Discussion EASA, which is the aviation authority for Germany, has issued AD No. 2016– 0142, dated July 19, 2016, to correct an unsafe condition for Airbus Helicopters Model MBB–BK 117A–1, MBB–BK 117A–3, MBB–BK 117A–4, MBB–BK 117B–1, MBB–BK 117B–2, MBB–BK 117C–1, MBB–BK 117C–2, MBB–BK 117C–2e, BO–105A, BO–105C, BO– 105D, BO105S, BO–105LS A–3 helicopters. EASA advises of several reports of a lower clamp found missing from the bellows and damaging the swashplate bearing ring before becoming detached. EASA states an investigation showed that over-torqueing can damage the clamp, which may have caused the clamp to become loose and detach. According to EASA, this condition, if not detected and corrected, could lead to loss of a swashplate clamp, resulting in loss of helicopter control. A detached clamp could damage the swashplate and pitch link or strike the tail rotor. EASA states that its AD is considered interim action and a further AD to implement a terminating action will follow. FAA’s Determination These helicopters have been approved by the aviation authority of Germany and are approved for operation in the United States. Pursuant to our bilateral agreement with Germany, 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 Under 1 CFR Part 51 We reviewed Airbus Helicopters Alert Service Bulletin (ASB) BO105–40A–107 for Model BO105 C-series, D-series and S-series helicopters; ASB BO105 LS– 40A–12 for Model BO–105LS A–3 helicopters; ASB MBB–BK117–40A–115 for Model MBB–BK 117A–1, MBB–BK 117A–3, MBB–BK 117A–4, MBB–BK 117B–1, MBB–BK 117B–2, and MBB– BK 117C–1 helicopters; and ASB MBB– BK117 C–2–62A–007 for Model MBB– BK 117C–2 and MBB–BK 117C–2e helicopters. These ASBs are all Revision 4 and all dated May 23, 2016. We also E:\FR\FM\20APP1.SGM 20APP1 Federal Register / Vol. 83, No. 77 / Friday, April 20, 2018 / Proposed Rules reviewed Airbus Helicopters ASB MBB– BK117 D–2–62A–003, Revision 2, dated May 23, 2016, for Model MBB–BK117 D–2 and MBB–BK117 D–2m helicopters. This service information specifies removing the bellows and repetitively inspecting the swashplate. This service 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. Proposed AD Requirements This proposed AD would require a one-time inspection within 50 hours time-in-service (TIS) and repetitive inspections every 100 hours TIS and every 400 hours TIS, by following the instructions in the manufacturer’s service bulletin. This proposed AD would also prohibit installing on any helicopter bellows P/N 105–10113.05, P/N 4619305044, and P/N 4638305043 and any gearbox that has these bellows installed. Differences Between This Proposed AD and the EASA AD The EASA AD requires compliance within different time intervals for some actions than what this proposed AD would require. The EASA AD allows a non-cumulative tolerance of 10 percent that may be applied to the compliance times, and this proposed AD would not. The EASA AD allows replacing the bellows clamps with cable ties before removing the bellows, and this proposed AD would not. This proposed AD would apply to Model MBB–BK 117D–2 helicopters while the EASA AD does not. The EASA AD applies to Model BO–105D helicopters, while this proposed AD would not. sradovich on DSK3GMQ082PROD with PROPOSALS Interim Action We consider this proposed AD to be an interim action. The design approval holder is currently developing a modification that will address the unsafe condition identified in this AD. Once this modification is developed, approved, and available, we might consider additional rulemaking. Costs of Compliance We estimate that this proposed AD would affect 286 helicopters of U.S. Registry and that labor costs would average $85 per work hour. Based on these estimates, we expect the following costs: • Removing and inspecting the swashplate assembly would require 3 work-hours. No parts would be needed for a cost of $255 per helicopter and $72,930 for the U.S. fleet per inspection cycle. VerDate Sep<11>2014 16:41 Apr 19, 2018 Jkt 244001 • Repairing a scratched support tube would require 3 work-hours. No parts would be needed for a cost of $255 per helicopter. • Replacing a corroded or damaged clamp would require 2 work-hours. Parts would cost $8 for a cost of $178 per helicopter. • Replacing corroded ball bearings would require 4 work-hours. Parts would cost $3,000 for a cost of $3,340 per helicopter. • Removing foreign objects from the outer deflection ring would require 2 work-hours. No parts would be needed for a cost of $170 per helicopter. 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 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. PO 00000 Frm 00011 Fmt 4702 Sfmt 4702 17511 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 aviation authority for Germany, has issued AD 
No. 2016-0142, dated July 19, 2016, to correct an unsafe condition for 
Airbus Helicopters Model MBB-BK 117A-1, MBB-BK 117A-3, MBB-BK 117A-4, 
MBB-BK 117B-1, MBB-BK 117B-2, MBB-BK 117C-1, MBB-BK 117C-2, MBB-BK 
117C-2e, BO-105A, BO-105C, BO-105D, BO105S, BO-105LS A-3 helicopters.
    EASA advises of several reports of a lower clamp found missing from 
the bellows and damaging the swashplate bearing ring before becoming 
detached. EASA states an investigation showed that over-torqueing can 
damage the clamp, which may have caused the clamp to become loose and 
detach. According to EASA, this condition, if not detected and 
corrected, could lead to loss of a swashplate clamp, resulting in loss 
of helicopter control. A detached clamp could damage the swashplate and 
pitch link or strike the tail rotor. EASA states that its AD is 
considered interim action and a further AD to implement a terminating 
action will follow.

