We propose to adopt a new airworthiness directive (AD) for Airbus Helicopters Deutschland GmbH (AHD) (previously Eurocopter Deutschland GmbH) Model MBB-BK 117 A-1, A-3, A-4, B-1, B-2, C-1, and C- 2 helicopters. This proposed AD would require an initial and recurring inspection of the N2 control arm and, depending on the outcome of the inspection, repairing or replacing the N2 control arm. This proposed AD is prompted by a report of a heavily corroded and broken N2 control arm. The proposed actions are intended to detect corrosion, a crack, or a scratch in the N2 control arm, which could lead to failure of the N2 control arm, a drop in rotor speed, and subsequent loss of control of the helicopter.

Discussion

EASA, which is the Technical Agent for the Member States of the
European Union, issued EASA AD No. 2013-0154, dated July 22, 2013, to
correct an unsafe condition for Eurocopter Deutschland GmbH (now AHD)
Model MBB-BK117 A-1, A-3, A-4, B-1, B-2, C-1, and C-2 helicopters. EASA
advises of an incident with a Model MBB-BK117 C-2 helicopter that
dropped rotor speed (RPM) within the green range and could not be
recovered to nominal value. According to EASA, an inspection of the
engine N2 control system revealed a heavily corroded and broken N2
control arm. EASA advises that under certain flight conditions and
power demands, a broken N2 control arm can cause a significant and non-
recoverable drop in RPM. As a result, EASA AD No. 2013-0154 requires an
initial and repetitive inspection of the N2 control arm for corrosion,
damage, and scratches, and depending on the outcome of the inspection,
repairing or replacing the N2 control arm.

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

Eurocopter issued Alert Service Bulletin (ASB) MBB-BK117-60A-126
for Model MBB-BK 117 A-1, A-3, A-4, B-1, B-2, and C-1 helicopters, and
ASB MBB-BK117 C-2-6A-005 for Model MBB-BK 117 C-2 helicopters, both
Revision 0, and both dated June 24, 2013. The Eurocopter ASBs specify
inspecting the N2 control arm for corrosion, damage, and scratches and,
depending on the outcome of the inspection, either repairing or
replacing the affected parts. The Eurocopter ASBs also specify
performing the inspection with each 12-month inspection until the N2
inspection requirements are incorporated into the aircraft maintenance
manual. This service information is reasonably available; see ADDRESSES
for ways to access this service information.

Proposed AD Requirements

This proposed AD would require repetitive visual inspections of the
N2 control arm for corrosion, a crack, or a scratch. This proposed AD
would require repairing any N2 control arm with corrosion or a scratch
less than 0.020 inch in depth and replacing any N2 control arm with
exfoliation corrosion, a crack, or with corrosion or a scratch 0.020
inch or greater in depth.

Differences Between This Proposed AD and the EASA AD

The EASA AD allows a noncumulative tolerance of 3 months in the
compliance time for the initial inspection on helicopters with less
than 2 years from the date of first flight and for the repetitive
inspections, and this proposed AD would not.

Costs of Compliance

We estimate that this proposed AD would affect 441 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. Inspecting the N2 control arm would require about one work-
hour for an estimated cost of $85 per helicopter and $37,485 for the
U.S. fleet per inspection cycle. Repairing the N2 control arm would
require about four work-hours for an estimated labor cost of $340.
Replacing the N2 control arm would require about three work-hours for
an estimated labor cost of $255. Parts to replace the N2 control arm
for Model MBB-BK 117 A-1, A-3, A-4, B-1, B-2, and C-1 helicopters would
cost about $2,743 for a total estimated cost of $2,998. Parts to
replace the N2 control arm for a Model MBB-BK 117 C-2 helicopter would
cost about $4,500 for a total estimated cost of $4,755.

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.
