Request an Alternative Means of Compliance or exemption to an Airworthiness Directive

Before you apply

  • anyone can apply for an AMOC with an Airworthiness Directive (AD) or an exemption to AD
  • if you’re not sure if you need an AMOC or exemption, contact the Continuing Airworthiness division
  • if you apply for an AMOC, it will be issued to only you unless you ask that a third-party to be the holder

Applying for any type of AMOC or exemption

Your application must have enough information to clearly identify which products will and will not be subject to the AMOC and/or exemption.

Your application should include:

  • the product type
  • make and model designation
  • serial number(s) and registration marks (in some cases)
  • the engine or the propeller serial number or both, if applicable
  • the type of AMOC you’re applying for, if applicable
  • the aircraft owner’s full name, or the full name of the person who’s applying on behalf of the owner
  • your contact information, or contact information for the person who’s applying on behalf of the aircraft’s owner
  • the Airworthiness Directive (AD) number and the specific requirements that are affected by your application
  • a detailed description of your alternative means of complying with the Airworthiness Directive (AD) exemption, including illustrations or other supporting documents
  • your ideal decision deadline (optional)
  • an explanation of why you need an AMOC or exemption

Applying for a Global or Blanket AMOC

Registration numbers and individual serial numbers are optional for Global or Blanket AMOCs. Including a range of affected serial numbers or a statement like “all Canadian-registered products” may be enough information.

Your application should also explain how we should describe the AMOC corrective actions to protect your proprietary information. We will send these types of AMOC approvals to both you and any other affected owners, operators and/or foreign Civil Aviation Authorities.

Applying for a Specific AMOC

If your application is for a ferry flight type of Specific AMOC, it should include:

  • the current location of the affected product and the destination of the ferry flight
  • the expected number of flight hours and flight cycles that you will need to complete the ferry flight
  • the number of calendar days it will take you to complete the ferry flight. This timeline should begin on the day you receive your AMOC and end once the ferry flight is complete
  • list of all corrective actions that are past due and any mitigating inspections, functional checks or other actions that you want to complete before the ferry flight
  • list of operational restrictions that will be applied to the ferry flight to limit risk. Examples of standard ferry flight operational restrictions:
    • only essential crew allowed on board
    • the flight is non-pressurized, not flown over water and limited to day VFR (visual flight rules)
    • the flight will be done with the landing gear locked in the down position
    • the flight won’t occur over populated areas
  • proof that the proposed corrective actions and any other limits will maintain the level of safety similar to the one from the Airworthiness Directive (AD)

If your application for an AMOC is related to a change to the type design:

  • include details of the design change and the contact information for the Transport Canada personnel who are assigned to the design change project
  • changes to the type designed must be approved separately from your AMOC. The usual certification procedures of Part V of the CARs still apply
