Summary

A transfer, lease, or security paper for aircraft or aircraft parts only becomes fully effective against everyone once it is filed under section 44107. Before filing, it only affects the person who made it, that person’s heirs or people they left property to, and anyone who actually knew about it. After filing, it is effective from the filing date against all people without any other filing. Two limits apply: a filing for a specifically named engine or propeller covers only that engine or propeller and is not changed by other filings, and a filing under the location-based rules covers only items at the place named. Which state, District, or territory law governs depends on where the paper was delivered; if the paper names a delivery place, it is assumed to have been delivered there. That rule does not override the Convention on the International Recognition of Rights in Aircraft (4 U.S.T. 1830) or the Cape Town Treaty. These rules do not apply to transfers made before August 22, 1938 (for 44107(a)(1)) or before June 20, 1948 (for 44107(a)(2)).

(3)a person having actual notice of the conveyance, lease, or instrument.
(b)When a conveyance, lease, or instrument is recorded under section 44107 of this title, the conveyance, lease, or instrument is valid from the date of filing against all persons, without other recordation, except that—
(1)a lease or instrument recorded under section 44107(a)(2)(A) or (B) of this title is valid for a specifically identified engine or propeller without regard to a lease or instrument previously or subsequently recorded under section 44107(a)(2)(C) or (D); and
(2)a lease or instrument recorded under section 44107(a)(2)(C) or (D) of this title is valid only for items at the location designated in the lease or instrument.

If the conveyance, lease, or instrument specifies the place at which delivery is intended, it is presumed that the conveyance, lease, or instrument was delivered at the specified place.
(2)This subsection does not take precedence over the Convention on the International Recognition of Rights in Aircraft (4 U.S.T. 1830) or the Cape Town Treaty, as applicable.
