Airworthiness Directives; MHI RJ Aviation ULC (Type Certificate Previously Held by Bombardier, Inc.) Airplanes
AGENCY:
Federal Aviation Administration (FAA), Department of Transportation (DOT).
ACTION:
Final rule.
SUMMARY:
The FAA is adopting a new airworthiness directive (AD) for certain MHI RJ Aviation ULC Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. This AD was prompted by a determination that a certain nondestructive test (NDT) procedure associated with a certain airworthiness limitation for inspecting surface and subsurface fatigue cracks at certain fuselage stations does not address all required inspections. This AD requires using a revised NDT procedure when performing an airworthiness limitation task. This AD also prohibits the use of earlier revisions of that NDT procedure. The FAA is issuing this AD to address the unsafe condition on these products.
DATES:
This AD is effective September 27, 2022.
The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of September 27, 2022.

SUPPLEMENTARY INFORMATION:
Background
Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued TCCA AD CF-2021-47, dated December 13, 2021 (TCCA AD CF-2021-47) (also referred to as the MCAI), to correct an unsafe condition for certain MHI RJ Aviation ULC Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. You may examine the MCAI in the AD docket at www.regulations.gov by searching for and locating Docket No. FAA-2022-0590.
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain MHI RJ Aviation ULC Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. The NPRM published in the Federal Register on May 31, 2022 (87 FR 32365). The NPRM was prompted by a determination that a certain NDT procedure associated with a certain airworthiness limitation for inspecting surface and subsurface fatigue cracks at fuselage station (FS) 460 and FS513 does not address all required inspections. The NPRM proposed to require using a revised NDT procedure when performing an airworthiness limitation task. The NPRM also proposed to prohibit the use of earlier revisions of that NDT procedure. The FAA is issuing this AD to address such fatigue cracks, which could result in failure of the pressure floor skin and consequent rapid decompression of the airplane during flight. See the MCAI for additional background information.
Discussion of Final Airworthiness Directive
Comments
The FAA received no comments on the NPRM or on the determination of the cost to the public.
Conclusion
The FAA reviewed the relevant data and determined that air safety requires adopting this AD as proposed. Except for minor editorial changes, this AD is adopted as proposed in the NPRM. None of the changes will increase the economic burden on any operator. Accordingly, the FAA is issuing this AD to address the unsafe condition on these products.
Related Service Information Under 1 CFR Part 51
[top] MHI RJ Aviation ULC has issued MHI RJ CRJ200 NDTM Temporary Revision 53-109, dated March 5, 2021. This temporary revision describes an NDT procedure to do a special detailed inspection (eddy current inspection) for surface and subsurface cracks at FS460 and FS513. 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 will affect 427 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD:
| Labor cost | Parts cost | Cost per product | Cost on U.S. operators |
|---|---|---|---|
| 6 work-hours × $85 per hour = $510 | $0 | $510 | $217,770 |
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
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.
