AGENCY: We are adopting a new airworthiness directive (AD) for certain Sikorsky Aircraft Corporation (Sikorsky) Model S–76A, S–76B, and S–76C helicopters. This AD requires inspecting the main gearbox (MGB) lower housing jet bores for leaks, paint or caulk blistering, and liner protrusion. This AD was prompted by several reports of MGB low oil pressure warnings which were determined to be the result of unsecured jet bore liners that had protruded. The actions are intended to prevent failure of the MGB from loss of oil, which could result in subsequent loss of control of the helicopter.

SUPPLEMENTARY INFORMATION: asabaliauskas on DSK5VPTVN1PROD with RULES Discussion On June 2, 2014, at 79 FR 31231, 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 Sikorsky Model S–76A, S–76B, and S– 76C helicopters with a MGB installed that has undergone certain repairs. The NPRM proposed to require, within 50 hours time-in-service (TIS), inspecting the MGB for leaks, paint or caulk blistering, and liner protrusion. If there is oil leakage or protrusion of a jet bore liner, the NPRM proposed to require replacing the MGB before further flight. The NPRM also proposed to require, within 1,500 hours TIS, replacing the MGB with an MGB that was not subject to the applicability of the NPRM unless VerDate Sep<11>2014 18:31 Jan 04, 2016 Jkt 238001 it had been repaired in accordance with a later overhaul and repair procedure. The NPRM was prompted by four reports of protruding jet bore liners on Sikorsky S–76 helicopters with a MGB, part number (P/N) 76351–09000 series, 76351–09500 series, and 76351–09600 series. During an overhaul of the MGB, the jet bore liner retaining pins were not adequately drilled into the liner, allowing the jet bore liner to move in the housing, because the overhaul and repair instruction (ORI) did not adequately describe procedures and housing wall thickness limitations for installing the retaining pins. Movement of the jet bore liner into the housing allows oil to leak between the liner and the housing, possibly resulting in loss of oil in the MGB, which could result in failure of the MGB and subsequent loss of control of the helicopter. At the time we issued the NPRM, we understood these repairs had been made in accordance with Sikorsky ORI No. 76350–065, Revisions A through E. However, the incident MGBs had only been repaired in accordance with Sikorsky ORI No. 76350–065, Revision A or earlier. Sikorsky ORI 76350–065, Revisions B through F, resolve the unsafe condition by clarifying the retaining pin installation instructions. This AD now reflects that clarification. replaced or overhauled when specified in the maintenance program. We have revised paragraph (e)(2) of this AD to require replacement of the MGB ‘‘within 3,750 hours TIS’’ instead of ‘‘within 1,500 hours TIS.’’ Sikorsky also commented that limiting acceptable repairs to those performed in accordance with Sikorksy ORI 76350–065 Revision F was unnecessary because Revision B and subsequent revisions provide installation details that are structurally equivalent to Revision F. When asked for additional information to support this comment, Sikorsky stated the changes in Revision B clarified the pin retention instructions sufficiently to resolve the oil leakage issue. Although Revision F provides for the installation of an additional pin, Sikorsky stated that this is not a significant change. Sikorsky confirmed that all reports of oil leakage involved repairs using the procedures in Revision A or earlier. We agree. We reexamined Sikorsky ORI No. 76350–065 and its revisions and found Revisions B through F structurally equivalent with only minor changes and improvements. We have changed paragraphs (a) and (e) of this AD to reference the appropriate revisions of Sikorsky ORI No. 76350– 065. Comments After our NPRM (79 FR 31231, June 2, 2014) was published, we received comments from one commenter. FAA’s Determination We have reviewed the relevant information, considered the comments received, and determined that an unsafe condition exists and is likely to exist or develop on other products of these same type designs and that air safety and the public interest require adopting the AD requirements as proposed with the changes described previously. These changes are consistent with the intent of the proposals in the NPRM (79 FR 31231, June 2, 2014), and will not increase the economic burden on any operator nor increase the scope of this AD. Request Sikorsky stated the proposed requirement to overhaul the affected MGBs within 1,500 hours TIS is overly conservative because the daily visual inspection is adequate to ensure safety until the next overhaul period. Sikorsky