# §36.0. Applicability and statements of compliance for aircraft that do not conform to a type certificate.

- (a) **General applicability.** This part may be used by persons seeking to show compliance with noise standards for aircraft described in [§ 21.190](/cfr/14/21.190.md), [§ 21.191(k)](/cfr/14/21.191.md?p=k), or [§ 21.191(l)](/cfr/14/21.191.md?p=l) of this chapter that do not conform to a type certificate.
- (b) **Compliance requirements.** A person seeking to comply with this part for an aircraft described in [paragraph (a)](#a) of this section must meet one of the following requirements.
  - (1) **Use of a noise consensus standard.** An aircraft described in [paragraph (a)](#a) of this section may demonstrate compliance using a noise consensus standard that meets the following conditions:
    - (i) The noise consensus standard has been approved by the FAA; and
    - (ii) **The noise consensus standard has been determined by the FAA to be appropriate for the aircraft.**
  - (2) **Use of noise procedures available for type certificated aircraft.** An aircraft described in [paragraph (a)](#a) of this section may demonstrate compliance through the procedures available for type certificated aircraft, including:
    - (i) A demonstration that the applicable noise limits specified in this part are not exceeded for any configuration, flight profile, or reference condition required for an aircraft to demonstrate compliance; and,
    - (ii) When applicable, a demonstration that any test procedures and analyses contained in a related appendix to this part have been met for any configuration, flight profile, or reference condition required.
  - (3) **Use of alternative means of compliance.** An aircraft described in [paragraph (a)](#a) of this section may demonstrate compliance through one of these alternative means:
    - (i) **Aircraft similar to a type-certificated aircraft.** An aircraft that is determined by the FAA for noise purposes to be the same as or sufficiently similar in design to a type certificated aircraft described in [§ 36.1](/cfr/14/36.1.md) may demonstrate compliance with this part by:
      - (A) Using the same testing requirements as the type certificated aircraft that FAA has determined for noise purposes is the same or sufficiently similar in design to the aircraft for which a person seeks to show compliance with this part; or
      - (B) Adopting the noise levels of the type certificated aircraft that FAA has determined for noise purposes is the same or sufficiently similar in design.
    - (ii) **Aircraft with no similar type-certificated aircraft.** A person may demonstrate compliance with this part using the noise requirements determined by the FAA to be appropriate for the aircraft.
- (c) **Statement of compliance.** Persons seeking to show compliance with this part must meet the requirements of [paragraph (b)](#b) of this section and must submit a statement of compliance to the agency.
  - (1) **The statement of compliance must—**
    - (i) State that the aircraft has demonstrated compliance with the applicable provisions of this part;
    - (ii) Include the noise levels of the aircraft, and procedures, aircraft configurations, aircraft weights, and other information employed for obtaining the demonstrated noise levels; and
    - (iii) **Include the following statement—** “No determination has been made by the Federal Aviation Administration whether the noise levels of this aircraft are or should be acceptable or unacceptable for operation in any location.”
  - (2) After stating compliance with the part per [paragraph (c)(1)](#c-1) of this section, any subsequent alteration of the aircraft that increases noise would render invalid any previous statement of compliance to this part for that aircraft.
