No repairs shall be made to composite structures by any unit unless they meet all safety requirements listed in?

• A. AFTO-2-1-790
• B. AFTO-1-1-690
• C. TM 9-1000-1
• D. NAVAIR 00-25-101

Answer: (B)

The safety rules for repairing composite structures are established in a formal safety/publication that units must follow before any repair work. The correct source, AFTO-1-1-690, is the designated reference that outlines the required safety criteria, procedures, and approvals for performing composite repairs. It ensures personnel have the proper training, use approved repair methods, and apply appropriate safety measures and environmental controls before proceeding.

Other publications listed are not the official source for these composite repair safety requirements; they cover different topics, organizations, or aircraft systems. Therefore, they do not provide the mandated safety framework for composite repairs. Always refer to the current AFTO-1-1-690 for this purpose.
