This Subpart prescribes rules governing the identification of—
(1) aircraft, aircraft engines, and propellers:
(2) critical parts:
(3) certain replacement and modification parts.
(a) Each person who manufactures an aircraft or aircraft engine under Part 148 must identify the aircraft or engine by means of a fireproof data plate that is—
(1) marked with the identification information prescribed in 21.805 by etching, stamping, engraving, or other method of fireproof marking; and
(2) secured in such a manner that it is not likely to be—
(i) defaced or removed during normal service; or
(ii) lost or destroyed in an accident; and
(3) for an aircraft other than a manned free balloon, secured to the fuselage so that it is legible to a person on the ground—
(i) at an accessible location near an entrance; or
(ii) externally on another part of the fuselage; and
(4) for an aircraft engine, secured to the engine at an accessible location; and
(5) for a manned free balloon—
(i) secured to the balloon envelope; and
(ii) located where it is visible to the operator when the balloon is inflated.
(b) Each person who manufactures a manned free balloon must, in addition to paragraph (a), permanently and legibly mark the basket and any heater assembly with—
(1) the manufacturer's name; and
(2) a part number or an equivalent; and
(3) a serial number or an equivalent.
(c) Each person who manufactures a propeller, propeller blade or propeller hub under Part 148 must identify it by means of a fireproof data plate, or by etching, stamping, engraving, or other method of fireproof marking, that—
(1) contains the identification information prescribed in rule 21.805; and
(2) is placed on a non-critical surface; and
(3) is not likely to be—
(i) defaced or removed during normal service; or
(ii) lost or destroyed in an accident.
The identification information that is required to be marked on the data plate under rule 21.803(a)(1), and for the identification of a propeller, propeller blade, or propeller hub under rule 21.803(c)(1) must include—
(1) the manufacturer's name; and
(2) the model designation; and
(3) the manufacturer's serial number; and
(4) if applicable, the type certificate or type acceptance certificate number; and
(5) if applicable, the manufacturing organisation certificate number or foreign equivalent; and
(6) for an aircraft engine, the established rating; and
(7) any other information that the Director may require.
(a) Except as provided in paragraph (b), a person must not remove, alter, or replace any of the following without the approval of the Director—
(1) the identification information that is required under rule 21.803(a)(1) to be marked on a data plate:
(2) the identification information that is required under rule 21.803(c)(1) to identify a propeller, propeller blade, or propeller hub:
(3) the part number and serial number that is required under rule 21.811 for the identification of a critical part.
(b) A person performing maintenance in accordance with Part 43 may remove, alter, or replace the identification information referred to in paragraphs (a)(1) and (a)(2) and the part and serial number referred to in paragraph (a)(3) if the removal, alteration, or replacement is carried out in accordance with a method, technique, or practice that is acceptable to the Director.
(a) Except as provided by paragraph (b), a person must not remove or reinstall the data plate containing the identification information prescribed in 21.805 without the approval of the Director.
(b) A person performing maintenance in accordance with Part 43 may remove or reinstall the data plate containing the identification information prescribed in rule 21.805 if—
(1) the removal of the data plate is necessary during the maintenance; and
(2) the data plate is removed and reinstalled in accordance with methods, techniques, and practices acceptable to the Director; and
(3) the removed data plate is reinstalled on the product or part from which it was removed.
Each person who manufactures a critical part must permanently and legibly mark the part with—
(1) a part number or an equivalent; and
(2) a serial number or an equivalent.
(a) Except as provided in paragraph (b), each person who manufactures a replacement or modification part or appliance under an authorisation required by Subpart K must, in addition to the identification information prescribed in rule 21.805, permanently and legibly mark the part or appliance with—
(1) the letters ‘NZTSO’ or ‘NZPMA’ as appropriate; and
(2) the name, trademark, or symbol of the holder of the authorisation; and
(3) the part number; and
(4) the name and model designation of each product issued with a type certificate or type acceptance certificate, on which the part is eligible for installation.
(b) Each person who manufactures a replacement or modification material, part, or appliance under rule 21.303(2) must permanently and legibly mark the material, part, or appliance in such a manner as to ensure it can be—
(1) identified separately to those otherwise acceptable materials, parts, and appliances; and
(2) clearly related to its manufacturing data.
(c) If a material, part, or appliance is too small or it is otherwise impractical to mark the material, part, or appliance with the information required by paragraphs (a) or (b), the information must be recorded on a tag attached to the material, part, appliance, or its container.
(d) Where the marking required by paragraph (a)(4) is so extensive that to record it on a tag is impractical, the tag attached to the material, part, appliance, or the container may refer to a specific readily available manual or catalogue for the name and model designation of each product issued with a type certificate or type acceptance certificate, on which the material, part, or appliance is eligible for installation.
