Unsafe Condition

Fuel leakage discovered during fuel system crash impact testing activity. The fuel drain quick disconnect valve catches on the airframe cutout upon impact, resisting against the fuel bladder rotational action and causing deformation of the poppet, which leads to the valve remaining in the partially open position and subsequent fuel leakage.

FOR FURTHER INFORMATION CONTACT : Michael Hughlett, Aviation Safety Engineer, FAA, 1600 Stewart Avenue, Suite 410, Westbury, NY 11590; phone: (817) 222–5110; email: michael.Hughlett@faa.gov . SUPPLEMENTARY INFORMATION : Background Transport Canada, which is the aviation authority for Canada, has issued Transport Canada AD CF–2023– 51, dated July 11, 2023 (Transport Canada AD CF–2023–51), to correct an unsafe condition on certain serial- numbered Bell Textron Canada Limited Model 505 helicopters. The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain serial-numbered Bell Textron Canada Limited Model 505 helicopters as identified in Transport Canada AD CF–2023–51. The NPRM published in the Federal Register on May 14, 2024 (89 FR 41906). The NPRM was prompted by a fuel leakage discovered during fuel system crash impact testing activity. In a certain position, the knurls on the locking sleeve of the fuel drain quick disconnect valve contacted the airframe cutout upon impact, resisting against the fuel bladder rotational action and causing deformation of the poppet, which led to the valve remaining in the partially open position and subsequent fuel leakage. The NPRM proposed to require accomplishing the actions specified in Transport Canada AD CF–2023–51, as incorporated by reference, except for any differences identified as exceptions in the regulatory text of this AD. The FAA is issuing this AD to address the unsafe condition on these products. You may examine Transport Canada AD CF–2023–51 in the AD docket at regulations.gov under Docket No. FAA– 2024–1296. Discussion of Final Airworthiness Directive Comments The FAA received no comments on the NPRM or on the determination of the costs. Conclusion These helicopters have been approved by the aviation authority of Canada and are approved for operation in the United States. Pursuant to the FAA’s bilateral agreement with Canada, Transport Canada, has notified the FAA of the unsafe condition described in its AD. Except for minor editorial changes, this AD is adopted as proposed in the NPRM. Accordingly, the FAA is issuing this AD to address the unsafe condition on these helicopters. Material Incorporated by Reference Under 1 CFR Part 51 Transport Canada AD CF–2023–51 specifies installing a split plastic grommet around the periphery of the sump drain port fitting airframe cutout. 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. Other Related Material The FAA reviewed Bell Alert Service Bulletin 505–21–21, dated June 8, 2021. For certain serial-numbered helicopters, this material specifies procedures for installing a split plastic grommet groove around the periphery of the sump drain port fitting airframe hole cutout with the split line at the 12 o’clock position. Costs of Compliance The FAA estimates that this AD affects 145 helicopters of U.S. registry. Labor rates are estimated at $85 per work-hour. Based on these numbers, the FAA estimates the following costs to comply with this AD. Installing a grommet around the sump drain port fitting airframe hole will take approximately 1 work-hour and parts will cost a minimal amount, for an estimated cost of $85 per helicopter and $12,325 for the U.S. fleet. The FAA has included all known costs in its cost estimate. According to the manufacturer, however, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected operators. 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES ■ 1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] ■ 2. The FAA amends § 39.13 by adding the following new airworthiness directive: 2024–15–10 Bell Textron Canada Limited: Amendment 39–22802; Docket No. FAA–2024–1296; Project Identifier MCAI–2023–00844–R.
