COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
 SCHEDULE OF AIRWORTHINESS DIRECTIVES

 SAAB SF340 Series Aeroplanes

 AD/SF340/66 Engine Control Quadrant - Securing
                           of Power Cam Screw

 10/98

            Applicability: SAAB Model SF340A serial numbers 004 through 159 and SAAB Model 340B aeroplanes, serial numbers 160 through 439.

            Requirement: Secure the control quadrant power cam securing screws in accordance with SAAB Service Bulletin SAAB 340-76-042 dated 28 May 1998.

            Note: LFV Airworthiness Directive 1-128 dated 29 May 1998 refers.

            Compliance: Within 1200 flight hours or six calendar months, whichever comes first, after the effective date of this Directive.

            This airworthiness directive becomes effective on 10 September 1998.

            Background: One operator has reported two instances of Power Lever (PL) binding. The cause of the binding was that the screws holding the spacer between the two PL cams in the flight idle stop unit were of an incorrect type and therefore not properly secured. The result of this situation is that the screws can back out and interfere with the PL and limit the movement to maximum 80% power or prevent PL movement in the ground power range.
