SUPPLEMENTARY INFORMATION: Discussion On November 2, 2017, at 82 FR 50849, the Federal Register published our notice of proposed rulemaking (NPRM), which proposed to amend 14 CFR part 39 by adding an AD that would apply to Agusta Model AW189 helicopters with certain part-numbered and serialnumbered EFS float assemblies installed. The NPRM proposed to require inspecting each float bag for punctures, replacing the pressure relief/ topping (PRT) valve O-ring part number E:\FR\FM\12MRR1.SGM 12MRR1 10566 Federal Register / Vol. 83, No. 48 / Monday, March 12, 2018 / Rules and Regulations (P/N) P–G10025 with a PRT valve gasket P/N 316683A, and replacing the inflate/ deflate protection P/N 304694A with inflate/deflate protection P/N 304694B. The NPRM also proposed to require repairing the float bag if there are any cuts, tears, punctures, or abrasion on a float bag. The proposed requirements were intended to prevent a punctured EFS float bag, which could result in loss of buoyancy of an EFS float bag while being used in an emergency water ditching and subsequent injury to helicopter occupants. The NPRM was prompted by AD No. 2016–0263–E, dated December 22, 2016 (AD 2016–0263–E), issued by EASA, which is the Technical Agent for the Member States of the European Union, to correct an unsafe condition for Leonardo S.p.A. Helicopters (previously Agusta) Model AW189 helicopters. EASA advises that during the first scheduled maintenance of an EFS kit, float bags were found punctured due to protruding parts of the pressure relief/ topping valves that were not adequately protected. EASA further states that this condition could result in a partial loss of buoyancy of the EFS float bags, possibly resulting in injury to the helicopter’s occupants in a ditching event. To prevent this unsafe condition, EASA AD 2016–0263–E requires a onetime inspection of the EFS, repair of any discrepancies found, replacing the pressure relief/topping valve O-ring with a gasket, and replacing the inflate/ deflate protection with a new design inflate/deflate protection. The FAA is in the process of updating Agusta’s name change to Leonardo Helicopters on its type certificate. Because this name change is not yet effective, this AD specifies Agusta. Comments We gave the public the opportunity to participate in developing this AD, but we did not receive any comments on the NPRM. daltland on DSKBBV9HB2PROD with RULES FAA’s Determination These helicopters have been approved by the aviation authority of Italy and are approved for operation in the United States. Pursuant to our bilateral agreement with Italy, EASA, its technical representative, has notified us of the unsafe condition described in the EASA AD. We are issuing this AD because we evaluated all information provided by EASA and determined the unsafe condition exists and is likely to exist or develop on other helicopters of the same type design and that air safety and the public interest require adopting the AD requirements as proposed. VerDate Sep<11>2014 17:01 Mar 09, 2018 Jkt 244001 Differences Between This AD and the EASA AD The EASA AD requires compliance within 15 hours time-in-service (TIS) or 10 days for helicopters flying overwater above sea state 4 or within 120 hours or 60 days for helicopters operating overwater up to sea state 4. This AD requires compliance within 120 hours TIS regardless of sea state conditions. Related Service Information We reviewed Leonardo Helicopters Bollettino Tecnico No. 189–135, dated December 20, 2016 (BT 189–135), and Aero Sekur Service Bulletin No. SB– 189–25–003, dated November 30, 2016 (SB–189–25–003), which is attached to BT 189–135 as Annex A. BT 189–135 specifies following the procedures in SB–189–25–003 to inspect and modify certain EFS kits installed on Model AW189 helicopters. Costs of Compliance We estimate that this AD affects two helicopters of U.S. Registry. We estimate that operators will incur the following costs in order to comply with this AD. Labor costs are estimated at $85 per work-hour. Inspecting each float bag, replacing the PRT valve gasket, and replacing the inflate/deflate protection require about 40 work-hours, and required parts cost about $500, for a cost per helicopter of $3,900 and a cost of $7,800 for the U.S. fleet. If required, repairing a float bag will require about 2 work-hours, and required parts cost about $90, for a cost per float bag of $260. 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 helicopters identified in this rulemaking action. PO 00000 Frm 00014 Fmt 4700 Sfmt 4700 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. We prepared an economic evaluation of the estimated costs to comply with this AD and placed it in the AD docket.

