The process for changes and modifications to the Aircraft is approved through which process?

• A. Safety Review Board
• B. ACCB process
• C. Engineering Change Proposal
• D. QA Review

Answer: (B)

In aviation maintenance, any change or modification to an aircraft must go through a formal change-control process to protect airworthiness and keep configuration records accurate. The ACCB process is the designated authority for approving such changes. It reviews the proposed modification, usually documented as an Engineering Change Proposal, and evaluates safety implications, interoperability with existing systems, regulatory compliance, and the impact on maintenance and operations. Only after ACCB approves the change can it be implemented and the aircraft’s records updated. Other checks like safety reviews or QA reviews support the process, but ACCB is the final approval authority for changes and modifications.
