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

Issuing agencies

Abstract

The FAA proposes to adopt a new airworthiness directive (AD) for all Costruzioni Aeronautiche Tecnam S.P.A. (Tecnam) Model P2006T airplanes. This proposed AD was prompted by a report of damage on the engine mount structure caused by defective non-conforming engine shock mounts being installed. This proposed AD would require inspecting for the installation of non-conforming engine shock mounts and replacing any non-conforming engine shock mount with an approved part. This proposed AD would also prohibit installation of a non-conforming engine shock mount on any airplane. The FAA is proposing this AD to address the unsafe condition on these products.

data. The FAA will consider all comments received by the closing date 
and may amend this proposal because of those comments.
    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 
<a href="http://regulations.gov">regulations.gov</a>, 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 
Joseph Catanzaro, Aviation Safety Engineer, FAA, 1600 Stewart Avenue, 
Suite 410, Westbury, NY 11590. Any commentary that the FAA receives 
which is 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 2026-0071, dated March 31, 2026 (EASA AD 2026-0071) (also 
referred to as the MCAI), to correct an unsafe condition on Tecnam 
Model P2006T and P2006T NG airplanes. The MCAI states that a report of 
damage on the engine mount structure was caused by non-conforming 
defective engine shock mounts being installed. The unsafe condition, if 
not addressed, could result in the engine disconnecting from the 
airplane structure and loss of control of the airplane. The MCAI 
requires inspecting for the installation of non-conforming engine shock 
mounts and replacing any non-conforming engine shock mount with an 
approved part and prohibits the installation of a non-conforming engine 
shock mount on any airplane.
    You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under 
Docket No. FAA-2026-13799.

Material Incorporated by Reference Under 1 CFR Part 51

    The FAA reviewed Tecnam Service Bulletin SB 969-CS-Ed. 3, Rev. 1, 
dated

[[Page 69731]]

April 3, 2026 (Tecnam SB 969-CS-Ed. 3, Rev. 1). This material specifies 
procedures to inspect and identify non-conforming engine shock mounts 
having part number CONO21-BS and batch number 49-24 or 11-25. Tecnam SB 
969-CS-Ed. 3, Rev. 1 also includes a detailed visual inspection for 
each engine-mount tubular structure associated with any engine on which 
a non-conforming shock mount is detected.
    This material 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.

FAA's Determination

    These products have been approved by the civil aviation authority 
of another country and are approved for operation in the United States. 
Pursuant to the FAA's bilateral agreement with this State of Design 
Authority, that authority has notified the FAA of the unsafe condition 
described in the MCAI and material referenced above. The FAA is issuing 
this NPRM after determining that 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 accomplishing the actions specified 
in the material already described, except as discussed under 
``Differences Between this Proposed AD and the MCAI.'' This proposed AD 
would also require an installation prohibition.

Differences Between This Proposed AD and the MCAI

    The MCAI applies to Model P2006T NG, whereas this AD does not 
because it does not have an FAA type certificate.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 131 airplanes of U.S. registry.
    The FAA estimates the following costs to comply with this proposed 
AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                   Cost per
        Action               Labor cost          Parts cost        product           Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------

                        per hour = $127 (per                    engine).
                        engine).
----------------------------------------------------------------------------------------------------------------

    The FAA estimates the following costs to do any necessary 
replacements that would be required based on the results of the 
proposed inspection. The agency has no way of determining the number of 
airplanes that might need these replacements.

                                               On-condition Costs

 engine).                       $85 per hour =
                                $170 (per
                                engine).
Replace engine mounts........  8 work-hours x    $2,980 (per engine)............  $3,660 (per engine).
                                $85 per hour =
                                $680 (per
                                engine).
----------------------------------------------------------------------------------------------------------------

    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.

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.
