Airworthiness Directives; BAE Systems (Operations) Limited 
Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: 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.

DATES: This AD is effective May 19, 2022.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of May 19, 
2022.

SUPPLEMENTARY INFORMATION: 

Discussion

    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. FAA-2021-1013.
    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.

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule. The FAA has considered the comment 
received. An individual indicated their support for the NPRM.

Conclusion

    The FAA reviewed the relevant data, considered the comment 
received, and determined that air safety and the public interest 
require adopting this final rule as proposed, except for minor 
editorial changes. The FAA has determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    BAE Systems has issued Chapter 05, Time Limits/Maintenance Checks, 
of the BAe 146 Series/AVRO 146-RJ Series Aircraft Maintenance Manual, 
Revision 132, dated June 15, 2021. This service information describes 
airworthiness limitations, including life limits, maintenance tasks, 
and critical design configuration control limitations (CDCCLs).
    This service information is reasonably available because the 
interested parties have access to it through their normal course of 
business or by the means identified in the ADDRESSES section.

Costs of Compliance

    The FAA estimates that this AD affects 30 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:
    The FAA estimates the total cost per operator for the retained 
actions from AD 2017-12-08 to be $7,650 (90 work-hours x $85 per work-
hour).
    The FAA has determined that revising the maintenance or inspection 
program takes an average of 90 work-hours per operator, although the 
agency recognizes that this number may vary from operator to operator. 
Since operators incorporate maintenance or inspection program changes 
for their affected fleet(s), the FAA has determined that a per-operator 
estimate is more accurate than a per-airplane estimate. Therefore, the 
agency estimates the average total cost per operator to be $7,650 (90 
work-hours x $85 per work-hour).
    The FAA estimates the total cost per operator for the new actions 
to be $7,650 (90 work-hours x $85 per work-hour).

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. Subtitle VII: Aviation Programs, 
describes in more detail the scope of the Agency's authority.
    The FAA is issuing this rulemaking under the authority described in 
Subtitle VII, Part A, Subpart III, Section 44701: General requirements. 
Under that section, Congress charges the FAA with promoting safe flight 
of civil aircraft in air commerce by prescribing regulations for 
practices, methods, and procedures the Administrator finds necessary 
for safety in air commerce. This regulation is within the scope of that 
authority because it addresses an unsafe condition that is likely to 
exist or develop on products identified in this rulemaking action.

Regulatory Findings

    The FAA determined that this AD will not have federalism 
implications under Executive Order 13132. This AD will not have a 
substantial direct effect on the States, on the relationship between 
the national government and the States, or on the distribution of power 
and responsibilities among the various levels of government.
    For the reasons discussed above, I certify that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Will not affect intrastate aviation in Alaska, and
    (3) Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.

this AD: After accomplishing the revision required by paragraph (g) 
of this AD, no alternative actions (e.g., inspections), intervals, 
and/or CDCCLs may be used, unless the actions, intervals, and/or 
CDCCLs are approved as an alternative method of compliance (AMOC) in
