 Department of Transportation Federal Aviation Administration 14 CFR Part 39
[Docket No. FAA-2021-0826; Project Identifier MCAI-2021-00300-R]
RIN 2120-AA64
 AGENCY: Federal Aviation Administration (FAA), DOT.
 ACTION: Notice of proposed rulemaking (NPRM).
 SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Helicopters Deutschland GmbH Model EC135P2+, EC135P3, EC135T2+, and EC135T3 helicopters. This proposed AD was prompted by reports that certain aft and forward fitting assemblies, which are not approved for installation on certain helicopters, were installed on those helicopters as part of the outboard load system. Operators of those helicopters might not be aware of the applicable overhaul or life limits for those fitting assemblies. This proposed AD would require inspecting the aft and forward fitting assemblies of the outboard load system to determine the part number, re-identifying the part if necessary, inspecting each affected part for damage (which may be indicated by signs of corrosion, mechanical damage, loose rivets, or cracks) and, depending on the findings, corrective actions, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.
 DATES: The FAA must receive comments on this proposed AD by November 8, 2021.
 ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods: *Federal eRulemaking Portal:*

Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2021-0066, dated March 8, 2021 (EASA AD 2021-0066), to correct an unsafe condition for Airbus Helicopters Deutschland GmbH (formerly Eurocopter Deutschland GmbH and Eurocopter España S.A.) Model EC135 P2+, EC135 P3, EC135 T2+, EC135 T3, EC635 P2+, EC635 P3, EC635 T1, EC635 T2+, and EC635 T3 helicopters, serial numbers (S/Ns) 0866 to 1166 inclusive, except S/Ns 1007, 1102, and 1145, and except helicopters on which Airbus Helicopters Service 
                    ( print page 52852)
                    Bulletin EC135-85-063 has been embodied in service. Model EC635 P2+, EC635 P3, EC635 T1, EC635 T2+, and EC635 T3 helicopters are not certificated by the FAA and are not included on the U.S. type certificate data sheet, except where the U.S. type certificate data sheet explains that the Model EC635T2+ helicopter having serial number 0858 was converted from Model EC635T2+ to Model EC135T2+. This proposed AD, therefore, does not include Model EC635 P2+, EC635 P3, EC635 T1, EC635 T2+, and EC635 T3 helicopters in the applicability. This proposed AD was prompted by reports that aft and forward fitting assemblies, having part number L851M2810103, were installed as part of the outboard load system on helicopters having S/Ns 0886 and up. The affected fitting assemblies are not approved for installation on helicopters having those serial numbers. Operators of those helicopters might not be aware of the applicable overhaul or life limits for those fitting assemblies. The FAA is proposing this AD to address failure of affected aft and forward fitting assemblies and consequent loss of external cargo, resulting in personal injury or injury to persons on the ground. See EASA AD 2021-0066 for additional background information. Related Service Information Under 1 CFR Part 51 EASA AD 2021-0066 requires a one-time inspection of each aft and forward fitting assembly of the outboard load system to identify the part number, re-identifying the part number if necessary, a one-time inspection of an affected fitting assembly for damage, and corrective action. The corrective action includes replacing any damaged fitting. 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. 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 2021-0066, described previously, as incorporated by reference, except for any differences identified as exceptions in the regulatory text of this proposed 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 2021-0066 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2021-0066 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 2021-0066 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 2021-0066. Service information required by EASA AD 2021-0066 for compliance will be available at 
                    *https://www.regulations.gov*
                     by searching for and locating Docket No. FAA-2021-0826 after the FAA final rule is published. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 69 helicopters of U.S. Registry. The FAA estimates the following costs to comply with this proposed 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 
                    ( print page 52853)
                    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.
