1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. 2. The FAA amends § 39.13 by: a. Removing Airworthiness Directive (AD) 2005-06-14, Amendment 39-14024 (70 FR 15574, March 28, 2005; corrected April 14, 2005 (70 FR 19681)); and b. Adding the following new AD: 2022-25-18 BAE Systems (Operations) Limited: Amendment 39-22274; Docket No. FAA-2022-1574; Project Identifier MCAI-2022-01362-T. (a) Effective Date This airworthiness directive (AD) is effective December 27, 2022. (b) Affected ADs This AD replaces AD 2005-06-14, Amendment 39-14024 (70 FR 15574, March 28, 2005; corrected April 14, 2005 (70 FR 19681)) (AD 2005-06-14). (c) Applicability This AD applies to BAE Systems (Operations) Limited Model BAe 146-100A, -200A, and -300A airplanes and Model Avro 146-RJ-RJ70A, 146-RJ85A, and 146-RJ100A airplanes, certificated in any category, with main landing gear (MLG) side stay outer links having Safran Landing Systems part number 200884304, 200884305, 200884346, 200884347, 201105300, 201105301, 201105308, 201105309, 201299300, 201299301, 201299305, or 201299306. (d) Subject Air Transport Association (ATA) of America Code 32, Landing gear. (e) Unsafe Condition This AD was prompted by reports of cracking on the shoulders of a main landing gear (MLG) side stay outer link. The FAA is issuing this AD to address cracking of the MLG side stay outer link. The unsafe condition, if not addressed, could lead to failure of the side stay outer link and MLG collapse, which could result in a runway departure, and could result in the engine or wing contacting the ground. The engine or wing contacting the ground could result in damage to the airplane, an increased risk of fire, the airplane flipping, and injury to occupants. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Retained Inspections, With New Terminating Action This paragraph restates the requirements of paragraph (f) of AD 2005-06-14, with new terminating action. For airplanes having any side stay identified in Messier-Dowty Service Bulletin 146-32-147, dated May 29, 2001: At the applicable time specified in paragraph (g)(1) or (2) of this AD, perform a detailed inspection for cracks of the outer links on the MLG side stays, in accordance with the Accomplishment Instructions of BAE Systems (Operations) Limited Inspection Service Bulletin ISB.32-156, Revision 1, dated July 3, 2001. Repair cracks before further flight in accordance with the Accomplishment Instructions of BAE Systems (Operations) Limited Inspection Service Bulletin ISB.32-156, Revision 1, dated July 3, 2001. Thereafter, repeat the inspection at intervals not to exceed 2,000 flight cycles, until the actions specified in paragraph (h) of this AD have been done or the initial inspection required by paragraph (i) of this AD has been done. Although BAE Systems (Operations) Limited Inspection Service Bulletin ISB.32-156, Revision 1, dated July 3, 2001, specifies to report certain information to the manufacturer, this AD does not require a report. (1) If the number of flight cycles accumulated on the side stay can be positively determined: Inspect before the accumulation of 2,000 total flight cycles on the side stay, or within 500 flight cycles after May 2, 2005 (the effective date of AD 2005-06-14), whichever occurs later. (2) If the number of flight cycles accumulated on the side stay cannot be positively determined: Inspect within 500 flight cycles after May 2, 2005 (the effective date of AD 2005-06-14). (h) Retained Optional Terminating Action for Paragraph (g) of This AD, With No Changes This paragraph restates the optional terminating action of paragraph (g) of AD 2005-06-14, with no changes. Relocation of each affected grease nipple to the upper surface of the outer link of the MLG side stays terminates the repetitive inspections required by paragraph (g) of this AD, if the relocation action is done in accordance with paragraph 2.C. of the Accomplishment Instructions of BAE Systems (Operations) Limited Inspection Service Bulletin ISB.32-156, Revision 1, dated July 3, 2001. (i) New Requirements Except as specified in paragraph (j) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, United Kingdom Civil Aviation Authority AD G-2022-0018, dated October 18, 2022 (U.K. CAA AD G-2022-0018). (j) Exceptions to U.K. CAA AD G-2022-0018 (1) Where U.K. CAA AD G-2022-0018 refers to its effective date, this AD requires using the effective date of this AD. (2) The "Remarks" section of U.K. CAA AD G-2022-0018 does not apply to this AD. (3) Where paragraph (2) of U.K. CAA AD G-2022-0018 refers to "discrepancies ( i.e. cracks or other adverse findings)," replace the text "discrepancies ( i.e. cracks or other adverse findings)," with "any cracking." (4) Where U.K. CAA AD G-2022-0018 refers to ASB.32-A189, this AD requires using BAE Systems (Operations) Limited Alert Service Bulletin ASB.32-A189, dated September 16, 2022. (k) No Reporting Requirement Although BAE Systems (Operations) Limited Alert Service Bulletin ASB.32-A189, dated September 16, 2022, specifies to submit certain information to the manufacturer, this AD does not include that requirement.
