Annex B: Example of appendix to SOW or PWS related to decisions of significance

This annex provides examples of a "Decisions of Significance/Airworthiness Scope and Depth of Authority" document, which is typically included as an appendix to the SOW or PWS. These examples include only the applicable airworthiness requirements. PMO and WSM staff must add any other requirements deemed necessary.

Decisions of Significance/Airworthiness Authorities

1. Introduction

1.1. The accomplishment of all decisions associated with work on the <Insert Contract #> will be split between the Contractor and Canada. Canada will retain the Decisions of Significance listed in this Appendix, unless otherwise stated in the SOW. Decisions of Significance fall into the following categories:

1. Decisions impacting operations;
2. Decisions having a financial impact on Canada; and
3. Decisions affecting airworthiness.

1.2. The following sections are to be read in conjunction with Table 1 – Airworthiness Authority.

2. Decisions Impacting Operations

2.1. Decisions that impact operations include:

1. Approval of changes to third line schedules (duration and induction dates);
2. Issue of Special Inspections;
3. Issue of Design Changes affecting the physical configuration of the aircraft;
4. Conduct of Mobile Repair Parties;
5. The grounding and operational restricting of aircraft;
6. Changes that:
   1. significantly increase Canada’s maintenance burden, whereby the level of effort involved is perceived as being beyond the maintenance unit’s capability and will require augmentation to DND-provided resources;
   2. affect the aircraft operating procedures; or
   3. significantly impact the Training System, whereby the level of effort involved is perceived as being beyond the training unit’s capability and will require augmentation to DND-provided resources.

2.2. For clarification, the Contractor may approve alternative parts that are identical, or nearly identical, replacements for the existing parts described in the Canada approved maintenance program, which conform to the following requirements that are excluded from item 2.1.c above:

1. The part does not introduce any new capabilities that would affect the way that the aircraft currently operates, which would result in a Major design change;
2. The aeronautical product on which the part will be installed does not require modification; and
3. There is no requirement to amend maintenance procedures, maintenance schedules, the flight manual or the aircraft operating instructions in order to accommodate the new part.

3. Decisions Having a Financial Impact on Canada

3.1. Canada will retain decisions for any changes to In-Service Support that have a financial impact upon Canada.

3.2. Canada will retain all decisions on the repair or replacement of components due to non-inherent failure damage.

4. Decisions Affecting Airworthiness

4.1. Canada will retain airworthiness decisions for which the Contractor has not been delegated the requisite authority from the Technical Airworthiness Authority (TAA).

4.2. The TAA, having satisfaction of the Contractor’s conformance to the DND/CAF Airworthiness Program, grants sufficient authority to the Contractor to permit completion of all assigned work in accordance with Table 1. Canada will retain airworthiness authority in accordance with the limitations identified in Table 1.

Note:
The formal assignment of airworthiness authority to the applicable Contractor organization is effected through the approval by the TAA of the applicable Contractor’s Airworthiness Process Manual or DND Airworthiness Supplement, in accordance with TAM Part 1, Chapter 4.

4.3. The DND Type Certificate Holder (TCH) or the TAA will retain fleet level airworthiness authorities within the construct of the Design Support Network (DSN) and any Airworthiness authority not assigned to the Contractor.

4.4. Although the Contractor will be permitted to make the airworthiness decision for which he possesses the requisite authority, if that decision results in an impact to operations, or has a financial impact on Canada, the resultant Business Decision will be made by Canada.
