Differences Between This AD and the EASA AD
EASA AD 20180006 requires returning and discarding certain parts, whereas this AD requires removing those parts from service instead.
Costs of Compliance The FAA estimates that this AD
affects 4 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.
Inspecting the banjo fittings takes about 8.5 work-hours for an estimated cost of $723 per helicopter and $2,892
for the U.S. fleet. Applying corrosion inhibiting compound takes about 1.5
work-hours for an estimated cost of $128 per helicopter and $512 for the U.S. fleet. If required, replacing a banjo fitting takes a minimal additional amount of time after inspecting it and parts cost about $550 for an estimated cost of $550 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:
Aviation Programs, describes in more 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 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 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.
