Federal Register / Vol. 86, No. 129 / Friday, July 9, 2021 / Rules and Regulations The Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows:
PART 39AIRWORTHINESS
DIRECTIVES
1. The authority citation for part 39
continues to read as follows:

Authority: 49 U.S.C. 106g, 40113, 44701.
39.13

Amended
2. The FAA amends 39.13 by adding the following new airworthiness directive:

20211303 Safran Helicopter Engines, S.A. Type Certificate previously held by Turbomeca, S.A.: Amendment 39
21608; Docket No. FAA20201180;
Project Identifier MCAI202000517E.
a Effective Date This airworthiness directive AD is effective August 13, 2021.
b Affected ADs None.
c Applicability This AD applies to Safran Helicopter Engines, S.A. Type Certificate previously held by Turbomeca, S.A. Arriel 2B, 2B1, 2C, 2C1, 2C2, 2S1 and 2S2 model turboshaft engines with a fuel filter pre-blockage pressure switch, part number 9 550 17 200
0, and serial number S/N 00001 to 12753, inclusive, and S/N A0001 to A0247, inclusive, installed.
d Subject Joint Aircraft System Component JASC
Code 7321, Fuel Control/Turbine Engines.
e Unsafe Condition This AD was prompted by reports from the manufacturer of non-conforming fuel filter pre-blockage pressure switches manufactured before December 2016. The FAA is issuing this AD to prevent the non-conformity of the fuel filter pre-blockage pressure switch, which can cause its non-activation in case of fuel system contamination, with consequent opening of the by-pass without indication in the cockpit. The unsafe condition, if not addressed, could result in uncommanded inflight shut-down of the engine, an emergency autorotation landing on a single engine helicopter, or an uncommanded in-flight shut-down of both engines on a twin engine helicopter.

filter by-pass indicator pop-up has been activated.
2 Within the next 300 hydro-mechanical metering unit HMU operating hours or 180
days after the effective date of this AD, whichever occurs first, perform an operational test of the fuel filter pre-blockage pressure switch in accordance with Task 73
2301750801A01Pre-Blockage Pressure Switch of the Fuel Filter Tests Electrical, dated November 30, 2012, the Task from the Turbomeca Arriel 2 S1 Maintenance Manual.
3 During any visual inspection required by paragraph g1 of this AD, if the fuel filter by-pass indicator pop-up has been activated or, during the operational test required by paragraph g2 of this AD, any discrepancy is detected as described by the Task, before next flight, replace the fuel filter pre-blockage pressure switch with a part eligible for installation.
4 The actions required by paragraph g1
of this AD may be performed by the owner/
operator pilot holding at least a private pilot certificate, and must be entered into the aircraft records showing compliance with this AD, in accordance with 14 CFR 43.9
a1 through 4 and 14 CFR 91.417a2v.
The records must be maintained as required by 14 CFR 91.417, 121.380, or 135.439.
h Terminating Action Passing the operational test no failure detected of the fuel filter pre-blockage pressure switch, as required by paragraph g2 of this AD, or replacement of the fuel filter pre-blockage pressure switch with a part eligible for installation, constitutes a terminating action for the repetitive visual inspections required by paragraph g1 of this AD for that engine.
i Definition A part eligible for installation is a fuel filter pre-blockage pressure switch that is not listed in the Applicability, paragraph c, of this AD, or a fuel filter pre-blockage pressure switch that has passed the operational test no discrepancies detected required by paragraph g2 of this AD.
