Complete ENGINE SHUTDOWN or FAILURE IN FLIGHT Procedure, this section.
NOTES:
1. With one thrust reverser deployed, significant airframe buffet may occur. Rudder
bias alone will not provide sufficient rudder force to overcome the yaw. The
excess rudder force may be relieved by rudder trim. Level flight can be
maintained with gear and flaps retracted, at the maximum landing weight, up to
approximately 10,000 ft.
2. If necessary for increased engine power, the main air valve on the operating
engine may be closed below 12,000 ft.
3. If an engine is shut down and the airplane is descending in icing conditions, the
operating engine main air valve should be selected to LP ON.
4. If the affected reverser restows, do not attempt an engine restart.
5. Do not pull or reset any circuit breakers associated with the Thrust Reverser
system.
