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.
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.

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 removing Airworthiness Directive (AD)
98-16-03, Amendment 39-10677 (63 FR 40359; July 29, 1998), and adding
the following new AD:
