Preflight Inspection
Aircraft Surface . . . . . . . . . . . . . . . CHECK FREE OF SNOW,
ICE AND FROST
Failure to remove snow, ice, or frost accumulation on the
aircraft prior to flight may result in serious aerodynamic dis-
turbances and unbalanced flight loads that may cause struc-
tural damage in flight. Takeoff distance and climb
performance also can be adversely affected to a hazardous
level.
Q
Ice may be removed by spraying with suitable deice fluid
such as isopropyl alcohol. Do not spray deicing fluid in
areas where spray or fluid may enter the engine air inlets.
Deicing fluid may be used to clean these areas providing
it is thoroughly wiped clean before starting.
Q
Remove ice, snow, and dirt from landing gear shock
struts and wheel wells. Check gear doors, position
switches, squat switches, wheels, and tires.
Q
Carefully inspect the engine inlet, outlet, and fan for ice
buildup from freezing precipitation. Look closely at the
fan; ice can form on the back of the blades, causing an
imbalance if it is not removed.
Control Surfaces . . . . . . . . . . . . . . CHECK FREE OF SNOW,
ICE AND FROST
Snow removal from the control surfaces must be complete
to ensure proper travel. Special attention must be given to
control the refreezing of water resulting from deicing with
heated air.
Pitot/Static Ports . . . . . . . . . . . . . . . . . . . . . . CLEAR OF ICE
Ice formations in the proximity of the static ports or on the
pitot tube can cause erroneous instrument indications.
