BAE Systems (Operations) Limited Model BAe 146 Series Airplanes and Model Avro 146-RJ Series Airplanes
This AD applies to BAE Systems (Operations) Limited Model BAe 146 series airplanes and Model Avro 146-RJ series airplanes; certificated in any category; on which modification HCM01037A has been incorporated.
The FAA is adopting a new airworthiness directive (AD) for certain BAE Systems (Operations) Limited Model BAe 146 series airplanes and Model Avro 146-RJ series airplanes. This AD requires repetitive inspections to detect discrepancies of the fuselage skin and reinforcing plates along the wing to fuselage fairing access panels on the left- and right-hand sides of the airplane, and repair if necessary. This AD also provides for an optional terminating action for the repetitive inspections. This AD is prompted by a report of chafing on the wing to fuselage fairing panels. We are issuing this AD to prevent chafing of the fuselage skin and reinforcing plates, which could lead to reduced structural integrity of the airplane's 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.
The term “service bulletin,” as used in this AD, means the Accomplishment Instructions of BAE Systems (Operations) Limited Inspection Service Bulletin ISB.53-162, dated September 12, 2001.
Prior to the accumulation of 8,000 total flight cycles, or within 500 flight cycles after the effective date of this AD, whichever occurs later, do a detailed inspection to detect discrepancies (i.e., chafing outside the limits specified in the service bulletin, scoring, or cracking) of the fuselage skin and reinforcing plates along the wing to fuselage fairing access panels on the left- and right-hand sides of the airplane, in accordance with the service bulletin. Repeat the detailed inspection thereafter at intervals not to exceed 4,000 flight cycles, until the terminating action specified in paragraph (i) of this AD has been done.
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.”
If any discrepancy is found during the detailed inspection required by paragraph (g) of this AD, before further flight, repair according to a method approved by either the Manager, International Branch, ANM-116, FAA, Transport Airplane Directorate; or the Civil Aviation Authority (CAA) (or its delegated agent).
(i) Modify the fuselage skin at the wing-to-fuselage access panels, do the related repetitive investigative action, and do applicable corrective actions by accomplishing all the actions in accordance with the Accomplishment Instructions of BAE Systems (Operations) Limited Modification Service Bulletin SB.53-162-01698A, Revision 1, dated January 31, 2002. These actions terminate the repetitive inspections required by paragraph (g) of this AD. Repeat the related repetitive investigative action (which involves inspecting the protective tape and sealant for damage) thereafter at intervals not to exceed 4,000 flight cycles.
Although the service bulletin referenced in this AD specifies to submit an inspection report, 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.
