### ATA 25 Equipment & Furnishings – Flight Compartment Door Locking Device – Replacement

Manufacturer(s): Dornier Luftfahr t GmbH; Fairchild-Dornier Gm bH; 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 t he cockpit door locking device Part Number (P/N) 001A252A3914012 had fall en off the RH cockpit wall, blocking the RH power/condition lever pulley/cabl e 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, coul d cause interference with the engineand/or flight control cables, possibly resulting in reduced control of the aeroplane.
To address that uns afe 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 hol der 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 Consequently, this AD retains the requirements of AD 2009-0082, which is superseded, and requires the replacement of the current P/N 001A252A3914012 with new designed P/N 001A252A3914016 cockpit door locking device, or the removal of the cockpitEASA AD No.: 2010-0169
