AD 99-19-36 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 3042 through 3105 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 a blockage inside the de-icing tubing, which could result in a malfunction of the de-icing boot, and consequent reduced controllability of the airplane during flight in icing conditions, accomplish the following: Inspection and Corrective Action (a) Within two months after the effective date of this AD, perform a one-time detailed inspection to measure the offset of the de-icing tubing adjacent to the refueling panel on the right-hand wing in accordance with Dornier Service Bulletin SB-328-30-265, dated July 24, 1998. (1) If the de-icing tubing offset measurement conforms to the dimension shown in the service bulletin, no further action is required by this AD. (2) If the de-icing tubing does not conform to the dimension shown in the service bulletin, prior to further flight, replace it with new improved tubing in accordance with instructions provided in the service bulletin. Note 2: For the purposes of this AD, a detailed inspection is defined as: ``An intensive visual examination of a specific structural area, system, installation, or assembly to detect damage, failure, or irregularity. Available lighting is normally supplemented with a direct source of good lighting at intensity deemed appropriate by the inspector. Inspection aids such as mirror, magnifying lenses, etc. may be used. Surface cleaning and elaborate access procedures may be required.'' Alternative Methods of Compliance (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 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 (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. Incorporation by Reference (d) The actions shall be done in accordance with Dornier Service Bulletin SB-328-30-265, dated July 24, 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.
