Airworthiness Directive · Amendment 39-17009 · Equipment/furnishings
328 Support Services GmbH Airplanes
This AD applies to 328 Support Services GmbH (Type Certificate previously held by AvCraft Aerospace GmbH; Fairchild Dornier GmbH; Dornier Luftfahrt GmbH) Model 328-100 and -300 airplanes, certificated in any category, all serial numbers.
We are superseding an existing airworthiness directive (AD) for all 328 Support Services GmbH (Type Certificate previously held by AvCraft Aerospace GmbH; Fairchild Dornier GmbH; Dornier Luftfahrt GmbH) Model 328-100 and -300 airplanes. That AD currently requires performing a detailed visual inspection of the cockpit door locking device and the surrounding area for proper installation, and corrective action if necessary. This new AD requires removing or replacing the locking device of the cockpit door; performing operational tests, and repair if necessary; and, for certain airplanes, installing gap filler parts. This AD was prompted by a report that a right-hand power lever jammed in flight-idle position during the landing roll-out, and the airplane was stopped by excessive braking. We are issuing this AD to detect and correct interference with the engine and flight control cables, which could result in reduced controllability of the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 3 months after November 20, 2009 (the effective date of AD 2009-21-06, Amendment 39-16043 (74 FR 53151, October 16, 2009)), 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.
If any discrepancy is found during the inspection specified in paragraph (g) 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.
Within 4,000 flight hours or 24 months after the effective date of this AD, whichever occurs first, do the applicable actions specified in paragraph (i)(1) or (i)(2) of this AD.
(1) For airplanes on which a door locking device with Option 521K010 is installed: Remove the locking device of the cockpit door, part number (P/N) 001A252A3914012, install the gap filler parts, and do operational tests, in accordance with the Accomplishment Instructions of 328 Support Services Service Bulletin SB-328-25-492, dated March 18, 2010 (for Model 328-100 airplanes); or 328 Support Services Service Bulletin SB-328J-25-244, dated March 18, 2010 (for Model 328-300 airplanes).
(2) For airplanes on which a door locking device with Option 521K010 is not installed: Replace the locking device of the cockpit door, P/N 001A252A3914012, with a new locking device, P/N 001A252A3914016, and do operational tests, in accordance with the Accomplishment Instructions of 328 Support Services Service Bulletin SB-328-25-491, dated March 18, 2010 (for Model 328-100 airplanes); or 328 Support Services Service Bulletin SB-328J-25-243, dated March 18, 2010 (for Model 328-300 airplanes).
If any operational test fails during the actions specified in paragraph (i)(1) or (i)(2) of this AD: Before further flight, repair in accordance with a method approved by the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA, or the European Aviation Safety Agency (or its delegated agent).
As the effective date of this AD, no person may install a locking device of the cockpit door having P/N 001A252A3914012 on any airplane.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
