(ii) rotorcraft of 3 175 kg MTOM or less;

(iii) sailplanes, powered sailplanes, balloons and airships, as defined in ILA1 or ILA2,

2. that follow design data included in certification specifications issued by the CAOIRI , containing acceptable methods, techniques and practices for carrying out and identifying standard changes, including the associated instructions for continuing airworthiness; and

3. that are not in conflict with TC holders data.

(b) Points 21.A.91 to 21.A.109 are not applicable to standard changes.

نکته:

موارد 91 تا 109 در مورد TC قابل انطباق نمی باشد.

تعریف تغییر Minor :

A ‘minor change’ is one that has no appreciable effect on the mass, balance, structural strength, reliability, operational characteristics, noise, fuel venting, exhaust emission, operational suitability data or other characteristics affecting the airworthiness of the product.

Without prejudice to 21.A.19, all other changes are ‘major changes’ under this Subpart.

بدون توجه به مفاد بند 21.a.19  هر گونه تغییر دیگری ، از نوع Major خواهد بود.

Major and minor changes shall be approved in accordance with 21.A.95 or 21.A.97 as appropriate, and shall be adequately identified.

1. A change that the CAOIRI finds not to be significant. 

تغییری که به نظر سازمان هواپیمایی کشوری مهم نمی باشد 

In determining whether a specific change is significant, the CAOIRI considers the change in context with all previous relevant design changes and all related revisions to the applicable certification specifications incorporated in the type-certificate for the product.

 Changes that meet one of the following criteria are automatically considered significant: 

هر تغییری که یکی ازموارد زیر را در بر بگیرد از نوع مهم(Significant) خواهد بود :

(i) The general configuration or the principles of construction are not retained.

 (ii) The assumptions used for certification of the product to be changed do not remain valid.
