(a) Effective Date This airworthiness directive (AD) is effective May 22, 2024. (b) Affected ADs This AD replaces AD 2022-25-18, Amendment 39-22274 (87 FR 75915, December 12, 2022; corrected December 27, 2022 (87 FR 79236)). (c) Applicability This AD applies to all BAE Systems (Operations) Limited Model BAe 146-100A, -200A, and -300A airplanes and Model Avro 146-RJ70A, 146-RJ85A, and 146-RJ100A airplanes, certificated in any category. (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 MLG side stay outer link and MLG collapse, which could result in a runway departure and 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) Requirements Except as specified in paragraphs (h) and (i) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, United Kingdom (U.K.) Civil Aviation Authority (CAA) (U.K. CAA) AD G-2023-0004R1, dated November 16, 2023 (U.K. CAA AD G-2023-0004R1).
