We propose to adopt a new airworthiness directive (AD) for Airbus Helicopters Deutschland GmbH (Airbus Helicopters) Model MBB-BK 117 D-2 helicopters. This proposed AD would require replacing the rescue hoist cable cut pushbutton flip guard (flip guard). This proposed AD is prompted by reports of unintended lifting of several flip guards. The actions of this proposed AD are intended to correct an unsafe condition on these products.

Airworthiness Directives; Airbus Helicopters Deutschland GmbH 
Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

Discussion

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD No. 2017-0038, dated February 22, 
2017 (AD No. 2017-0038), to correct an unsafe condition for Airbus 
Helicopters Models MBB-BK 117 D-2 and MBB-BK 117 D-2m helicopters. The 
EASA AD advises that multiple events were reported of unintended 
lifting of the flip guard and that the flip guard has two stable 
positions, open and closed. AD No. 2017-0038 states that if the 
unintended lifting is not detected, the requirement for dual action 
when activating the rescue hoist cable cut is not guaranteed. According 
to EASA, this condition, if not corrected, could result in inadvertent 
cutting of the rescue hoist cable and subsequent personal injury.
    EASA further advises that Airbus Helicopters has developed an 
improved mono-stable (closed) flip guard, and AD No. 2017-0038 requires 
installing the new flip guard and re-identifying the collective lever 
switch unit.

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

    Airbus Helicopters has issued Alert Service Bulletin No. MBB-BK117 
D-2-67A-002, Revision 0, dated January 23, 2017, which contains 
procedures for replacing flip guard part number (P/N) 79552176 with 
improved flip guard P/N 79553511 and for identifying the collective 
lever switch unit with the Alert Service Bulletin number.

Proposed AD Requirements

    This proposed AD would require before the next hoist operation or 
within

[[Page 43560]]

440 hours time in service (TIS), whichever occurs first, replacing the 
flip guard with flip guard P/N 79553511 on the collective lever switch 
unit.

Differences Between This Proposed AD and the EASA AD

    The EASA AD applies to Model MBB-BK 117 D-2m helicopters; this 
proposed AD would not as these models are not type certificated in the 
U.S. Also, the EASA AD requires compliance within 440 hours TIS, this 
proposed AD would require compliance before the next hoist operation or 
within 440 hours TIS, whichever occurs first. Finally, the EASA AD 
requires identifying the collective lever switch unit with the service 
information number; this proposed AD would not.

Costs of Compliance

    We estimate that this proposed AD would affect 21 helicopters of 
U.S. Registry.
    At an average labor rate of $85 per hour, we estimate that 
operators would incur the following costs in order to comply with this 
proposed AD. Replacing the flip guard would require about 14 hours, and 
required parts would cost $735, for a cost per helicopter of $1,925 and 
a cost of $40,148 to the U.S. fleet.
    According to Airbus Helicopter's 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.
