Docket 96-NM-118-AD. Applicability: Model 328-100 series airplanes having serial numbers 3005 through 3019 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 otherwise 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 loosening or loss of the attachment screws, which could lead to loosening or loss of the leading edge of the wing, and consequent reduced controllability of the airplane, accomplish the following: (a) Within 6 weeks after the effective date of this AD, replace the attachment screws for leading edge 1 of the left and right wings with longer attachment screws having part number NAS7303A5, in accordance with Dornier Service Bulletin SB-328-57-058, dated November 23, 1994. (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, Standardization Branch, ANM-113, 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, Standardization Branch, ANM-113. NOTE 2: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Standardization Branch, ANM-113. (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 replacements shall be done in accordance with Dornier Service Bulletin SB-328-57-058, dated November 23, 1994.
