prompted by reports of cracked
aluminum support struts of the
trimmable horizontal stabilizer (THS)
caused by stress corrosion. This
proposed AD would require inspections
to identify the part number of each

cracking of the THS support strut ends,
installation of reinforcing clamps on
strut ends, and replacement of support
struts, if necessary. We are proposing
this AD to detect and correct cracked
THS support struts, which could lead to
the rupture of all four support struts
making the remaining structure unable
to carry limit loads, which could result
in loss of the THS and reduced control
of the airplane.

Discussion
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Union, has issued EASA Airworthiness
Directive 2014–0164, dated July 11,
2014 (referred to after this as the
Mandatory Continuing Airworthiness
Information, or ‘‘the MCAI’’), to correct
an unsafe condition for all Airbus
Model A300 series airplanes; Model
A300 B4–600, B4–600R, and F4–600R
series airplanes, and A300 C4–605R
Variant F airplanes (collectively called
Model A300–600 series airplanes); and
Model A310 series airplanes. The MCAI
states:
During scheduled maintenance, several
Trimmable Horizontal Stabilizer (THS)
support struts were found cracked at the strut
ends. The THS is supported and articulated
at frame (FR) 91 in the tail cone. Lateral
movement is prevented by four diagonal
support struts.
PO 00000
Frm 00012
Fmt 4702
Sfmt 4702
Investigations revealed that the cracks were
caused by stress corrosion and propagated
from the inside to the outside of the strut.
This condition, if not detected and
corrected, could lead to the rupture of all
four THS support struts at FR91, which
would make the remaining structure unable
to carry limit loads, potentially resulting in
loss of the Horizontal Tail Plane.
To address this unsafe condition, EASA
issued [EASA] AD 2014–0121 [https://
ad.easa.europa.eu/ad/2014-0121] to require
repetitive High Frequency Eddy Current
(HFEC) inspections of the THS support strut
ends, installation of reinforcing clamps on
strut ends and, depending on findings,
replacement of damaged support struts.
Installation of reinforcing clamps on strut
ends is considered a temporary solution
pending introduction of a re-designed
support strut.
Since that [EASA] AD was issued, it was
discovered that the [EASA] AD appeared to
also require HFEC inspections of steel struts,
which are not prone to cracking. The unsafe
condition exists only on support struts made
of aluminum, which were introduced
through Airbus modification (mod) 06101,
but may also have been installed in service
as replacement parts on aeroplanes in premod 06101 configuration.
For the reason described above, this
[EASA] AD retains the requirements of EASA
AD 2014–0121, which is superseded, and
clarifies the need for an initial identification
of the support struts installed on aeroplanes
in pre-mod 06101 configuration. The related
Airbus Service Bulletins (SB) remain
unchanged.
You may examine the MCAI in the
AD docket on the Internet at https://

and locating Docket No. FAA–2015–
0243.

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.
Differences Between This Proposed AD
and the MCAI or Service Information
Unlike the procedures described in
Airbus Service Bulletin A300–53–0395;
Airbus Service Bulletin A300–53–6174;
and Airbus Service Bulletin A310–53–
2137; each dated February 14, 2014; this
proposed AD would not permit further
flight if cracks are detected in the
aluminum support strut ends of the
trimmable horizontal stabilizer at frame
91. We have determined that, because of
the safety implications and
consequences associated with that
cracking, any cracked aluminum
support strut ends of the trimmable
horizontal stabilizer must be repaired or
modified before further flight. This
difference has been coordinated with
EASA and Airbus.
Costs of Compliance
We estimate that this proposed AD
affects 174 airplanes of U.S. registry.
We also estimate that it would take
about 5 work-hours per product to
comply with the basic requirements of
VerDate Sep<11>2014
17:51 Feb 17, 2015
Jkt 235001
this proposed AD. The average labor
rate is $85 per work-hour. Required
parts would cost about $2,100 per
product. Based on these figures, we
estimate the cost of this proposed AD on
U.S. operators to be $439,350, or $2,525
per product.
In addition, we estimate that any
necessary follow-on actions would take
about 15 work-hours and require parts
costing $10,000, for a cost of $11,275
per product. We have no way of
determining the number of aircraft that
might need these actions.
Paperwork Reduction Act
A federal agency may not conduct or
sponsor, and a person is not required to
respond to, nor shall a person be subject
to 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 control
number for the collection of information
required by this proposed AD is 2120–
0056. The paperwork cost associated
with this proposed AD has been
detailed in the Costs of Compliance
section of this document and includes
time for reviewing instructions, as well
as completing and reviewing the
collection of information. Therefore, all
reporting associated with this proposed
AD is mandatory. Comments concerning
the accuracy of this burden and
suggestions for reducing the burden
should be directed to the FAA at 800
Independence Ave. SW., Washington,
DC 20591, ATTN: Information
Collection Clearance Officer, AES–200.
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.

