"THE FOLLOWING WEATHER CONDITIONS
MAY BE CONDUCIVE TO SEVERE
IN-FLIGHT ICING:
• Visible rain at temperatures below 0 degrees Celsius ambient air temperature.
• Droplets that splash or splatter on impact at temperatures below 0 degrees Celsius ambient air temperature.
PROCEDURES FOR EXITING
THE SEVERE ICING ENVIRONMENT:
These procedures 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.
• Avoid 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 normal,
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 performed by the owner/operator holding at
least a private pilot certificate as authorized by section 43.7 of the Federal Aviation Regulations (14 CFR 43.7), and
must be entered into the aircraft records showing compliance with this AD in accordance with section 43.9 of the
Federal Aviation Regulations (14 CFR 43.9).
(c) Special flight permits may be issued in accordance with sections 21.197 and 21.199 of the Federal Aviation
Regulations (14 CFR 21.197 and 21.199) to operate the airplane to a location where the requirements of 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: Information concerning the existence of approved alternative methods of compliance with this AD, if any,
may be obtained from the Small Airplane Directorate.
(e) All persons affected by this directive may examine information related to this AD at the FAA, Central Region,
Office of the Regional Counsel, Room 1558, 601 E. 12th Street, Kansas City, Missouri 64106
(f) This amendment (39-10336) becomes effective on March 13, 1998.
FOR FURTHER INFORMATION CONTACT: Mr John P. Dow, Sr., Aerospace Engineer, Small Airplane Directorate,
Aircraft Certification Service, 1201 Walnut, suite 900, Kansas City, Missouri 64106, telephone (816) 426-6932 facsimile
