SUPPLEMENTARY INFORMATION:
Discussion
On September 2, 2015, at 80 FR
53030, the Federal Register published
our notice of proposed rulemaking
(NPRM), which proposed to amend 14
CFR part 39 by adding an AD that
would apply to certain MDHI Model
369A (Army OH–6A), 369H, 369HE,
369HM, 369HS, 369D, 369E, 369F,
369FF, and 500N helicopters. The
NPRM proposed to require inspecting
the routing of the fuel pump wiring to
determine whether the fuel pump wire
is properly wrapped around the fuel
inlet hose and correcting the routing of
the wiring if it is not. The NPRM also
proposed to require installing a decal
regarding correct installation of the fuel
pump wiring. The NPRM was prompted
by two accidents and one incident that
occurred on Model 369D helicopters
resulting from an incorrectly positioned
fuel pump wire within the fuel tank
interfering with the operation of the fuel
quantity sensor float, which caused an
erroneous fuel quantity reading in the
cockpit. Because the fuel pump is
installed on all the affected model
helicopters, we are including them in
PO 00000
Frm 00008
Fmt 4700
Sfmt 4700
the applicability. According to MDHI,
because maintenance personnel caused
the incorrect wire routing by failing to
follow procedures for installing the fuel
pump, it is also necessary to install a
decal on the left-hand fuel cell access
cover to refer maintenance personnel to
the appropriate manual procedures. The
proposed requirements were intended to
detect and correct routing of the fuel
pump wiring to prevent interference
with the fuel quantity sensor float, an
erroneous fuel quantity indication in the
cockpit, and subsequent fuel exhaustion
and emergency landing.
Comments
We gave the public the opportunity to
participate in developing this AD, but
we did not receive any comments on the
NPRM (80 FR 53030, September 2,
2015).
FAA’s Determination
We have reviewed the relevant
information and determined that an
unsafe condition exists and is likely to
exist or develop on other products of the
same type designs and that air safety
and the public interest require adopting
the AD requirements as proposed.
Related Service Information Under 1
CFR Part 51
MD Helicopters issued one service
bulletin on April 30, 2014, with five
different numbers: SB369H–255,
SB369E–111, SB500N–049, SB369D–
213, and SB369F–098. The service
bulletin specifies a one-time inspection
of the routing of the fuel pump wire in
the left-hand fuel cell and corrective
action, if necessary. The service bulletin
also specifies installing a warning decal
on the left-hand fuel cell access cover
that refers personnel to the procedures
for routing the fuel pump wire that is
contained in the appropriate
maintenance manual. The service
bulletin states that recent field incidents
have occurred where maintenance
personnel have not followed the
procedures for installation of the fuel
pump. Also, the service bulletin states
that an incorrectly installed fuel pump
wire can interfere with the fuel quantity
sensor float, which can result in
erroneous fuel quantity indications. To
prevent this situation, the service
information states that the fuel pump
wire must be wrapped around the fuel
inlet hose as shown in the applicable
maintenance manual.
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.

Federal Register / Vol. 81, No. 48 / Friday, March 11, 2016 / Rules and Regulations
Costs of Compliance
We estimate that this AD will affect
833 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 fuel
pump wire routing and installing a
decal will take 3 work-hours, and parts
will cost $20 for a total cost of $275 per
helicopter and $229,075 for the U.S.
fleet. If required, rerouting the wiring
will require 1 work-hour for a total cost
of $85 per helicopter.
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
This AD will not have federalism
implications under Executive Order
13132. This AD will 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 above, I
certify that this AD:
(1) Is not a ‘‘significant regulatory
action’’ under Executive Order 12866;
(2) Is not a ‘‘significant rule’’ under
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 AD and placed it in the AD docket.

