Q

Power Levers

A

Do not lift power levers in flight. Lifting the power levers in flight, or moving the power levers in flight below the flight idle position, could result in a nose-down pitch and descent rate leading to aircraft damage and injury to personnel.

(N/W/C) Engine Failure after Takeoff
• Maximum climb performance can be achieved by raising the failed engine 3 to 5° up and displacing the slip skid indicator one-half to three-quarters of a ball width toward the good engine. • If the auto feather system is being used, retarding the POWER lever below approximately 90 percent N1 before the feathering sequence is complete will deactivate the auto feather circuit and prevent automatic feathering.
