AD 98-03-12 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.

All Model 328-100 series airplanes, 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 (c) 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 delamination of the wing deicing boots and resultant inflation of the deicing boots to a distorted aerodynamic shape during flight, which could result in reduced controllability of the airplane, accomplish the following: (a) Within 120 days after the effective date of this AD, perform a one-time visual inspection of the date stamp affixed to each wing deicing boot to determine the cure date, in accordance with Dornier Service Bulletin SB-328-30-171, dated September 20, 1996, including Annexes 1 and 2 (undated). If the cure date of any deicing boot is January 31, 1994, or earlier, or if the cure date of the deicing boot cannot be determined, prior to further flight, replace the deicing boot with a new deicing boot having a cure date later than January 31, 1994, in accordance with the service bulletin. (b) As of the effective date of this AD, no person shall install on any airplane a wing deicing boot having a cure date of January 31, 1994, or earlier. (c) 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. (d) 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. (e) The actions shall be done in accordance with Dornier Service Bulletin SB-328-30-171, dated September 20, 1996, including Annexes 1 and 2 (undated). 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.
