Discussion FAA’s Determination On March 8, 2017, we issued AD 2017–04–51, Amendment 39–18824 (82 FR 13753, March 15, 2017), for all Safran Helicopter Engines, S.A., Arriel 1A1, 1A2, 1B, 1C, 1C1, 1C2, 1D, 1D1, 1E2, 1K1, 1S, and 1S1 turboshaft engines. AD 2017–04–51 resulted from reports of fuel leaks originating from the DV on certain Arriel engines. We issued AD 2017–04–51 to prevent an engine compartment fire, in-flight shutdown, and damage to the helicopter. We are issuing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. Actions Since AD 2017–04–51 Was Issued Since we issued AD 2017–04–51, we received reports of additional fuel leaks on DVs with compliant diaphragm hole positions. Also since we issued AD 2017–04–51, the European Aviation Safety Agency (EASA) has issued AD 2017–0064R1, dated June 27, 2017, which requires initial and repetitive inspections and replacement of any DVs that do not pass inspection. Related Service Information Under 1 CFR Part 51 We reviewed Safran Helicopter Engines Alert Mandatory Service Bulletin (MSB) No. A292 73 0853, Version A, dated April 7, 2017. The Alert MSB describes procedures for inspecting, wrapping, and replacing the DV. This service information is available by the means identified in the ADDRESSES section. AD Requirements This AD requires inspecting and wrapping affected DVs and replacing those DVs found to be defective. This AD requires operators to continue to perform repetitive inspections even if the defective DV is replaced with an affected DV that is eligible for installation. FAA’s Justification and Determination of the Effective Date An unsafe condition exists that requires the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because the compliance requirements are within 10 flight hours or 7 days. Therefore, we find that notice and opportunity for prior public comment are impracticable and that good cause exists for making this amendment effective in less than 30 days. Costs of Compliance We estimate that this AD affects 200 engines installed on helicopters of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Action Labor cost Inspecting, wrapping, and replacing the DV ... 4.5 work-hours × $85 per hour = $382.50 ..... srobinson on DSKBC5CHB2PROD with RULES 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. We are 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 VerDate Sep<11>2014 16:26 Jul 21, 2017 Jkt 241001 Parts cost 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, PO 00000 Frm 00010 Fmt 4700 Sfmt 4700 $70 Cost per product $452.50 Cost on U.S. operators $90,500 (2) Is not a ‘‘significant rule’’ under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979), (3) Will not affect intrastate aviation in Alaska to the extent that it justifies making a regulatory distinction, and (4) 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.

Discussion

    On March 8, 2017, we issued AD 2017-04-51, Amendment 39-18824 (82 
FR 13753, March 15, 2017), for all Safran Helicopter Engines, S.A., 
Arriel 1A1, 1A2, 1B, 1C, 1C1, 1C2, 1D, 1D1, 1E2, 1K1, 1S, and 1S1 
turboshaft engines. AD 2017-04-51 resulted from reports of fuel leaks 
originating from the DV on certain Arriel engines. We issued AD 2017-
04-51 to prevent an engine compartment fire, in-flight shutdown, and 
damage to the helicopter.

Actions Since AD 2017-04-51 Was Issued

    Since we issued AD 2017-04-51, we received reports of additional 
fuel leaks on DVs with compliant diaphragm hole positions. Also since 
we issued AD 2017-04-51, the European Aviation Safety Agency (EASA) has 
issued AD 2017-0064R1, dated June 27, 2017, which requires initial and 
repetitive inspections and replacement of any DVs that do not pass 
inspection.

Related Service Information Under 1 CFR Part 51

    We reviewed Safran Helicopter Engines Alert Mandatory Service 
Bulletin (MSB) No. A292 73 0853, Version A, dated April 7, 2017. The 
Alert MSB describes procedures for inspecting, wrapping, and replacing 
the DV. This service information is available by the means identified 
in the ADDRESSES section.

FAA's Determination

    We are issuing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.

AD Requirements

    This AD requires inspecting and wrapping affected DVs and replacing 
those DVs found to be defective. This AD requires operators to continue 
to perform repetitive inspections even if the defective DV is replaced 
with an affected DV that is eligible for installation.

FAA's Justification and Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because the 
compliance requirements are within 10 flight hours or 7 days. 
Therefore, we find that notice and opportunity for prior public comment 
are impracticable and that good cause exists for making this amendment 
effective in less than 30 days.

Costs of Compliance

    We estimate that this AD affects 200 engines installed on 
helicopters of U.S. registry.
    We estimate the following costs to comply with this AD:

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.
    We are 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) Is not a ``significant rule'' under DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979),
    (3) Will not affect intrastate aviation in Alaska to the extent 
that it justifies making a regulatory distinction, and
    (4) 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.

A292 73 0853, Version A, dated April 7, 2017.
    (2) After wrapping an affected DV, as specified in paragraph 
(f)(1) of this AD, inspect the DV for fuel leakage before each first 
flight of the day. If a fuel leak is detected, replace the affected 
DV with a DV eligible for installation before the next flight.
    (3) If, during any inspection required by this AD, the wrapping 
is found defective (loose, missing, or damaged), before the next 
flight, remove the wrap and re-wrap the affected DV using the 
Accomplishment Instructions, paragraph 2.4, of Safran Helicopter 
Engines Alert MSB No. A292 73 0853, Version A, dated April 7, 2017.
    (4) If you replace the affected DV with another affected DV 
eligible for installation, you must still continue to perform the 
repetitive inspections required by paragraph (f)(2) of this AD.

(g) Installation Prohibition

    From the effective date of this AD, do not install any engine 
with an affected DV on any helicopter unless the DV has been wrapped 
and is leak-free in accordance with the instructions in paragraph 
2.4 of Safran Helicopter Engines Alert MSB No. A292 73 0853, Version 
A, dated April 7, 2017.
