Reactivation of the Fan Cowl Hold Open Rod (HOR) Bracket/Fitting
WARNING:
BE CAREFUL WHEN YOU DO WORK ON THE ENGINE PARTS AFTER THE ENGINE SHUTDOWN. USE APPLICABLE THERMAL GLOVES. THE ENGINE PARTS CAN STAY HOT FOR ONE HOUR AFTER SHUTDOWN AND CAN BURN YOU.
WARNING:
MAKE SURE THAT YOU USE THE FAN COWL DOOR SLING TO HOLD EACH FAN COWL IN THE OPEN POSITION. IF THE SLING IS NOT USED, THE COWL WILL NOT BE HELD CORRECTLY AND CAN CLOSE QUICKLY. THIS CAN CAUSE INJURY TO PERSONS AND/OR DAMAGE TO THE COWL.
WARNING:
DO NOT EXTEND THE SLATS AND FLAPS WHEN THE THRUST REVERSER COWLS ARE DEPLOYED IN THE 45 DEG. POSITION.
WARNING:
BE CAREFUL WHEN YOU USE CONSUMABLE MATERIALS. OBEY THE MATERIAL MANUFACTURER'S INSTRUCTIONS AND YOUR LOCAL REGULATIONS.
