Background
EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2021-0238, dated November 2, 2021 (EASA AD 2021-0238), to correct an unsafe condition for Leonardo S.p.a., formerly Finmeccanica S.p.A., AgustaWestland S.p.A., Model AW169 helicopters, serial numbers (S/N) from 69006 up to 69125 inclusive, except S/N 69040; and S/N 69130, 69132, 69133, 69134, 69136, and 69139.
[top] This proposed AD was prompted by a report of a blockage in a fuel tank vent line. The FAA is proposing this AD to detect and address the blockage, which
Related Service Information Under 1 CFR Part 51
EASA AD 2021-0238 requires a one-time inspection of the fuel tank vent lines and, depending on findings, accomplishment of applicable corrective action(s).
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 Service Information
The FAA also reviewed Leonardo Helicopters Alert Service Bulletin No. 169-205, dated September 20, 2021. This service information specifies procedures for a one-off boroscopic inspection of the right and left fuel tank vent lines.
FAA's Determination
These helicopters have been approved by EASA and are approved for operation in the United States. Pursuant to the FAA's bilateral agreement with the European Union, EASA has notified the FAA about the unsafe condition described in its AD. The FAA is proposing this AD after evaluating all known relevant information and determining that the unsafe condition described previously is likely to exist or develop on other helicopters of the same type design.
Proposed AD Requirements in This NPRM
This proposed AD would require accomplishing the actions specified in EASA AD 2021-0238, described previously, as incorporated by reference, except for any differences identified as exceptions in the regulatory text of this proposed AD and except as discussed under "Differences Between this Proposed AD and the EASA AD."
Explanation of Required Compliance Information
In the FAA's ongoing efforts to improve the efficiency of the AD process, the FAA developed a process to use some civil aviation authority (CAA) ADs as the primary source of information for compliance with requirements for corresponding FAA ADs. The FAA has been coordinating this process with manufacturers and CAAs. As a result, the FAA proposes to incorporate EASA AD 2021-0238 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2021-0238 in its entirety through that incorporation, except for any differences identified as exceptions in the regulatory text of this proposed AD. Using common terms that are the same as the heading of a particular section in EASA AD 2021-0238 does not mean that operators need comply only with that section. For example, where the AD requirement refers to "all required actions and compliance times," compliance with this AD requirement is not limited to the section titled "Required Action(s) and Compliance Time(s)" in EASA AD 2021-0238. Service information referenced in EASA AD 2021-0238 for compliance will be available at https://www.regulations.gov by searching for and locating Docket No. FAA-2022-0282 after the FAA final rule is published.
Differences Between This Proposed AD and the EASA AD
EASA AD 2021-0238 states to remove the sealant obstructions in accordance with the instructions of the service information and to contact Leonardo for approved corrective actions instructions and accomplishing those instructions within the compliance time specified therein; whereas, this proposed AD would require repair done before further flight in accordance with a method approved by the Manager, General Aviation and Rotorcraft Section, International Validation Branch, FAA; or EASA; or Leonardo S.p.a. Helicopters' EASA Design Organization Approval (DOA). If approved by the DOA, the approval must include the DOA-authorized signature.
EASA AD 2021-0238 states to inspect the fuel tank vent lines in accordance with the instructions of the service information, which specifies inspecting for evidence of a partial or total Proseal obstruction. This proposed AD would require inspecting for a partial or total Proseal obstruction.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would affect 6 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 proposed AD.
Boroscopic inspecting the fuel tank vent lines would take approximately 6 work-hours for an estimated cost of $510 per helicopter and up to $3,060 for the U.S. fleet. The FAA has no way of knowing the cost to repair a fuel tank vent line.
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 proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 this proposed regulation:
(1) Is not a "significant regulatory action" under Executive Order 12866,
(2) Would not affect intrastate aviation in Alaska, and
(3) Would not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.
