14 CFR Part 39

[Docket No. FAA-2018-0326; Product Identifier 2018-CE-006-AD]
RIN 2120-AA64


Airworthiness Directives; SOCATA Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 98-16-03 
for SOCATA Models TB 9 and TB 10 airplanes. This proposed AD results 
from 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 fatigue cracking of the wing front attachments on the wing 
and fuselage sides. We are issuing this proposed AD to require actions 
to address the unsafe condition on these products.

DATES: We must receive comments on this proposed AD by June 25, 2018.

ADDRESSES: You may send comments by any of the following methods:

Discussion

    We issued AD 98-16-03, Amendment 39-10677 (63 FR 40359; July 29, 
1998). That AD required actions intended to address an unsafe condition 
on SOCATA Models TB 9 and TB 10 airplanes and was based on mandatory 
continuing airworthiness information (MCAI) originated by an aviation 
authority of another country.
    Since we issued AD 98-16-03, SOCATA developed improved repair 
procedures and increased the applicability to include Model TB 200 
airplanes.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
AD No. 2018-0030, dated January 31, 2018 (referred to after this as 
``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

    During a scheduled maintenance inspection, cracks were found on 
the wing front attachments of a TB 10 aeroplane.
    This condition, if not detected and corrected, could affect the 
structural integrity of the aeroplane.
    Prompted by these findings, SOCATA issued SB 10-081-57 to 
provide inspection and modification instructions, and DGAC France 
issued AD 94-264(A), later revised, to require repetitive 
inspections of wing front attachments of TB 9 and TB 10 aeroplanes 
(all MSN up to 822 inclusive, with some excluded). That [DGAC 
France] AD also required installation of reinforcement kits, applied 
as repair (if cracks were found) or as modification (if no cracks 
were found), of the wing front attachments, on both wing and 
fuselage sides, and repetitive replacement of those reinforcements 
afterwards.
    Since DGAC France AD 94-264(A) R1 was issued, cracks have been 
found on wing front attachments, on the wing side, on TB10 
aeroplanes to which the AD did not apply, i.e. which were not 
subject to repetitive inspections as required by that [DGAC France] 
AD. Consequently, SOCATA revised SB 10-081-57 (now at revision (rev) 
3), extending the Applicability to all TB 10 aeroplanes, as well as 
to TB 200 aeroplanes, and improving the repair solution of the wing 
front attachment on wing side.
    For the reason described above, this [EASA] AD retains the 
requirements of DGAC France AD 94-264(A) R1, which is superseded, 
expands the Applicability to all MSN for TB 9 and TB 10 aeroplanes 
and includes TB 200 aeroplanes, and requires an improved repair 
solution of the wing front attachment on wing side.

    You may examine the MCAI on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2018-
0326.

Related Service Information Under 1 CFR Part 51

    SOCATA has issued Daher Service Bulletin SB 10-081, Revision 3, 
dated December 2017. The service bulletin describes procedures for 
inspecting the front attachments and installing modification kits. This 
service information 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 of this NPRM.

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.

Costs of Compliance

    We estimate that this proposed AD will affect 126 products of U.S. 
registry. We also estimate that it would take about 3 work-hours per 
product to comply with the inspection requirements of this proposed AD. 
We also estimate that it would take about 25 work-hours per product to 
comply with the replacement/modification (wing and fuselage sides) 
requirements of this proposed AD. The average labor rate is $85 per 
work-hour. Required parts would cost about $3,000 per product.
    Based on these figures, we estimate the cost of the proposed AD on 
U.S. operators to be $677,880, or $5,380 per product.
    In addition, we estimate that any necessary follow-on actions to 
replace the wing attachment on the wing side, resulting from the 
repetitive inspections, would take about 9 work-hours and require parts 
costing $3,000, for a cost of $3,765 per product. We have no way of 
determining the number of products that may need these actions.

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.

[[Page 21201]]

    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to small airplanes, gliders, 
balloons, airships, domestic business jet transport airplanes, and 
associated appliances to the Director of the Policy and Innovation 
Division.

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.

country to identify and correct an unsafe condition on an aviation 
product. The MCAI describes the unsafe condition as fatigue cracking 
of the wing front attachments on the wing and fuselage sides. We are 
issuing this AD to prevent fatigue cracking of the wing front 
attachments, which could lead to structural failure of the airplane 
and loss of control.

(f) Compliance

    Unless already done, do the following actions listed in 
paragraphs (g) through (j) of this AD. The compliance times of this 
AD are presented in landings instead of hours time-in-service (TIS). 
If the number of landings is unknown, multiply the number of hours 
TIS by 1.5. For the purposes of this AD, ``XX'' can be any numerical 
value.

(g) Actions for Airplanes NOT EQUIPPED With Modification Kit 
OPT109110XX

    (1) Within the compliance time specified in table 1 to paragraph 
(g)(1) of this AD, do an initial inspection of the wing front

    (4) Before or upon accumulating 12,000 landings after the 
reinforcement modification required in paragraph (i)(2) or (3) of 
this AD, replace the reinforced front attachment on the fuselage 
side following the Description of Accomplishment Instructions in 
SOCATA Daher Service Bulletin SB 10-081, Revision 3, December 2017.

(j) Replacement of the Reinforced Front Attachment

    Replacement of the reinforced front attachment on the wing side 
and/or replacement of the reinforced front attachment on the 
fuselage side, does not terminate the inspections required in 
paragraphs (h)(1) and (i)(1) of this AD. After replacement, the 
initial and repetitive inspection cycle starts over.

(k) Credit for Previous Actions

    This AD allows credit for the initial inspection required in 
paragraphs (g)(1) and (i)(1) of this AD and any replacement that may 
have been required based on the initial inspection, if done before 
the effective date of this AD, following Socata Service Bulletin No. 
SB 10-081-57, Revison 1, dated August 1996 or Revision 2, dated 
January 2017. Any inspections or replacements done after the 
effective date must be done following SOCATA Daher Service Bulletin