further commented that the 1,500 hour compliance time would be burdensome to operators and not cost effective. When asked for additional information to support this comment, Sikorsky stated that its maintenance program has a major inspection, and not a MGB overhaul, every 1,500 hours. The major inspection does not require removal of the MGB. Overhaul of the MGB for Model S76A helicopters occurs every 3,250 hours and for Model S76B/C helicopters occurs every 3,750 hours. We agree. We intended the proposed requirement to provide a terminating action that coincides with overhaul of the MGB. We incorrectly understood the 1,500-hour major inspection involved removing the MGB from the helicopter. We agree that due to the gradual loss of oil, safety is maintained with the repetitive inspections until the MGB is PO 00000 Frm 00004 Fmt 4700 Sfmt 4700 Related Service Information Under 1 CFR Part 51 Sikorsky issued Alert Service Bulletin (ASB) 76–66–50, Basic Issue, dated January 14, 2013 (ASB 76–66–50) for Model S–76A, S–76B, and S–76C helicopters with an MGB P/N 76351– 09000 series, 76351–09500 series, and 76351–09600 series, which have been repaired in accordance with ORI No. 76350–065 or ORI No. 76350–065, Revision A. ASB 76–66–50 describes procedures for inspecting each MGB lower housing jet bore for leaking oil, paint or caulk blistering, and liner protrusion. If there is any liner protrusion or leaking oil between the E:\FR\FM\05JAR1.SGM 05JAR1 Federal Register / Vol. 81, No. 2 / Tuesday, January 5, 2016 / Rules and Regulations liner and the housing, the ASB requires replacing the MGB. If there is paint or caulk blistering, the ASB requires further inspecting for leaking oil by replacing the jet bore packing, performing a ground run of the main rotor for 30 minutes, and re-inspecting the jet bore for leaking oil. This information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section. Other Related Service Information We also reviewed Sikorsky ORI No. 76350–065, Revision B, dated June 10, 2011; Revision C, dated June 27, 2011; Revision D, dated January 20, 2012; Revision E, dated January 27, 2012; and Revision F, dated May 10, 2012. This service information describes procedures for repairing the retaining ring groove areas of the MGB jet bores and installing retaining pins in the jet bore liners. Differences Between This AD and the Service Information The ASB specifies compliance by a specific calendar date, while the compliance time in this AD is in hours TIS. The ASB does not specify a terminating action for the recurring inspections of the MGB jet bores; while this AD does specify a terminating action for the recurring inspections. asabaliauskas on DSK5VPTVN1PROD with RULES Costs of Compliance We estimate that this AD affects 53 helicopters of U.S. Registry. We estimate that operators may incur the following costs in order to comply with this AD. At an average labor rate of $85 per workhour, inspecting the jet bore liners requires about 1.1 work-hours, for a cost per helicopter of $94 and a total cost to US operators of $4,982 per inspection cycle. If required, repairing a jet bore liner requires about 14 work-hours, and required parts cost $200, for a cost per helicopter of $1,390. If required, replacing the MGB requires about 134 work-hours, and required parts cost $994,000, for a cost per helicopter of $1,005,390. 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: VerDate Sep<11>2014 18:31 Jan 04, 2016 Jkt 238001 ‘‘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. We prepared an economic evaluation of the estimated costs to comply with this AD and placed it in the AD docket.

ACTION: Final rule. AGENCY: NMFS publishes regulations to implement cost recovery fee programs for the Western Alaska Community Development Quota (CDQ) Program for groundfish and halibut, and three limited access privilege programs: The American Fisheries Act (AFA), Aleutian Islands Pollock, and Amendment 80 Programs. The Magnuson-Stevens Fishery Conservation and Management Act (Magnuson-Stevens Act) authorizes and requires the collection of cost recovery fees for the CDQ Program and limited access privilege programs. Cost recovery fees recover the actual costs directly related to the management, data collection, and enforcement of the programs. The Magnuson-Stevens Act mandates that cost recovery fees not exceed 3 percent of the annual ex-vessel value of fish harvested by a program subject to a cost recovery fee. This action is intended to promote the goals and objectives of the Magnuson-Stevens Act, the Fishery Management Plan for Groundfish of the Bering Sea and Aleutian Islands Management Area (FMP), and other applicable laws.

