What action is required when damage exceeds repair limits?

When damage exceeds repair limits, replacement is the necessary action to ensure the safety and functionality of the aircraft. Repair limits are established to define the extent of damage that can be effectively repaired without compromising the structural integrity and performance of an aviation component. When damage surpasses these limits, repairing the component may not restore it to a state that meets the required safety standards.

Replacement is essential in such cases because it ensures that the component will meet performance and safety specifications. It eliminates the risk of failure that could arise from a compromised part, maintaining the overall safety of the aircraft. The other options, while they serve important purposes in certain contexts, do not address situations where the damage is too extensive for effective repair or reconditioning.
