Federal Register / Vol. 86, No. 59 / Tuesday, March 30, 2021 / Proposed Rules
Required Actions and Compliance Times in the EASA AD. Service information specified in EASA AD
20180284 that is required for compliance with EASA AD 20180284
will be available on the internet at https www.regulations.gov by searching for and locating Docket No.
FAA20210199 after the FAA final rule is published.
Differences Between This Proposed AD
and the EASA AD
The EASA AD requires contacting Airbus Helicopters or replacing an affected part, where as this proposed AD
would require performing the corrective action in accordance with FAAapproved procedures or removing the affected parts from service instead.
Where the EASA AD specifies a compliance time for the inspection in terms of calendar time or flight hours, this proposed AD would require a compliance time in terms of hours timein-service instead. Where the EASA AD
specifies a compliance time of 15 days for reporting the inspection results, this proposed AD would require that the findings be reported within 30 days.
Interim Action The FAA considers this proposed AD
interim action. If final action is later identified, the FAA might consider further rulemaking then.

Costs of Compliance The FAA estimates that this AD
affects 331 helicopters of U.S. Registry.
Labor rates are estimated at $85 per work-hour. Based on these numbers, the FAA estimates that operators may incur the following costs in order to comply with this proposed AD.
Inspecting the nuts on the MRA
pistons would take about 1 work-hour for an estimated cost of $85 per helicopter and $28,135 for the U.S. fleet.
Replacing the MRA would take about 7 work-hours and parts would cost $325,081 for an estimated cost of $325,676 per helicopter.
Repairing the MRA would take up to about 8 work-hours and parts would cost about $110 for an estimated cost of up to $790 per MRA.
Reporting information would take about 1 hour for an estimated cost of $85 per helicopter and $28,135 for the U.S. fleet.

Reduction Act unless that collection of information displays a current valid OMB control number. The control number for the collection of information required by this proposed AD is 2120
0056. The paperwork cost associated with this proposed AD has been detailed in the Costs of Compliance section of this document and includes time for reviewing instructions, as well as completing and reviewing the collection of information. Therefore, all reporting associated with this proposed AD is mandatory. Comments concerning the accuracy of this burden and suggestions for reducing the burden should be directed to Information Collection Clearance Officer, Federal Aviation Administration, 10101
Hillwood Parkway, Fort Worth, TX
761771524.
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 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 above, I
certify this proposed regulation:
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.
