It is kept at Hangar 10 of the FAA's Mike Monroney Aeronautical Center.","why_significant":"The nomination argues the aircraft represents a type that transformed commercial aviation and advanced military aviation in World War II. From 1957 to 1981 it served the CAA/FAA in flight inspection, and it is the last of over 60 modified DC-3s still in the FAA inventory. It is also cited as a significant engineering design and a rare survivor of a once common type.","narrative":"Douglas DC-3 N-34 is a twin-engine, all-metal transport airplane built in Oklahoma City in 1945 as a TC-47B for the U.S. Navy. After Navy storage, it entered Civil Aeronautics Administration service in 1957 and later flew for the Federal Aviation Administration as a flight inspection aircraft, checking navigation and landing aids until 1981. It is the last of more than 60 DC-3s modified for that work still held in the FAA inventory. It remains operable, wears an early 1950s CAA paint scheme with orange trim, and is housed at the FAA's Aeronautical Center in Oklahoma City. The nomination presents it as representative of an aircraft type that reshaped the airline industry and served in World War II, Korea and Southeast Asia. It also credits the design with innovations such as a low wing, retractable gear within the engine nacelles and split flaps. Only 410 of over 10,000 built are still registered in the United States, making it a rare survivor.","period_of_significance":"1945-1956, 1957-1981","architect_builder":"Douglas Aircraft Company","architectural_style":"OTHER: Transport Airplane","criteria":["A","C"],"status_note":"In operable condition; flown in the airshow season as an educational display airplane and housed in an enclosed hangar when not in use.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:24.019631-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OK/97000443.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/86511788","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q109999896"},"indexable":true,"url":"https://nationalhistoricalregister.com/texas/potter-county/douglas-dc-3-airplane-n34-97000443/"}
