    installed and not marked  "rev. F00": Within 50  hours time-in-service
    after the  effective date  of this  AD or  within 2  months after  the
    effective date of this AD, whichever occurs first, replace any P/N  26
    -8-1408-1 NLG  piston tube  with an  improved part  by installing  NLG
    piston tube kit number SB 288-1.

(2) As of the effective date of this AD, do not install an NLG piston tube
    P/N 26-8-1408-1 on any airplane unless it is marked "rev. F00."

Airworthiness Directives; Costruzioni Aeronautiche Tecnam S.P.A.
Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all
Costruzioni Aeronautiche Tecnam S.P.A. Model P2006T airplanes. This AD
was prompted by mandatory continuing airworthiness information (MCAI)
originated by an aviation authority of another country to identify and
correct an unsafe condition on an aviation product. The MCAI identifies
the unsafe condition as a manufacturing defect in the nose landing gear
(NLG) piston tube. This AD requires replacing the NLG piston tube. The
FAA is issuing this AD to address the unsafe condition on these
products.

DATES: This AD is effective December 3, 2021.

SUPPLEMENTARY INFORMATION:

Background

The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to all Costruzioni
Aeronautiche Tecnam S.P.A. Model P2006T airplanes. The NPRM published
in the Federal Register on August 25, 2021 (86 FR 47422). The NPRM was
prompted by MCAI originated by the European Union Aviation Safety
Agency (EASA), which is the Technical Agent for the Member States of
the European Union. EASA issued AD 2019-0043, dated March 6, 2019
(referred to after this as ``the MCAI''), to correct an unsafe
condition for Costruzioni Aeronautiche Tecnam S.P.A. Model P2006T
airplanes. The MCAI states:

Failures of NLG piston tubes P/N 26-8-1408-1 were reported
during ground operations. Subsequent investigation determined a
deficiency in NLG piston tube manufacturing process. It was also
determined that only a specific batch is affected by this defect.

This condition, if not corrected, could lead to failure of the
NLG, possibly resulting in loss of control on the ground, during or
after landing, with consequent damage to the aeroplane and injury to
occupants.
To address this potential unsafe condition, TECNAM issued the
[service bulletin] SB to provide instructions for the replacement of
each affected part with a part that was manufactured by an improved
process.
For the reasons described above, this [EASA] AD requires removal
from service of the affected parts.

You may examine the MCAI in the AD docket at https://www.regulations.gov
by searching for and locating Docket No. FAA-2021-0700.

Discussion of Final Airworthiness Directive

Comments

The FAA received no comments on the NPRM or on the determination of
the costs.

Conclusion

This product has been approved by the aviation authority of another
country and is approved for operation in the United States. Pursuant to
the FAA's bilateral agreement with this State of Design Authority, it
has notified the FAA of the unsafe condition described in the MCAI and
service information referenced above. The FAA determined that air
safety requires adopting this AD as proposed. Accordingly, the FAA is
issuing this AD to address the unsafe condition on these products. This
AD is adopted as proposed in the NPRM.

Related Service Information

Costruzioni Aeronautiche Tecnam S.P.A. Service Bulletin No. SB 288-
CS-Ed 1, Revision 1, dated December 22, 2017, is related to this AD and
provides information about installing nose landing gear (NLG) piston
tube kit number SB 288-1.

Costs of Compliance

The FAA estimates that this AD affects 59 airplanes of U.S.
registry. The FAA also estimates it will take about 4 work-hours per
airplane to comply with the replacement required by this AD and
required parts would cost about $1,200 per airplane. The average labor
rate is $85 per work-hour.
Based on these figures, the FAA estimates the cost of this AD on
U.S. operators to be $90,860 or $1,540 per airplane.
The FAA has included all known costs in its cost estimate.
According to the manufacturer, however, some of the costs of this AD
may be covered under warranty, thereby reducing the cost impact on
affected operators.

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.
The FAA is 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) Will not affect intrastate aviation in Alaska, 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 Flexibility Act.
