Chapter 8 Technical Standard Order Authorizations
Article 58
To produce aviation products, appliances and parts according to the airworthiness requirements of Technical Standard Order, the manufacturer shall submit an application for a Technical Standard Order Authorization (TSOA). An applicant is entitled to a TSOA Certificate (see Attachment 19) if its product is properly certified by CAA. The applicant shall submit to CAA the following:
1) The TSOA application form (see Attachment 20).
2) A document describing its organization, manufacturing facilities and locations.
3) A statement of conformance certifying that the applicant has met the requirements of this chapter and that the article concerned meets the applicable TSO that is effective on the date of application for that article. Each manufacturer who requests approval to deviate from any performance standard of a TSO shall submit to the CAA the application together with the request for approval to deviate, and show that the standards from which a deviation is requested are compensated for by factors or design features providing an equivalent level of safety.
4) One copy of the technical data required in the applicable TSO.
5) A quality manual in compliance with Attachment 9 of Article 29 to the CAA for approval. In complying with this section, the applicant may refer to current CAA approved quality manual as part of a previous TSOA application.
Article 59
After receiving the application and other documents required by Article 58 of this section to substantiate compliance with this chapter, and after a determination has been made of its ability to produce duplicate articles under the quality system complying with Article 29, the CAA issues a TSO authorization (including all TSO deviations granted) to the applicant to identify the article with the applicable TSO marking.
A Technical Standard Order Authorization is not transferable.
Article 60
Each manufacturer of an article for which a TSOA has been issued shall-
1) Manufacture the article in accordance with this chapter and the applicable TSO.
2) Conduct all required tests, inspections and maintain a quality system adequate to ensure that the article meets the requirements of paragraph (1) of this section and is in condition for safe operation.
The holder of a TSOA must notify the CAA in writing within 10 days, of any change to the quality system and the change that may affect the inspection, conformity, or airworthiness of its product. The TSOA holder must obtain CAA approval before making any changes to the location of any of its manufacturing facilities.
Article 61
TSOA holders shall apply to CAA for authorized release certificate for installation on the on applicable type certificated products, following the completion of procedures contained in Attachment 17. The CAA will issue an authorized release certificate when all procedures are satisfactorily completed on that TSO product.
Identify any portion of the TSO article that leave the TSOA holder's facility as CAA approved with the manufacturer's part number and name, trademark, symbol, or other CAA approved manufacturer's identification.
Article 62
The design changes by the TSOA holder are defined as following-
1) Minor changes by the manufacturer holding a TSO authorization: Any design change other than a major change is a minor change.
2) Major changes by the manufacturer holding a TSO authorization: Any design change by the manufacturer extensive enough to require a substantially complete investigation to determine compliance with a TSO is a major change.
The manufacturer of an article under a TSOA may make minor design changes without further approval by the CAA. In this case, the changed article keeps the original model number (part numbers may be used to identify minor changes) and the manufacturer shall forward to the CAA any revised data that are necessary for compliance with the requirement of this chapter.
Before making a major change, the manufacturer must assign a new type or model designation to the article and apply for an authorization under Article 58.
Article 63
Each manufacturer holding a TSOA shall, for each article manufactured under that authorization, keep the following records at its factory:
1) A complete and current technical data file for each type or model article including design drawings and specifications;
2) Complete and current inspection records showing that all inspections and tests required to ensure compliance with Article 60 paragraph (2) of this chapter have been properly completed and documented.
The TSOA holder shall retain the records described in above paragraph until it no longer manufactures the article. When the article is no longer manufactured, copies of these records shall be sent to CAA.
Article 64
Each manufacturer holding a TSOA shall permanently and legibly mark his article with applicable TSO numbers. The CAA may withdraw the TSOA when the product marked as a TSO does not meet the performance standards of the applicable TSO.
Article 65
No person may import a TSO article for civil aviation use unless properly certificated. The holder of the TSO article shall use the procedures in Attachment 18 for the validation of imported TSO articles, unless otherwise prescribed in a treaty or an agreement.
Airworthiness approvals that were issued by the airworthiness authority of the exporting country shall be attached with the imported TSO articles.