(g) Inspection for Part Number
For airplanes in pre-modification 06101
configuration: Within 12 months after the
effective date of this AD, do an inspection to
identify the part number (P/N) of each
support strut installed on the trimmable
horizontal stabilizer (THS) at frame (FR) 91,
in accordance with the Accomplishment
Instructions of the applicable service bulletin
identified in paragraphs (g)(1) through (g)(3)
of this AD. A review of airplane maintenance
records is acceptable in lieu of this
inspection, provided those records can be
relied upon for that purpose and the part
number can be positively identified from that
review. If no aluminum strut(s) having P/N
R21449, R21449D, R21449G, or R21449H is
found during any inspection required by this
paragraph no further action is required by
this AD for that horizontal stabilizer, except
for paragraph (l) of this AD.

AGENCY:
We propose to adopt a new
airworthiness directive (AD) for all
Airbus Model A310–203 airplanes. This
proposed AD is intended to complete
certain mandated programs intended to
support the airplane reaching its limit of
validity (LOV) of the engineering data
that support the established structural
maintenance program. This proposed
AD was prompted by reports that side
link clevis bolts of the front engine
mount do not meet the Design Service
Goal (DSG) requirements on airplanes
equipped with General Electric
Company CF6–80A3 engines. This
proposed AD would require repetitive
replacement of all side link clevis
engine mount bolts. We are proposing
this AD to prevent failure of the front
engine mount, and consequent possible
departure of the engine.

Discussion
As described in FAA Advisory
Circular 120 104 (https://www.faa.gov/
documentLibrary/media/Advisory_
Circular/120-104.pdf), several programs
have been developed to support
initiatives that will ensure the
continued airworthiness of aging
airplane structure. The last element of
those initiatives is the requirement to
establish a LOV of the engineering data
that support the structural maintenance
program under 14 CFR 26.21. This
proposed AD is the result of an
assessment of the previously established
programs by Airbus during the process
of establishing the LOV for Airbus
Model A310–203 airplanes. The actions
specified in this proposed AD are
necessary to complete certain programs
to ensure the continued airworthiness of
aging airplane structure and to support
an airplane reaching its LOV.
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Union, has issued EASA Airworthiness
Directive 2014–0191, dated August 29,
2014 (referred to after this as the
Mandatory Continuing Airworthiness
Information, or ‘‘the MCAI’’), to correct
an unsafe condition for all Airbus
Model A310–203 airplanes. The MCAI
states:
During fatigue analysis performed in the
scope of the Extended Service Goal, taking
into account the certification loads and the
new lift-off loads, Airbus determined that
side link clevis engine mount bolts do not
meet the Design Service Goal (DSG)
requirements on aeroplanes equipped with
CF6–80A3 engines.
This condition, if not corrected, could lead
to failure of the front engine mount, possibly
resulting in-flight separation of the engine
from the aeroplane.
To address this potential unsafe condition,
Airbus issued Service Bulletin (SB) A310–
71–2038 to introduce a life limit on the side
link clevis engine mount bolts.
For the reason described above, this
[EASA] AD requires implementation of the
new life limit and replacement of all side
link clevis engine mount bolts that have
exceeded the new limit.

Airbus Model A300 series airplanes; Model A300 B4-600, B4-600R, and F4-
600R series airplanes, and A300 C4-605R Variant F airplanes
(collectively called Model A300-600 series airplanes); and Model A310
series airplanes. This proposed AD was prompted by reports of cracked
aluminum support struts of the trimmable horizontal stabilizer (THS)
caused by stress corrosion. This proposed AD would require inspections
to identify the part number of each support strut, repetitive
inspections for cracking of the THS support strut ends, installation of
reinforcing clamps on strut ends, and replacement of support struts, if
necessary. We are proposing this AD to detect and correct cracked THS
support struts, which could lead to the rupture of all four support
struts making the remaining structure unable to carry limit loads,
which could result in loss of the THS and reduced control of the
airplane.

