Aileron and Elevator Control Gimbal Joint 4/2004

Applicability: All Model TB9 and TB10 aircraft, without MOD 10-0209-27 or Service Bulletin No.

BS 10-140 incorporated.

Requirement: Inspect the aileron and elevator control gimbal joints in accordance with Socata Service Bulletin TB No. 10-130 Revision 2, dated January 2004.

Note: DGAC AD F-2003-368 R2 refers.

Compliance: 1. Within 300 flight hours or 12 months, whichever occurs first; following delivery of the aircraft or replacement of an aileron or elevator gimbal joint;

or

Within 50 flight hours after 27 November 2003, whichever occurs later.

2. Repeat thereafter at intervals not to exceed 110 flight hours or 14 months, whichever occurs first.

The compliance times remain unchanged by this issue. This Amendment becomes effective on 15 April 2004.

Background: Failure of an aileron control gimbal joint shear pin could result in disconnection of the joint and consequent loss of control. This Directive requires inspection of the shear and joint pins for security and the application of paint witness marks to the pins.

Amendment 1 extended the inspection to the elevator control gimbal joints and changed compliance times.

Amendment 2 is issued in response to a revision of the related DGAC AD, which changes aircraft applicability to exclude aircraft that have the terminating modification for the requirements of this Directive incorporated.
