Porterfield aircraft in the FAA registry
The Porterfield Aircraft Corporation was an American aircraft design and manufacturing company founded in 1934 in Kansas by Edward E. Porterfield. Today, the legacy of this manufacturer is preserved in the Federal Aviation Administration (FAA) registry. As of October 16, 2026, the registry lists 77 aircraft under the manufacturer name "PORTERFIELD". These are all fixed-wing, single-engine aircraft powered by reciprocating engines. While the majority of these planes were built between 1935 and 1976, half of the registered fleet dates back to 1940 or earlier.
Registered Porterfield Aircraft Models
The registry contains 75 valid registrations across 10 distinct models. The most common model is the LP-65, with 27 aircraft registered. Built between 1940 and 1941, this two-seat aircraft is followed by the CP-65, which has 19 registered units from the same production years. Other notable models include the 35-70 with 9 registrations, the CP-50 with 8, and the FP-65 with 7. The registry also includes two registrations for the 35W model. Most of these aircraft are classified under the standard airworthiness category, with one exception listed as experimental.
Geographic Distribution and Type Certificates
Geographically, California holds the largest share of registered Porterfield aircraft with 15 units. Washington follows with 9 registrations, and Ohio has 7. The Type Certificate Data Sheets (TCDS) provide technical documentation for these models. TCDS A-720, held by Bradley Rankin, covers the LP-65, CP-65, and FP-65 models. TCDS TC 741, held by Vega Aircraft Corporation, covers the 35-70 model. Each model page on this site includes its specifications and TCDS details, allowing users to perform a Porterfield N-number lookup for specific airframes.
