Airworthiness Directives; SOCATA Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for SOCATA
Model TBM 700 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
installation of an incorrect part number during overhaul of the nose
landing gear. We are issuing this AD to require actions to address the
unsafe condition on these products.
DATES: This AD is effective July 23, 2012.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of July 23, 2012.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would apply to the specified products.
That NPRM was published in the Federal Register on March 9, 2012 (77 FR
14314). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
A TBM 700 operator reported a case of rupture of the bolt
attaching the actuator hinge axle on the NLG of the aeroplane. The
results of the technical investigations carried out by SOCATA
revealed that this rupture could have been caused by the
installation of a bolt bearing incorrect Part Number (P/N) during
overhaul of the NLG. Furthermore, the investigations led to identify
the NLG part numbers identified by S/N which are potentially
affected after repair or overhaul.
This condition, if not detected and corrected, could lead to
partial disengagement of the actuator hinge axle on the NLG of the
aeroplane, resulting in nose landing gear collapse, possibly
resulting in structural damage to the aeroplane.
To address this condition, SOCATA have developed Service
Bulletin SB 70-194-32 which gives instructions for accomplishing
repetitive checks of the bolt attaching actuator hinge axle on NLG
and for replacing
[[Page 36126]]
the bolt attaching the actuator hinge axle with a correct bolt P/N.
For the reasons described above, this AD requires accomplishment
of repetitive checks of potentially affected NLGs and replacement of
the bolt attaching the actuator hinge axle with a serviceable bolt.
This AD also prohibits installation on any aeroplane of a
potentially affected NLG, unless the bolt attaching the actuator
hinge axle has been replaced with a serviceable bolt and the NLG has
been marked with a green varnish line.
Following issuance of EASA AD 2011-0225-E, it has been
determined that further NLG P/Ns and S/Ns are affected by this AD.
SOCATA have developed an erratum to SB 70-194-32 amendment 2, which
lists the new P/Ns and S/Ns as well affected by this AD.
For the above reason, this AD, which supersedes EASA AD 2011-
0225-E, retaining its requirements, extends the list of NLG P/Ns and
S/Ns affected by the AD requirements.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (77 FR 14314, March 9,
2012) or on the determination of the cost to the public.
Conclusion
We reviewed the relevant data and determined that air safety and
the public interest require adopting the AD as proposed except for
minor editorial changes. We have determined that these minor changes:
Are consistent with the intent that was proposed in the
NPRM (77 FR 14314, March 9, 2012) for correcting the unsafe condition;
and
Do not add any additional burden upon the public than was
already proposed in the NPRM (77 FR 14314, March 9, 2012).
Costs of Compliance
We estimate that this AD will affect 448 products of U.S. registry.
We also estimate that it would take about 1 work-hour per product to
comply with the basic requirements of this AD. The average labor rate
is $85 per work-hour. Required parts would cost about $35 per product.
Based on these figures, we estimate the cost of the AD on U.S.
operators to be $53,760, or $120 per product.
According to the manufacturer, some of the costs of this AD may be
covered under warranty, thereby reducing the cost impact on affected
individuals. We do not control warranty coverage for affected
individuals. As a result, we have included all costs in our cost
estimate.
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.
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.
Examining the AD Docket
You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Management Facility
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The AD docket contains the NPRM, the regulatory evaluation,
any comments received, and other information. The street address for
the Docket Office (telephone (800) 647-5527) is in the ADDRESSES
section. Comments will be available in the AD docket shortly after
receipt.

PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new AD:
2012-10-14 SOCATA: Amendment 39-17063; Docket No. FAA-2012-0250;
Directorate Identifier 2011-CE-043-AD.
(a) Effective Date
This airworthiness directive (AD) becomes effective July 23,
2012.
(b) Affected ADs
None.
(c) Applicability
This AD applies to SOCATA Model TBM 700 airplanes, all serial
numbers (S/N), certificated in any category, equipped with one of
the following landing gears:
(1) Part number (P/N) D23766000 or D23766000-X, serial numbers
(S/N) B001 through B373; B375; AR1000 through AR1023; AR1025 through
AR1031; AR1033 through AR1036; AAB00000A through AAB13766Z; AAB00000
through AAB13766; and EURXXX; or
(2) P/N 21130-001-XY or 21130-000-XY, all S/N.
(d) Subject
Air Transport Association of America (ATA) Code 32: Landing
Gear.
(e) Reason
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 describes the unsafe condition as installation of
an incorrect part number during overhaul of the nose landing gear.
We are issuing this AD to detect and correct installation of
incorrect P/N NLG bolts, which if not corrected could result in NLG
collapse with consequent structural damage to the airplane.
(f) Actions and Compliance
Unless already done, do the following actions using the
Accomplishment Instructions of DAHER-SOCATA TBM Aircraft Mandatory
Service Bulletin SB 70-194-32, Amendment 2, dated November 2011,
including Erratum, dated December 2011:
(1) Although the European Aviation Safety Agency (EASA) MCAI
allows the inspection of the NLG washer to be done by a pilot-owner,
the U.S. regulatory system requires all actions of this AD to be
done by a certified mechanic.
[[Page 36127]]
(2) Within 5 flight cycles (FC) after July 23, 2012 (the
effective date of this AD), inspect the installed NLG to determine
if it is one of the affected P/Ns and S/Ns as listed in paragraph
(c) of this AD.
(i) If FC data is not available, the use of a one-to-one FC to
flight hour conversion must be applied (example: 5 FC equal 5 hours
time-in-service (TIS)).
(ii) For the purpose of this AD, when an NLG P/N reference is
followed by -X or -XY, the X or XY can be any numerical digit, and
when an NLG S/N reference is EURXXX, the XXX can be any numerical
digit.
(3) If during the inspection required in paragraph (f)(2) of
this AD, you determine the NLG installed is one of the affected P/Ns
and S/Ns listed in paragraph (c) of the AD, inspect for free
rotation the washer of the NLG. Repetitively thereafter inspect the
washer of the NLG for free rotation before every flight until the
replacement and landing gear marking required in paragraphs
(f)(4)(i) and (f)(4)(ii) or paragraphs (f)(5)(i) and (f)(5)(ii) of
this AD are done.
(4) If, during any inspection required by paragraph (f)(3) of
this AD, the washer of the NLG rotates freely, before further
flight, do the following actions:
(i) Replace the bolt attaching the actuator hinge axle of the
NLG with a serviceable bolt P/N 5101301111.
(ii) Mark the landing gear with a green varnish line.
(5) For the NLG P/Ns and S/Ns as listed in paragraph (c) of this
AD, within 10 months after July 23, 2012 (the effective date of this
AD), unless already done following a discrepancy identified during
any inspection as required by paragraph (f)(3) of this AD, do the
following actions:
(i) Replace the bolt attaching the actuator hinge axle of the
NLG with a serviceable bolt P/N 5101301111 and;
(ii) Mark the landing gear with a green varnish line.
(6) Replacing of the bolt attaching the actuator hinge axle of
the NLG with a serviceable bolt P/N 5101301111 and marking the
landing gear with a green varnish line terminates the repetitive
inspections required by paragraph (f)(3) of this AD.
(7) After July 23, 2012 (the effective date of this AD), do not
install an NLG with P/N and S/N as listed in paragraph (c) of this
AD, unless the bolt attaching the actuator hinge axle of the NLG has
been replaced and the NLG has been marked with a green varnish line
following the requirements of this AD.
(g) Other FAA AD Provisions
The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager,
Standards Office, FAA, has the authority to approve AMOCs for this
AD, if requested using the procedures found in 14 CFR 39.19. Send

[email protected]. Before using any approved AMOC on any
airplane to which the AMOC applies, notify your appropriate
principal inspector (PI) in the FAA Flight Standards District Office
(FSDO), or lacking a PI, your local FSDO.
(2) Airworthy Product: For any requirement in this AD to obtain
corrective actions from a manufacturer or other source, use these
actions if they are FAA-approved. Corrective actions are considered
FAA-approved if they are approved by the State of Design Authority
(or their delegated agent). You are required to assure the product
is airworthy before it is returned to service.
(3) Reporting Requirements: For any reporting requirement in
this AD, a federal agency may not conduct or sponsor, and a person
is not required to respond to, nor shall a person be subject to a
penalty for failure to comply with a collection of information
subject to the requirements of the Paperwork Reduction Act unless
that collection of information displays a current valid OMB Control
Number. The OMB Control Number for this information collection is
2120-0056. Public reporting for this collection of information is
estimated to be approximately 5 minutes per response, including the
time for reviewing instructions, completing and reviewing the
collection of information. All responses to this collection of
information are mandatory. Comments concerning the accuracy of this
burden and suggestions for reducing the burden should be directed to

Packet generated 2026-08-18 08:18 UTC.
This packet is not an airworthiness determination and not legal or maintenance advice. AircraftDirectives reproduces official records and condenses their wording for easier reading. It does not decide, certify or imply whether any aircraft, engine, appliance or part is airworthy, compliant, affected by this directive, or eligible for return to service. No inspection, approval, or determination of any kind is performed or implied by this document.
Section 1 is a reading aid, not the rule. It is our own plain-language condensation, written to help a reader find the relevant directive quickly. It is NOT a substitute for the regulation, it may omit conditions, exceptions, compliance times, alternative methods of compliance (AMOCs) and applicability limits, and it has no legal force whatsoever. Only the official text governs. Where Section 1 and Section 2 differ in any respect, Section 2 - and the official source it was retrieved from - controls absolutely.
Responsibility remains with the owner/operator. Under 14 CFR §91.403 and §91.417 the owner or operator is responsible for maintaining airworthiness and for required records; under §39.7 no person may operate a product to which an airworthiness directive applies except in accordance with that directive. Determining applicability to a specific serial number and configuration, and performing or supervising any required action, is the responsibility of the owner/operator and appropriately certificated personnel.
Accuracy and currency. Section 2 was retrieved at the time stamped above and is reproduced without edit; Federal Register material is a work of the United States Government. Directives are amended, corrected and superseded over time, and this sheet is a snapshot, not a live record - it does not update after printing. Re-check the official sources before acting on it. This packet is provided without warranty of any kind, express or implied, including fitness for a particular purpose. We do not sell parts and have no commercial interest in any action a directive may require.
