| Step 1: Identify the proposed type design changes to the aeronautical product. (See paragraph 3.2 of GM 21.A.101) | The proposed type design changes are identified here or in the following document(s): Click here to enter text. | ||||||||
| Note: The CRI process is used to track/document the decisions at Step 2 and Steps 5 through 8 as required. | |||||||||
| Step 2: Is the proposed type design change substantial? (See paragraph 3.3 of GM 21.A.101) | ☐ Yes | New Type Certificate: Proceed to point 21.A.19. Point 21.A.101 does not apply. A Certification Review Item CRI A-01 will be used to establish and document the certification basis. | |||||||
| ☐ No | Proceed to Step 3. | ||||||||
| Step 3: Will you use the latest standards? (See paragraph 3.4 of GM 21.A.101) | ☐ Yes | Latest Standards: Propose a certification basis using the CSs in effect at the date of application. Proceed to Step 8. | |||||||
| ☐ No | Proceed to Step 4. | ||||||||
| Step 4: Arrange changes into related and unrelated groups. (See paragraph 3.5 of GM 21.A.101) | Note: For multiple groupings, continuation of this process should be split into separate decision records. Groupings may be rationalised and recorded in separate documents: Click here to enter text. | ||||||||
| Step 5: Is each related or unrelated group a significant change? (See paragraph 3.6 of GM 21.A.101) | ☐ Yes | Proceed to Step 6. | |||||||
| ☐ No | Earlier Standards: Propose a certification basis using the CSs in effect before the date of application but not earlier than the existing certification basis. Certification basis to be defined and documented as indicated (below). Proceed to Step 8. | ||||||||

| Step 7: Do the latest standards contribute materially to the level of safety and are they practical? (See paragraph 3.10 of GM 21.A.101) | ☐ Yes | Latest Standards: Propose a certification basis using the CSs in effect on the date of application. | |||||||
| ☐ No | Earlier Standards: You may propose a certification basis using the CSs in effect before the date of application but not earlier than the existing certification basis. Certification basis defined or documented as indicated below. | ||||||||
| ☐ Continuation Sheet(s) Attached | Note: Several CSs may apply to each affected area, and the assessment may differ from specifications to specifications. Indicate ‘Yes’ if compliance with any latest standard(s) is required. Indicate ‘No’ only if earlier standard(s) is (are) proposed. | ||||||||
| Note: | You may submit a proposal for the decision in Step 7; however, EASA will make the final certification basis determination. | ||||||||
| Step 8: Ensure the proposed certification basis is adequate. (See paragraph 3.11 of GM 21.A.101) | If you deem that the certification basis is adequate, submit the proposed certification basis to EASA. If not, consult EASA. CRI A-01 may be needed to document the certification basis. | ||||||||
| Certification Basis: | The certification basis is detailed here or in the following document(s): Click here to enter text. | ||||||||
| Based on the information provided above, I am proposing the certification basis with the following classification for the type design change. (check one) | |||||||||
| ☐ Significant, pursuant to point 21.A.101. | ☐ Not significant, pursuant to point 21.A.101. | ||||||||
