Helio aircraft in the FAA registry
The Helio Aircraft Company was an American aircraft manufacturer founded in 1948. The Federal Aviation Administration (FAA) registry lists 120 aircraft under the manufacturer name "HELIO" as of October 16, 2026. Of these, 118 registrations are currently valid. The fleet consists mainly of fixed-wing, single-engine aircraft. Most of these planes were built between 1954 and 1984, with half constructed in 1967 or earlier.

The registry contains 11 distinct models. The H-295 is the most common variant, with 54 aircraft registered. These were built from 1965 to 1974 and seat six passengers. The H-391B follows with 16 registrations, built between 1954 and 1958 for four seats. Another 16 H-395 models are registered; these were built from 1958 to 1963 and seat five people.

Engine types vary across the fleet. Reciprocating engines power 117 of the aircraft, while three are turboprop. Airworthiness classes include standard for 102 aircraft, multiple for six, and experimental for three. Geographically, Alaska holds the most registrations with 45, followed by California with nine and North Carolina with eight.
Helio TCDS and Specifications
Type certificate data sheets (TCDS) provide the technical specifications for these models. TCDS 1A8, held by Helio Alaska Inc., covers the H-295, H-391B, H-395, HT-295, and H-250. Each model has its own page with specifications and the type certificate data sheet. Every aircraft has a registration record by N-number, allowing for a Helio N-number lookup to verify specific airframe details.
