PROCEDURES FOR EXITING
THE SEVERE ICING ~VIRONMENT:
These pu:>cedures are applicable to all flight phases from takeoff to landing. Monitor the ambient air
temperature. While severe icing may form at temperatures as cold as -18 degrees Celsius, increased
vigilance is warranted at temperatures around freezing with visible moisture present. If the visual cues
specified in the Limitations Section of the AFM for identifying severe icing conditions are observed,
accomplish the following:
• Immediately request priority handling from Air Traffic Control to facilitate a route or an altitude
change to exit the severe icing conditions in order to avoid extended exposure to flight conditions more severe
than those for which the airplane has been certificated.
• A void abrupt and excessive maneuvering that may exacerbate control difficulties.
• Do not engage the autopilot.
If the autopilot is engaged, hold the control wheel firmly and disengage the autopilot.
• If an unusual roll response or uncommanded roll control movement is observed, reduce the angle-of-
attack.
• Do not extend flaps when holding in icing conditions. Operation with flaps extended can result in a
reduced wing angle-of-attack, with the possibility of ice forming on the upper surface further
aft
on the wing
than nonnal, possibly
aft
of the protected area.
• If the flaps are extended, do not retract them until the airframe is clear of ice.
• Report these weather conditions to Air Traffic Control."
(b) Incorporating the AFM revisions, as required by this AD, may be perfonned by the owner/operator
holding at least a private pilot certificate as authorized by section 43. 7 of the Federal Aviation Regulations

this AD can be accomplished.
(d) An alternative method of compliance or adjustment of the compliance time that provides an equivalent
level of safety may be approved by the Manager, Small Airplane Directorate, FAA, 1201 Walnut, suite 900,
Kansas City, Missouri 64106. The request shall be forwarded through an appropriate FAA Maintenance Inspector,
who may add comments and then send it to the Manager, Small Airplane Directorate.
NOTE 3: Infonnation concerning the existence of approved alternative methods of compliance with this AD,
if any, may be obtained from the Small Airplane Directorate.
