Airworthiness Directives; Costruzioni Aeronautiche Tecnam srl
Airplanes

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

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for
certain Costruzioni Aeronautiche Tecnam srl Model P2006T airplanes.
This proposed AD results from mandatory continuing airworthiness
information (MCAI) originated by an aviation authority of another
country to identify and address an unsafe condition on an aviation
product. The MCAI describes the unsafe condition as an incorrect part
number for the rudder trim actuator is referenced in the Airworthiness
Limitations section of the FAA-approved maintenance program (e.g.,
maintenance manual) and the life limit for that part may not be
properly applied in service. We are issuing this proposed AD to require
actions to address the unsafe condition on these products.

DATES: We must receive comments on this proposed AD by May 3, 2018.

ADDRESSES: You may send comments by any of the following methods:

Federal eRulemaking Portal: Go to http://www.regulations.gov. Follow the

Discussion

The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Community, has issued AD
No. 2018-0029, dated January 31, 2018 (referred to after this as "the
MCAI"), to address an unsafe condition for the specified products. The
MCAI states:

It was identified that the Part Number (P/N) of the rudder trim
actuator mentioned in the P2006T Aircraft Maintenance Manual (AMM)
Airworthiness Limitations Section (ALS) document was erroneously
mentioned. As a result, it cannot be excluded that the life limit
applicable to this actuator is not being applied in service.

This condition, if not corrected, could lead to failure of the
rudder control system, possibly resulting in reduced control of the
aeroplane.

To address this potential unsafe condition, TECNAM published
Service Bulletin (SB)-285-CS Ed. 1 Rev. 0 (later revised) to inform
operators about this typographical error. It is expected that,
during the next revision of the P2006T AMM ALS document, it will
list the correct the P/N for that rudder trim actuator.

For the reason described above, this [EASA] AD requires
implementation of a life limit for rudder trim actuator.

You may examine the MCAI on the internet at http://www.regulations.gov
by searching for and locating Docket No. FAA-2018-0204.

Related Service Information Under 1 CFR Part 51

Costruzioni Aeronautiche Tecnam srl has issued Service Bulletin No.
SB 285-CS-Ed 1, Revision 2, dated February 2, 2018. The service
information describes procedures for correcting the part number of the
rudder trim actuator in the Airworthiness Limitations section of the
FAA-approved maintenance program (e.g., maintenance manual). This
service information is reasonably available because the interested
parties have access to it through their normal course of business or by
the means identified in the ADDRESSES section of this NPRM.

FAA's Determination and Requirements of the Proposed AD

This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to our bilateral agreement with this State of Design Authority, they
have notified us of the unsafe condition described in the MCAI and
service information referenced above. We are proposing this AD because
we evaluated all information and determined the unsafe condition exists
and is likely to exist or develop on other products of the same type
design.

Costs of Compliance

We estimate that this proposed AD will affect 20 products of U.S.
registry. We also estimate that it would take about 1 work-hour per
product to comply with the proposed requirement to incorporate a
correction to the Airworthiness Limitations section of the FAA-approved
maintenance program (e.g., maintenance manual). The average labor rate
is $85 per work-hour.

Based on these figures, we estimate the cost of this proposed AD on
U.S. operators to be $1,700, or $85 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
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.

This AD is issued in accordance with authority delegated by the
Executive Director, Aircraft Certification Service, as authorized by FAA
Order 8000.51C. In accordance with that order, issuance of ADs is normally
a function of the Compliance and Airworthiness Division, but during this
transition period, the Executive Director has delegated the authority
to issue ADs applicable to small airplanes, gliders, balloons,
airships, domestic business jet transport airplanes, and associated
appliances to the Director of the Policy and Innovation Division.

Regulatory Findings

We determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 proposed
regulation:

(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.
