Airworthiness Directive · Amendment 39-14774 · BAE Systems (Operations) Limited Model BAe 146 Airplanes
BAE Systems (Operations) Limited Model BAe 146 Airplanes
This AD applies to BAE Systems (Operations) Limited Model BAe 146-100A, -200A, and -300A series airplanes, certificated in any category, on which Modification HCM00301A or B has been done, and on which Modification HCM01698A has not been done.
The FAA is adopting a new airworthiness directive (AD) for certain BAE Systems (Operations) Limited Model BAe 146 airplanes. This AD requires repetitive inspections to measure the depth of chafing or scoring in the skin along the full length of the wing-to-fuselage fairing from forward to aft ends at the contact between the seal and fuselage, and related investigative/corrective actions if necessary. This AD results from a report of chafing in this area. We are issuing this AD to detect and correct such chafing or scoring, which could result in reduced structural integrity of the 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.
Inspect, using a dial test indicator, to measure the depth of any chafing or scoring in the skin along the full length of the wing-to-fuselage fairing from forward to aft ends at the point of contact between the seal and fuselage on both sides of the fuselage, and do applicable related investigative/corrective actions in accordance with the Accomplishment Instructions of BAE Systems (Operations) Limited Inspection Service Bulletins ISB.53-005, Revision 2, dated February 16, 2004; and ISB.53-067, Revision 3, dated June 27, 2005; except as required by paragraph (g) of this AD. Do the inspection before the airplane accumulates 1,000 total flight cycles, or within 500 flight cycles after the effective date of this AD, whichever occurs later. Do related investigative/corrective actions and repeat the inspection to measure the chafing/scoring at the times specified in the service bulletins, as applicable, except as required in paragraph (h) of this AD.
Where BAE Systems (Operations) Limited Inspection Service Bulletins ISB.53-005, Revision 2, dated February 16, 2004; and ISB.53-067, Revision 3, dated June 27, 2005; specify to contact the manufacturer for repair instructions: Before further flight, repair using a method approved by the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA; the Civil Aviation Authority (or its delegated agent); or the EASA (or its delegated agent).
(h) This AD requires corrective actions before further flight, except where corrective actions may be deferred under specific conditions in BAE Systems (Operations) Limited Inspection Service Bulletins ISB.53-005, Revision 2, dated February 16, 2004; and ISB.53-067, Revision 3, dated June 27, 2005.
(i) Although BAE Systems (Operations) Limited Inspection Service Bulletins ISB.53-005, Revision 2, dated February 16, 2004; and ISB.53-067, Revision 3, dated June 27, 2005; specify to submit certain information to the manufacturer, this AD does not include that requirement.
Inspections and applicable investigative and corrective actions done before the effective date of this AD are acceptable for compliance with the requirements of paragraph (f) of this AD if done in accordance with one of the service bulletin versions identified in Table 1 of this AD, as applicable. The repetitive inspection may be done within 4,000 flight cycles after the most recent inspections in accordance with both BAE Systems (Operations) Limited Inspection Service Bulletins ISB.53-005 and ISB-53-067 (any revision level).
