Hiller aircraft in the FAA registry
Hiller Aircraft Corporation is an American aerospace company founded in 1942 by Stanley Hiller. Based in Firebaugh, California, the firm developed helicopters and was purchased by Fairchild Aircraft in 1964. It became independent again in 1994 and filed for Chapter 11 bankruptcy protection on November 21st, 2024.
Data from the FAA registry, current as of 2026-10-16, lists 242 aircraft under the manufacturer name "HILLER." There are 18 distinct models, with 236 valid registrations. Most of these rotorcraft were built between 1949 and 1993, and half were constructed in 1960 or earlier. The fleet consists of 241 rotorcraft powered by 213 reciprocating engines and 29 turboshaft engines. Airworthiness classifications include 126 standard, 41 restricted, and 39 multiple.
The registered Hiller aircraft are concentrated in specific regions. Texas holds 50 registrations, followed by California with 27, and Washington with 15. The UH-12E is the most common model, with 103 aircraft built between 1958 and 1993. The UH-12B follows with 35 units (1950–1963), and the UH-12C has 31 units (1955–1959). Other notable models include the UH-12D (22 units, 1957–1976), the UH-12A (16 units, 1949–1962), and the OH-23B (6 units).
Each model has its own page with specifications and the type certificate data sheet (TCDS). The TCDS 4H11, held by Siam Hiller Holdings Inc., covers the UH-12E. TCDS 6H2 covers the UH-12B and UH-12C, while TCDS 4H10 covers the UH-12D. The UH-12A is covered under TCDS 6H1. Every aircraft has a registration record by N-number for lookup purposes.
