AD 98-07-12 Airworthiness Directives; Dornier Model 328-100 Series Airplanes
Models named: 328-100. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
All Model 328-100 airplanes having serial number 3005 through 3047 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 (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.
Compliance
Required as indicated, unless accomplished previously. To prevent structural damage to the horizontal or vertical stabilizer, and potential injury to persons on the ground due to loosened wing/body fairing panels that may separate from the airplane, accomplish the following: Restatement of the Requirements of AD 94-21-02 (a) Within 25 hours time-in-service after October 26, 1994 (the effective date of AD 94-21-02, amendment 39-9043), tighten the screws and quick-release fasteners on the wing/body fairing panels, in accordance with Dornier Alert Service Bulletin ASB-328-53-004, dated August 2, 1994. Repeat these procedures thereafter at intervals not to exceed 100 hours time-in-service. Note 2: The proper torque values are specified in the alert service bulletin. New Requirements of this AD (b) Within 24 months after the effective date of this AD, modify the left and right top fairing attachments by installing new fastener systems and increasing the torque values applied to these fasteners, in accordance with Dornier Service Bulletin SB-328-53- 144, Revision 2, dated September 18, 1996. Accomplishment of this modification constitutes terminating action for the repetitive tightening actions required by paragraph (a) of this AD. Note 3: Installation of the new fastener systems and the application of new torque values accomplished prior to the effective date of this AD in accordance with Dornier Service Bulletin SB-328- 53-144, dated December 14, 1995, or Revision 1, dated January 18, 1996, is considered acceptable for compliance with the requirements of paragraph (b) of this AD. [[Page 16096]] (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.
