3.10. Overspeed Governor Check. Pilots will ensure area immediately in front of and behind the aircraft is clear. (T-2) During engine run-up for the overspeed governor check, the PNF guards the brakes (i.e., ready to apply brake pressure) and is ready to assume control of the brakes/apply pressure in case of rudder pedal rod end failure. Clear outside the aircraft during this check. If the aircraft moves, reduce power, pump up the brakes, and reattempt. Power should be advanced smoothly and slowly only as high as required to verify proper function of the overspeed governor. Keep the control stick in the neutral to slightly aft position to prevent the nose gear strut from compressing during the check.
