Canadian Aviation Regulations

511.06 (1) Unless the applicant demonstrates, at the time of submitting an application for a type certificate or a change to a type certificate in respect of an aeronautical product, that the aeronautical product requires a longer period for design, development and testing — and for that reason the Minister approves a longer period — the application is effective during one of the following periods, starting on the date of application:

• (a) five years for a transport category aeroplane certified under Chapter 525 of the Airworthiness Manual or a transport category rotorcraft certified under Chapter 529 of the Airworthiness Manual;

• (b) three years for an aircraft other than an aircraft referred to in paragraph (a);

• (c) three years for an aircraft engine, an aircraft propeller or a turbine-powered APU; and

• (d) two years for an aircraft appliance other than a turbine-powered APU.

(2) If a type certificate will not be issued or a change to a type certificate will not be approved within the period established in accordance with subsection (1), the applicant may

• (a) submit a new application; or

• (b) apply for an extension of the effective period of the original application.
