We propose to supersede Airworthiness Directive (AD) 2017-02- 07 for Airbus Helicopters Deutschland GmbH (Airbus Helicopters) Model MBB-BK 117 C-2 and Model MBB-BK 117 D-2 helicopters. AD 2017-02-07 currently requires a repetitive inspection and a one-time torque of each hydraulic module plate assembly attachment point (attachment point). Since we issued AD 2017-02-07, a terminating action has been developed to address the unsafe condition. This proposed AD would retain the initial inspection and torque requirements of AD 2017-02-07 and require replacing the attachment point hardware. The actions of this proposed AD are intended to prevent an unsafe condition on these products.

Airworthiness Directives; Airbus Helicopters Deutschland GmbH 
Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2017-02-
07 for Airbus Helicopters Deutschland GmbH (Airbus Helicopters) Model 
MBB-BK 117 C-2 and Model MBB-BK 117 D-2 helicopters. AD 2017-02-07 
currently requires a repetitive inspection and a one-time torque of 
each hydraulic module plate assembly attachment point (attachment 
point). Since we issued AD 2017-02-07, a terminating action has been 
developed to address the unsafe condition. This proposed AD would 
retain the initial inspection and torque requirements of AD 2017-02-07 
and require replacing the attachment point hardware. The actions of 
this proposed AD are intended to prevent an unsafe condition on these 
products.

Discussion

    We issued AD 2017-02-07, Amendment 39-18786 (82 FR 10267, February 
10, 2017) (2017-02-07) for Airbus Helicopters Model MBB-BK 117 C-2 
helicopters, serial numbers up to and including 9750, and Model MBB-BK 
117 D-2 helicopters, serial numbers up to and including 20110, with a 
hydraulic module plate assembly part number B291M0003103 with a single 
locking attachment point installed. AD 2017-02-07 requires a repetitive 
inspection and a one-time torque of the attachment points. The actions 
in AD 2017-02-07 are intended to prevent failure of an attachment 
point, loss of the hydraulic module plate, and subsequent loss of 
control of the helicopter.
    EASA, which is the Technical Agent for the Member States of the 
European Union, issued EASA AD No. 2015-0210R1, Revision 1, dated 
October 28, 2015 (2015-0210R1), to correct an unsafe condition for 
Airbus Helicopters Model MBB-BK117 C-2, MBB-BK117 C-2e, MBB-BK117 D-2, 
and MBB-BK117 D-2m helicopters. EASA advised that the hydraulic plate 
assembly on certain MBB-BK117 models has four attachment points on the 
fuselage secured by a single locking mechanism. According to EASA, a 
design reassessment revealed stiffness of the hydraulic plate may be 
insufficient to withstand the in-service loads in the event one of the 
four single locking attachment points fails. EASA stated that if this 
condition is not detected and corrected, it may lead to loss of the 
hydraulic module plate and possible loss of control of the helicopter. 
Therefore, the EASA AD required a repetitive inspection and one-time 
torque tightening of the attachment points in accordance with Airbus 
Helicopters' service information.
    EASA considered its AD an interim action and stated further AD 
action may follow. EASA subsequently revised AD 2015-0210R1 and issued 
AD No. 2015-0210R2, dated December 2, 2016 (2015-0210R2), to exclude 
from the applicability helicopters with an improved double locking 
attachment mechanism that is not subject to the unsafe condition.

Actions Since AD 2017-02-07 Was Issued

    Since we issued AD 2017-02-07, Airbus Helicopters revised its 
service information to add procedures to modify single locking 
attachment mechanisms to double locking attachment mechanisms. EASA 
subsequently superseded AD 2015-0210R2 with AD No. 2017-0047, dated 
March 13, 2017, to require installation of double locking attachments.

FAA's Determination

    These helicopters have been approved by the aviation authority of 
Germany

[[Page 57391]]

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) No. ASB 
MBB-BK117 C-2-29A-003 for Model MBB-BK 117 C-2 helicopters and ASB No. 
ASB MBB-BK117 D-2-29A-001 for Model MBB-BK 117 D-2 helicopters, both 
Revision 2 and both dated February 1, 2017. Until the attachment points 
are modified with double locking attachment mechanisms, this service 
information specifies a repetitive visual inspection for condition and 
correct installation of the attachment points and replacing the 
affected parts if there is a crack. This service information also 
specifies a tightening torque check after the initial inspection and 
replacing the affected parts if torque cannot be applied. This revision 
of the service information also specifies procedures to replace the 
single locking attachment hardware with double locking attachment 
hardware.
    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.

Other Related Service Information

    We also reviewed Airbus Helicopters ASB No. ASB MBB-BK117 C-2-29A-
003 for Model MBB-BK 117 C-2 helicopters and ASB No. ASB MBB-BK117 D-2-
29A-001 for Model MBB-BK 117 D-2 helicopters, both Revision 1 and both 
dated October 14, 2016. Revision 1 of this service information contains 
the same visual inspection and torque tightening check procedures as 
Revision 2. However, Revision 2 of this service information adds the 
procedures to replace the single locking attachment hardware with 
double locking attachment hardware.

Proposed AD Requirements

    This proposed AD would require, within 100 hours time-in-service 
(TIS), unless already done within the last 100 hours TIS, performing a 
visual inspection of each attachment point of the hydraulic module 
plate assembly for a crack and proper installation, and applying torque 
to the nuts of each attachment point. This proposed AD would also 
require, within 300 hours TIS, replacing each single locking attachment 
point mechanism with a double locking attachment point mechanism.

Differences Between This Proposed AD and the EASA AD

    The EASA AD specifies performing the visual inspection of each 
attachment point at intervals not exceeding 400 flight hours. This 
proposed AD would not require a repetitive inspection. This proposed AD 
would require the replacement of each single locking attachment point 
mechanism with a double locking attachment point mechanism within 300 
hours TIS instead, which would make subsequent inspections unnecessary.

Costs of Compliance

    We estimate that this proposed AD would affect 134 helicopters of 
U.S. Registry. We estimate that operators may incur the following costs 
in order to comply with this AD. We estimate the cost of labor at $85 
per work-hour. Visually inspecting the four attachment points would 
take about 0.75 work-hour for an estimated cost of $64 per helicopter 
and $8,576 for the U.S. fleet. Inspecting the torque of the four 
attachment points would take about 0.25 work-hour for an estimated cost 
of $21 per helicopter and $2,814 for the U.S. fleet. Replacing any of 
the attachment point parts would take a minimal amount of time and 
parts would cost about $48 per attachment point. Installing four double 
locking attachment point mechanisms would take a minimal amount of time 
and parts would cost about $400 per helicopter and $53,600 for the U.S. 
fleet.
    According to Airbus Helicopters service information, some of the 
costs of this proposed 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 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.
