2005-15-11: Fatigue damage in the fuselage

2005-15-11 BAE Systems (Operations) Limited (Formerly British Aerospace Regional Aircraft): Amendment 39-14200. Docket No. FAA- 2005-21137; Directorate Identifier 2002-NM-86-AD. Effective Date (a) This AD becomes effective August 30, 2005. Affected ADs (b) None. Applicability: (c) This AD applies to all BAE Systems (Operations) Limited Model Jetstream 4101 airplanes, certificated in any category. Unsafe Condition (d) This AD was prompted by a review of primary airframe fatigue test results and a Maintenance Steering Group 3 (MSG-3) analysis. We are issuing this AD to detect and correct fatigue damage of the fuselage, door, engine nacelle, empennage, and wing structures, which could result in reduced structural integrity of the airplane. Compliance: (e) You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done. Service Bulletin Reference (f) The term "the service bulletin," as used in this AD, means BAE Systems (Operations) Limited Service Bulletin J41-51-001, Revision 2, dated April 30, 2003. Inspection and Corrective Actions (g) At the compliance times specified in the "Initial Compliance Time" column of Tables 1, 2, 3, 4, and 5 of this AD: Do the applicable detailed inspections and specialized inspections to detect fatigue damage, and replacement of certain bolt assemblies, and any applicable corrective actions, in accordance with the Accomplishment Instructions of the service bulletin. Do any corrective action before further flight. Repeat the inspections and replacement thereafter at intervals specified in the "Repetitive Intervals" column of Tables 1, 2, 3, 4, and 5 of this AD. Note 1: For the purposes of this AD, a detailed inspection is: "An intensive examination of a specific item, installation, or assembly to detect damage, failure, or irregularity. Available lighting is normally supplemented with a direct source of good lighting at an intensity deemed appropriate. Inspection aids such as mirrors, magnifying lenses, etc. may be necessary. Surface cleaning and elaborate procedures may be required."
