14 CFR Part 39
[Docket No. FAA-2021-0700; Project Identifier 2019-CE-017-AD]
Airworthiness Directives; Costruzioni Aeronautiche Tecnam S.P.A.
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
SUMMARY: The FAA proposes to adopt a new airworthiness directive
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.
DATES: The FAA must receive comments on this proposed AD by October
ADDRESSES: You may send comments, using the procedures found in
11.43 and 11.45, by any of the following methods:
Federal eRulemaking Portal: Go to https://www.regulations.gov. Follow
instructions for submitting comments.

The FAA invites you to send any written relevant data, views, or
arguments about this proposal. Send your comments to an address listed
under ADDRESSES. Include "Docket No. FAA-2021-0700; Project Identifier
2019-CE-017-AD" at the beginning of your comments. The most helpful
comments reference a specific portion of the proposal, explain the
reason for any recommended change, and include supporting 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
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,
Kansas City, MO 64106. Any commentary that the FAA receives which is
not specifically designated as CBI will be placed in the public docket
for this rulemaking.
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
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
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.
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.
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
(1) Is not a "significant regulatory action" under Executive
(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.
