Abstract
The FAA proposes to supersede Airworthiness Directive (AD) 2021-05-03, which applies to certain Airbus Helicopters Model EC225LP helicopters. AD 2021-05-03 requires various inspections of a certain part-numbered left-hand (LH) engine fuel supply (fuel supply) hose and depending on the inspection results, reinstalling or removing the fuel supply hose from service. AD 2021-05-03 also requires installing an improved part and prohibits installing an affected fuel supply hose on any helicopter unless it is installed by following certain procedures. Since the FAA issued AD 2021-05-03, there were reports of difficulties using an adjusting tool to install the improved fuel supply hose. This proposed AD would continue to require the actions of 2021-05-03 and expand the applicability, expand the parts installation limitations, and require using an improved adjusting tool and updated procedures. This proposed AD would also update certain compliance times and clarify certain requirements. The FAA is proposing this AD to address the unsafe condition on these products.

Airworthiness Directives; Airbus Helicopters
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD)
2021-05-03, which applies to certain Airbus Helicopters Model EC225LP
helicopters. AD 2021-05-03 requires various inspections of a certain
part-numbered left-hand (LH) engine fuel supply (fuel supply) hose and
depending on the inspection results, reinstalling or removing the fuel
supply hose from service. AD 2021-05-03 also requires installing an
improved part and prohibits installing an affected fuel supply hose on
any helicopter unless it is installed by following certain procedures.
Since the FAA issued AD 2021-05-03, there were reports of difficulties
using an adjusting tool to install the improved fuel supply hose. This
proposed AD would continue to require the actions of 2021-05-03 and
expand the applicability, expand the parts installation limitations,
and require using an improved adjusting tool and updated procedures.
This proposed AD would also update certain compliance times and clarify
certain requirements. The FAA is proposing this AD to address the
unsafe condition on these products.

Background
The FAA issued AD 2021-05-03, Amendment 39-21864 (86 FR 72824,
December 23, 2021) (AD 2021-05-03), for certain Airbus Helicopters
Model EC225LP helicopters. AD 2021-05-03 requires visually inspecting a
certain part-numbered LH fuel supply hose for twisting, and if needed,
borescope inspecting the entire length of the inside of the fuel supply
hose for twisting. Depending on the inspection results, AD 2021-05-03
requires reinstalling or removing the fuel supply hose from service.
Additionally, AD 2021-05-03 prohibits installing that part-numbered LH
fuel supply hose on any helicopter unless that LH fuel supply hose is
installed by following certain procedures described in the
manufacturer's service bulletin. Finally, AD 2021-05-03 also requires
modifying your helicopter by removing LH fuel supply hose part number
(P/N) 704A34416087 from service and installing the improved LH fuel
supply hose P/N 704A34416101.
AD 2021-05-03 was prompted by EASA AD 2021-0156, dated July 2, 2021
(EASA AD 2021-0156), which superseded EASA AD 2019-0092, dated April
26, 2019 (EASA AD 2019-0092), issued by EASA, which is the Technical
Agent for the Member States of the
[[Page 23587]]
European Union, to correct an unsafe condition for all Airbus
Helicopters Model EC 225 LP helicopters. EASA initially advised of a
report that an LH side engine experienced a power loss during an in-
flight single engine power check. EASA stated that a subsequent
investigation determined that the fuel flow to the affected engine was
restricted by a twisted fuel supply hose. EASA later advised that
Airbus Helicopters had developed an improved fuel supply hose P/N
704A34416101 and modification instructions to install the improved
part. This condition, if not addressed, could lead to a decrease of the
LH engine power when accelerating to the power setting corresponding to
One Engine Inoperative power and subsequent reduced control of the
helicopter.
EASA AD 2021-0156 retained the requirements of EASA AD 2019-0092
and required replacing the affected part with the improved part. EASA
AD 2021-0156 also allowed a terminating action for the inspection
requirements once the improved part had been installed according to the
installation requirements.
Actions Since AD 2021-05-03 Was Issued
Since the FAA issued AD 2021-05-03, EASA issued AD 2022-0087, dated
May 16, 2022 (EASA AD 2022-0087) to supersede EASA AD 2021-0156. EASA
advises of difficulties that were reported during installation of the
improved LH fuel supply hose due to using an inappropriately shaped
adjusting tool. Accordingly, EASA AD 2022-0087 retains the requirements
of EASA AD 2021-0156 and requires replacing the affected part with the
improved part by following updated modification instructions and using
an improved adjusting tool. The updated modification instructions also
specify updated torque values for the junction nuts and re-tightening
instructions for helicopters modified with previous instructions. EASA
AD 2022-0087 requires a repetitive inspection for fuel leakage for
those helicopters modified with previous instructions and considers the
re-tightening of the junction nuts of the improved part as terminating
action for the repetitive inspection requirements.
Accordingly, this proposed AD would expand the applicability of AD
2021-05-03 by adding LH fuel supply hose P/N 704A34416101. The FAA also
determined to update certain compliance times by adding calendar
compliance times to factor in varying fleet usage and clarified the
actions in paragraphs (g)(1)(i) and (ii) of AD 2021-05-03. This
proposed AD also updates the parts installation limitations for LH fuel
supply hose P/N 704A34416087 and adds parts installation limitations
for LH fuel supply hose P/N 704A34416101. Lastly, this NPRM updates the
Costs of Compliance section by correcting the number of work-hours to
replace an LH fuel supply hose.
