information also specifies procedures required to install the improved fuel supply hose.
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 Alert Service Bulletin No.
EC22571A019, Revision 1, dated February 28, 2019, which also specifies procedures for removing the fuel supply hose, visually inspecting the fuel supply hose for twisting, performing an endoscope inspection on the inside of the hose, and specifies procedures required to install a serviceable fuel supply hose.
Differences Between This AD and EASA
AD 20210156
EASA AD 20210156 requires compliance within 110 flight hours or 6
months, whichever occurs first after the effective date of EASA AD 20190092, while this AD requires compliance within 110 hours time-in-service after the effective date of this AD. EASA AD
20210156 requires reporting information to Airbus Helicopters if the LH fuel supply hose is twisted on the inside, while this AD does not.
Additionally, EASA AD 20210156 is applicable to all serial-numbered EC225LP helicopters, whereas this AD
applies to EC225LP helicopters with a certain LH fuel supply hose installed.

Costs of Compliance The FAA estimates that this AD
affects 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 AD.
Visually inspecting the LH fuel supply hose for twisting takes about 1
work-hour for an estimated cost of $85
per helicopter and $2,380 for the U.S.
fleet.
Replacing a LH fuel supply hose takes about 8 work-hours and parts cost about $2,363 for an estimated replacement cost of $3,043 per replacement.
Borescope inspecting the LH fuel supply hose takes about 8 work-hours for an estimated cost of $680 per helicopter.
Authority for This Rulemaking Title 49 of the United States Code specifies the FAAs authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. Subtitle VII:

detail the scope of the Agencys 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 helicopters 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 Will not affect intrastate aviation in Alaska, and 3 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.

b Affected ADs None.
c Applicability This AD applies to Airbus Helicopters Model EC225LP helicopters, certificated in any category, with a left-hand side LH
engine fuel supply fuel supply hose part number P/N 704A34416087 installed.
d Subject Joint Aircraft Service Component JASC
Code: 2820, Aircraft Fuel Distribution System.
e Unsafe Condition This AD was prompted by a report of an incorrect installation of the LH fuel supply hose P/N 704A34416087. The FAA is issuing this AD to prevent restricted fuel flow to the LH engine. The unsafe condition, if not addressed, could result in a decrease of the LH engine power when accelerating to a power setting corresponding to One Engine Inoperative power and subsequent reduced control of the helicopter.
f Compliance Comply with this AD within the compliance times specified, unless already done.
g Required Actions 1 Within 110 hours time-in-service TIS
after the effective date of this AD, visually inspect the LH fuel supply hose for twisting as shown in Figures 1 and 2 of Airbus Helicopters Alert Service Bulletin No.