SUPPLEMENTARY INFORMATION: Background On December 13, 2016, the FAA published a final rule entitled, ‘‘Revisions to Operational Requirements for the Use of Enhanced Flight Vision Systems (EFVS) and to Pilot Compartment View Requirements for Vision Systems.’’ 1 Prior to that final rule, the operating rules for EFVS operations to 100 feet above the TDZE were contained in § 91.175(l) and (m). In the EFVS final rule, which became effective, in part, on March 13, 2017, the FAA created new 14 CFR 91.176 to contain the operating rules for EFVS operations to touchdown and rollout and for EFVS operations to 100 feet above the TDZE. As explained in the preamble to the final rule, the FAA provided an adequate transition period for operators and pilots conducting EFVS operations to 100 feet above the touchdown zone elevation.2 During this transition period, which concludes on March 13, 2018, a pilot may comply with either § 91.175(l) and (m) or § 91.176(b). Beginning on March 13, 2018, persons conducting EFVS operations to 100 feet above the TDZE must comply with § 91.176(b). Section 91.175(e)(1) included a crossreference to § 91.175(l) prior to the final rule. To accommodate the transition period, the FAA made a conforming amendment to § 91.175(e)(1), effective March 13, 2017, by adding a crossreference to § 91.176. Additionally, to conform with the conclusion of the transition period, the FAA included instructions to amend § 91.175(e)(1), effective March 13, 2018, by removing the cross-reference to § 91.175(l). Prior to the EFVS final rule, § 91.175(e)(1) allowed a pilot operating an aircraft, except a military aircraft of the United States, to immediately execute an appropriate missed approach procedure whenever operating under § 91.175(c) or (l) and the requirements of that paragraph are not met at either of the following times: (i) When the 1 81 FR 90126; corrected at 82 FR 2193, January 9, 2017; delayed at 82 FR 9677, February 8, 2017; corrected at 83 FR 1186, January 10, 2018; corrected at 83 FR 4420, January 31, 2018. 2 81 FR at 90154.

SUPPLEMENTARY INFORMATION: 

Discussion

    On November 2, 2017, at 82 FR 50849, the Federal Register published 
our notice of proposed rulemaking (NPRM), which proposed to amend 14 
CFR part 39 by adding an AD that would apply to Agusta Model AW189 
helicopters with certain part-numbered and serial-numbered EFS float 
assemblies installed. The NPRM proposed to require inspecting each 
float bag for punctures, replacing the pressure relief/topping (PRT) 
valve O-ring part number

[[Page 10566]]

(P/N) P-G10025 with a PRT valve gasket P/N 316683A, and replacing the 
inflate/deflate protection P/N 304694A with inflate/deflate protection 
P/N 304694B. The NPRM also proposed to require repairing the float bag 
if there are any cuts, tears, punctures, or abrasion on a float bag. 
The proposed requirements were intended to prevent a punctured EFS 
float bag, which could result in loss of buoyancy of an EFS float bag 
while being used in an emergency water ditching and subsequent injury 
to helicopter occupants.
    The NPRM was prompted by AD No. 2016-0263-E, dated December 22, 
2016 (AD 2016-0263-E), issued by EASA, which is the Technical Agent for 
the Member States of the European Union, to correct an unsafe condition 
for Leonardo S.p.A. Helicopters (previously Agusta) Model AW189 
helicopters. EASA advises that during the first scheduled maintenance 
of an EFS kit, float bags were found punctured due to protruding parts 
of the pressure relief/topping valves that were not adequately 
protected. EASA further states that this condition could result in a 
partial loss of buoyancy of the EFS float bags, possibly resulting in 
injury to the helicopter's occupants in a ditching event. To prevent 
this unsafe condition, EASA AD 2016-0263-E requires a one-time 
inspection of the EFS, repair of any discrepancies found, replacing the 
pressure relief/topping valve O-ring with a gasket, and replacing the 
inflate/deflate protection with a new design inflate/deflate 
protection.
    The FAA is in the process of updating Agusta's name change to 
Leonardo Helicopters on its type certificate. Because this name change 
is not yet effective, this AD specifies Agusta.

Comments

    We gave the public the opportunity to participate in developing 
this AD, but we did not receive any comments on the NPRM.

FAA's Determination

    These helicopters have been approved by the aviation authority of 
Italy and are approved for operation in the United States. Pursuant to 
our bilateral agreement with Italy, EASA, its technical representative, 
has notified us of the unsafe condition described in the EASA AD. We 
are issuing this AD because we evaluated all information provided by 
EASA and determined the unsafe condition exists and is likely to exist 
or develop on other helicopters of the same type design and that air 
safety and the public interest require adopting the AD requirements as 
proposed.

Differences Between This AD and the EASA AD

    The EASA AD requires compliance within 15 hours time-in-service 
(TIS) or 10 days for helicopters flying overwater above sea state 4 or 
within 120 hours or 60 days for helicopters operating overwater up to 
sea state 4. This AD requires compliance within 120 hours TIS 
regardless of sea state conditions.

No. SB-189-25-003, dated November 30, 2016 (SB-189-25-003), which is 
attached to BT 189-135 as Annex A. BT 189-135 specifies following the 
procedures in SB-189-25-003 to inspect and modify certain EFS kits 
installed on Model AW189 helicopters.

Costs of Compliance

    We estimate that this AD affects two helicopters of U.S. Registry. 
We estimate that operators will incur the following costs in order to 
comply with this AD. Labor costs are estimated at $85 per work-hour. 
Inspecting each float bag, replacing the PRT valve gasket, and 
replacing the inflate/deflate protection require about 40 work-hours, 
and required parts cost about $500, for a cost per helicopter of $3,900 
and a cost of $7,800 for the U.S. fleet. If required, repairing a float 
bag will require about 2 work-hours, and required parts cost about $90, 
for a cost per float bag of $260.

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 helicopters 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.
    We prepared an economic evaluation of the estimated costs to comply 
with this AD and placed it in the AD docket.
