PER CURIAM:
The judgment of conviction in this case for attempting to board an aircraft of Pacific Southwest Airlines with a concealed weapon is affirmed.
Defendant contends the Pacific Southwest Airlines (PSA) was not engaged in "air transportation." See 49 U.S.C. § 1301(10).
Inasmuch as PSA, although not certificated by the Civil Aeronautics Board, was properly engaged in the transportation of United States mails on some routes, we hold that 49 U.S.C. § 1472(1) was violated by Delacerda.
