When there is slush on the runways, examine the aircraft when it gets to the ramp. Look for slush that collected on the airplane or damage to the airplane surfaces. 1) Examine the areas that follow for ice that collected and
 damage to the skin panels (remove the ice if it is necessary): a) The leading edges b) The flaps c) The flap wells d) The vertical stabilizer e) The rudder f) The bottom and the top surface of the horizontal
 stabilizers and elevators. 2) Examine the wheel well areas for ice, slush and snow that collected. Remove the ice if it is necessary. 3) Examine the skin panels behind the wheel wells for damaged
 edges.Make sure the concentration of the deicing/anti-icing fluid is correct before you apply it to the airplane.

 WARNING: DO NOT WALK ON THE WINGS OR THE HORIZONTAL STABILIZER.
_______ ICE OR SNOW ON THESE SURFACES IS NOT SAFE. MAINTENANCE PERSONS CAN FALL WHICH MAY CAUSE PERSONAL INJURY OR AIRPLANE DAMAGE.
 (r)  Use a boomtruck, a cherry-picker or deicing/anti-icing truck to do deicing/anti-icing.
 S 663-069
 CAUTION: THE REPEATED APPLICATION OF TYPE II AND TYPE IV
_______ DEICING/ANTI-ICING FLUIDS, WITHOUT THE SUBSEQUENT APPLICATION OF TYPE I DEICING/ANTI-ICING FLUID OR HOT WATER, MAY CAUSE A RESIDUE TO COLLECT IN AERODYNAMICALLY QUIET AREAS. THIS RESIDUE MAY REHYDRATE AND FREEZE UNDER CERTAIN TEMPERATURE, HIGH HUMIDITY AND/OR RAIN CONDITIONS. THIS RESIDUE MAY BLOCK OR IMPEDE CRITICAL FLIGHT CONTROL SYSTEMS. THIS RESIDUE MAY REQUIRE REMOVAL.
 (2)  Specific Requirements
 (a)  Control Surfaces
 1)  Retract the wing flaps, slats, and spoilers during icing conditions or when the snow falls. If it is necessary to operate these controls, make sure they are not blocked by ice or snow before you retract them.
 NOTE: If an airplane comes to the gate with the flaps not
____ fully retracted during icing conditions or when the snow falls, examine those flaps that are not fully retracted. Look for ice or snow that has collected before they are retracted.
 2)  All of the control surfaces must have no ice, snow, or frost on them. After you remove the ice, make sure there no moisture collected in the hinges, guide tracks and actuators for the flight controls. This moisture culd subsequently freeze. Apply deicing/anti-icing fluid for protection.
 WARNING: TO AVOID PERSONAL INJURY, ENSURE THAT THE STABILIZER
_______ TRIM WHEEL HANDLE IS STOWED PRIOR TO USING ELECTRIC TRIM.
 3) Stabilizer trim - Full Airplane Nose Down (Fig. 304)
 a)  Set stabilizer to the APL NOSE DOWN limit to prevent deicing fluid and slush run-off from entering the stabilizer balance panel cavity.
 b)  Trim the airplane to the electrical APL NOSE DOWN limit. Then continue trimming manually to the manual APL NOSE DOWN limit.

 4) Open the leading edge devices and look for ice or snow.Wing and Horizontal Tail Surfaces
 CAUTION:_______ BE CAREFUL WHEN YOU REMOVE THE ICE AND SNOW FROM THE
 WING AND TAIL SURFACES NEAR THE VORTEX GENERATORS.
 IF YOU ARE NOT CAREFUL YOU CAN CAUSE DAMAGE TO THE

 VORTEX GENERATORS.
 1)  The wing and horizontal tail surfaces must have no ice, snow, and frost on them.
 NOTE: A layer of frost 1/8-inch thick or less on the lower
____ wing surfaces (in the spar area) is permitted if it is caused by very cold fuel. But, all of these areas must have no ice, snow or frost on them:
 -Leading edge devices
 -Control surfaces
 -Tab surfaces
 -The top wing surface.
 2)  The leading edge surfaces must have no ice, snow or frost on them. Examine the areas between the surfaces that move and the surfaces that do not move to make sure there is no ice.
 3)  The right and left sides of the horizontal stabilizer must get the same and full ice removal/anti-icing procedure.
