AD 2004-06-16 Airworthiness Directives; Dornier Model 328-100 Series Airplanes
Models named: 328-100 series. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
Model 328-100 series airplanes, as listed in Dornier Service Bulletin SB-328-57-435, Revision 1, dated August 7, 2002; and Dornier Service Bulletin SB-328-57-439, Revision 1, dated March 10, 2003; certificated in any category.
Compliance
Required as indicated, unless accomplished previously. To prevent failure of the support arms of the ground spoiler assemblies due to cracking, which could result in loss of function and/or separation of the affected ground spoiler assemblies from the airplane, and consequent reduced controllability of the airplane during landing or rejected take-off operations, accomplish the following: Visual, Contour, and Clearance Inspections of Ground Spoilers, and Corrective Actions (a) Within 400 flight cycles after the effective date of this AD: Do the inspections for discrepancies of the ground spoiler assemblies and the wing flaps by doing all the actions per the Accomplishment Instructions of Dornier Service Bulletin SB-328-57-439, Revision 1, dated March 10, 2003. Any applicable corrective action must be done before further flight per the service bulletin. Note 1: For the purposes of this AD, a general visual inspection is defined as: “A visual examination of an interior or exterior area, installation, or assembly to detect obvious damage, failure, or irregularity. This level of inspection is made from within touching distance unless otherwise specified. A mirror may be necessary to enhance visual access to all exposed surfaces in the inspection area. This level of inspection is made under normally available lighting conditions such as daylight, hangar lighting, flashlight, or droplight and may require removal or opening of access panels or doors. Stands, ladders, or platforms may be required to gain proximity to the area being checked.” Inspection of Ground Spoiler Support Arms (b) Within 4 weeks after the effective date of this AD, or prior to the accumulation of 4,000 total flight cycles, whichever is later: Do an eddy current inspection for cracking in the bottom edge of the flange for ground spoiler support arms No. 3 and No. 8, left and right sides of the airplane. Do the inspection by accomplishing all of the actions per the Accomplishment Instructions of Dornier Service Bulletin SB-328-57-435, Revision 1, dated August 7, 2002. Repeat the inspection thereafter at intervals not to exceed 1,000 flight cycles. Corrective Action (c) If any cracking is found during any inspection required by paragraph (b) of this AD, before further flight, replace the affected ground spoiler assembly with a new ground spoiler assembly per the applicable section(s) of chapters 27 or 57 of the Dornier Model 328-100 Airplane Maintenance Manual. Certain Recommendations in Service Bulletins Not Required (d) Dornier Service Bulletin SB-328-57-435, Revision 1, dated August 7, 2002, states to contact Dornier if any crack is found in a support arm for a ground spoiler, and to send the affected ground spoiler to Dornier, but those actions are not required by this AD. Dornier Service Bulletin SB-328-57-439, Revision 1, dated March 10, 2003, recommends that inspection results for cracking of support arms be sent to Dornier, but that action is not required by this AD. Alternative Methods of Compliance (e) In accordance with 14 CFR 39.19, the Manager, International Branch, ANM-116, FAA, Transport Airplane Directorate, is authorized to approve alternative methods of compliance for this AD. Incorporation by Reference (f) Unless otherwise specified in this AD, the actions shall be done in accordance with Dornier Service Bulletin SB-328-57-435, Revision 1, dated August 7, 2002; and Dornier Service Bulletin SB-328-57-439, Revision 1, dated March 10, 2003; as applicable.
