Dornier 328 Series Aeroplanes AD/DO 328/64 Roll Spoiler Control Rod 7/2006 Applicability: Dornier 328-100 aeroplanes Serial Number 3005 through 3047 inclusive. Requirement: Unless previously accomplished, replace the roll spoiler control rod in accordance with Dornier 328 Service Bulletin No. 328-27-247 dated 19 November 1997. Note: LBA AD 1998-042 refers. Compliance: Within 30 days after the effective date of this AD. This Airworthiness Directive becomes effective on 6 July 2006. Background: Insufficient clearance between the fork end of the control rod and the bell crank could introduce a bending stress and subsequent failure of the fork end of the roll-spoiler. This can result in reduce controllability of the aeroplane. James Coyne Delegate of the Civil Aviation Safety Authority 24 May 2006
