This AD applies to all BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ airplanes, certificated in any category.
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Unless already done, do the following actions:
(1) At the applicable time specified in paragraphs (f)(1)(i) and (f)(1)(ii) of this AD, inspect for cracking, damage, and discontinuity of the airbrake upper crossbeam fastener positions and lightening holes; and replace the three rivets with Hi-lok pins; in accordance with paragraphs 2.B., 2.C., and 2.D. of the Accomplishment Instructions of BAE Systems (Operations) Limited Inspection Service Bulletin ISB.53-200, Revision 1, dated March 13, 2007. If any crack, damage, or discontinuity is found: Before further flight, repair as required by paragraph (f)(3) of this AD.

(A) Before the accumulation of 4,000 flight cycles since last inspection.
(B) Within 2,500 flight cycles (for MRBR airplanes), or within 1,000 flight cycles (for SSID airplanes) after the effective date of this AD; but not exceeding 8,000 flight cycles since the last inspection.
(C) Within 500 flight cycles after the effective date of this AD.
(2) Repeat the inspection required by paragraph (f)(1) of this AD thereafter at the applicable time specified in paragraph (f)(2)(i), (f)(2)(ii), or (f)(2)(iii) of this AD. If any crack, damage, or discontinuity is found: Before further flight, repair as required by paragraph (f)(3) of this AD.
(i) Inspect fastener positions at the rivet locations at intervals not to exceed 4,000 flight cycles.
(ii) Inspect the holes at Hi-lok pin locations at intervals not to exceed 12,000 flight cycles.
(iii) Inspect the lightening holes at intervals not to exceed 12,000 flight cycles.
(3) If any crack, damage, or discontinuity is found during any inspection required by this AD: Before further flight, do the repair in accordance with paragraph 2.E. of the Accomplishment Instructions of BAE Systems (Operations) Limited Inspection Service Bulletin ISB.53-200, Revision 1, dated March 13, 2007.
