Ryan Aeronautical aircraft in the FAA registry
The Ryan Aeronautical Company was founded by T. Claude Ryan in San Diego, California, in 1934. It became part of Teledyne in 1969, and of Northrop Grumman when the latter company purchased Ryan in 1999. Ryan built several historically and technically significant aircraft, including four innovative V/STOL designs, but its most successful production aircraft was the Ryan Firebee line of unmanned drones used as target drones and unmanned air vehicles.
Registered Ryan Aeronautical Aircraft
According to the FAA registry data as of 2026-10-16, there are 167 aircraft listed under the registry manufacturer name "RYAN AERONAUTICAL". Of these, 165 have valid registrations. All 167 aircraft are fixed-wing, single-engine models powered by reciprocating engines. The fleet consists of 148 standard class aircraft and 5 experimental class aircraft. Most of these registered Ryan Aeronautical aircraft were built between 1935 and 1949, with half of them constructed in 1941 or earlier.
Geographically, the highest concentration of these aircraft is in California, which holds 32 registrations. Texas follows with 17 registrations, and Florida has 13.
Ryan Aeronautical Models and Type Certificates
The registry covers seven distinct models. The ST3KR is the most numerous, with 116 aircraft built between 1941 and 1945. Each ST3KR is a two-seat aircraft. The ST-A model includes 23 aircraft built from 1935 to 1939, also seating two passengers. The ST-A SPECIAL variant accounts for 9 aircraft, built between 1937 and 1940. Other models in the registry include the PT-22 with 10 aircraft, the SCW-145 with 7 aircraft built in 1938, and the NAVION with a single registration.
Type certificate data sheets (TCDS) document the airworthiness standards for these models. The Federal Aviation Administration (FAA) issued TCDS A-749 for the ST3KR, ATC 571 for the ST-A, ATC 681 for the ST-A SPECIAL, and TC 658 for the SCW-145. Each model has its own page with specifications and the type certificate data sheet (TCDS), and every aircraft has a registration record by N-number.
