For Requirement 1 - Before 28 December 2002.

           For Requirement 2 - Before 28 December 2002.

           For Requirement 3 - As of the effective date of this Directive.

           This Airworthiness Directive becomes effective on 28 December 2001.

           Background:  A Transport Canada investigation, of an incident involving higher than normal aileron control forces, determined that screws in the SM-300 autopilot clutch assembly had backed out sufficiently, causing the clutch to mechanically engage the autopilot servo. The screws were able to back out due to the type of screw adhesive used during manufacture of the unit.

           This Directive requires the replacement of affected servo drive units and limits their installation on aeroplanes as replacement parts.
