What is considered substantial damage?

What is considered substantial damage?

• A. Damage affecting structure or performance requiring major repair.
• B. Cosmetic damage only.
• C. Damage limited to non-structural components.
• D. Damage that does not affect flight characteristics.

Answer: (A)

Substantial damage is damage that would normally require major repair or replacement of the affected component because it affects the aircraft’s structural integrity, performance, or flight characteristics. The best choice captures the essence: damage to the structure or to how the aircraft performs that necessitates major repair. Cosmetic damage isn’t considered substantial because it doesn’t threaten airworthiness, and damage limited to non-structural components typically isn’t substantial either. Damage that doesn’t affect flight characteristics isn’t sufficient on its own to define substantial damage unless it would still require major repair to restore airworthiness, but the criterion most closely aligned with the standard threshold is damage to structure or performance requiring major repair.
