4176 Federal Register / Vol. 89, No. 15 / Tuesday, January 23, 2024 / Rules and Regulations 49 15 U.S.C. 1681c(a)(1). 50 In the original FCRA, ‘‘[r]ecords of arrest, indictment, or conviction of crime’’ were reportable for seven years, starting at the ‘‘date of disposition, release, or parole.’’ 15 U.S.C. 1681c(a)(5) (1996). The 1998 amendment to the FCRA deleted this paragraph. Consumer Reporting Employment Clarification Act, Public Law 105–347, sec. 5(2), 112 Stat. 3211. The amendment moved ‘‘records of arrest’’ to pre-existing paragraph (a)(2), which now requires the reporting of ‘‘[c]ivil suits, civil judgment, and records of arrest’’ to end seven years after ‘‘date of entry,’’ 15 U.S.C. 1681c(a)(2). See Public Law 105–347, sec. 5(1), 112 Stat. 3211. (Information of this type can be reported ‘‘until the governing statute of limitations has expired,’’ if that period is longer. 15 U.S.C. 1681c(a)(2).) The 1998 amendment also removed criminal convictions altogether from the restriction on reporting obsolete information. Id., sec. 5(3), codified at 15 U.S.C. 1681c(a)(5) (prohibiting reporting, past seven years, of ‘‘any other adverse item of information, other than records of convictions of crimes’’). 51 Moran , 943 F.3d at 1185. 52 15 U.S.C. 1681s. 53 15 U.S.C. 1681o (emphasis added). 54 15 U.S.C. 1681n (emphasis added); Safeco Ins. Co. of Am. v. Burr, 551 U.S. 47, 57–58 (2007) (construing meaning of ‘‘willful’’). 55 Safeco Ins., 551 U.S. at 70; Fuges v. Sw. Fin. Servs., Ltd., 707 F.3d 241, 253 (3d Cir. 2012). 56 Public Law 111–203, 124 Stat. 1376 (2010). 57 12 U.S.C. 5512(b)(1). 58 44 U.S.C. 3501–3521. 59 5 U.S.C. 801 et seq. bankruptcy cases, the reporting period ends 10 years ‘‘from the date of entry of the order for relief or the date of adjudication.’’ 49 Unlike these provisions, section 605(a)(5) contains no indication that Congress intended to tie the end of the reporting period to something other than the occurrence of the adverse item. The pre-1998 version of section 605(a) explicitly made ‘‘disposition’’ of a ‘‘record[ ] . . . of indictment’’ the trigger for the seven- year reporting period; however, a 1998 amendment deleted that provision. 50 This amendment ‘‘significantly altered [the] statute,’’ indicating clearly that the end of the reporting period under section 605(a)(5) depends on the date of the adverse item itself—not on the date of disposition. 51 In addition to provisions authorizing Federal and State enforcement, 52 the FCRA contains two provisions relating to civil liability to consumers for noncompliance. Section 617 provides that ‘‘any person who is negligent in failing to comply with any requirement imposed under this title with respect to any consumer is liable to that consumer in an amount equal to’’ the consumer’s actual damages, and costs and reasonable attorney’s fees. 53 Section 616 provides that ‘‘any person who willfully fails to comply with any requirement imposed under this title with respect to any consumer is liable to that consumer in an amount equal to’’ actual or statutory damages of up to $1,000 per violation, such punitive damages as the court allows, and costs and reasonable attorney’s fees. 54 A violation is willful when it is inconsistent with ‘‘authoritative guidance’’ from a relevant agency. 55 As with any guidance issued by the CFPB on the FCRA, or predecessor agencies that were responsible for administering the FCRA prior to the CFPB’s creation, consumer reporting agencies risk liability under section 616 if they violate the FCRA in a manner described in this advisory opinion, regardless of whether the consumer reporting agencies were previously liable for willful violations prior to its issuance. II. Regulatory Matters This advisory opinion is an interpretive rule issued under the Bureau’s authority to interpret the FCRA, including under section 1022(b)(1) of the Consumer Financial Protection Act of 2010, 56 which authorizes guidance as may be necessary or appropriate to enable the Bureau to administer and carry out the purposes and objectives of Federal consumer financial laws. 57 The Bureau has determined that this advisory opinion does not impose any new or revise any existing recordkeeping, reporting, or disclosure requirements on covered entities or members of the public that would be collections of information requiring approval by the Office of Management and Budget under the Paperwork Reduction Act. 58 Pursuant to the Congressional Review Act, 59 the Bureau will submit a report containing this interpretive rule and other required information to the United States Senate, the United States House of Representatives, and the Comptroller General of the United States prior to the rule’s published effective date. The Office of Information and Regulatory Affairs has designated this interpretive rule as not a ‘‘major rule’’ as defined by 5 U.S.C. 804(2).

