Flight Standards Service-Civil Aviation Registry-Aircraft Registration Branch Responsibilities
The Aircraft Registration Branch issues approximately 70,000 aircraft registration certificates and processes approximately 225,000 documents affecting title to or interest in aircraft, engines, propellers, and air carrier spare part locations annually. The Registry reserves and assigns all U.S. identification marks (N-Numbers) to U.S. civil aircraft.
We maintain the permanent records of over 320,000 active civil aircraft and provide electronic access to those records for review to users of the Public Documents Room located in the Registry Building at the Mike Monroney Aeronautical Center in Oklahoma City, Oklahoma.
We are responsible for the review, evaluation, and development of any new or amended regulations pertaining to aircraft registration and the recordation of documents contained in Title 14 Code of Federal Regulations, Parts 47 and 49, and petitions for exemptions thereof.
