 AGENCY: Federal Aviation Administration (FAA), DOT.
 ACTION: Final rule.
 SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain Airbus Helicopters Model EC155B1 helicopters. This AD was prompted by a report of difficulties when jettisoning the co-pilot door during non-scheduled maintenance. This AD requires a functional check of the pilot and co-pilot door jettisoning system and corrective actions if necessary, as specified in a European Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
 DATES: This AD is effective July 20, 2021.( print page 31610) The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of July 20, 2021.

SUPPLEMENTARY INFORMATION: Background The EASA (now European Union Aviation Safety Agency), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2015-0157, dated July 30, 2015 (EASA AD 2015-0157) (also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI), to correct an unsafe condition for Airbus Helicopters Model EC 155 B1 helicopters, all serial numbers delivered after manufacturing before June 30, 2015, and equipped with a pilot or co-pilot door jettisoning system in accordance with Airbus Helicopters Modification POST MOD 0752C05, except helicopters on which Aircraft Maintenance Manual (AMM) Task 52-11-00-712 was accomplished on both pilot and co-pilot doors since the last crew door installation. 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 Helicopters Model EC155B1 helicopters. The NPRM published in the **Federal Register** on April 22, 2021 (86 FR 21240). The NPRM was prompted by a report of difficulties when jettisoning the co-pilot door during non-scheduled maintenance. The NPRM proposed to require a functional check of the pilot and co-pilot door jettisoning system and corrective actions if necessary, as specified in an EASA AD. The FAA is issuing this AD to address jamming of the affected door jettisoning mechanism, which could reduce the ability of the flightcrew to evacuate in the event of an emergency situation. See the MCAI for additional background information. Discussion of Final Airworthiness Directive Comments The FAA gave the public the opportunity to participate in developing this final rule. 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 and the public interest require adopting this final rule as proposed, except for minor editorial changes. The FAA has determined that these minor changes: Are consistent with the intent that was proposed in the NPRM for addressing the unsafe condition; and
        Do not add any additional burden upon the public than was already proposed in the NPRM. Related Service Information Under 1 CFR Part 51 EASA AD 2015-0157 specifies procedures for doing a functional check of the pilot and co-pilot door jettisoning system and corrective actions. The corrective actions include greasing the tenons and restoring the jettison system. 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 14 helicopters of U.S. registry. The FAA estimates the following costs to comply with this AD: Estimated Costs for Required Actions
Labor cost
Parts cost
Cost per product
Cost on U.S. operators8 work-hours × $85 per hour = $680
$0
$680
$9,520
 The FAA estimates the following costs to do any necessary on-condition action that would be required based on the results of any required actions. The FAA has no way of determining the number of helicopters that might need this on-condition action: Estimated Costs of On-Condition Actions

 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.

(d) Subject Joint Aircraft System Component (JASC) Code 5210, Passenger/Crew Doors. (e) Reason This AD was prompted by a report of difficulties when jettisoning the co-pilot door during non-scheduled maintenance. The FAA is issuing this AD to address jamming of the affected door jettisoning mechanism, which could reduce the ability of the flightcrew to evacuate in the event of an emergency situation. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Requirements Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with European Aviation Safety Agency (now European Union Aviation Safety Agency) (EASA) AD 2015-0157, dated July 30, 2015 (EASA AD 2015-0157).
