§160.156-23 Procedure for approval of design, material, or construction change.
(a) Each change in design, material, or construction from the plans approved under 46 CFR 159.005-13 and §160.156-13(h) of this subpart must be approved by the Commandant before being used in any production rescue boat. The manufacturer must submit any such change following the procedures set forth in §160.156-9 of this subpart, but documentation on items that are unchanged from the plans approved under 46 CFR 159.005-13 and §160.156-13(h) of this subpart need not be resubmitted.
(b) Unless determined by the Commandant to be unnecessary, a prototype rescue boat with each change described in paragraph (a) of this section must be made and tested according to the procedures for new approvals in §§160.156-9 through 160.156-13 of this subpart.
(c) Determinations of equivalence of design, construction, and materials will be made by the Commandant only.
