What indicates the approval of non-previously approved data in FAA Form 337?

The approval of non-previously approved data in FAA Form 337 is indicated by the approval statement and signature in item 3. This item specifically requires the authorized individual to provide a declaration that the documented alterations or repairs comply with applicable standards and regulations. By signing this item, the authorized person validates that the changes made are appropriate and within regulatory compliance.

This process is crucial for maintaining the airworthiness of aircraft, as Form 337 is essential for documenting major repairs or alterations that need regulatory approval. The signature serves as confirmation that the submitted information has been reviewed and is acceptable under FAA regulations.

While other items on the form have their specific roles, item 3 is particularly focused on the explicit approval of the data in relation to alterations or repairs, making it the correct indicator of that approval.
