AGENCY: Federal Aviation Administration
(FAA), DOT.
ACTION: Final rule.
SUMMARY: We are adopting a new airworthiness directive (AD) for
certain
Cirrus Design Corporation (Cirrus) Model SR22T airplanes. This AD was
prompted by reports of partial loss of engine power due to a dislodged
rubber gasket/seal being ingested into the turbocharger. This AD
requires inspection and modification of the air box flange welds and
slots and installation of induction system air box seals as applicable.
We are issuing this AD to correct the unsafe condition on these
products.
DATES: This AD is effective February 29, 2012.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in the AD as of February 29,
2012.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would apply to the specified products.
That NPRM published in the Federal Register on November 2, 2011 (76 FR
67631). That NPRM proposed to require inspection and modification of
the air box flange welds and slots and installation of induction system
air box seals as applicable.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (76 FR 67631, November 2,
2011) or on the determination of the cost to the public.
Conclusion
We reviewed the relevant data and determined that air safety and
the public interest require adopting the AD as proposed except for
minor editorial changes. We have determined that these minor changes:
Are consistent with the intent that was proposed in the
NPRM (76 FR 67631, November 2, 2011) for correcting the unsafe
condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.
Costs of Compliance
We estimate that this AD affects 67 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:
Estimated Costs
|
Action
|
Labor cost
|
Parts cost
|
Cost per
product
|
Cost on
U.S.
operators
|
| Replacement of the induction
system air box seals and extension of air box flange slots. |
2.5 work-hours x $85 per
hour = $212.50. |
$139
|
$351.50
|
$23,550.50
|
According to the manufacturer, all
of the costs of this AD may be
covered under warranty, thereby reducing the cost impact on affected
individuals. We do not control warranty coverage for affected
individuals. As a result, we have included all costs in our cost
estimate.
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 authority.
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 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) Is not a ``significant rule'' under DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979),
(3) Will not affect intrastate aviation in Alaska, and
(4) 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.
List of Subjects in 14 CFR Part 39

reference, Safety.
