We propose to adopt a new airworthiness directive (AD) for Airbus Helicopters Deutschland GmbH (Airbus Helicopters) MBB-BK 117 D-2 helicopters. This proposed AD would require repetitively inspecting the bushings of the inner and outer forward trusses of both engines. This proposed AD is prompted by reports of delaminated and worn engine mount bushings. The proposed actions are intended to detect delaminated engine mount bushings, which can lead to excessive vibration, cracking, failure of the engine mount front support pins, and loss of helicopter control.

Airworthiness Directives; Airbus Helicopters Deutschland GmbH

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 Helicopters) MBB-BK 117 D-2 
helicopters. This proposed AD would require repetitively inspecting the 
bushings of the inner and outer forward trusses of both engines. This 
proposed AD is prompted by reports of delaminated and worn engine mount 
bushings. The proposed actions are intended to detect delaminated 
engine mount bushings, which can lead to excessive vibration, cracking, 
failure of the engine mount front support pins, and loss of helicopter 
control.

Discussion

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD No. 2015-0198, dated September 30, 
2015, to correct an unsafe condition for Airbus Helicopters Model MBB-
BK 117 D-2 helicopters. EASA advises that during a pre-flight check of 
an MBB-BK 117 D-2 helicopter, an engine mount bushing was found 
delaminated. More cases of delaminated engine mount bushings were 
reported following additional investigations. According to EASA, this 
condition could lead to cracks and eventually failure of the engine 
mount front support pins, possibly resulting in loss of helicopter 
control.
    The EASA AD consequently requires repetitive inspections of the 
engine mount bushings and depending of the findings, repairing or 
replacing the bushings.

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

    We reviewed Airbus Helicopters Alert Service Bulletin (ASB) MBB-
BK117 D-2-71A-002, Revision 0, dated September 28, 2015, for Model MBB-
BK 117 D-2 helicopters. The ASB introduces repetitive visual 
inspections of the engine mount bushings for defects, deformation, 
separation of the rubber, and missing rubber after reports of 
delaminated engine mount bushings and bushings with damage to the metal 
inner sleeve. If there is any deformation or separation of the rubber, 
the ASB specifies performing a detailed inspection of the bushing in 
accordance with the aircraft maintenance manual.

Proposed AD Requirements

    This proposed AD would require within 50 hours time-in-service 
(TIS) and at intervals not to exceed 50 hours TIS thereafter, visually 
inspecting the bushings of the inner and outer forward trusses of both 
engines, and depending on the outcome of the inspections, replacing or 
repairing the bushings before further flight.

Differences Between This Proposed AD and the EASA AD

    The EASA AD allows for a 10 hour time-in-service, non-cumulative 
tolerance for its required compliance times. This proposed AD would 
not.

Costs of Compliance

    We estimate that this proposed AD would affect 5 helicopters of 
U.S. Registry and that labor costs average $85 per work hour. Based on 
these estimates, we expect the following costs:
     Inspecting the bushings would require 1 work hour. No 
parts would be needed, for a total cost of $85 per helicopter and $425 
for the U.S. fleet.
     Replacing a bushing would require 1 work hour and $373 for 
parts, for a total cost of $458 per bushing.

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.

intervals not to exceed 50 hours TIS:
    (1) Visually inspect each engine mount bushing (bushing) for 
separation of the rubber from the metal or missing rubber.
    (2) If any rubber has separated from the metal or if there is 
missing rubber, inspect the bushing for deformation, corrosion, and 
mechanical damage.
    (i) Replace the bushing with an airworthy bushing if there is 
any deformation, separation of the rubber from the metal, corrosion, 
or mechanical damage, or repair the bushing if the deformation, 
separation of the rubber, corrosion, or mechanical damage is within 
the maximum repair damage limitations.
    (ii) If the inner and outer parts of the bushing are separated 
with missing rubber, replace the bushing with an airworthy bushing.
