e. Section 45.15, Marking requirements for PMA articles, TSO articles, and critical parts.
(1) The former title of this section “Replacement and modification parts” was changed to “Marking requirements for PMA articles, TSO articles, and critical parts.”
(2) This section standardizes and consolidates marking requirements for PMA articles, TSO articles, and critical parts, including an identifier of the person who manufactured the part and the part number. In addition, TSO articles require the TSO number and letter of designation; any marking specifically required by the applicable TSO; and the serial number or date of manufacture or both, unless otherwise specified in the applicable TSO.
(3) This rule relocates the requirements of previous § 45.15(b) to paragraph (d) of this section. The rule requires marking information to be attached to any article that the FAA finds is too small or otherwise impractical to mark on the article and clarifies that this provision applies to all PAHs.
(4) This final rule retains the current “FAA-PMA” marking requirements. However, installation eligibility is no longer required on the article.