Airworthiness Directives; Sikorsky Aircraft Corporation 
Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Sikorsky Aircraft Corporation (Sikorsky) Model S-76A, S-76B, and S-76C 
helicopters. This AD requires inspecting the main gearbox (MGB) lower 
housing jet bores for leaks, paint or caulk blistering, and liner 
protrusion. This AD was prompted by several reports of MGB low oil 
pressure warnings which were determined to be the result of unsecured 
jet bore liners that had protruded. The actions are intended to prevent 
failure of the MGB from loss of oil, which could result in subsequent 
loss of control of the helicopter.

[[Page 148]]


DATES: This AD is effective February 9, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of a certain document listed in this AD as of February 9, 
2016.

SUPPLEMENTARY INFORMATION:

Discussion

    On June 2, 2014, at 79 FR 31231, 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 Sikorsky Model S-76A, S-
76B, and S-76C helicopters with a MGB installed that has undergone 
certain repairs. The NPRM proposed to require, within 50 hours time-in-
service (TIS), inspecting the MGB for leaks, paint or caulk blistering, 
and liner protrusion. If there is oil leakage or protrusion of a jet 
bore liner, the NPRM proposed to require replacing the MGB before 
further flight. The NPRM also proposed to require, within 1,500 hours 
TIS, replacing the MGB with an MGB that was not subject to the 
applicability of the NPRM unless it had been repaired in accordance 
with a later overhaul and repair procedure.
    The NPRM was prompted by four reports of protruding jet bore liners 
on Sikorsky S-76 helicopters with a MGB, part number (P/N) 76351-09000 
series, 76351-09500 series, and 76351-09600 series. During an overhaul 
of the MGB, the jet bore liner retaining pins were not adequately 
drilled into the liner, allowing the jet bore liner to move in the 
housing, because the overhaul and repair instruction (ORI) did not 
adequately describe procedures and housing wall thickness limitations 
for installing the retaining pins. Movement of the jet bore liner into 
the housing allows oil to leak between the liner and the housing, 
possibly resulting in loss of oil in the MGB, which could result in 
failure of the MGB and subsequent loss of control of the helicopter.
    At the time we issued the NPRM, we understood these repairs had 
been made in accordance with Sikorsky ORI No. 76350-065, Revisions A 
through E. However, the incident MGBs had only been repaired in 
accordance with Sikorsky ORI No. 76350-065, Revision A or earlier. 
Sikorsky ORI 76350-065, Revisions B through F, resolve the unsafe 
condition by clarifying the retaining pin installation instructions. 
This AD now reflects that clarification.

Comments

    After our NPRM (79 FR 31231, June 2, 2014) was published, we 
received comments from one commenter.

