Airworthiness Directives; Costruzioni Aeronautiche Tecnam srl
Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for
Costruzioni Aeronautiche Tecnam srl Model P2006T airplanes. This AD
results from mandatory continuing airworthiness information (MCAI)
issued by an aviation authority of another country to identify and
correct an unsafe condition on an aviation product. The MCAI describes
the unsafe condition as cracking found in the engine exhaust pipe. We
are issuing this AD to require actions to address the unsafe condition
on these products.

DATES: This AD is effective March 5, 2015.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in the AD as of March 5,
2015.

SUPPLEMENTARY INFORMATION:

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to add an AD that would apply to Costruzioni Aeronautiche
Tecnam srl Model P2006T airplanes. The NPRM was published in the
Federal Register on October 29, 2014 (79 FR 64347). The NPRM proposed
to correct an unsafe condition for the specified products and was based
on mandatory continuing airworthiness information (MCAI) originated by
an aviation authority of another country. The MCAI states:

During a pre-flight inspection of a P2006T aeroplane, which
included the opening of engine nacelle, a crack was found on the
engine exhaust pipe Part Number (P/N) 26-7-1800-1.
This condition, if not detected and corrected, could lead to
engine damage, possibly resulting in damage to the aeroplane and
injury to the occupants.
To address this potential unsafe condition, Costruzioni
Aeronautiche TECNAM issued Service Bulletin (SB) SB 170-CS-Ed 1
Rev1.
For the reason described above, this AD requires a one-time
inspection of the affected engine exhaust pipes and, depending on
findings, replacement.

The MCAI can be found in the AD docket on the Internet at: http://www.regulations.gov/#!documentDetail;D=FAA-2014-0876-0002.

Comments

We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM 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 (79 FR 64347, October 29, 2014) for correcting the unsafe
condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.

Relative Service Information

We reviewed Costruzioni Aeronautiche TECNAM Service Bulletin No. SB
170-CS-Ed 1, Rev 1, dated September 25, 2014. The service bulletin
describes procedures for inspecting and replacing (as necessary) the
engine exhaust pipes. You can find this service information on the
Internet at http://www.regulations.gov by searching for and locating
Docket No. FAA-2014-0876.

Costs of Compliance

We estimate that this AD will affect 10 products of U.S. registry.
We also estimate that it would take about .5 work-hour per product to
comply with the basic requirements of this AD. The average labor rate
is $85 per work-hour.
Based on these figures, we estimate the cost of this AD on U.S.
operators to be $425, or $42.50 per product.
In addition, we estimate that any necessary follow-on actions would
take about .5 work-hour and require parts costing $343, for a cost of
$385.50 per product. We have no way of determining the number of
products that may need these actions.

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. The control
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in
the Costs of Compliance section of this document and includes time for
reviewing instructions, as well as completing and reviewing the
collection of information. Therefore, all reporting associated with
this AD is mandatory. Comments concerning the accuracy of this burden
and suggestions for reducing the burden should be directed to the FAA
at 800 Independence Ave. SW., Washington, DC 20591. ATTN: Information
Collection Clearance Officer, AES-200.

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

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),
(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.

You may examine the AD docket on the Internet at http://www.regulations.gov
by searching for and locating Docket No. FAA-2014-
0876; or in person at the Docket Management Facility between 9 a.m. and
