(4) Determination of effectively connected income
For purposes of this chapter, United States source gross transportation income of any taxpayer shall not be treated as effectively connected with the conduct of a trade or business in the United States unless—
(A) the taxpayer has a fixed place of business in the United States involved in the earning of United States source gross transportation income, and
(B) substantially all of the United States source gross transportation income (determined without regard to paragraph (2)) of the taxpayer is attributable to regularly scheduled transportation (or, in the case of income from the leasing of a vessel or aircraft, is attributable to a fixed place of business in the United States).
