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

 Embraer EMB-110 (Bandeirante) Series Aeroplanes

 AD/EMB-110/5
 Amdt 4

 Flight Control Trim System Bearings 2/92

 Applicability: All EMB-110 series.

             Requirement: 1. Disconnect and visually inspect the bearings at the following locations for jamming:

                1. At the tube terminals of the elevator, rudder and aileron trim tab control systems.

               b.                                                                             At the aileron trim tab bellcrank and actuator eyelets.

            Note 1: EMBRAER SB No 110-27-036 R2 refers.

            Note 2: Brazilian AD 82-06-01 R8 refers.

            Note 3: Compliance with AD/EMB-110/36 terminates the inspection requirement on the elevator trim rods and reverts the inspection interval to that prescribed in the Maintenance Planning Guide.

            Note 4: Modification of the aileron and rudder trim tab rod bearings in accordance with EMBRAER SB No 110-27-060 R2 terminates that inspection requirement.
 2. Action in accordance with Embraer Service Bulletin No. 110-27-060 R2. Compliance:              1. At intervals not to exceed 250 hours time in service, until compliance with
             Requirement 2.

             2. Within 1500 hours time in service or 8 months after 3 February 1992; whichever occurs first. The compliance of the previous issue of this Directive was: at intervals not exceeding 250 hours time in service after 28 February 1982 until the relevant modifications are carried out. This amendment is effective from 3 February 1992.

            Background: An inflight failure of the terminal of the control rod in an elevator trim tab has been attributed to jamming of the trim tab bearing assembly.

            Amendment 4 is issued in response to a recently issued Country of Origin Directive which requires modification action in lieu of ongoing repetitive inspections.
