AD 98-26-12 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, serial numbers 3005 through 3095 inclusive; certificated in any category. Note 1: This AD applies to each airplane identified in the preceding applicability provision, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. For airplanes that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (b) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.
Compliance
Required as indicated, unless accomplished previously. To prevent fatigue cracking of the fork flanges of the roll spoiler actuators due to incorrect installation of the lockplates, which could result in reduced structural integrity of the components of the roll spoiler actuators, and consequent reduced controllability of the airplane, accomplish the following: (a) Within 300 flight hours after the effective date of this AD, perform a one-time visual inspection to verify correct installation of the lockplates of the roll spoiler actuators, in accordance with Dornier Service Bulletin SB-328-27-263, dated June 29, 1998. (1) If all lockplates of the roll spoiler actuators are correctly installed, no further action is required by this AD. (2) If any lockplate of any roll spoiler actuator is installed incorrectly, prior to further flight, perform either an eddy current or dye penetrant inspection to detect cracks of the area surrounding the fork flanges of the roll spoiler actuators, in accordance with the service bulletin. (i) If no crack is detected, no further action is required by this AD. (ii) If any crack is detected, prior to further flight, replace the roll spoiler actuator with a new or serviceable roll spoiler actuator in accordance with the service bulletin. (b) An alternative method of compliance or adjustment of the compliance time that provides an acceptable level of safety may be used if approved by the Manager, International Branch, ANM-116, FAA, Transport Airplane Directorate. Operators shall submit their requests through an appropriate FAA Principal Maintenance Inspector, who may add comments and then send it to the Manager, International Branch, ANM-116. Note 2: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the International Branch, ANM-116. (c) Special flight permits may be issued in accordance with sections 21.197 and 21.199 of the Federal Aviation Regulations (14 CFR 21.197 and 21.199) to operate the airplane to a location where the requirements of this AD can be accomplished. (d) The inspection and replacement shall be done in accordance with Dornier Service Bulletin SB-328-27-263, dated June 29, 1998. This incorporation by reference was approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR part 51. Copies may be obtained from FAIRCHILD DORNIER, DORNIER Luftfahrt GmbH, P.O. Box 1103, D-82230 Wessling, Germany.

Note 3: The subject of this AD is addressed in German airworthiness directive 1998-358, dated September 10, 1998. (e) This amendment becomes effective on January 25, 1999. Issued in Renton, Washington, on December 14, 1998. Darrell M. Pederson, Acting Manager, Transport Airplane Directorate, Aircraft Certification Service.
