AD No.: 2010-0054 

Date: 25 March 2010 

Note: This Airworthiness Directive (AD) is issued by EASA, acting in accordance with 

Regulation (EC) No 216/2008 on behalf of the European Community, its Member States and of 

the European third countries that participate in the activities of EASA under Article 66 of that 

Regulation 

This AD is issued in accordance with EC 1702/2003, Part 21A.3B. In accordance with EC 2042/2003 Annex I, Part M.A.301, the 

continuing airworthiness of an aircraft shall be ensured by accomplishing any applicable ADs. Consequently, no person may operate an 

aircraft to which an AD applies, except in accordance with the requirements of that AD unless otherwise specified by the Agency [EC 

2042/2003 Annex I, Part M.A.303] or agreed with the Authority of the State of Registry [EC 216/2008, Article 14(4) exemption].

ATA 27 Flight Controls – Tab-to-Actuator Linkage – Reduced Inspection 

Intervals 

Manufacturer(s): Dornier Luftfahrt GmbH; Fairchild-Dornier GmbH; AvCraft Aerospace GmbH 

Applicability: Model 328-100 aeroplanes, all serial numbers 

Model 328-300 aeroplanes, all serial numbers 

Reason: 

Based on in-service experience, the System Safety Analyses for the Flight 

Controls have been reviewed and their conclusions have been accepted during 

the latest Candidate Maintenance Coordination Committee meeting. 

This review resulted in reduced inspection intervals, specifically for the flight 

controls tab-to-actuator linkage CMR** repetitive inspections, which have been 

identified as mandatory actions for continued airworthiness. 

Failure of these components or their constituent parts could lead to reduced 

control of the aeroplane. 

Consistent with the EASA policy to require compliance with any new and 

reduced airworthiness limitations by taking AD action and for the reasons 

described above, this EASA AD requires the accomplishment of the reducedinterval repetitive inspections and, depending on findings, related corrective 

action(s). In addition, this AD requires the implementation of the affected 

reduced inspection intervals and associated corrective actions into the 

operator’s approved maintenance programme.
