Airworthiness Directives; Airbus Helicopters Deutschland GmbH 
(Formerly Eurocopter Deutschland GmbH) Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
Airbus Helicopters Deutschland GmbH (Airbus) (formerly Eurocopter 
Deutschland GmbH) Model MBB-BK 117C-2 helicopters with an external 
mounted hoist system wiring harness installed. This proposed AD would 
require inspecting the hoist control pendant wiring harness for 
chafing, and if there is chafing, before the next hoist operation, 
replacing the wiring harness. This proposed AD would also require a 
installing a protection sleeve on the hoist control pendant wiring 
harness. This proposed AD is prompted by an uncommanded hoist release 
involving chafing on the wiring harness of the hoist control pendant 
and on the wiring. The proposed actions are intended to prevent loss of 
an external load or person from the hoist resulting in injury to 
persons being lifted and loss of control of the helicopter.

DATES: We must receive comments on this proposed AD by September 22, 
2015.

ADDRESSES: You may send comments by any of the following methods:
     Federal eRulemaking Docket: Go to http://www.regulations.gov. Follow the online instructions for sending your

Discussion

    EASA, which is the Technical Agent for the Member States of the 
European

[[Page 43971]]

Union, issued EASA AD No. 2014-0211, dated September 19, 2014, to 
correct an unsafe condition for the Airbus Model MBB-BK117 C-2 
helicopters ``equipped with optional equipment external mounted hoist 
system.'' EASA advises that an uncommanded hoist cable cut occurred and 
that an investigation revealed chafing on the wiring harness of the 
hoist control pendant and on the wiring of the +28V wire of the stand-
by horizon inside the middle ceiling panel. The wire of the stand-by 
horizon contacted the hoist control pendant wiring harness and caused 
the uncommanded cable cut. EASA also states that this condition, if not 
detected and corrected, could lead to load release, possibly resulting 
in injury to a human load or to the persons on the ground. EASA issued 
AD No. 2014-0211 requiring an inspection and modification of the wiring 
harness to correct this unsafe condition.

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

    Airbus Helicopters issued Alert Service Bulletin (ASB) MBB-BK117 C-
2-88A-009, Revision 0, on June 18, 2014, specifying a visual inspection 
of the hoist control pendant wiring harness for chafing. If there is 
heavy chafing, before the next hoist operation, the ASB specifies 
replacing the wiring harness. The ASB also specifies a ``retrofit'' of 
an additional protective sleeve for the hoist control pendant wiring 
harness. 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 of this 
NPRM.

Proposed AD Requirements

    This proposed AD would require:
     Before the next hoist operation:
    [cir] Visually inspecting the hoist control pendant wiring harness 
for chafing, and replacing the wiring harness if there is chafing on 
the wiring harness protection sleeve and any internal wiring is 
visible, or if there is chafing on any internal wire.
    [cir] Installing each wiring harness cable tie so that the cable 
tie heads do not contact any adjacent parts or wiring harnesses.
     Within the next 100 hours time-in-service, installing a 
protection sleeve on the wiring harness and inspecting each cable tie 
for correct installation.

Costs of Compliance

    We estimate that this proposed AD would affect 109 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. 
We estimate 1.5 work hours to inspect the hoist control pendant wiring 
harness at a cost of about $128 per helicopter and $13,952 for the 
fleet. We estimate 2 work hours to install a protection sleeve and 
inspect the cable ties and $125 for required parts at a cost of $295 
per helicopter and $32,155 for the fleet. If required, we estimate a 
minimal amount of time for labor and $224 for required parts to replace 
a wiring harness.

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.

2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

Airbus Helicopters Deutschland GmbH (formerly Eurocopter Deutschland 
GmbH): Docket No. FAA-2015-2994; Directorate Identifier 2014-SW-057-
AD.

(a) Applicability

    This AD applies to Model MBB-BK 117 C-2 helicopters with an 
external mounted hoist system wiring harness part number (P/N) 
B851M2063101 installed, certificated in any category.

(b) Unsafe Condition

    This AD defines the unsafe condition as chafing on the wiring 
harness or wiring of a hoist control pendant. This condition could 
result in loss of an external load or person from the hoist 
resulting in injury to persons being lifted and loss of control of 
the helicopter.

(c) Comments Due Date

    We must receive comments by September 22, 2015.

(d) Compliance

    You are responsible for performing each action required by this 
AD within the specified compliance time unless it has already been 
accomplished prior to that time.

(e) Required Actions

    (1) Before the next hoist operation:

there is chafing on the wiring harness protection sleeve such that 
any internal wiring is visible, or if there is chafing on any 
internal wire, replace the wiring harness.
