Appendix D - Sample Engineering Procedures Manual

Section 3:  Scope of Authority
3.1  DAR Authorized Functions

I, Robert Smythe, am authorized by the Minister of Transport to perform the functions of a DAR in the functional specialty of Structures (Loads and Airframe Stress). This authorization is granted by the TCCA letter dated January 10, 1999 which is reproduced in Appendix D, and through the granting of the Delegation of Authority certificate shown on page iv. I will accomplish the delegated functions in accordance with the information contained in this EPM and the TCCA letter of authorization.

Within the scope of authorization and subject to the functions, responsibilities and authorizations identified in this section, I will participate in design approval activities leading to the issuance of RDC's, LSTC's, and STC's in the capacity of a DAR in the Structures Specialty. My scope of delegation is applicable to those aeronautical products that are certified to CAR Part V, Subpart 25, or equivalent, for Transport Category Aeroplanes.

I, Robert Smythe, may perform the airworthiness engineering functions contained in this EPM. The following privileges may be exercised in the specialty of Structures, subject to limitations defined in the TCCA letter of authorization seen in Appendix D, and defined in Section 3.2:

  1. Approval of technical data only in support of making a statement of compliance for the delegated standards of airworthiness; including:
    1. engineering reports;
    2. engineering drawings;
    3. configuration drawings and instructions;
    4. drawing lists;
    5. Instructions for Continued Airworthiness, i.e., against AWM section 525.1529 but not the ICA's themselves which are accepted (except Airworthiness limitations which are not delegated); and
    6. other engineering data relating to structural applications;
    1. Making a recommendation to TCCA using the Statement of Compliance form for non-delegated engineering data;
    2. Issuance of RDC and LSTC approval documents; and
    3. Make a determination that a change to the type design is significant or not-significant in accordance with subsection 511.13 or paragraph 513.07(3) of the CARs and document that determination using the Changed Product Rule (CPR) Decision Record form shown in Appendix B of TP 12995. AMA 500/16, PL 500-002 and the soon to be published SI 500-003 will be used to make this determination.

    The delegated functions and authorized areas for which findings of compliance may be made are identified in the Functional Matrix and Specialty Delegation Matrix provided in Appendices B and C respectively.

    3.2  Limitations

    The general limitations identified in chapter 3.5 of the Delegations Handbook for Designated Engineers and Design Approval Representatives apply to the extent and exercise of my delegated authority. In addition, the following specific limitations apply:

    1. Only those delegated functions in the authorized area defined in this EPM and the TCCA letter of authorization may be exercised;
    2. The delegated privileges are not transferable and cannot be further delegated;
    3. Items in the Structures specialty that are not delegated and will require TCCA approval, including:
      1. Basic loads (except loads whose magnitude is defined in the airworthiness standards such as emergency landing inertia loads)
      2. Fatigue and Damage Tolerance Items;
      3. Flutter and Aeroelastic Methods;
      4. Discrete Source Damage (such as Bird Impact, Rotor Burst);
      5. Ditching;
      6. Airworthiness Certification Test Programs; and
      7. Composite Material;
    1. New Airworthiness Requirements and Standards introduced subsequent to the appointment shall be reviewed with TCCA with respect to their applicability to the delegate's scope of delegation. A new authorization letter may be required; and
    2. Required to advise TCCA when the exercise of this delegation requires a failure mode and effects analysis having a significant impact on Airworthiness. AWM section 525.1309 is not delegated for essential and critical systems.
    3.3  Overlapping Responsibilities

    For projects and requirements where a clear division of responsibility is not possible resulting in an overlap of functions between specialties (e.g. Test Pilot, Flight Analyst, structures, powerplants, mechanical systems, avionics and electrical systems), I will only be responsible for the Structural aspects of an approval, i.e.:

    1. Structures and Powerplant - responsible for the structural aspects of the powerplant installation only;
    2. Mechanical, Hydraulic, Avionics and Electrical Systems - responsible for the structural aspects only of these systems including their installation;
    3. Flight Test - responsible for the structural aspects only of Flight Test;
    4. Heating, Ventilation and Pressurization - responsible for the structural aspects only of these systems;
    5. Fire Protection - responsible for the structural aspects of the fire protection including possible fire damage powerplant fires may cause to the other aircraft structures and structural damage by exposure to the heat of other fires; and
    6. Miscellaneous Components - responsible for the structural aspects of the fuel tanks.
    3.4  Change to Authorization

    I acknowledge that TCCA retains the right to either increase, decrease, or remove the level of delegation granted to me, and that these changes will be in accordance with the guidance in chapter 3.6 of the Delegations Handbook for Designated Engineers and Design Approval Representatives. Any change to my authorized scope will result in a revision to this EPM, which will be submitted to TCCA within 20 working days of receipt of written change notification.

    3.5  Duration of Authorization

    I understand that this authorization will remain in effect until withdrawn subject to the conditions in chapter 3.6.4 of the Delegations Handbook for Designated Engineers and Design Approval Representatives.
