AD 2006-01-08

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 30 days after the effective date of this AD, review the airplane's maintenance records to determine if Tasks 532038-DVI-10000-1 and -2 of the BAE Systems (Operations) Limited BAe146/Avro RJ Maintenance Planning Document issued May 15, 2004, have been accomplished before the effective date of this AD. If review of the airplane's maintenance records cannot conclusively determine that Tasks 532038-DVI-10000-1 and -2 have been accomplished, do the detailed inspection specified in paragraph (g) of this AD at the applicable compliance time specified in paragraph (g)(1) or (g)(2) of this AD. If review of the airplane's maintenance records can conclusively determine that Tasks 532038-DVI-10000-1 and -2 have been accomplished, do the detailed inspection specified in paragraph (g) of this AD at the compliance time specified in paragraph (g)(3) of this AD.

At the applicable compliance time specified in paragraph (g)(1), (g)(2), or (g)(3) of this AD, do a detailed inspection of the external fuselage skin adjacent to the longeron at rib 0 from frame 29 to frame 31, in accordance with the Accomplishment Instructions of BAE Systems (Operations) Limited Inspection Service Bulletin ISB.53-177, dated June 29, 2004. If any damage is found during any inspection required by this AD, before further flight, repair in accordance with the service bulletin; except where the service bulletin specifies to repair with an approved BAE Systems (Operations) Limited repair scheme, before further flight, repair the damage according to a method approved by either the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA; or the Civil Aviation Authority (or its delegated agent).

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 mirror, magnifying lenses, etc., may be necessary. Surface cleaning and elaborate procedures may be required.”

Note 2: BAE Systems (Operations) Limited Inspection Service Bulletin ISB.53-177, dated June 29, 2004, refers to Supplemental Structural Inspection 53-20-138 of the BAE Systems (Operations) Limited BAe 146/Avro 146-RJ Maintenance Review Board Report, Revision 10, dated May 2004, as an additional source of service information for inspecting the external fuselage skin. The service bulletin also refers to the BAE Systems (Operations) Limited structural repair manual (SRM) as an additional source of service information for repairing certain damage.

Thereafter repeat the detailed inspection at intervals not to exceed 12,000 flight cycles.

(2) For airplanes on which Tasks 532038-DVI-10000-1 and -2 of the BAE Systems (Operations) Limited BAe146/Avro RJ Maintenance Planning Document issued May 15, 2004, have not been accomplished but that have accumulated more than 22,000 total flight cycles as of the effective date of this AD: Inspect before accumulating 24,000 total flight cycles or within 6 months after the effective date of this AD, whichever is first. Thereafter repeat the detailed inspection at intervals not to exceed 12,000 flight cycles.
