Models named: 328-100 series, 328-300 series. Read the applicability below — it usually turns on serial or part numbers too.

Model 328-100 series airplanes, as listed in Dornier Service Bulletin SB-328-24-391, dated September 11, 2001; and Model 328-300 series airplanes, as listed in Dornier Service Bulletin SB-328J-24-120, dated September 12, 2001; 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 (d) 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.

Required as indicated, unless accomplished previously. To prevent damage to the electrical wire harness, made up of wiring and a protective sleeve, which could result in electrical arcing and an increased potential for fire or explosion, accomplish the following: Inspection (a) Within 400 flight hours after the effective date of this AD, do a one-time general visual inspection to detect chafing damage to the electrical wire harness, made up of wiring and a protective sleeve, next to the fuel line at the left electric fuel pump; per Dornier Service Bulletin SB-328-24-391, dated September 11, 2001 (for Model 328-100 series airplanes); or Dornier Service Bulletin SB-328J-24-120, dated September 12, 2001 (for Model 328-300 series airplanes); as applicable. Note 2: 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.” No Chafing: Secure the Electrical Wire Harness (b) If no chafing damage to the electrical wire harness, made up of wiring and a protective sleeve, is detected during the inspection required by paragraph (a) of this AD, before further flight, secure the electrical wire harness to the fuel line using ty-rap, per Dornier Service Bulletin SB-328-24-391, dated September 11, 2001 (for Model 328-100 series airplanes); or Dornier Service Bulletin SB-328J-24-120, dated September 12, 2001 (for Model 328-300 series airplanes); as applicable. Chafing: Corrective Action(s) and Secure the Electrical Wire Harness (c) If any chafing damage to the electrical wire harness, made up of wiring and a protective sleeve, is detected during the inspection required byparagraph (a) of this AD, before further flight, do the action(s) specified in paragraphs (c)(1) and (c)(2) of this AD, as applicable, and paragraph (c)(3) of this AD, per Dornier Service Bulletin SB-328-24-391, dated September 11, 2001 (for Model 328-100 series airplanes); or Dornier Service Bulletin SB-328J-24-120, dated September 12, 2001 (for Model 328-300 series airplanes); as applicable. (1) For any damaged protective sleeve: Repair or replace the protective sleeve, per the applicable service bulletin. (2) For any damaged wiring: Replace the electrical wire harness, made up of wiring and a protective sleeve, with a new electrical wire harness, per the applicable service bulletin. (3) Secure the electrical wire harness, made up of wiring and a protective sleeve, to the fuel line using ty-rap, per the applicable service bulletin. Alternative Methods of Compliance (d) 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, Transport Airplane Directorate, FAA. 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 3: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the International Branch, ANM-116. Special Flight Permits (e) 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.
