On the effective date specified below, and for the reasons set out in the background section, the CASA delegate whose signature appears below revokes Airworthiness Directive (AD) AD/DO 228/6 and issues the following AD under subregulation 39.001(1) of CASR 1998.  The AD requires that the action set out in the requirement section (being action that the delegate considers necessary to correct the unsafe condition) be taken in relation to the aircraft or aeronautical product mentioned in the applicability section: (a) in the circumstances mentioned in the requirement section; and (b) in accordance with the instructions set out in the requirement section; and (c) at the time mentioned in the compliance section.

Dornier 228 Series Aeroplanes
AD/DO 228/6 Amdt 1  Horizontal Stabiliser Leading Edge and Ribs  2/2008

Applicability:  Model 228-100 and -101 aircraft, serial numbers 7003 through 7116, 7167, and 7168.

                Model 228-200, -201, -202, and -212 aircraft, serial numbers 8002 and subsequent.
Requirement:    In accordance with the Aircraft Maintenance Manual:

                   1. Perform a visual inspection of horizontal stabiliser leading edge skin and ribs for cracks and skin security.

                   2. Repeat the Requirement 1 inspection at the specified intervals.

                Repair/replace damaged components, if the inspection reveals damage beyond allowable limits.

                Note:  LBA AD 2001-045/2 refers.
Compliance:     As specified in the Aircraft Maintenance Manual.
                This Amendment becomes effective on 14 February 2008.
Background:     Reports were received of cracking around the riveted joints of the horizontal stabiliser skin and ribs, caused by corrosion and fatigue damage.  Undetected cracking could result in in-flight detachment of the horizontal stabiliser skin, which could lead to loss of aircraft controllability.

                Amendment 1 is issued to delete reference to Aircraft Maintenance Manual (AMM) Temporary Revisions, which have now been incorporated into the AMM.
