BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ Series Airplanes
Superseded. A later AD replaced this one: AD 2011-08-11. Comply with the one in force.
This AD applies to all BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ series airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ series airplanes. This AD requires repetitive external eddy current inspections of the forward fuselage skin to detect cracking due to fatigue, and repair if necessary. This AD is prompted by evidence of cracking due to fatigue along the edges of the chemi-etched pockets in certain front fuselage canopy skin panels. We are issuing this AD to detect and correct this cracking, which could result in reduced structural integrity of the airplane fuselage.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within the applicable compliance time specified in paragraph (f)(1) or (f)(2) of this AD, perform an external eddy current inspection of the forward fuselage skin to detect cracking, in accordance with the Accomplishment Instructions of BAE Systems (Operations) Limited Modification Service Bulletin ISB.53-167, including Appendix 2, Revision 1, dated May 18, 2004.
(1) For Model BAe 146 series airplanes: Inspect before the accumulation of 16,000 total landings, or within 4,000 landings after the effective date of this AD, whichever is later.
(i) For areas where no crack is found, repeat the inspection at intervals not to exceed 8,000 landings.
(ii) For areas where any crack is found, before further flight, perform repairs in accordance with a method approved by the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA, or the Civil Aviation Authority (CAA) (or its delegated agent). No further inspection of any repaired area is required by this AD.
(2) For Model Avro 146-RJ series airplanes: Inspect before the accumulation of 10,000 total landings, or within 2,000 landings after the effective date of this AD, whichever is later.
(i) For areas where no crack is found, repeat the inspection at intervals not to exceed 4,000 landings.
(ii) For areas where any crack is found, before further flight, perform repairs in accordance with a method approved by the Manager, International Branch, ANM-116, or the CAA (or its delegated agent). No further inspection of any repaired area is required by this AD.
Inspections accomplished before the effective date of this AD in accordance with BAE Systems (Operations) Limited Inspection Service Bulletin ISB.53-167, including Appendices 2 and 3, all dated June 27, 2003, are considered acceptable for compliance with the corresponding action specified in paragraph (f) of this AD.
Although the service bulletin referenced in this AD specifies to submit Appendix 1 of the service bulletin with certain information to the manufacturer, this AD does not include that requirement.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
