At the O level, composite repairs are described as which of the following?

• A. General repairs
• B. Type/model/series specific repairs
• C. Cosmetic repairs
• D. Non-structural repairs

Answer: (B)

Composite repairs are defined as type/model/series specific because each aircraft model can use different laminate layups, materials, resin systems, thicknesses, and cure processes. The repair must match the exact design and manufacturing specifications for that particular type so the structural integrity, load paths, and durability are preserved. Generic or cosmetic repairs wouldn’t guarantee the right ply orientation, bonding, or curing, which are critical for load-bearing areas. Non-structural repairs would ignore the important structural requirements, which is not acceptable for composite structures. In practice, you follow the OEM repair instructions that are specific to the aircraft’s type and model to ensure a safe, effective repair.
