It’s a Plane: Significant Modifications do not Result in Substantial Transformation

Client Alert | 1 min read | 03.13.17

On March 10, 2017, U.S. Customs and Border Protection published a final determination under the Trade Agreements Act that the country of origin of a Brazilian-manufactured military cargo airplane would remain Brazil, even after the aircraft undergoes significant conversion into a civil fire-fighting aircraft within the United States. According to CBP, the U.S.-origin changes to the aircraft—which include removing and adding various systems and components to install fire suppression capability—are not sufficient to change the aircraft’s “fundamental identity” and thus, do not constitute “substantial transformation.” The CBP emphasized that the aircraft would maintain its “most important” systems, the “basic structural integrity and the aerodynamics of the aircraft” would remain unchanged, and there was no evidence to demonstrate meaningful changes to the aircraft’s power, speed and range, or to the electronics and instruments used to fly the plane.

See United States ex rel. Zafirov v. Fla. Med. Assocs., LLC, 751 F. Supp. 3d 1293 (M.D. Fla. 2024). That decision, penned by District Judge Kathryn Kimball Mizelle, was the first success story for a legal theory that has been gaining steam ever since Justices Thomas, Barrett, and Kavanaugh indicated they would be willing to consider arguments about the constitutionality of the qui tam provisions in U.S. ex rel. Polansky v. Exec. Health Res., 599 U.S. 419 (2023). In her opinion, Judge Mizelle held (1) qui tam relators are officers of the U.S. who must be appointed under the Appointments Clause; and (2) historical practice treating qui tam and similar relators as less than “officers” for constitutional purposes was not enough to save the qui tam provisions from the fundamental Article II infirmity the court identified. That ruling was appealed and, after full briefing, including by the government and a bevy of amici, the litigants stepped up to the plate this morning for oral argument....
