Section 229.38 * * * * * Liability * I. 229.38(i) Presumption of Alteration 1. This paragraph establishes an evidentiary presumption of alteration of a check when the original check has been converted to an image and only an electronic check or a substitute check is available for inspection. This provision does not alter the transfer and presentment warranties under the UCC that allocate liability among the parties to a check transaction with respect to an altered or forged item. The UCC or other applicable check law continues to apply with respect to other rights, duties, and obligations related to altered or forged checks. 2. The presumption of alteration applies when the original check is unavailable for review by the banks in context of the dispute. If the original check is produced, through discovery or other means, and is made available for examination by all the parties, the presumption no longer applies. There is no presumption of alteration as between two banks that exchange an original check. By order of the Board of Governors of the Federal Reserve System, May 26, 2017. Ann E. Misback, Secretary of the Board.

Discussion On July 12, 2015, we issued AD 2015– 15–10, Amendment 39–18219 (80 FR 43928, July 24, 2015) (‘‘AD 2015–15– 10’’), for all Airbus Model A318, A319, A320, and A321 series airplanes. AD 2015–15–10 was prompted by reports of wear of the THSA. AD 2015–15–10 requires repetitive inspections of the THSA for damage, and replacement if necessary; and replacement of the THSA after reaching a certain life limit. We issued AD 2015–15–10 to detect and correct wear on the THSA, which would reduce the remaining life of the THSA, possibly resulting in premature failure and consequent reduced controllability of the airplane. Since we issued AD 2015–15–10, an additional life limit for the THSA has been established, based on flight cycles. In addition, the THSA manufacturer has issued service information which, when accomplished, increases the life limit of the THSA. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2016–0184, dated September 13, 2016 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for all Airbus Model A318 and A319 series airplanes; Model A320–211, –212, –214, –231, –232, and –233 airplanes; and Model E:\FR\FM\02JNP1.SGM 02JNP1 25543 Federal Register / Vol. 82, No. 105 / Friday, June 2, 2017 / Proposed Rules A321–111, –112, –131, –211, –212, –213, –231, and –232 airplanes. The MCAI states: In the frame of the A320 Extended Service Goal (ESG) project and the study on the Trimmable Horizontal Stabilizer Actuator (THSA), a sampling programme of in-service units was performed and several cases of wear at different THSA levels were reported. This condition, if not detected and corrected, would reduce the remaining life of the THSA, possibly resulting in premature failure and consequent reduced control of the aeroplane. Prompted by these findings, Airbus issued Service Bulletin (SB) A320–27–1227 to provide THSA inspection instructions. Consequently, EASA issued AD 2014–0011 (later revised) [which corresponds to AD 2015–15–10] to require repetitive inspections of the THSA [and related investigative and corrective actions] and to introduce a life limit for the THSA, based on flight hours (FH). Since EASA AD 2014–0011R1 was issued, an additional life limitation has been established, based on flight cycles (FC). Furthermore, United Technologies Corporation Aerospace Systems (UTAS), the THSA manufacturer, issued an SB which, after accomplishment on THSA, increases the life limit of the THSA. For the reasons described above, this [EASA] AD retains the requirements of EASA AD 2014–0011R1, which is superseded, and introduces an additional FC life limit for the affected THSA. This [EASA] AD also provides a revised life limit for the THSA after UTAS SB accomplishment on that THSA. describes procedures for repetitive special detailed inspections for wear of the THSA, and related investigative and corrective actions. 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. The required action is repetitive special detailed inspections of the THSA. The optional terminating action is overhaul of the THSA. The related investigative action is a spectrometric analysis of the oil drained from the THSA gearbox. The corrective action is replacement of a THSA with a serviceable THSA. The compliance time for the related investigative and corrective actions varies depending on the findings, and ranges from before further flight to 4 months or between 1,000 and 1,250 flight hours since the first THSA oil drain. You may examine the MCAI in the AD docket on the Internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2017– 0498. FAA’s Determination and Requirements of This 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 the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of these same type designs. Costs of Compliance Related Service Information Under 1 CFR Part 51 Airbus has issued Service Bulletin A320–27–1227, Revision 03, dated April 29, 2016. This service information We estimate that this proposed AD affects 1,182 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Action Labor cost Inspections .................... 6 work-hours × $85 per hour = $510 per inspection cycle. We have received no definitive data that would enable us to provide cost estimates for the spectrometric analysis of the oil drained from the THSA Parts cost Cost per product $0 $510 per inspection cycle. gearbox. We estimate the following costs to do any necessary replacements or overhauls that would be required based on the results of the proposed Cost on U.S. operators $602,820 per inspection cycle. inspection. We have no way of determining the number of aircraft that might need these replacements or overhauls: ON-CONDITION COSTS Replacement of THSA (retained from AD 2015–15– 10). Overhaul of THSA (new proposed action) ................... nlaroche on DSK30NT082PROD with PROPOSALS Labor cost 11 work-hours × $85 per hour = $935 ......................... $240,000 $240,935 66 work-hours × $85 per hour = $5,610 ...................... 115,000 120,610 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 VerDate Sep<11>2014 13:14 Jun 01, 2017 Jkt 241001 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. PO 00000 Frm 00005 Fmt 4702 Sfmt 4702 Parts cost Cost per product 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: E:\FR\FM\02JNP1.SGM 02JNP1 25544 Federal Register / Vol. 82, No. 105 / Friday, June 2, 2017 / Proposed Rules 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.

Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2015-15-
10, for all Airbus Model A318, A319, A320, and A321 series airplanes.
AD 2015-15-10 currently requires repetitive inspections of the
trimmable horizontal stabilizer actuator (THSA) for damage, and
replacement if necessary; and replacement of the THSA after reaching a
certain life limit. Since we issued AD 2015-15-10, an additional life
limit for the THSA has been established, based on flight cycles. In
addition, the THSA manufacturer has issued service information which,
when accomplished, increases the life limit of the THSA. This proposed
AD would require repetitive detailed inspections of certain THSAs, and

Discussion

On July 12, 2015, we issued AD 2015-15-10, Amendment 39-18219 (80
FR 43928, July 24, 2015) (``AD 2015-15-10''), for all Airbus Model
A318, A319, A320, and A321 series airplanes. AD 2015-15-10 was prompted
by reports of wear of the THSA. AD 2015-15-10 requires repetitive
inspections of the THSA for damage, and replacement if necessary; and
replacement of the THSA after reaching a certain life limit. We issued
AD 2015-15-10 to detect and correct wear on the THSA, which would
reduce the remaining life of the THSA, possibly resulting in premature
failure and consequent reduced controllability of the airplane.
Since we issued AD 2015-15-10, an additional life limit for the
THSA has been established, based on flight cycles. In addition, the
THSA manufacturer has issued service information which, when
accomplished, increases the life limit of the THSA.
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Union, has issued EASA
Airworthiness Directive 2016-0184, dated September 13, 2016 (referred
to after this as the Mandatory Continuing Airworthiness Information, or
``the MCAI''), to correct an unsafe condition for all Airbus Model A318
and A319 series airplanes; Model A320-211, -212, -214, -231, -232, and
-233 airplanes; and Model

[[Page 25543]]

A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes. The
MCAI states:

In the frame of the A320 Extended Service Goal (ESG) project and
the study on the Trimmable Horizontal Stabilizer Actuator (THSA), a
sampling programme of in-service units was performed and several
cases of wear at different THSA levels were reported.
This condition, if not detected and corrected, would reduce the
remaining life of the THSA, possibly resulting in premature failure
and consequent reduced control of the aeroplane.
Prompted by these findings, Airbus issued Service Bulletin (SB)
A320-27-1227 to provide THSA inspection instructions. Consequently,
EASA issued AD 2014-0011 (later revised) [which corresponds to AD
2015-15-10] to require repetitive inspections of the THSA [and
related investigative and corrective actions] and to introduce a
life limit for the THSA, based on flight hours (FH).
Since EASA AD 2014-0011R1 was issued, an additional life
limitation has been established, based on flight cycles (FC).
Furthermore, United Technologies Corporation Aerospace Systems
(UTAS), the THSA manufacturer, issued an SB which, after
accomplishment on THSA, increases the life limit of the THSA.
For the reasons described above, this [EASA] AD retains the
requirements of EASA AD 2014-0011R1, which is superseded, and
introduces an additional FC life limit for the affected THSA. This
[EASA] AD also provides a revised life limit for the THSA after UTAS
SB accomplishment on that THSA.

The required action is repetitive special detailed inspections of
the THSA. The optional terminating action is overhaul of the THSA. The
related investigative action is a spectrometric analysis of the oil
drained from the THSA gearbox. The corrective action is replacement of
a THSA with a serviceable THSA.
The compliance time for the related investigative and corrective
actions varies depending on the findings, and ranges from before
further flight to 4 months or between 1,000 and 1,250 flight hours
since the first THSA oil drain.
You may examine the MCAI in the AD docket on the Internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2017-
0498.

Related Service Information Under 1 CFR Part 51

Airbus has issued Service Bulletin A320-27-1227, Revision 03, dated
April 29, 2016. This service information describes procedures for
repetitive special detailed inspections for wear of the THSA, and
related investigative and corrective actions.
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.

FAA's Determination and Requirements of This 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 the State of Design Authority, we have
been notified of the unsafe condition described in the MCAI and service
information referenced above. We are proposing this AD because we
evaluated all pertinent information and determined an unsafe condition
exists and is likely to exist or develop on other products of these
same type designs.

Costs of Compliance

We estimate that this proposed AD affects 1,182 airplanes of U.S.
registry.
We estimate the following costs to comply with this proposed AD:

Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost on U.S.
Action Labor cost Parts cost Cost per product operators

inspection cycle.
----------------------------------------------------------------------------------------------------------------

We have received no definitive data that would enable us to provide
cost estimates for the spectrometric analysis of the oil drained from
the THSA gearbox. We estimate the following costs to do any necessary
replacements or overhauls that would be required based on the results
of the proposed inspection. We have no way of determining the number of
aircraft that might need these replacements or overhauls:

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:

[[Page 25544]]

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.

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

(k) Replacement THSA: No Terminating Action

Replacement of a THSA on an airplane, as required by paragraph
(i) or (j) of this AD, does not constitute terminating action for
the repetitive inspections required by paragraph (h) of this AD for
that airplane, unless the THSA is overhauled as specified in the
Accomplishment Instructions of UTAS Service Bulletin 47145-27-19
(i.e., post-service bulletin).

(l) Optional Terminating Action: Overhaul of THSA

Accomplishment of a modification of an airplane by installing a
THSA that has been overhauled as specified in UTAS Service Bulletin
47145-27-19 constitutes terminating action for the repetitive
inspections required by paragraph (h) of this AD, provided that,
following modification, no THSA is reinstalled on the airplane
unless it has been overhauled as specified in UTAS Service Bulletin
47145-27-19.
