PREFLIGHT INSPECTION
Preight Inspection Warnings
Use of a ladder may be necessary to gain access to the wing for visual of the
stall warning heat, and pitot/static system heat.
In cold weather, it is essential to remove even the smallest accumulations
of frost, ice, snow, or slush from the wing, tail, control surfaces, propeller
blades, and the power plant air inlets. To assure complete removal of
contamination, conduct a visual and tactile inspection of all critical surfaces.
Also, ensure the control surfaces contain no internal accumulations of ice or
debris. If these requirements are not accomplished, aircraft performance will
be degraded to a point where a safe takeoff and climb may not be possible.
