Federal Register / Vol. 86, No. 39 / Tuesday, March 2, 2021 / Rules and Regulations resulting in injury to the seat occupants during an accident. See the MCAI for additional background information.
The European Union Aviation Safety Agency EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD
20190088R1, dated November 8, 2019
EASA AD 20190088R1 also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI, to correct an unsafe condition for certain Airbus Helicopters Model AS332C, AS332C1, AS332L, AS332L1, AS332L2, EC225LP, AS365N2, AS 365
N3, EC 155B and EC155B1 helicopters with an energy-absorbing seat. EASA
advised that during certification of an energy-absorbing seat with a new part number, the labels placards that require keeping the space under the seat free of any object were not systematically installed. EASA stated that this condition, if not corrected, could prompt occupants to stow objects under an energy-absorbing seat, which would reduce the effectiveness of the seat and the occupants chance of surviving an accident. EASA
consequently issued AD 20140204, dated September 11, 2014; corrected September 12, 2014 which corresponds to FAA AD 20152601 to require a one-time inspection for the presence of labels placards and, if they were missing or unreadable, making and installing labels placards prohibiting the placing of an object under an energy absorbing seat. EASA later advised, in EASA AD 20170226, dated November 17, 2017 EASA AD 20170226, which superseded EASA AD 20140204, that additional new labels placards were required and that additional helicopters were affected by the unsafe condition.
In this MCAI, which supersedes EASA
AD 20170226, EASA advised that additional extended compliance times were necessary for certain helicopters.

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.
