Canadian Aviation Regulations (SOR/96-433)

521.159 (1) Subject to subsection (2), an applicant for the approval of a change to the type design of an aeronautical product that results in a change in the noise levels of an aircraft shall demonstrate

• (a) that the aircraft meets the noise standards specified in Subchapter A of Chapter 516 — Aircraft Emissions of the Airworthiness Manual; or

• (b) that the aircraft continues to meet the noise standards that applied before the change was undertaken and that are recorded in the type certificate data sheets or in a document that has been accepted by the Minister as being equivalent to a type certificate for that aircraft.

(2) Subsection (1) does not apply in respect of

• (a) a restricted category aircraft for use in agricultural operations or fire prevention and suppression;

• (b) the installation or removal of floats or skis;

• (c) the installation or removal of external equipment on a rotorcraft; or

• (d) an aircraft whose certification basis does not contain noise standards, if the change to the type design does not involve

  • (i) a change in the number or type of propellers,

  • (ii) a change in the number of engines or in the principle of propulsion of the engines, or

  • (iii) in the case of a rotorcraft, a change in the number of rotors or in the principle of operation of the rotors.

(3) An applicant for the approval of a change to the type design of a turbine-powered aircraft shall demonstrate that the aircraft meets the standards respecting the prevention of intentional fuel venting specified in Subchapter B of Chapter 516 — Aircraft Emissions of the Airworthiness Manual.

(4) An applicant for the approval of a change to the type design of an aircraft engine shall demonstrate that the aircraft engine meets the smoke and gaseous aircraft emissions standards specified in Subchapter B of Chapter 516 — Aircraft Emissions of the Airworthiness Manual.

521.160 (1) An applicant for the approval of a change to the type design of an aeronautical product shall

• (a) demonstrate to the Minister that the product conforms to the certification basis established by the Minister under section 521.157 by conducting the inspections and tests referred to in section 521.44;

• (b) submit to the Minister a declaration attesting to the demonstration of conformity of the product with its certification basis;

• (c) make available to the Minister the means by which conformity is established;

• (d) in the case of an aircraft, record the noise levels in its flight manual or in a supplement to that manual using the Guidelines for the Administration of Noise Certification Documentation set out in Attachment G of Annex 16, Volume I to the Convention;

• (e) submit a signed undertaking to carry out the responsibilities specified in Division VIII; and

• (f) submit to the Minister for approval any manual, instructions and limitations that are required by the certification basis established in respect of the product.

(2) An applicant for the approval of a change to the type design of an aeronautical product other than a restricted category aircraft shall demonstrate to the Minister that

• (a) in the case of an aircraft, no feature or characteristic makes the aircraft unsafe, taking into account the category in which certification is requested; and

• (b) the type design of the product provides a level of safety at least equivalent to that provided by the certification basis that applied before the change was undertaken.

(3) An applicant for the approval of a change to the type design of a restricted category aircraft shall demonstrate to the Minister that

• (a) no feature or characteristic makes the aircraft unsafe when that aircraft is operated within the limitations specified for its intended use; and

• (b) the aircraft has a type design that conforms to its certification basis.
