14 CFR Part 39

[Docket No. FAA-2018-0204; Product Identifier 2018-CE-003-AD; Amendment
39-19339; AD 2018-15-07] RIN 2120-AA64

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 certain
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 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 AD to require actions to address the unsafe condition on
these products.

DATES: This AD is effective September 4, 2018.

SUPPLEMENTARY INFORMATION:

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would apply to Costruzioni Aeronautiche
Tecnam srl Model P2006T airplane. The NPRM was published in the Federal
Register on March 19, 2018 (83 FR 11903). The NPRM proposed to correct
an unsafe condition for the specified products and was based on
mandatory continuing airworthiness information (MCAI) originated by the
European Aviation Safety Agency (EASA), which is the Technical Agent
for the Member States of the European Community. 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.

The MCAI can be found in the AD docket on the internet at https://www.regulations.gov/document?D=FAA-2018-0204-0002.

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.

Changes Made to This AD

We changed the incorporation by reference of the service
information for adding a life limit to the Airworthiness Limitations
section of the maintenance program to only a reference. The service
information does not provide any specific procedures or instructions
for establishing the life limit.
We also inadvertently omitted information for ``Contacting the
Manufacturer,'' which is a standard paragraph for FAA ADs related to
MCAIs. We have added that paragraph in the final rule as paragraph
(g)(2).

Conclusion

We reviewed the relevant data and determined that air safety and
the public interest require adopting the AD as proposed except for the
changes stated above and other minor editorial changes. We have
determined that these minor changes:
Are consistent with the intent that was proposed in the
NPRM for correcting the unsafe condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.

Related Service Information

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).

Costs of Compliance

We estimate that this AD will affect 20 products of U.S. registry.
We also estimate that it will take about 1 work-hour per product to
comply with this 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 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 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.
