icing conditions at night. This direction supersedes any relief provided  by any Minimum Equipment List.

             2.    The Normal Procedures Section of the AFM by incorporating the following:

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 A SEVERE ICING
             ENVIRONMENT: (These procedures are applicable to all flight phases from take-off 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 when visible moisture is present.

                 If the visual cues which are 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 aircraft has been certificated.

                    * Avoid abrupt and excessive manoeuvring that may exacerbate control difficulties.

                    * Do not engage the autopilot.

                    * If the autopilot had previously been engaged, hold the control wheel firmly and disengage the autopilot.

                    * If an unusual roll response or un-commanded 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.

               Note 1: Certificate of Registration holders should initiate action to ensure notification of this change is conveyed to any person who may operate their aircraft as pilot in command.

               Note 2: FAA AD99-14-01 refers.

               Certification for accomplishment of this Directive may be carried out:

                  1. after a copy of this Directive is included in the appropriate sections of the aircraft's AFM; and

                 b.    may be carried out at a minimum, by the holder of a private pilot's licence.

 Compliance: Within 30 days after the Effective date of this Amendment.

           This Amendment becomes effective 13 July 2000.

           Background:  This Directive is issued to minimise the potential hazards associated with operating the aircraft in severe icing conditions by providing more clearly defined procedures and limitations associated with such conditions.

           Amendment 1 is issued to correct a word processing error in the initial issue.
