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

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for all Costruzioni Aeronautiche Tecnam S.P.A. Model P2006T airplanes. 
This proposed 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 describes the unsafe condition as a manufacturing 
defect in the nose landing gear (NLG) piston tube. This proposed AD 
would require replacing the NLG piston tube. The FAA is proposing this 
AD to address the unsafe condition on these products.

    Except for Confidential Business Information (CBI) as described in 
the following paragraph, and other information as described in 14 CFR 
11.35, the FAA will post all comments received, without change, to 
https://www.regulations.gov, including any personal information you 
provide. The agency will also post a report summarizing each 
substantive verbal contact received about this NPRM.

Confidential Business Information

    CBI is commercial or financial information that is both customarily 
and actually treated as private by its owner. Under the Freedom of 
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public 
disclosure. If your comments responsive to this NPRM contain commercial 
or financial information that is customarily treated as private, that 
you actually treat as private, and that is relevant or responsive to 
this NPRM, it is important that you clearly designate the submitted 
comments as CBI. Please mark each page of your submission containing 
CBI as ``PROPIN.'' The FAA will treat such marked submissions as 
confidential under the FOIA, and they will not be placed in the public 
docket of this NPRM. Submissions containing CBI should be sent to Jim 
Rutherford, Aviation Safety Engineer, General Aviation & Rotorcraft 
Section, International Validation Branch, FAA, 901 Locust, Room 301,

not specifically designated as CBI will be placed in the public docket 
for this rulemaking.

Background

    The European Union Aviation Safety Agency (EASA), which is the 
Technical Agent for the Member States of the European Union, has issued 
EASA AD 2019-0043, dated March 6, 2019 (referred to after this as ``the 
MCAI''), to correct an unsafe condition on 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.

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 NPRM 
and provides information about installing nose landing gear (NLG) 
piston tube kit number SB 288-1.

FAA's Determination

    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 is issuing this NPRM 
after determining the unsafe condition described previously is likely 
to exist or develop on other products of the same type design.

Proposed AD Requirements in This NPRM

    This proposed AD would require replacing NLG piston tubes that are 
not P/N 26-8-1408-1 and marked ``rev F00.''

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 59 airplanes of U.S. registry. The FAA also estimates that it 
would take about 4 work-hours per airplane to comply with the 
replacement required by this proposed AD. The average labor rate is $85 
per work-hour. Required parts would cost about $1,200 per airplane.
    Based on these figures, the FAA estimates the cost of this proposed 
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 
proposed 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.

[[Page 47424]]

Regulatory Findings

    The FAA 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) Would not affect intrastate aviation in Alaska, and
    (3) Would not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