Discussion
EASA, which is the Technical Agent
for the Member States of the European
Union, has issued EASA AD No. 2015–
0048, dated March 17, 2015, to correct
an unsafe condition for Airbus
Helicopters Model AS 365 N3, EC 155B,
and EC155B1 helicopters. EASA advises
that after installation of a new life raft
on a helicopter, the travel of the life raft
deployment control could not be
properly adjusted, putting at risk proper
life raft inflation. According to a
technical analysis, the varying positions
of the life raft inflation cylinder inside
the bag containing the life raft, as well
as the varying positions of the bag
within the life raft container, may cause
the life raft deployment control cable to
loosen and travel insufficiently.
This condition could result in failure
of the external life raft to deploy after a
ditching, impeding or preventing the
safe evacuation of helicopter occupants,
EASA states. EASA consequently
requires alteration of the life raft
deployment control by installing a
sheath kit, which Airbus Helicopters
identifies as Modification
365A084711.00 and 365A084711.01.
FAA’s Determination
These helicopters have been approved
by the aviation authority of France and
are approved for operation in the United
States. Pursuant to our bilateral
agreement with France, EASA, its
technical representative, has notified us
of the unsafe condition described in the
EASA AD. We are issuing this AD
because we evaluated all information

SUPPLEMENTARY INFORMATION:
Discussion
On September 2, 2015, at 80 FR 53030, the Federal Register
published our notice of proposed rulemaking (NPRM), which proposed to
amend 14 CFR part 39 by adding an AD that would apply to certain MDHI
Model 369A (Army OH-6A), 369H, 369HE, 369HM, 369HS, 369D, 369E, 369F,
369FF, and 500N helicopters. The NPRM proposed to require inspecting
the routing of the fuel pump wiring to determine whether the fuel pump
wire is properly wrapped around the fuel inlet hose and correcting the
routing of the wiring if it is not. The NPRM also proposed to require
installing a decal regarding correct installation of the fuel pump
wiring. The NPRM was prompted by two accidents and one incident that
occurred on Model 369D helicopters resulting from an incorrectly
positioned fuel pump wire within the fuel tank interfering with the
operation of the fuel quantity sensor float, which caused an erroneous
fuel quantity reading in the cockpit. Because the fuel pump is
installed on all the affected model helicopters, we are including them
in the applicability. According to MDHI, because maintenance personnel
caused the incorrect wire routing by failing to follow procedures for
installing the fuel pump, it is also necessary to install a decal on
the left-hand fuel cell access cover to refer maintenance personnel to
the appropriate manual procedures. The proposed requirements were
intended to detect and correct routing of the fuel pump wiring to
prevent interference with the fuel quantity sensor float, an erroneous
fuel quantity indication in the cockpit, and subsequent fuel exhaustion
and emergency landing.
Comments
We gave the public the opportunity to participate in developing
this AD, but we did not receive any comments on the NPRM (80 FR 53030,
September 2, 2015).
FAA's Determination
We have reviewed the relevant information and determined that an
unsafe condition exists and is likely to exist or develop on other
products of the same type designs and that air safety and the public
interest require adopting the AD requirements as proposed.
Related Service Information Under 1 CFR Part 51
MD Helicopters issued one service bulletin on April 30, 2014, with
five different numbers: SB369H-255, SB369E-111, SB500N-049, SB369D-213,
and SB369F-098. The service bulletin specifies a one-time inspection of
the routing of the fuel pump wire in the left-hand fuel cell and
corrective action, if necessary. The service bulletin also specifies
installing a warning decal on the left-hand fuel cell access cover that
refers personnel to the procedures for routing the fuel pump wire that
is contained in the appropriate maintenance manual. The service
bulletin states that recent field incidents have occurred where
maintenance personnel have not followed the procedures for installation
of the fuel pump. Also, the service bulletin states that an incorrectly
installed fuel pump wire can interfere with the fuel quantity sensor
float, which can result in erroneous fuel quantity indications. To
prevent this situation, the service information states that the fuel
pump wire must be wrapped around the fuel inlet hose as shown in the
applicable maintenance manual.
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.

Costs of Compliance
We estimate that this AD will affect 833 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 fuel pump wire routing and installing a decal
will take 3 work-hours, and parts will cost $20 for a total cost of
$275 per helicopter and $229,075 for the U.S. fleet. If required,
rerouting the wiring will require 1 work-hour for a total cost of $85
per helicopter.
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
This AD will not have federalism implications under Executive Order
13132. This AD will 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 above, I certify that this AD:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866;
(2) Is not a ``significant rule'' under 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 AD and placed it in the AD docket.
