Which type of data can be used without further approval for an appliance major repair?

The manufacturer's manual serves as the correct response because it contains specific instructions, guidelines, and data directly from the manufacturer regarding the maintenance, repair, and component specifications for the appliance in question. This information is essential for ensuring that repairs are performed according to the latest industry standards and manufacturer recommendations, which are crucial for maintaining safety and airworthiness.

When it comes to major repairs, the manufacturer's manual provides the foundational data that technicians need to execute the repair without requiring additional modifications or approvals. This compliance with the manufacturer's guidelines ensures that the repair aligns with safety protocols and regulatory requirements.

While advisory circulars may offer valuable guidance, and previously approved FAA Form 337 documents can provide examples of past repairs, neither can replace the detailed, specific information found in the manufacturer's manual for a major repair. Simplified aircraft reviews focus on more straightforward assessments and do not provide the comprehensive data available in a manufacturer's manual, making the latter the most appropriate choice for use without further approval.
