Which engine issue is addressed by CA.IX.C.K1a?

• A. Engine roughness or overheating.
• B. Alternator failure.
• C. Ice buildup on wings.
• D. Propeller imbalance.

Answer: (A)

Engine abnormal operation is the focus here, specifically engine roughness or overheating. These symptoms show the engine isn’t performing normally and can quickly lead to serious damage if not managed, so pilots must recognize them and follow the non-normal procedures in the POH to protect the engine and maintain safe flight. Roughtness can indicate misfiring or ignition/fuel delivery issues, while overheating signals cooling problems or excessive thermal stress. The other options involve systems or areas outside the engine’s normal operating condition—electrical power (alternator), airframe icing on the wings, and propeller drive/imbalance—so they aren’t the engine abnormal operation addressed by this item.
