Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued AD No. 2011– 0235–E, dated December 13, 2011 (referred to after this as ‘‘the MCAI’’), 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) PO 00000 Frm 00008 Fmt 4702 Sfmt 4702 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 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. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information DAHER–SOCATA has issued DAHER–SOCATA TBM Aircraft Mandatory Service Bulletin SB 70–194– 32, Amendment 2, dated November 2011; and Erratum to DAHER–SOCATA TBM Aircraft Mandatory Service Bulletin SB 70–194–32, Amendment 2, dated December 2011. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. FAA’s Determination and Requirements of the Proposed AD This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with this State of Design Authority, they have notified us of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. E:\FR\FM\09MRP1.SGM 09MRP1 Federal Register / Vol. 77, No. 47 / Friday, March 9, 2012 / Proposed Rules Costs of Compliance We estimate that this proposed 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 proposed 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 proposed AD on U.S. operators to be $53,760, or $120 per product. According to the manufacturer, some of the costs of this proposed 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. 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. sroberts on DSK5SPTVN1PROD with PROPOSALS Regulatory Findings We 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) 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 16:08 Mar 08, 2012 Jkt 226001 List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. Authority for This Rulemaking VerDate Mar<15>2010 (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. § 39.13 [Amended] 2. The FAA amends § 39.13 by adding the following new AD: SOCATA: Docket No. FAA–2012–0250; Directorate Identifier 2011–CE–043–AD. (a) Comments Due Date We must receive comments by April 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 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 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 PO 00000 Frm 00009 Fmt 4702 Sfmt 4702 14315 Instructions of DAHER–SOCATA TBM Aircraft Mandatory Service Bulletin SB 70– 194–32, Amendment 2, dated November 2011; and Erratum to DAHER–SOCATA TBM Aircraft Mandatory Service Bulletin SB 70– 194–32, Amendment 2, dated December 2011: (1) Although the 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. (2) Within 5 flight cycles (FC) after 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 required in paragraph (4)(i) or (5) of this AD is 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 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 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, E:\FR\FM\09MRP1.SGM 09MRP1 14316 Federal Register / Vol. 77, No. 47 / Friday, March 9, 2012 / Proposed Rules FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.

(Type Certificate Previously Held by The New Piper Aircraft Inc.) Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to supersede an existing airworthiness directive (AD) that applies to certain Piper Aircraft, Inc. (type certificate previously held by The New Piper Aircraft Inc.) Models PA–31T and PA–31T1 airplanes. The existing AD currently requires correcting a model identification error on the aircraft data plate. Since we issued that AD, we have become aware that some owner/operators of the affected airplanes modified the aircraft data plate in error because of confusion in the serial number applicability. Because of the confusion, the manufacturer has issued new service information to clarify affected airplane serial numbers. This proposed AD would require determining the airplane model based on the serial number and modifying the aircraft data plate to properly identify the airplane model. This proposed AD would also require doing a detailed search for all applicable airworthiness related documents that apply to any airplane that has an incorrectly marked data plate and take necessary corrective actions based on the search findings. We are proposing this AD to correct the unsafe condition on these products. DATES: We must receive comments on this proposed AD by April 23, 2012.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued AD 
No. 2011-0235-E, dated December 13, 2011 (referred to after this as 
``the MCAI''), 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 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.

You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    DAHER-SOCATA has issued DAHER-SOCATA TBM Aircraft Mandatory Service 
Bulletin SB 70-194-32, Amendment 2, dated November 2011; and Erratum to 
DAHER-SOCATA TBM Aircraft Mandatory Service Bulletin SB 70-194-32, 
Amendment 2, dated December 2011. The actions described in this service 
information are intended to correct the unsafe condition identified in 
the MCAI.

FAA's Determination and Requirements of the Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with this State of Design Authority, they 
have notified us of the unsafe condition described in the MCAI and 
service information referenced above. We are proposing this AD because 
we evaluated all information and determined the unsafe condition exists 
and is likely to exist or develop on other products of the same type 
design.

    We estimate that this proposed 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 proposed 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 proposed AD on 
U.S. operators to be $53,760, or $120 per product.
    According to the manufacturer, some of the costs of this proposed 
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 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) 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.

reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

    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]

    2. The FAA amends Sec.  39.13 by adding the following new AD:

SOCATA: Docket No. FAA-2012-0250; Directorate Identifier 2011-CE-
043-AD.

(a) Comments Due Date

    We must receive comments by April 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 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 
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; and 
Erratum to DAHER-SOCATA TBM Aircraft Mandatory Service Bulletin SB 
70-194-32, Amendment 2, dated December 2011:
    (1) Although the 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.
    (2) Within 5 flight cycles (FC) after 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 
required in paragraph (4)(i) or (5) of this AD is 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 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 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,
