SUPPLEMENTARY INFORMATION: Discussion We are adopting a new airworthiness directive (AD) for Airbus Helicopters Deutschland GmbH (Airbus Helicopters) Model MBB–BK 117 C–2 and MBB–BK 117 D–2 helicopters. This AD requires altering and re-identifying the overhead panel shock mount assembly (shock mount). This AD was prompted by the manufacturer’s stress recalculations. The actions of this AD are intended to correct an unsafe condition on these products. DATES: This AD is effective November 7, 2018. The Director of the Federal Register approved the incorporation by reference SUMMARY: 49791 On June 7, 2018, at 83 FR 26387, 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 Airbus Helicopters Model MBB–BK 117 C–2 and Model MBB–BK 117 D–2 helicopters with an overhead panel shock mount assembly part number (P/N) B246M2035102 or P/N B246M2036101 installed. The NPRM proposed to require installing a retaining plate on the shock mount and re-identifying the shock mount by changing the last three digits of the P/ N to –966. The NPRM also proposed prohibiting the installation of shock E:\FR\FM\03OCR1.SGM 03OCR1 49792 Federal Register / Vol. 83, No. 192 / Wednesday, October 3, 2018 / Rules and Regulations mount P/N B246M2035102 and P/N B246M2036101 on any helicopter. The proposed requirements were intended to prevent failure of a shock mount, which could result in detachment of the overhead panel and injury to occupants during an emergency landing. The NPRM was prompted by AD No. 2017–0026, dated February 14, 2017, issued by EASA, which is the Technical Agent for the Member States of the European Union, to correct an unsafe condition for Airbus Helicopters Model MBB–BK 117 C–2, MBB–BK117 C–2e, MBB–BK 117 D–2, and MBB–BK117 D– 2m helicopters. EASA advises that a recent stress calculation identified that the shock mount may not withstand certification crash loads. EASA states that this condition, if not corrected, could lead to the overhead panel disconnecting during an emergency landing and injuring occupants. Accordingly, the EASA AD requires modifying and re-identifying the shock mounts. 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 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 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 these same type designs 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 applies to Model MBB–BK117 D–2m helicopters, whereas this AD does not since the Model MBB– BK117 D–2m is not FAA typecertificated. This AD also does not include the Model MBB–BK117 C–2(e) in the applicability section because it is a marketing designation and not an FAA type-certificated model. However, this AD applies to those helicopters, as they are Model MBB–BK117 C–2 helicopters. The EASA AD specifies particular helicopter serial numbers (S/Ns) that may not be required to complete some of the requirements of the AD since the specified S/Ns were manufactured with VerDate Sep<11>2014 16:40 Oct 02, 2018 Jkt 247001 shock mounts not affected by the unsafe condition. This AD does not specify particular S/Ns. helicopters identified in this rulemaking action. Related Service Information Under 1 CFR Part 51 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. Airbus Helicopters has issued Alert Service Bulletin (ASB) MBB–BK117 C– 2–24A–015 for Model MBB–BK117 C–2 helicopters and ASB MBB–BK117 D–2– 24A–004 for Model MBB–BK117 D–2 helicopters, both Revision 0 and dated September 14, 2016. This service information contains procedures for altering the shock mounts by installing retaining plates and re-identifying the shock mounts by changing the last three digits of the P/N to –966. 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. Costs of Compliance We estimate that this AD affects 144 helicopters of U.S. Registry. We estimate that operators may incur the following costs in order to comply with this AD. Labor costs are estimated at $85 per work-hour. Installing retaining plates and reidentifying the four shock mounts takes about 3 work-hours and parts cost about $184 for a total estimated cost of $439 per helicopter and $63,216 for the U.S. fleet. According to Airbus Helicopter’s service information, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage by Airbus Helicopters. Accordingly, we have included all costs in our cost estimate. 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 PO 00000 Frm 00024 Fmt 4700 Sfmt 4700 Regulatory Findings List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

SUPPLEMENTARY INFORMATION:

Discussion

    On June 7, 2018, at 83 FR 26387, 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 Airbus Helicopters Model 
MBB-BK 117 C-2 and Model MBB-BK 117 D-2 helicopters with an overhead 
panel shock mount assembly part number (P/N) B246M2035102 or P/N 
B246M2036101 installed. The NPRM proposed to require installing a 
retaining plate on the shock mount and re-identifying the shock mount 
by changing the last three digits of the P/N to -966. The NPRM also 
proposed prohibiting the installation of shock

[[Page 49792]]

mount P/N B246M2035102 and P/N B246M2036101 on any helicopter. The 
proposed requirements were intended to prevent failure of a shock 
mount, which could result in detachment of the overhead panel and 
injury to occupants during an emergency landing.
    The NPRM was prompted by AD No. 2017-0026, dated February 14, 2017, 
issued by EASA, which is the Technical Agent for the Member States of 
the European Union, to correct an unsafe condition for Airbus 
Helicopters Model MBB-BK 117 C-2, MBB-BK117 C-2e, MBB-BK 117 D-2, and 
MBB-BK117 D-2m helicopters. EASA advises that a recent stress 
calculation identified that the shock mount may not withstand 
certification crash loads. EASA states that this condition, if not 
corrected, could lead to the overhead panel disconnecting during an 
emergency landing and injuring occupants. Accordingly, the EASA AD 
requires modifying and re-identifying the shock mounts.

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 
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 
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 these same 
type designs 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 applies to Model MBB-BK117 D-2m helicopters, whereas 
this AD does not since the Model MBB-BK117 D-2m is not FAA type-
certificated. This AD also does not include the Model MBB-BK117 C-2(e) 
in the applicability section because it is a marketing designation and 
not an FAA type-certificated model. However, this AD applies to those 
helicopters, as they are Model MBB-BK117 C-2 helicopters. The EASA AD 
specifies particular helicopter serial numbers (S/Ns) that may not be 
required to complete some of the requirements of the AD since the 
specified S/Ns were manufactured with shock mounts not affected by the 
unsafe condition. This AD does not specify particular S/Ns.

BK117 C-2-24A-015 for Model MBB-BK117 C-2 helicopters and ASB MBB-BK117 
D-2-24A-004 for Model MBB-BK117 D-2 helicopters, both Revision 0 and 
dated September 14, 2016. This service information contains procedures 
for altering the shock mounts by installing retaining plates and re-
identifying the shock mounts by changing the last three digits of the 
P/N to -966.
    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.

Costs of Compliance

    We estimate that this AD affects 144 helicopters of U.S. Registry. 
We estimate that operators may incur the following costs in order to 
comply with this AD. Labor costs are estimated at $85 per work-hour.
    Installing retaining plates and re-identifying the four shock 
mounts takes about 3 work-hours and parts cost about $184 for a total 
estimated cost of $439 per helicopter and $63,216 for the U.S. fleet.
    According to Airbus Helicopter's service information, some of the 
costs of this AD may be covered under warranty, thereby reducing the 
cost impact on affected individuals. We do not control warranty 
coverage by Airbus Helicopters. Accordingly, we have included all costs 
in our cost estimate.

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.
