In what situation would a splice repair be commonly employed?

A splice repair is commonly employed to connect two structural parts together, particularly when restoring the integrity of an aircraft's structure after damage. This type of repair involves overlapping two sections of material and securing them, effectively filling in gaps or weaknesses that may have developed.

When structural components have been compromised, such as through wear or impact, a splice is a practical solution to ensure the load is properly distributed across the adjoining sections. This method maintains the strength and structural integrity required for safe flight operations.

While other options may suggest legitimate repair situations, they do not specifically relate to the primary function of a splice repair, which is to create a strong connection between parts. For instance, addressing metal fatigue might involve different repair techniques focused on reinforcing or replacing the exhausted material. Surface scratches are usually treated with sanding or coating, rather than splicing. Reinforcing existing structures could involve various methods, but splicing specifically addresses the need to connect and restore the continuity of structural elements.
