AD 2022-06-14 Requires Revising The Existing Maintenance Or Inspection Program

The FAA is superseding Airworthiness Directive (AD) 2017-12-08, which applied 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.

AD 2017-12-08 required revising the maintenance or inspection program, as applicable, to incorporate new or revised structural inspection requirements. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. The FAA is issuing this AD to address the unsafe condition on these products. This AD is effective May 19, 2022.

Supplementary Information: The Civil Aviation Authority (CAA), which is the aviation authority for the United Kingdom, has issued CAA AD G-2021-0011, dated October 8, 2021 (CAA AD G-2021-0011) (also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI), to correct an unsafe condition for all BAe 146 and AVRO 146-RJ airplanes. You may examine the MCAI in the AD docket on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA2021-1013.

The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2017-12-08, Amendment 39-18923 (82 FR 27414, June 15, 2017) (AD 2017-12-08). AD 2017-12-08 applied 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. The NPRM published in the Federal Register on November 23, 2021 (86 FR 66471). The NPRM was prompted by a determination that new or more restrictive airworthiness limitations are necessary. The NPRM proposed to require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is issuing this AD to address fatigue cracking of certain structural elements, which could adversely affect the structural integrity of the airplane. See the MCAI for additional background information.
