In response to a safety concern during a run-up, what did the candidate do?

• A. Checked spark plug conditions and cleaned them, then performed a run-up.
• B. Continued flight without inspection.
• C. Called maintenance and waited.
• D. Replaced the engine.

Answer: (A)

When a safety concern arises during a run-up, the priority is to verify and fix the issue on the spot before continuing. Inspecting spark plug conditions and cleaning them directly targets a common ignition-related problem that can cause misfires or uneven engine performance. Clean, properly conditioned spark plugs restore reliable ignition and, after the cleaning, performing another run-up confirms there are no abnormal indications and the engine is safe to operate. This approach demonstrates proactive troubleshooting and adherence to maintenance procedures, balancing safety with the need to proceed. In contrast, continuing without inspection risks a potential in-flight issue, waiting for maintenance could delay operations, and replacing the engine is far beyond what’s warranted for a routine run-up safety concern.
