Chapter 5. Airworthiness Control Procedures
5.5 Approval Certificate Completion
5.5.1 Approval Certificates
LSTC, STC and RDC approval certificates specified in AWM Chapter 513 should be used by Delegates for all modifications and repairs not covered by a TC. The certificates used should be those provided by the regional offices in paper or electronic format, or if developed by the Delegate the certificate must be indistinguishable from a certificate issued by TCCA. Electronic templates provided by TCCA, or certificate photocopies may be used to generate certificates.
5.5.2 Certificate/Form Completion
AWM Chapter 513 certificates must be completed in accordance with the repair design approval procedures presented in ACSI 22. The certificate must contain a red wafer which has been embossed with the TCCA seal. Delegates may obtain the die for the TCCA seal from:
465 Gladstone Avenue
phone (613) 236-0677
fax (613) 236-3508
For ease of ordering, the die is referred to as the standard TCCA seal and has been given part number 1004-3 by Capital Stamp. The format for the seal is as indicated below.
220.127.116.11 TCCA AE-100 Form, Statement of Compliance
Copies of properly completed AE-100 Statement(s) of Compliance should be submitted for each approval project. The form should clearly indicate:
the Delegate functional specialty and Delegate number;
the project approval number;
each relevant test report number, title and the applicable airworthiness requirements for which a finding of compliance is being made or recommended; and
- signature indicating Delegate approval or recommendation for approval.
The following material on the TCCA AE-100 Form may change based on the outcome of the AWM Chapter 513 Certificate and Statement of Compliance form Working Group review findings.
The Delegate's only means of providing a statement of compliance for technical data is through the use of the TCCA AE-100 Form. The AE-100 Form is to be used only for the provision of a statement of compliance and not as an approval document in place of an AWM Chapter 513 certificate. N-AME-AO 45/68 was the original TCCA policy document that permitted delegates to use an AE-100 form as a means of recording a design approval, in conjunction with making a statement of compliance. Currently, AMA 505C/1 states that the AE-100 form may be used as "an instrument of design approval as well as indicating compliance" providing certain criteria are met. When AWM 513 was originally promulgated it was intended to replace this practice by requiring the issue of an approval certificate, i.e., L/STC or RDC in accordance with AWM 513 criteria. A Repair Design Certificate or Limited Supplemental Type Certificate must be issued for approvals processed in accordance with AWM 513 and utilizing approval numbers issued by the responsible region. Consequently, the use of an AE-100 form as a means of recording an AWM Chapter 513 approval is to be discontinued.
The AE-100 form may still be used by delegates to make the necessary statement of compliance and/or recommendation to a region for the issue of the required STC, L/STC or RDC certificate for which a delegate may not hold the required delegation.
An example of the current AE-100 Form is found in Appendix 2 of AMA 505C/1, and the following bullets highlight information to be included on the form.
The date entered in the date box in the upper right corner of the form is the date the Delegate made the finding that the listed data complied with the applicable requirements.
In the "List of Approved Reports and Data" block, the Delegate must indicate exactly the extent of the approval. The Delegate must reference all data covered by the approval: drawing numbers with change letters, report numbers with revision levels, and dates, etc.
Indicate any data that the Delegate cannot or chooses not to approve by a separate listing with the notation: "TCCA APPROVAL REQUIRED." If such listing of unapproved data is very voluminous, then a statement clearly indicating the extent of approval or non-approval is sufficient, e.g., "Structural Aspects Approved Only -- No Approval of Electrical Data" or similar statements.
Approve/Recommend Approval of these Data
The use of "Approve" on the TCCA AE-100 Form can only be done by those Delegates whose letter of authorization indicate that they have the appropriate scope to make the finding. When a Delegate has the authority to "approve" but only "recommends approval," the Delegate must explain, in writing, why the data was not approved.
In the "Requirements and Status" block of the TCCA AE-100 Form, the Delegate shall list all applicable regulations and identify by paragraph and subparagraph. If the list is too long to be included on TCCA Form AE-100, additional sheets or an attachment of the certification basis/GCP may be included.
It must be clear from the list the exact regulation(s) paragraphs, subparagraphs, or other appropriate airworthiness requirements with which the data comply. Merely indicating "structural regulations" or other generalizations is insufficient.
The Delegate's signature, typed or printed name and identification number in the "Certification" block of the TCCA AE-100 Form constitutes the Delegate's approval of the technical data.
The following notes apply to the AE-100 Form:
Certification Activities. The Delegate will send copies of all TCCA AE-100 Forms to the project manager at TCCA.
Maintaining File. The applicant is responsible for maintaining a file containing copies of all TCCA AE-100 Forms submitted to TCCA and any associated data.
Omissions and Errors. Careful preparation and use of TCCA AE-100 Form is important. As omissions and errors in approvals can cause delays in certification programs. Some of the more common omissions and errors are:
- Failure to sign form;
- Failure to include revision levels or dates with the drawing numbers, reports, etc., listed;
- Failure to include drawings or drawing lists on TCCA Form AE-100 as a listing of the drawings approved;
- Failure to specify those portions of the data approved, and those portions of the data that TCCA must evaluate;
- Failure to check the "recommend" or "approve" box;
- Failure to submit the original TCCA Form AE-100 to the project manager;
- Failure to reference specific REGULATION(S) sections in the "Requirements and Status" block;
- Failure to approve data only within the Delegate's delegated functions and authorized areas.
- Failure to properly identify the make of the aircraft as it relates to the existing TC holder; i.e. for restricted category aircraft, the Delegate should not list the original manufacturer's name.
18.104.22.168 STC Approval Document
The issue of an STC (Form #26-0357) signifies that the technical design data for a modification or repair is approved and the certificate forms part of the aeronautical product type design, when the subject design change is incorporated.
22.214.171.124 LSTC Approval Document
The issue of an LSTC (Form #26-0432) signifies that the technical design data for a modification or repair is approved and the certificate forms part of the aeronautical product type design, when the subject design change is incorporated. Where the modification is intended for incorporation in a limited number of products of a type as opposed to all products of a type, the approval document is known as a LSTC. In this regard the term "limited" refers only to the limitation with respect to the serial numbers to which the approval applies, and does not signify an operating "restriction" on the modified product.
126.96.36.199 RDC Approval Document
The issue of an RDC (Form #26-0457) signifies that the technical design data for a repair is approved and the certificate forms part of the aeronautical product type design, when the subject design change is incorporated. An RDC may be issued to record the approval of process repair schemes that are alternate to those repair schemes developed by the manufacturer of the aeronautical product for the purpose of component overhaul or repeated repairs.