FAA's Determination
These helicopters been approved by EASA and are approved for
operation in the United States. Pursuant to the FAA's bilateral
agreement with the European Union, EASA has notified the FAA about the
unsafe condition described in its AD. The FAA is proposing this AD
after evaluating all known relevant information and determining that
the unsafe condition described previously is likely to exist or develop
on other helicopters of the same type design.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Airbus Helicopters Alert Service Bulletin (ASB)
No. EC225-28A026, Revision 1, dated May 6, 2022 (ASB EC225-28A026 Rev
1), which specifies procedures for modifying the adjusting tool and
replacing the LH fuel supply hose by using the modified adjusting tool.
ASB EC225-28A026 Rev 1 also specifies updated allowable torque limits
for the junction nuts and, for helicopters that have previously
accomplished Airbus Helicopters ASB No. EC225-28A026, Revision 0, dated
May 21, 2021, ASB EC225-28A026 Rev 1 specifies procedures to
repetitively inspect the junction nuts for fuel leakage until the LH
engine is removed and the updated allowable torque limit is applied to
the junction nuts.
This proposed AD would also require Airbus Helicopters ASB No.
EC225-71A019, Revision 2, dated May 21, 2021, which the Director of the
Federal Register approved for incorporation by reference as of January
27, 2022 (86 FR 72824, December 23, 2021).
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.
Other Related Service Information
The FAA also reviewed Airbus Helicopters ASB No. EC225-71A019,
Revision 1, dated February 28, 2019. This service information specifies
procedures for removing the fuel supply hose from the LH power plant,
visually inspecting the fuel supply hose for twisting, and depending on
inspection results, performing an endoscope inspection on the inside of
the hose.
Proposed AD Requirements in This NPRM
For helicopters with LH fuel supply hose P/N 704A34416087
installed, this proposed AD would require visually inspecting the LH
fuel supply hose for twisting, and if needed, borescope inspecting the
entire length of the inside of the fuel supply hose for twisting.
Depending on the inspection results, this proposed AD would require
reinstalling or removing the fuel supply hose from service. This
proposed AD would also require modifying your helicopter by removing LH
fuel supply hose P/N 704A34416087 from service and installing improved
LH fuel supply hose P/N 704A34416101 using updated procedures.
Additionally, for helicopters modified with the improved LH fuel supply
hose P/N 704A34416101 using previous procedures or if the installation
procedures cannot be determined, this proposed AD would require
repetitive inspections for fuel leakage and, depending on the results,
tightening the junction nuts of this improved fuel supply hose with the
LH side engine removed. Tightening the junction nuts would provide
terminating action for the repetitive fuel leakage inspections. Lastly,
this proposed AD would require installation limitations for LH fuel
supply hose P/N 704A34416087 and LH fuel supply hose P/N 704A34416101.
Differences Between This Proposed AD and the EASA AD
EASA AD 2022-0087 is applicable to all serial-numbered Model
EC225LP helicopters, whereas this proposed AD would apply to Model
EC225LP helicopters with certain part-numbered LH fuel supply hoses
installed.
For helicopters modified with LH fuel supply hose P/N 704A34416101
in accordance with previous instructions or by installation of AH
modification 0728745 prior to initial delivery of the helicopter from
the manufacturer, EASA AD 2022-0087 requires re-tightening the junction
nuts to the new torque values during the next (re)installation of the
LH engine or of the improved fuel supply hose, whereas this proposed AD
would require that action within 110 hours time-in-service with the LH
side engine removed for helicopters with LH fuel supply hose P/N
704A34416101 installed with previous instructions, by installation of
AH modification 0728745 prior to initial delivery of the helicopter
from the manufacturer, or if the previously accomplished installation
procedures cannot be determined. Also, for those helicopters, depending
on the interim fuel leakage inspection results,
[[Page 23588]]
EASA AD 2022-0087 requires corrective action in accordance with
approved maintenance instructions, whereas this proposed AD would
require tightening the junction nuts to the new torque values with the
LH engine removed.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect up to 28 helicopters of U.S. Registry. Labor rates are estimated
at $85 per work-hour. Based on these numbers, the FAA estimates the
following costs to comply with this proposed AD.
Visually inspecting the LH fuel supply hose for twisting would take
about 1 work-hour for an estimated cost of $85 per helicopter and
$2,380 for the U.S. fleet. Borescope inspecting the LH fuel supply hose
would take about 8 work-hours for an estimated cost of $680 per
helicopter.
Replacing an LH fuel supply hose would take up to 11 work-hours and
parts would cost about $2,363 for an estimated replacement cost of
$3,298 per replacement.
Inspecting for fuel leakage would take about 1 work-hour for an
estimated cost of $85 per helicopter, per inspection cycle. Removing
the LH engine and tightening the LH fuel supply hose fittings would
take 8 work-hours for an estimated cost of $680 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.
The FAA is 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
The FAA 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) Would not affect intrastate aviation in Alaska, and
(3) Would not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
