What is the first step if experiencing uncommanded power changes or loss of power?

• A. PCL - MID RANGE
• B. PCL - OFF
• C. PMU SWITCH - OFF
• D. Execute PEL

Answer: (A)

The first step when experiencing uncommanded power changes or a loss of power is to adjust the Power Control Lever (PCL) to the mid-range position. This action helps stabilize engine performance and regain control over the power output. By setting the PCL to mid-range, the pilot can reduce the chance of the engine entering an undesirable operating condition, which might occur if the power level is too high or too low.

This step is crucial because it allows for a more manageable and controlled response to the situation, providing time to assess and execute further procedures safely. Other options may involve more drastic measures or later steps in the checklist but beginning with adjusting the PCL helps maintain operational control.
