EASA AIRWORTHINESS DIRECTIVE 

AD No.: 2010-0169 

Date: 13 August 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]. 

Type Approval Holder’s Name : 

328 Support Services GmbH 

Type/Model designation(s) : 

328 aeroplanes 

TCDS Number : EASA.A.096 

Foreign AD: Not applicable 

Supersedure: This AD supersedes EASA AD 2009-0082 dated 07 April 2009. 

ATA 25 Equipment & Furnishings – Flight Compartment Door Locking 

Device – Replacement 

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

Applicability: Model 328-100 aeroplanes, all serial numbers, and 

Model 328-300 aeroplanes, all serial numbers. 

Reason: An incident has been reported with a Dornier 328-100 aeroplane, where the 

right-hand (RH) power lever jammed in flight-idle position during the landing 

roll-out. The aeroplane was stopped by excessive braking. 

The reason for the jamming was that the cockpit door locking device Part 

Number (P/N) 001A252A3914012 had fallen off the RH cockpit wall, blocking 

the RH power/condition lever pulley/cable cluster below the door. Although the 

affected aeroplane had been modified, the technical investigation showed that 

a loose Cockpit Door Locking device could also occur on 328-100 and 328-300 

aeroplanes with a standard installation. 

This condition, if not corrected, could cause interference with the engineand/or flight control cables, possibly resulting in reduced control of the 

aeroplane. 

To address that unsafe condition, EASA issued AD 2009-0082 as an interim 

solution, to require a one-time inspection of the cockpit door locking device and 

the surrounding area and the reporting of all findings to the TC holder. 

Since that AD was issued, the TC holder has developed an improved cockpit 

door locking device, P/N 001A252A3914016. Consequently, this AD retains the 

requirements of AD 2009-0082, which is superseded, and requires the 

replacement of the current P/N 001A252A3914012 with new designed P/N 

001A252A3914016 cockpit door locking device, or the removal of the cockpit
