What is true if the proposed alteration of an aircraft does not conflict with previous modifications?

If the proposed alteration of an aircraft does not conflict with previous modifications, it can be concluded that the data could be used without further approval. This is based on the understanding that the FAA allows for the use of previously approved data as long as the current modification aligns with the specifications and conditions set forth in those prior approvals.

When an alteration is consistent with existing modifications, it indicates that the FAA has already deemed the previous modifications acceptable and that they do not adversely affect the safety or operation of the aircraft. Therefore, the new alteration can be considered safe and implementable under the existing guidelines, leading to a streamlined process in which additional approval is unnecessary.

In scenarios where changes are proposed that conflict with prior modifications, different regulations and requirements would apply, necessitating further review and potentially new approval.
