Overview
Helio Aircraft Company was an American aircraft manufacturer established in 1948 to develop practical short-takeoff-and-landing aircraft for utility operations. Its origins lay in the Koppen-Bollinger Aircraft Corporation, founded in Massachusetts by Otto Koppen and Lynn Bollinger. The company focused on a light STOL design intended to operate from short, rough, or otherwise unimproved airstrips, a capability that distinguished its products from conventional light aircraft designed primarily for prepared runways. The company initially operated from Boston Metropolitan Airport in Canton, Massachusetts. By the time production of the Helio Courier began in the early 1950s, the business had adopted the Helio name and had moved manufacturing to Pittsburg, Kansas. The Courier became the company’s central product and its principal commercial identity. Its design emphasized low-speed handling, short-field performance, and utility rather than high-volume general aviation production. These characteristics made the aircraft relevant to bush flying, remote-area transportation, surveying, agricultural work, and other missions where runway length and surface quality were major constraints. Helio expanded its Kansas manufacturing presence by acquiring the plant at Atkinson Municipal Airport from Mid-States Manufacturing Company in July 1956. In 1959, it announced plans to move its factory to Tucson, Arizona. The Kansas facility later suffered extensive damage in a wildfire in March 1966, adding operational pressure to a company already working within the difficult economics of specialized aircraft manufacturing. In 1969, General Aircraft Corporation acquired the business. The company was subsequently identified as the Helio Aircraft Company and continued producing aircraft until 1974. That period ended amid a legal dispute in which General Aircraft initiated proceedings against the Central Intelligence Agency, alleging that the agency had sought to damage the business by arranging unlicensed production of the Courier. The available reference material describes the allegation and legal action but does not establish a final resolution. General Aircraft sold production rights to Helio Aircraft Ltd in 1977. An attempted restart did not immediately result in sustained manufacturing, and the enterprise remained largely inactive until 1980. Production of the Courier eventually resumed, but only 18 aircraft were built. In 1984, the company laid off 100 workers, and it was evicted from its factory the following February. These events marked the collapse of the later production operation rather than the end of interest in the aircraft designs themselves. The rights to the Courier and the Helio Stallion subsequently changed hands several times. In 2004, Helio Aircraft LLC of Prescott, Arizona acquired the rights and announced plans to bring both aircraft types back into production. The reference material does not confirm that the proposed restart achieved regular production. As a result, the historical Helio brand is best understood as an aircraft-manufacturing name associated primarily with specialized STOL utility aircraft, especially the Helio Courier, rather than as a currently verified mass-production manufacturer.
History
Helio Aircraft Company originated in 1948 as the Koppen-Bollinger Aircraft Corporation, founded in Massachusetts by Otto Koppen and Lynn Bollinger. The founders sought to develop a light utility aircraft capable of STOL operation, allowing it to use short and unimproved airstrips. The company was initially based at Boston Metropolitan Airport in Canton, Massachusetts. By the early 1950s, when manufacture of the Helio Courier commenced, the business had adopted the Helio name and had established production in Pittsburg, Kansas. The Courier became the company’s defining aircraft. Its commercial proposition centered on utility, ruggedness, and short-field performance rather than high-volume production or conventional touring-aircraft features. This made the aircraft suitable for bush flying and other operations in remote environments. Helio acquired its Pittsburg plant at Atkinson Municipal Airport from Mid-States Manufacturing Company in July 1956. In 1959, the company announced that it intended to move its factory to Tucson, Arizona. The Kansas facility was almost destroyed by a wildfire in March 1966, an event that materially complicated the company’s manufacturing activities. General Aircraft Corporation acquired the business in 1969. The operation continued producing aircraft under the Helio Aircraft Company name until 1974. After production stopped, General Aircraft commenced legal proceedings against the CIA, alleging that the agency had arranged unlicensed production of the Courier as part of an effort to ruin the company. The available source records the allegation and litigation but does not provide a confirmed legal outcome. In 1977, General Aircraft sold production rights to Helio Aircraft Ltd. An attempt to restart manufacturing did not immediately succeed, and the business remained largely inactive until 1980. Courier production was subsequently resumed, but only 18 aircraft were built. The company’s financial and operational difficulties continued: in 1984 it had to lay off 100 workers, and in February of the following year it was evicted from its factory. The rights to the Courier and the Stallion later moved between owners several times. In 2004, Helio Aircraft LLC, based in Prescott, Arizona, acquired the rights and announced plans to restore both aircraft types to production. The available reference does not verify that the proposed program reached sustained production. Helio is therefore principally remembered for the Courier and for its place in the history of specialized American STOL aircraft manufacturing.

STOL utility aircraft · 1950
Helio Courier
The Helio Courier was Helio’s principal aircraft and the product most closely associated with the company. It was designed as a utility-oriented STOL aircraft, emphasizing operation from short, rough, or unimproved airstrips. The design served the needs of bush and remote-area operators rather than focusing solely on conventional general aviation travel. Production began in the early 1950s, continued under different corporate owners, ended in 1974, and later resumed on a highly limited basis, with 18 aircraft built after the restart.
Utility aircraft
Helio Stallion
The Helio Stallion was another aircraft associated with the Helio production rights. The rights to the Stallion, along with those to the Courier, passed through several owners after the original manufacturing operation declined. In 2004, Helio Aircraft LLC announced plans to return the Stallion to production, but the available reference does not confirm that the proposed restart achieved sustained manufacturing.
Controversies

Allegations of CIA-backed unauthorized Courier production
General Aircraft Corporation initiated legal proceedings against the CIA, alleging that the agency had organized unlicensed production of the Helio Courier with the aim of damaging the company. The available reference records the allegation and litigation but does not establish the case’s final outcome.