FOR FURTHER INFORMATION CONTACT : Vladimir Ulyanov, Aviation Safety Engineer, FAA, 1600 Stewart Avenue, Suite 410, Westbury, NY 11590; phone: 206–231–3229; email: Vladimir.Ulyanov@faa.gov. SUPPLEMENTARY INFORMATION : Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Airbus SAS Model A330–200, A330–200 Freighter, A330– 300, A330–800, and A330–900 series airplanes. The NPRM published in the Federal Register on July 20, 2023 (88 FR 46699). The NPRM was prompted by AD 2023–0052, dated March 14, 2023, issued by EASA, which is the Technical Agent for the Member States of the European Union (EASA AD 2023–0052) (also referred to as the MCAI). The MCAI states that a determination has been made that the differential pressure test across Rib 3, part of the production ground test procedure used to confirm inner fuel tank integrity, was not properly accomplished on airplanes delivered before July 2021. In the NPRM, the FAA proposed to require a fuel tank leak test and, depending on findings, accomplishment of applicable corrective action, as specified in EASA AD 2023–0052. The FAA is issuing this AD to address lack of inner fuel tank integrity that, in the case of an uncontained engine rotor failure and subsequent fuel tank puncture, could lead to insufficient fuel available to ensure continued safe flight and landing. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2023–1498. Discussion of Final Airworthiness Directive Comments The FAA received a comment from Air Line Pilots Association, International, who supported the NPRM without change. The FAA received an additional comment from Delta Air Lines (DAL). The following presents the comment received on the NPRM and the FAA’s response. Request To Correct Service Bulletin Errors DAL requested that two discrepancies in the service information be corrected. DAL noted that the reference to ‘‘R(L) INNER TK’’ should be changed to ‘‘L(R) INNER TK,’’ and there is a discrepancy in the range of possible capacitance values for inner tank probe 6. DAL asserted that these errors make it impossible for the required actions to be accomplished. The FAA agrees. Paragraph (h)(4) has been added to this AD to change the reference to ‘‘L(R) INNER TK.’’ Paragraph (h)(5) has been added to this AD to remove the requirement to measure the capacitance values for inner tank probe 6 FIN 24QT1 (FIN 24QT2). Airbus has advised that these errors will be corrected in a future revision. Conclusion This product has been approved by the aviation authority of another country and is approved for operation in the United States. Pursuant to the FAA’s bilateral agreement with this State of Design Authority, it has notified the FAA of the unsafe condition described in the MCAI referenced above. The FAA reviewed the relevant data, considered the comments received, and determined that air safety requires adopting this AD as proposed. Accordingly, the FAA is issuing this AD to address the unsafe condition on this product. Except for minor editorial changes, and any other changes described previously, this AD is adopted as proposed in the NPRM. None of the changes will increase the economic burden on any operator. Related Service Information Under 1 CFR Part 51 EASA AD 2023–0052 specifies procedures for performing a leak test of the inner fuel tanks for discrepancies ( i.e., leaks; a leak test is failed if, during a secondary recording of capacitance values, the aft inner tank probe FIN 25QT1(FIN 25QT2) and FIN 123QT1(FIN 123QT2) values reduce by 2pF when compared with those in the initial recording) and, depending on findings, accomplishing applicable corrective action. Corrective actions include performing the applicable fault isolation and rectification. Airbus Service Bulletin A330–28– 3141, dated December 16, 2022, specifies serial numbers of affected airplanes. This material 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 128 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: E STIMATED C OSTS FOR R EQUIRED A CTIONS Labor cost Parts cost Cost per product Cost on U.S. operators 4 work-hours × $85 per hour = $340 .............................................................................................. $0 $340 $43,520 The FAA has received no definitive data on which to base the cost estimates for the on-condition actions specified in this AD. 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.

ACTION : Final rule. SUMMARY : The FAA is adopting a new airworthiness directive (AD) for all Bombardier, Inc., Model BD–100–1A10 airplanes. This AD was prompted by reports from the supplier that some overheat detection sensing elements of the bleed air leak detection system were manufactured with insufficient salt fill, which can result in an inability to detect hot bleed air leaks. This AD requires revising the existing airplane flight manual (AFM) to include procedures to prevent takeoff with an active bleed air leak annunciated while on the ground. This AD also requires testing the overheat detection sensing elements, marking each serviceable sensing element with a witness mark, and replacing each nonserviceable part with a serviceable part. This AD also prohibits the installation of affected parts. The FAA is issuing this AD to address the unsafe condition on these products. DATES : This AD is effective February 27, 2024. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of February 27, 2024.

SUPPLEMENTARY INFORMATION : Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Bombardier, Inc., Model BD–100–1A10 airplanes. The NPRM published in the Federal Register on September 29, 2023 (88 FR 67118). The NPRM was prompted by AD CF–2023– 09, dated February 14, 2023, issued by Transport Canada, which is the aviation authority for Canada (referred to after this as the MCAI). The MCAI states that Bombardier received reports from the supplier of the overheat detection sensing elements of a manufacturing quality escape. Some of the sensing elements of the bleed air leak detection system were manufactured with insufficient salt fill. This condition can result in an inability to detect hot bleed air leaks, which can cause damage to surrounding structures and systems and prevent continued safe flight and landing. In the NPRM, the FAA proposed to require revising the existing AFM to include procedures to prevent takeoff with an active bleed air leak annunciated while on the ground. The FAA also proposed to require testing the overheat detection sensing elements, marking each serviceable sensing element with a witness mark, and replacing each nonserviceable part with a serviceable part. The FAA also proposed to prohibit the installation of affected parts. The FAA is issuing this AD to address the unsafe condition on these products. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2023–1890. Discussion of Final Airworthiness Directive Comments The FAA received a comment from an anonymous commenter who has experience troubleshooting and maintaining environmental control systems (bleed air). No changes to the AD were requested. The commenter stated revising the AFM procedures will prevent costly maintenance and implementing extra safety features will also be cost effective and favor pilot safety. The FAA infers that the commenter supports the AD. Conclusion This product has been approved by the aviation authority of another country and is approved for operation in the United States. Pursuant to the FAA’s bilateral agreement with this State of Design Authority, it has notified the FAA of the unsafe condition described in the MCAI referenced above. The FAA reviewed the relevant data and determined that air safety requires adopting this AD as proposed. Accordingly, the FAA is issuing this AD to address the unsafe condition on this product. 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. Related Service Information Under 1 CFR Part 51 The FAA reviewed Liebherr Service Bulletin CFD–F1958–26–01, dated May 6, 2022, which specifies part numbers for affected sensing elements.
