(3) Type certificates, and changes to those certificates, for rotorcraft except those rotorcraft that are designated exclusively for aerial work operations. (b) Each person who applies under GACAR Part 21 for a type of airworthiness certificate specified in this part must show compliance with the applicable requirements of this part, in addition to the applicable airworthiness requirements. A noise certification statement for an individual aircraft is indicated by annotations on the airworthiness certificate issued to the aircraft under Subpart F of GACAR Part 21.

§ 36.3 Requirements as of Date of Application.p.2
Unless otherwise specified, the date to be used in determining the applicability of the standards in this part must be the date of application submitted to the State of Design for a type certificate, or the date of application under an equivalent prescribed procedure by the certificating authority of the State of Design except in special cases where the certificating authority accepts an extension of this period.
§ 36.5 Compatibility with Airworthiness Requirements.p.3
It must be shown that the aircraft meets the airworthiness regulations constituting the type certification basis of the aircraft under all conditions in which compliance with this part is shown, and that all procedures used in complying with this part, and all procedures and information for the flight crew developed under this part, are consistent with the airworthiness regulations constituting the type certification basis of the aircraft.

§ 36.21 Procedures, Noise Levels and Other Information.p.6
(a) All procedures, mass, configurations, and other information or data employed for obtaining the certified noise levels prescribed by this part, including equivalent procedures used for flight, testing, and analysis, must be developed and approved by the President or another authority acceptable to the President. Noise levels achieved during type certification must be included in the Aircraft Flight Manual.
(b) Where supplemental test data are approved for modification or extension of an existing flight data base, such as acoustic data from engine static tests used in the certification of acoustical changes, the test procedures, physical configuration, and other information and procedures that are employed for obtaining the supplemental data must be developed and approved by the President or another authority acceptable to the President.
§ 36.23 Manuals, Markings, and Placards.p.6
(a) If an Aircraft (Airplane or Rotorcraft) Flight Manual is approved, the approved portion of the Aircraft Flight Manual must contain the following information. If an Aircraft Flight Manual is not approved, the procedures and information must be furnished in any combination of approved manual material, markings, and placards.
(1) For transport category large airplanes and jet airplanes, the noise level information must be one value for each flyover, lateral, and approach as defined and required by this part, along with the maximum takeoff mass/weight, maximum landing mass/weight, and configuration.
(2) For propeller driven small airplanes, the noise level information must be one value for takeoff as defined and required by this part, along with the maximum takeoff mass/weight and configuration. (3) For rotorcraft, the noise level information must be one value for each takeoff, flyover, and approach as defined and required by GACAR §36.11(j), or one value for flyover as defined and required by GACAR §36.11(m), at the maximum takeoff mass/weight and configuration.
(b) If supplemental operational noise level information is included in the approved portion of the Aircraft Manual, it must be segregated, identified as information in addition to the certificated noise levels, and clearly distinguished from the information required under GACAR §36.21(a).
(c) For transport category large airplanes and jet airplanes, for which the mass used in meeting the takeoff or landing noise requirements of this part is less than the maximum mass established under the applicable airworthiness requirements, those lesser mass/weights must be furnished, as operating limitations in the operating limitations section of the Aircraft Flight Manual. Further, the maximum takeoff mass must not exceed the takeoff mass that is most critical from a takeoff noise standpoint.
(d) For propeller driven small airplanes and for propeller-driven, commuter category airplanes for which the mass used in meeting the flyover noise requirements of this part is less than the maximum mass by an amount exceeding the amount of fuel needed to conduct the test, that lesser mass/weight must be furnished, as an operating limitation, in the operating limitations section of an approved Aircraft Flight Manual, in approved manual material, or on an approved placard.
(e) For primary, normal, transport, and restricted category helicopters, if the mass used in meeting the takeoff, flyover, or approach noise requirements as defined and required by GACAR §36.11(j), or the mass used in meeting the flyover noise requirement as defined and required by GACAR §36.11(m) is less than the certificated maximum takeoff weight established under either GACAR §27.25(a) or §29.25(a), that lesser mass/weight must be furnished as an operating limitation in the operating limitations section of the Aircraft Flight Manual, or on an approved placard.
(f) Except as provided in paragraphs (c), (d), and (e) of this section, no operating limitations are furnished under this part.
