In a scenario with multiple technicians working under approved data, what must the IA verify before sign-off?

• A. That only the final result is checked.
• B. That only the first step was performed.
• C. That each step is completed per approved data and the overall result is correct.
• D. That the data sheet was updated.

Answer: (C)

When multiple technicians are working under approved data, the IA must verify that every step called for by that data is completed and that the overall result meets the required specifications. Approved data lays out the exact procedures, tools, tolerances, and sequence to follow; skipping steps or relying only on the end result can conceal mistakes or improper installations. By confirming that each step was performed per the data and that the final configuration or function is correct, the IA ensures the work is truly compliant and airworthy. Relying solely on the final outcome or only the first step would miss potential deviations. Documentation is important, but the primary sign-off responsibility is to validate adherence to the approved data for all steps and the correctness of the final result.
