry into United States Army's Light Observation Helicopter program. The Hiller Model 1100 was not selected but after Hiller Aircraft was purchased by Fairchild Stratos, in 1964, the Model 1100 was successful marketed as a civilian helicopter, the FH-1100.

The FH1100 was produced until 1973. Something about Hiller Aviation here. Something about the RH-1100 production here. In 2000, the Type Certificate was purchased by FH1100 Manufacturing Corporation. FH1100 Manufacturing conducts remanufacturing and training but has not received a production certificate for the FH-1100, which it now calls the FHoenix.

[edit] Development

[edit] Light Observation Helicopter (LOH)

In October 1960, the Army submitted a request for proposals (RFP) for the Light Observation Helicopter (LOH). Hiller Aircraft (Hiller), along with 12 other manufacturers (including Bell Helicopter (Bell) and Hughes Tool Co. Aircraft Division (Hughes), entered the competition,[1] submitting their designs to a Navy team for evaluation. Hiller submitted the Model 1100, which was recommended by the Navy team and eventually selected as one of three winners of the design competition by the Army in May of 1961.[2] The Army designated the Model 1100 design as the YHO-5.[3][4]

Detailed design work began in November 1961, and the Model 1100 prototype made its maiden flight on 21 January 1963. Hiller produced a total of 5 copies of the Model 1100 to submit to the Army for the Test and Evaluation phase at Camp Rucker, Alabama in 1963. After the test and evaluation, Bell's YOH-4 was eliminated, and Hiller and Hughes competed in a program cost analysis bid for the contract. In 1965, Hiller was underbid by Hughes and the Army selected Hughes' YOH-6. Hiller protested the award, claiming that their bid had been leaked to Hughes, but the Army denied the protest[citation needed] and awarded Hughes a production contract for the OH-6A Cayuse.

[edit] Operational History

In 1967, when the Army reopened the LOH competition for bids because Hughes Tool Co. Aircraft Division couldn't meet the contractual production demands.[citation needed] Fairchild-Hiller failed to resubmit their bid with the YOH-5A, instead choosing to continue with commercial marketing of their civilian version, the FH-1100.[5]
