Federal Register/Vol. 75, No. 98/Friday, May 21, 2010/Rules and Regulations
this increase in the specified hourly
Costs of Compliance
Based on the service information, we
estimate that this AD will affect about
120 products of U.S. registry.
The actions that are required by AD
2007-03-05 and retained in this AD
take about 1 work-hour per product, at
an average labor rate of $85 per work
hour. Based on these figures, the
estimated cost of the currently required
actions is $85 per product.
We estimate that it will take about 60
additional work-hours per product to
comply with the new basic
requirements of this AD. Required parts
will cost about $600 per product. The
average labor rate is $85 per work-hour.
Where the service information lists
required parts costs that are covered
under warranty, we have assumed that
there will be no charge for these costs.
As we do not control warranty coverage
for affected parties, some parties may
incur costs higher than estimated here.
Based on these figures, we estimate the
cost of the AD on U.S. operators to be
$684,000, or $5,700 per product.
Authority for This Rulemaking
Title 49 of the United States Code
specifies the FAA's 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 Agency's
We are 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
We determined that 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 this AD:
1. Is not a "significant regulatory
action" under Executive Order 12866;
2. Is not a "significant rule" under the
DOT Regulatory Policies and Procedures
(44 FR 11034, February 26, 1979); 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
We prepared a regulatory evaluation
of the estimated costs to comply with
this AD and placed it in the AD docket.
