(a) You must presume that a firm that is certified as a DBE under part 26 is eligible to participate as an ACDBE. By meeting the size, disadvantage (including personal net worth), ownership and control standards of part 26, the firm will have also met the eligibility standards for part 23.

(b) However, before certifying such a firm, you must ensure that the disadvantaged owners of a DBE certified under part 26 are able to control the firm with respect to its activity in the concessions program. In addition, you are not required to certify a part 26 DBE as a part 23 ACDBE if the firm does not do work relevant to the airport's concessions program.
