    • (a) Not applicable


  • (1) Improvements to the airfield components typically involve long lead times and, are complex in nature due to the regulatory requirements, sometimes from other authorities and the resulting impact on its operation during execution of the works.  These lead times, typically extend 12 – 24 months and sometimes longer, due to multiple steps in the process, such as tendering or various agency approvals, prior to the execution of the works.  Also, the execution stage of some projects may extend over multiples seasons due to the nature of the works and environmental conditions.
  • (2) CAR 302.07 (1)(a)(ii) requires the operator of an airport to comply “…with the standards set out in the aerodrome standards and recommended practices publications, as they read on the date on which the part or facility was returned to service,…”
  • (3) The introduction of TP312 5th edition presents an additional consideration for airport operators that are currently in the advanced planning, or execution phases of capital works. Considering the lead time related to project planning and execution, the airport operator needs to have knowledge of which set of “standards’ the airport will be subject to upon its return to service early in the planning process.
  • (4) In considering the above, TCCA has issued a National regulatory exemption to 302.07(1)(a)(ii) so that the airport may use the standards contained in TP312 4th edition, subject to certain conditions.


  • (1) The airport operator shall submit to the Transport Canada Civil Aviation regional office personnel a plan of airport construction and operations no later than 12 months (calendar days) after the coming into force of  TP312 (5th edition).  Elements to be included in the submission are, but not limited to;
    • (a) Identification of the airport work areas subject to the exemption;

    • (c) Construction schedule (See 3 below); and
    • (d) Plan of airport operations detailing how the ongoing airport operations will be maintained in compliance with the requirements of the Canadian Aviation Regulations while the works are in progress.

  • (3) Works must be completed in full and the airport areas subject to the exemption be fully operational within 24 months (calendar days) after the coming into force of TP312 (5th edition) standards;
  • (4) The Airport Operations Manual must clearly state which infrastructure elements of the airport are being exempted from TP312 (5th edition) for conformance to TP312 (4th edition) standards;
  • (5) A copy of the Exemption, including its’ signed attachment must be included in the Airport Operations Manual;
