FAA Federal Aviation Regulations (FARS, 14 CFR)

If a person submitting a conveyance for recording wants the original returned to him, he must submit a true copy with the original. After recording, the copy is kept by the FAA and the original is returned to the applicant stamped with the date and time of recording. The copy must be imprinted on paper permanent in nature, including dates, and signatures, to which is attached a certificate of the person submitting the conveyance stating that the copy has been compared with the original and that it is a true copy.
