Release of Technical Airworthiness Manual (TAM) Change 8

Reference: Technical Airworthiness Manual, C‑05‑005‑001/AG-001, Change 8, dated 2019-04-01

  1. The purpose of this letter is to formally announce the release of Change 8 to C‑05‑005‑001/AG-001, Technical Airworthiness Manual (TAM).
  2. TAM Change 8 is available on the Technical Airworthiness Authority (TAA) internet site. In addition, organizations with access to the Defence Wide Area Network can access TAM Change 8 at the Technical Airworthiness Manual page, or on the Canadian Forces Publication Depot’s intranet site. Amendments to the Canadian Forces Technical Orders (CFTO) C-05-005-P02/AM-001 to C‑05-005-P12/AM-001 (P-Series) covering RCAF maintenance policy requirements resulting from the Change 8 of the TAM are complete.
  3. TAM Change 8 introduces new continuing airworthiness requirements that have already been communicated to affected stakeholders through the Notice of Proposed Change (NPC) process.  In addition to minor and editorial changes meant to enhance format and readability, and improve the implementation of the Technical Airworthiness Program, there are other more substantive changes that are introduced that did not require consultation through the NPC process; for example: introduction of initial type certification requirements for Unmanned Aircraft Systems (UAS). A summary of the composition of TAM Change 8 is attached as Annex A.
  4. As TAM Change 8 will affect stakeholders differently, the TAA, through the Director Technical Airworthiness and Engineering Support (DTAES) regulatory staff, will coordinate directly with accredited recognized organizations, as well as the project management offices, to provide guidance and direction with regard to compliance requirements affecting organizational approvals.
  5. In the interim, if you have any questions or feedback related to the content of the new or amended provisions of TAM Change 8, you may contact the TAA Secretariat, at:

    Directorate of Technical Airworthiness and Engineering Support (DTAES)
    National Defence Headquarters

  6. The evolution and update of the TAM is an ongoing process and my staff is continuously working to further develop and improve its content and efficacy. We will continue to use NPCs to seek your feedback regarding future changes and welcome your participation and input in the TAM amendment process.

Sincerely,
André Pelchat