FAA's Determination

    These helicopters have been approved by the aviation authority of 
Germany and are approved for operation in the United States. Pursuant 
to our bilateral agreement with Germany, 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.

These ASBs are all Revision 4 and all dated May 23, 2016. We also

reviewed Airbus Helicopters ASB MBB-BK117 D-2-62A-003, Revision 2, 
dated May 23, 2016, for Model MBB-BK117 D-2 and MBB-BK117 D-2m 
helicopters. This service information specifies removing the bellows 
and repetitively inspecting the swashplate.
    This service 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.

Proposed AD Requirements

    This proposed AD would require a one-time inspection within 50 
hours time-in-service (TIS) and repetitive inspections every 100 hours 
TIS and every 400 hours TIS, by following the instructions in the 
manufacturer's service bulletin. This proposed AD would also prohibit 
installing on any helicopter bellows P/N 105-10113.05, P/N 4619305044, 
and P/N 4638305043 and any gearbox that has these bellows installed.

Differences Between This Proposed AD and the EASA AD

    The EASA AD requires compliance within different time intervals for 
some actions than what this proposed AD would require. The EASA AD 
allows a non-cumulative tolerance of 10 percent that may be applied to 
the compliance times, and this proposed AD would not. The EASA AD 
allows replacing the bellows clamps with cable ties before removing the 
bellows, and this proposed AD would not. This proposed AD would apply 
to Model MBB-BK 117D-2 helicopters while the EASA AD does not. The EASA 
AD applies to Model BO-105D helicopters, while this proposed AD would 
not.

Interim Action

    We consider this proposed AD to be an interim action. The design 
approval holder is currently developing a modification that will 
address the unsafe condition identified in this AD. Once this 
modification is developed, approved, and available, we might consider 
additional rulemaking.

Costs of Compliance

    We estimate that this proposed AD would affect 286 helicopters of 
U.S. Registry and that labor costs would average $85 per work hour. 
Based on these estimates, we expect the following costs:
     Removing and inspecting the swashplate assembly would 
require 3 work-hours. No parts would be needed for a cost of $255 per 
helicopter and $72,930 for the U.S. fleet per inspection cycle.
     Repairing a scratched support tube would require 3 work-
hours. No parts would be needed for a cost of $255 per helicopter.
     Replacing a corroded or damaged clamp would require 2 
work-hours. Parts would cost $8 for a cost of $178 per helicopter.
     Replacing corroded ball bearings would require 4 work-
hours. Parts would cost $3,000 for a cost of $3,340 per helicopter.
     Removing foreign objects from the outer deflection ring 
would require 2 work-hours. No parts would be needed for a cost of $170 
per helicopter.

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
    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.
