The FAA is adopting a new airworthiness directive AD for certain Safran Helicopter Engines, S.A. Safran Helicopter Engines Arriel 2B, 2B1, 2C, 2C1, 2C2, 2S1 and 2S2 model turboshaft engines. This AD was prompted by reports of non-conforming fuel filter pre-blockage pressure switches. This AD
requires repetitive visual inspections of the fuel filter by-pass indicator pop-up, a one-time operational test of the fuel filter pre-blockage pressure switch and, depending on the findings, replacement of the fuel filter pre-blockage pressure switch with a part eligible for installation. The FAA is issuing this AD
to address the unsafe condition on these products.
DATES: This AD is effective August 13, 2021.
The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD

SUPPLEMENTARY INFORMATION:
Background The FAA issued a notice of proposed rulemaking NPRM to amend 14 CFR
part 39 by adding an AD that would apply to certain Safran Helicopter Engines Arriel 2B, 2B1, 2C, 2C1, 2C2, 2S1 and 2S2 model turboshaft engines.
The NPRM published in the Federal Register on February 22, 2021 86 FR
10501. The NPRM was prompted by reports of non-conforming fuel filter pre-blockage pressure switches. In the NPRM, the FAA proposed to require repetitive visual inspections of the fuel filter by-pass indicator pop-up, a onetime operational test of the fuel filter pre-blockage pressure switch and, depending on the findings, replacement of the fuel filter pre-blockage pressure switch with a part eligible for installation. The FAA is issuing this AD
to address the unsafe condition on these products.
The European Union Aviation Safety Agency EASA, which is the Technical Agent for the Member States of the European Community, has issued EASA
AD 20190180, dated July 25, 2019
referred to after this as the MCAI, to address the unsafe condition on these products. The MCAI states:
Occurrences have been reported of nonconforming fuel filter pre-blockage pressure switches, manufactured before December 2016. The non-conformity of the fuel filter pre-blockage pressure switch can cause its non-activation in case of fuel system contamination, with consequent opening of the by-pass without indication in the cockpit.
This condition, if not detected and corrected, and in case of fuel contamination, could lead to an uncommanded in-flight shut-down, possibly resulting in an emergency autorotation landing on a single engine helicopter, or to a double uncommanded in-flight shut-down on a twin engine helicopter.
To address this potential unsafe condition, SAFRAN issued the MSB, providing inspection instructions.
For the reasons described above, this EASA AD requires repetitive daily visual checks of the fuel filter by-pass indicator pop-up. This EASA AD also requires a one-
