Federal Register / Vol. 86, No. 101 / Thursday, May 27, 2021 / Rules and Regulations
The FAA estimates the following costs to do any necessary on-condition actions that would be required based on
the results of any required actions. The FAA has no way of determining the
number of helicopters that might need these on-condition actions:

ESTIMATED COSTS OF ON-CONDITION ACTION
Labor cost
Parts cost
2 work-hours $85 per hour = $170

Up to $970

According to the manufacturer, some or all of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected operators. The FAA does not control warranty coverage for affected operators.
As a result, the FAA has included all known costs in the cost estimate.
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.
