Discussion EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD No. 2016– 0216, dated October 28, 2016, to correct an unsafe condition for Leonardo Helicopters (previously Finmeccanica S.p.A., previously AgustaWestland) Model AW189 helicopters, serial numbers 49007 through 49021, 49023, 49029, 49033, 49035, 89001, 89003, 89004, 92001, 92003, and 92005. The EASA AD does not apply to windows that have been reinstalled at least once since helicopter delivery and windows that are part of bubble window kit part number (P/N) 8G5620F00111. EASA advises that during a scheduled replacement of emergency exit window seals on helicopters in service, an excessively high level of pushing force was required to jettison some of the windows. According to EASA, further investigation determined the windows were installed with glue applied in locations that were not in accordance with the approved design. This condition, if not corrected, could prevent the jettisoning of helicopter emergency exit windows, possibly affecting the evacuation of crew and passengers during an emergency situation, EASA advises. EASA consequently requires replacement of the seal and the filler wedges of the E:\FR\FM\02NOP1.SGM 02NOP1 50848 Federal Register / Vol. 82, No. 211 / Thursday, November 2, 2017 / Proposed Rules emergency exit windows installed in the cockpit doors and cabin. The FAA is in the process of updating AgustaWestland’s name change to Leonardo Helicopters on its type certificate. Because this name change is not yet effective, this proposed AD specifies AgustaWestland. 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 its AD. We are proposing this AD because we evaluated all known relevant information and determined that an unsafe condition is likely to exist or develop on other products of the same type design. Related Service Information We reviewed Leonardo Helicopters Bollettino Tecnico No. 189–118, dated October 20, 2016. This service information specifies replacing the seal and filler wedges on all cockpit door and cabin emergency exit windows of Model AW189 helicopters, except on those windows that have been replaced or that are part of bubble window kit P/N 8G5620F00111. Proposed AD Requirements This proposed AD would require within 75 hours time-in-service, replacing the seal and filler wedges on all emergency exit windows installed in the cockpit doors and cabin. Costs of Compliance We estimate that this proposed AD would affect 2 helicopters of U.S. Registry and that labor costs average $85 per work-hour. Based on these estimates, we expect that removing and replacing the window seals and fillers would require 40 work-hours and parts would cost about $834, for a total cost of $4,234 per helicopter and $8,468 for the U.S. fleet. nlaroche on DSK9F9SC42PROD with PROPOSALS 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 VerDate Sep<11>2014 14:57 Nov 01, 2017 Jkt 244001 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 We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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, I certify this proposed regulation: 1. Is not a ‘‘significant regulatory action’’ under Executive Order 12866; 2. Is not a ‘‘significant rule’’ under the 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 proposed AD and placed it in the AD docket.

Discussion EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD No. 2016– PO 00000 Frm 00006 Fmt 4702 Sfmt 4702 50849 0263–E, dated December 24, 2016 (AD 2016–0263–E), 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. According to EASA, an investigation revealed the damage was caused by 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 proposed AD specifies Agusta. FAA’s Determination These helicopters have been approved by the aviation authority of Italy and are approved for operation in the United States.

Discussion

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD No. 2016-0216, dated October 28, 
2016, to correct an unsafe condition for Leonardo Helicopters 
(previously Finmeccanica S.p.A., previously AgustaWestland) Model AW189 
helicopters, serial numbers 49007 through 49021, 49023, 49029, 49033, 
49035, 89001, 89003, 89004, 92001, 92003, and 92005. The EASA AD does 
not apply to windows that have been reinstalled at least once since 
helicopter delivery and windows that are part of bubble window kit part 
number (P/N) 8G5620F00111.
    EASA advises that during a scheduled replacement of emergency exit 
window seals on helicopters in service, an excessively high level of 
pushing force was required to jettison some of the windows. According 
to EASA, further investigation determined the windows were installed 
with glue applied in locations that were not in accordance with the 
approved design.
    This condition, if not corrected, could prevent the jettisoning of 
helicopter emergency exit windows, possibly affecting the evacuation of 
crew and passengers during an emergency situation, EASA advises. EASA 
consequently requires replacement of the seal and the filler wedges of 
the

[[Page 50848]]

emergency exit windows installed in the cockpit doors and cabin.
    The FAA is in the process of updating AgustaWestland's name change 
to Leonardo Helicopters on its type certificate. Because this name 
change is not yet effective, this proposed AD specifies AgustaWestland.

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 its AD. We are 
proposing this AD because we evaluated all known relevant information 
and determined that an unsafe condition is likely to exist or develop 
on other products of the same type design.

Related Service Information

    We reviewed Leonardo Helicopters Bollettino Tecnico No. 189-118, 
dated October 20, 2016. This service information specifies replacing 
the seal and filler wedges on all cockpit door and cabin emergency exit 
windows of Model AW189 helicopters, except on those windows that have 
been replaced or that are part of bubble window kit P/N 8G5620F00111.

Proposed AD Requirements

    This proposed AD would require within 75 hours time-in-service, 
replacing the seal and filler wedges on all emergency exit windows 
installed in the cockpit doors and cabin.

Costs of Compliance

    We estimate that this proposed AD would affect 2 helicopters of 
U.S. Registry and that labor costs average $85 per work-hour. Based on 
these estimates, we expect that removing and replacing the window seals 
and fillers would require 40 work-hours and parts would cost about 
$834, for a total cost of $4,234 per helicopter and $8,468 for the U.S. 
fleet.

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

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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, I certify this proposed regulation:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Is not a ``significant rule'' under the 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
