SUPPLEMENTARY INFORMATION: Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2018-0284, dated December 20, 2018 (EASA AD 2018-0284), to correct an unsafe condition for Airbus Helicopters Deutschland GmbH (AHD) Model EC135 P1, EC135 P2, EC135 P2+, EC135 P3, EC135 T1, EC135 T2, EC135 T2+, EC135 T3, EC635 P2+, EC635 P3, EC635 T1, EC635 T2+, and EC635 T3 helicopters. Model EC635 P2+, EC635 P3, EC635 T1, and EC635 T3 helicopters are not certificated by the FAA and are not included on the U.S. type certificate data sheet; this AD therefore does not include those helicopters in the applicability.

The NPRM published in the Federal Register on March 30, 2021 (86 FR 16550). The NPRM was prompted by a report of increased control force in the collective axis on an AHD Model EC135 helicopter. Subsequent inspections determined that a nut on a piston of the MRA had cracked and separated from the piston rod. The NPRM proposed to require a one-time visual inspection of the MRA, as specified in an EASA AD. The FAA is issuing this AD to prevent failu…
