Table does not include estimated costs for reporting.

The FAA estimates that it takes 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 $1,785, or $85 per product.
The FAA estimates the following costs to do any necessary on-condition
repairs that are required based on the results of any required actions. The FAA
has no way of determining the number of aircraft that might need these oncondition repairs:

ESTIMATED COSTS OF ON-CONDITION ACTIONS
Labor cost
Parts cost
Up to 42 work-hours $85 per hour = Up to $3,570 per door

$0

Cost per product Up to $3,570 per door.

The FAA has received no definitive data on which to base the parts cost estimates for the on-condition repairs specified in this AD.

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.
Paperwork Reduction Act A federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB control number.

Jkt 253001

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.

The FAA is issuing this AD to address damage from false drill starts, which could result in reduced structural integrity of the airplane.
