What type of modification must be authorized before making repairs on reduction gear systems?

• A. Technical Directive
• B. Maintenance Instruction
• C. Modification Work Order
• D. Repair Approval Form

Answer: (A)

The correct choice is the Technical Directive, as this type of modification is essential to authorize changes or repairs on reduction gear systems. Technical Directives provide official guidance and instructions that ensure any maintenance performed, including repairs on reduction gear systems, complies with established standards and protocols. This ensures safety, reliability, and consistency in the maintenance practices across the fleet. Technical Directives are critical because they contain specific procedures, parts requirements, and operational considerations that must be followed closely during the repair process. They help prevent issues that could arise from unauthorized or undocumented modifications, which could compromise the integrity of the reduction gear system. The other types of documentation, while important in their own contexts, do not serve the same formal purpose as a Technical Directive. Maintenance Instructions generally provide guidance on routine upkeep but may lack the authorization for modifications. Modification Work Orders refer to planned changes but may not always apply specifically to repair scenarios unless they are formally issued. Repair Approval Forms might be used for specific agreements on repairs but do not encompass the broader regulatory and procedural requirements outlined in Technical Directives.
