Federal Register / Vol. 86, No. 171 / Wednesday, September 8, 2021 / Rules and Regulations
requirements in an AD is impracticable to demonstrate or track on an ongoing basis; therefore, a requirement to operate the aircraft in such a manner is unenforceable. Nonetheless, the FAA
recommends that flight crews of the helicopters listed in the applicability operate in accordance with the revised
emergency procedures mandated by this AD.
Interim Action The FAA considers this 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 28 helicopters of U.S. registry.
The FAA estimates the following costs to comply with this AD:

ESTIMATED COSTS FOR REQUIRED ACTIONS
Parts cost
Action
Labor cost
New actions

Up to 6 work-hours $85 per hour =
$510.

Cost per product $0

Up to $510

Cost on U.S.
operators Up to $14,280.

Table does not include estimated costs for reporting.

The FAA estimates that it will take about 1 work-hour per product to comply with the reporting requirement in this AD. The average labor rate is $85
per hour. Based on these figures, the
FAA estimates the cost of reporting the inspection results on U.S. operators to be $2,380, or $85 per product.
The FAA estimates the following costs to do any necessary on-condition
actions that will 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 ACTIONS
Labor cost
Parts cost
Cost per product
40 work-hours $85 per hour = $3,400

$295,000

$298,400

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
