## Abstract

This action prohibits flight operations within the Tripoli (HLLL) Flight Information Region (FIR) by all U.S. air carriers; U.S. commercial operators; persons exercising the privileges of a U.S. airman certificate, except when such persons are operating a U.S.- registered aircraft for a foreign air carrier; and operators of U.S.- registered civil aircraft, except when such operators are foreign air carriers.