Request

    Sikorsky stated the proposed requirement to overhaul the affected 
MGBs within 1,500 hours TIS is overly conservative because the daily 
visual inspection is adequate to ensure safety until the next overhaul 
period. Sikorsky further commented that the 1,500 hour compliance time 
would be burdensome to operators and not cost effective. When asked for 
additional information to support this comment, Sikorsky stated that 
its maintenance program has a major inspection, and not a MGB overhaul, 
every 1,500 hours. The major inspection does not require removal of the 
MGB. Overhaul of the MGB for Model S76A helicopters occurs every 3,250 
hours and for Model S76B/C helicopters occurs every 3,750 hours.
    We agree. We intended the proposed requirement to provide a 
terminating action that coincides with overhaul of the MGB. We 
incorrectly understood the 1,500-hour major inspection involved 
removing the MGB from the helicopter. We agree that due to the gradual 
loss of oil, safety is maintained with the repetitive inspections until 
the MGB is replaced or overhauled when specified in the maintenance 
program. We have revised paragraph (e)(2) of this AD to require 
replacement of the MGB ``within 3,750 hours TIS'' instead of ``within 
1,500 hours TIS.''
    Sikorsky also commented that limiting acceptable repairs to those 
performed in accordance with Sikorksy ORI 76350-065 Revision F was 
unnecessary because Revision B and subsequent revisions provide 
installation details that are structurally equivalent to Revision F. 
When asked for additional information to support this comment, Sikorsky 
stated the changes in Revision B clarified the pin retention 
instructions sufficiently to resolve the oil leakage issue. Although 
Revision F provides for the installation of an additional pin, Sikorsky 
stated that this is not a significant change. Sikorsky confirmed that 
all reports of oil leakage involved repairs using the procedures in 
Revision A or earlier.
    We agree. We reexamined Sikorsky ORI No. 76350-065 and its 
revisions and found Revisions B through F structurally equivalent with 
only minor changes and improvements. We have changed paragraphs (a) and 
(e) of this AD to reference the appropriate revisions of Sikorsky ORI 
No. 76350-065.

FAA's Determination

    We have reviewed the relevant information, considered the comments 
received, and determined that an unsafe condition exists and is likely 
to exist or develop on other products of these same type designs and 
that air safety and the public interest require adopting the AD 
requirements as proposed with the changes described previously. These 
changes are consistent with the intent of the proposals in the NPRM (79 
FR 31231, June 2, 2014), and will not increase the economic burden on 
any operator nor increase the scope of this AD.

Related Service Information Under 1 CFR Part 51

    Sikorsky issued Alert Service Bulletin (ASB) 76-66-50, Basic Issue, 
dated January 14, 2013 (ASB 76-66-50) for Model S-76A, S-76B, and S-76C 
helicopters with an MGB P/N 76351-09000 series, 76351-09500 series, and 
76351-09600 series, which have been repaired in accordance with ORI No. 
76350-065 or ORI No. 76350-065, Revision A. ASB 76-66-50 describes 
procedures for inspecting each MGB lower housing jet bore for leaking 
oil, paint or caulk blistering, and liner protrusion. If there is any 
liner protrusion or leaking oil between the

[[Page 149]]

liner and the housing, the ASB requires replacing the MGB. If there is 
paint or caulk blistering, the ASB requires further inspecting for 
leaking oil by replacing the jet bore packing, performing a ground run 
of the main rotor for 30 minutes, and re-inspecting the jet bore for 
leaking oil.
    This information is reasonably available because the interested 
parties have access to it through their normal course of business or by 
the means identified in the ADDRESSES section.

Other Related Service Information

    We also reviewed Sikorsky ORI No. 76350-065, Revision B, dated June 
10, 2011; Revision C, dated June 27, 2011; Revision D, dated January 
20, 2012; Revision E, dated January 27, 2012; and Revision F, dated May 
10, 2012. This service information describes procedures for repairing 
the retaining ring groove areas of the MGB jet bores and installing 
retaining pins in the jet bore liners.

Differences Between This AD and the Service Information

    The ASB specifies compliance by a specific calendar date, while the 
compliance time in this AD is in hours TIS. The ASB does not specify a 
terminating action for the recurring inspections of the MGB jet bores; 
while this AD does specify a terminating action for the recurring 
inspections.

Costs of Compliance

    We estimate that this AD affects 53 helicopters of U.S. Registry. 
We estimate that operators may incur the following costs in order to 
comply with this AD. At an average labor rate of $85 per work-hour, 
inspecting the jet bore liners requires about 1.1 work-hours, for a 
cost per helicopter of $94 and a total cost to US operators of $4,982 
per inspection cycle. If required, repairing a jet bore liner requires 
about 14 work-hours, and required parts cost $200, for a cost per 
helicopter of $1,390. If required, replacing the MGB requires about 134 
work-hours, and required parts cost $994,000, for a cost per helicopter 
of $1,005,390.

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