Applicability: Model 328-100 series airplanes having serial numbers 3005 through 3024 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 abnormal functions of the bus power control units and the generator control units, which could result in electrical short circuits in the electrical power distribution systems and a subsequent fire, accomplish the following:

(a) Within 3 months after the effective date of this AD, perform the requirements of paragraph (a)(l) and (a)(2) of this AD, in accordance with Dornier Service Bulletin SB-328-24-061, Revision 1, dated November 3, 1994.

(1) Remove the generator control units 2PC and 12PC and replace them with new improved units having part number 118-000-1. And,

(2) Remove bus power control unit 20PC and replace it with a new improved unit having part number 106-000-3.

(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 removals and replacements shall be done in accordance with Dornier Service Bulletin SB-328-24-061, Revision 1, dated November 3, 1994, which contains the following effective pages:
