AD 2009-21-06

(a) This airworthiness directive (AD) becomes effective November 20, 2009.

(b) None.

(c) This AD applies to all 328 Support Services GmbH Dornier Model 328-100 and -300 airplanes, certificated in any category.

(d) Air Transport Association (ATA) of America Code 25: Equipment/furnishings.

(e) The mandatory continuing airworthiness information (MCAI) states:

A recent 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 investigation by the operator revealed that the cockpit door locking device Part Number 001A252A3914012 had fallen off the RH cockpit wall and blocked 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 engine- and/or flight control cables, possibly resulting in reduced control of the aeroplane.

For the reasons described above, this AD requires a one-time inspection of the cockpit door locking device and the surrounding area [for proper installation] and the reporting of all findings to the TC [type certificate] holder. This AD is considered to be an interim action and the retrofit of a new design may be implemented later.

The corrective action is re-torquing the attachment screws.

(f) Unless already done, do the following actions.

(1) Within 3 months after the effective date of this AD, do a detailed visual inspection of the cockpit door locking device and the surrounding area for proper installation, in accordance with the Accomplishment Instructions of 328 Support Services Service Bulletin SB-328-25-485 or SB-328J-25-235, both dated January 28, 2009, as applicable.

(2) If any discrepancy is found during the inspection specified in paragraph (f)(1) of this AD, before further flight, do the corrective action in accordance with the Accomplishment Instructions of 328 Support Services Service Bulletin SB-328-25-485 or SB-328J-25-235, both dated January 28, 2009, as applicable.

(3) Submit a report of the findings (both positive and negative) of the inspection required by paragraph (f)(1) of this AD to the Manager, Attention Dept P1, 328 Support Services GmbH, Customer Services, P.O.B. 1252, D-82231 Wessling, Fed. Rep. of Germany; Fax +49 (0) 8153 88111-6565, at the applicable time specified in paragraph (f)(3)(i) or (f)(3)(ii) of this AD. The report must include the inspection results, a description of any discrepancies found, the airplane serial number, and the number of landings and flight hours on the airplane.

(i) If the inspection was done on or after the effective date of this AD: Submit the report within 30 days after the inspection.

(ii) If the inspection was accomplished prior to the effective date of this AD: Submit the report within 30 days after the effective date of this AD.
