2009-02-09 BAE Systems (Operations) Limited (Formerly British Aerospace Regional Aircraft): Amendment 39-15799. Docket No. FAA- 2008-1141; Directorate Identifier 2008-NM-025-AD. Effective Date (a) This airworthiness directive (AD) becomes effective April 2, 2009. Affected ADs (b) None. Applicability (c) This AD applies to BAE Systems (Operations) Limited Model BAe 146-100A, -200A, and -300A series airplanes; and Model Avro 146- RJ70A, 146-RJ85A, and 146-RJ100A airplanes, certificated in any category, all models, all serial numbers. Subject (d) Air Transport Association (ATA) of America Code 53: Fuselage. Reason (e) The mandatory continuing airworthiness information (MCAI) states: During removal of forward and aft wing links, corrosion has been found on the wing links and the wing link attachment bolts in areas that are not readily accessible during the currently required Maintenance Review Board Report (MRBR) zonal inspections or Corrosion Prevention and Control Programme (CPCP) inspections. If left uncorrected, such corrosion could adversely affect the structural integrity of the wing to fuselage joint. For this reason, this Airworthiness Directive (AD) requires repetitive detailed visual inspections at the forward and aft wing links and wing link attachment bolts for signs of corrosion, replacement of corroded nuts and bolts and repair of any defects. The MRBR and CPCP will be amended to include the repeat inspections. Actions and Compliance (f) Unless already done, do the following actions: Before accumulating 48 months on the wing link since new, or within 48 months of a wing link being repaired in accordance with a BAE Systems (Operations) Limited or European Aviation Safety Agency (EASA) approved repair scheme, or within 24 months after the effective date of this AD, whichever occurs latest, and thereafter at intervals not to exceed 48 months, inspect the wing links in accordance with paragraph 2.C. of BAE Systems (Operations) Limited Inspection Service Bulletin ISB.53-203, dated May 7, 2007 ("the service bulletin''). (1) If any corrosion is found on bolts or nuts, replace the affected bolts and nuts with airworthy parts before next flight in accordance with the service bulletin. (2) If any corrosion to the wing links is found during an inspection, repair before further flight in accordance with a method approved in accordance with EASA (or its delegated agent).