Discussion
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Union, has issued EASA
Airworthiness Directive 2014-0164, dated July 11, 2014 (referred to
after this as the Mandatory Continuing Airworthiness Information, or
``the MCAI''), to correct an unsafe condition for all Airbus Model A300
series airplanes; Model A300 B4-600, B4-600R, and F4-600R series
airplanes, and A300 C4-605R Variant F airplanes (collectively called
Model A300-600 series airplanes); and Model A310 series airplanes. The
MCAI states:
During scheduled maintenance, several Trimmable Horizontal
Stabilizer (THS) support struts were found cracked at the strut
ends. The THS is supported and articulated at frame (FR) 91 in the
tail cone. Lateral movement is prevented by four diagonal support
struts.
Investigations revealed that the cracks were caused by stress
corrosion and propagated from the inside to the outside of the
strut.
This condition, if not detected and corrected, could lead to the
rupture of all four THS support struts at FR91, which would make the
remaining structure unable to carry limit loads, potentially
resulting in loss of the Horizontal Tail Plane.
To address this unsafe condition, EASA issued [EASA] AD 2014-
0121 [https://ad.easa.europa.eu/ad/2014-0121] to require repetitive
High Frequency Eddy Current (HFEC) inspections of the THS support
strut ends, installation of reinforcing clamps on strut ends and,
depending on findings, replacement of damaged support struts.
Installation of reinforcing clamps on strut ends is considered a
temporary solution pending introduction of a re-designed support
strut.
Since that [EASA] AD was issued, it was discovered that the
[EASA] AD appeared to also require HFEC inspections of steel struts,
which are not prone to cracking. The unsafe condition exists only on
support struts made of aluminum, which were introduced through
Airbus modification (mod) 06101, but may also have been installed in
service as replacement parts on aeroplanes in pre-mod 06101
configuration.
For the reason described above, this [EASA] AD retains the
requirements of EASA AD 2014-0121, which is superseded, and
clarifies the need for an initial identification of the support
struts installed on aeroplanes in pre-mod 06101 configuration. The
related Airbus Service Bulletins (SB) remain unchanged.
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-2015-
0243.
Relevant Service Information Under 1 CFR Part 51
Airbus has issued the following service information. The actions
described in this service information are intended to correct the
unsafe condition identified in the MCAI.
Airbus Service Bulletin A300-53-0394, dated February 14,
2014. This service information describes procedures for reinforcing the
support struts of the THS at frame 91 in the fuselage tail section of
Airbus Model A300 series airplanes.
Airbus Service Bulletin A300-53-0395, dated February 14,
2014. This service information describes procedures for inspecting for
cracking of the support struts of the THS at frame 91 in the fuselage
tail section of Airbus Model A300 series airplanes.
Airbus Service Bulletin A300-53-6172, dated February 14,
2014. This service information describes procedures for reinforcing the
support struts of the THS at frame 91 in the fuselage tail section of
Airbus Model A300-600 series airplanes.
[[Page 8573]]
Airbus Service Bulletin A300-53-6174, dated February 14,
2014. This service information describes procedures for inspecting for
cracking of the support struts of the THS at frame 91 in the fuselage
tail section of Airbus Model A300-600 series airplanes.
Airbus Service Bulletin A310-53-2136, dated February 14,
2014. This service information describes procedures for reinforcing the
support struts of the THS at frame 91 in the fuselage tail section of

Airbus Service Bulletin A310-53-2137, dated February 14,
2014. This service information describes procedures for inspecting for
cracking of the support struts of the THS at frame 91 in the fuselage
tail section of Airbus Model A310 series airplanes. This service
information is reasonably available; see ADDRESSES for ways to access
this service information.
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.
Differences Between This Proposed AD and the MCAI or Service
Information
Unlike the procedures described in Airbus Service Bulletin A300-53-
0395; Airbus Service Bulletin A300-53-6174; and Airbus Service Bulletin
A310-53-2137; each dated February 14, 2014; this proposed AD would not
permit further flight if cracks are detected in the aluminum support
strut ends of the trimmable horizontal stabilizer at frame 91. We have
determined that, because of the safety implications and consequences
associated with that cracking, any cracked aluminum support strut ends
of the trimmable horizontal stabilizer must be repaired or modified
before further flight. This difference has been coordinated with EASA
and Airbus.
Costs of Compliance
We estimate that this proposed AD affects 174 airplanes of U.S.
registry.
We also estimate that it would take about 5 work-hours 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 $2,100
per product. Based on these figures, we estimate the cost of this
proposed AD on U.S. operators to be $439,350, or $2,525 per product.
In addition, we estimate that any necessary follow-on actions would
take about 15 work-hours and require parts costing $10,000, for a cost
of $11,275 per product. We have no way of determining the number of
aircraft that might need these actions.
Paperwork Reduction Act
A federal agency may not conduct or sponsor, and a person is not
required to respond to, nor shall a person be subject to 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 control
number for the collection of information required by this proposed AD
is 2120-0056. The paperwork cost associated with this proposed AD has
been detailed in the Costs of Compliance section of this document and
includes time for reviewing instructions, as well as completing and
reviewing the collection of information. Therefore, all reporting
associated with this proposed AD is mandatory. Comments concerning the
accuracy of this burden and suggestions for reducing the burden should
be directed to the FAA at 800 Independence Ave. SW., Washington, DC
20591, ATTN: Information Collection Clearance Officer, AES-200.
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.

2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive (AD):
Airbus: Docket No. FAA-2015-0243; Directorate Identifier 2014-NM-
114-AD.
(a) Comments Due Date
We must receive comments by April 6, 2015.
(b) Affected ADs
None.
(c) Applicability
This AD applies to the Airbus airplanes specified in paragraphs
(c)(1) through (c)(6) of this AD, certificated in any category, all
manufacturer serial numbers.
(1) Airbus Model A300 B2-1A, B2-1C, B2K-3C, B2-203, B4-2C, B4-
103, and B4-203 airplanes.
(2) Airbus Model A300 B4-601, B4-603, B4-620, and B4-622
airplanes.

(6) Airbus Model A310-203, -204, -221, -222, -304, -322, -324,
and -325 airplanes.
(d) Subject
Air Transport Association (ATA) of America Code 53, Fuselage.
(e) Reason
This AD was prompted by reports of cracked aluminum support
struts of the trimmable horizontal stabilizer (THS) caused by stress
corrosion. We are issuing this AD to detect and correct cracked THS
support struts, which could lead to the rupture of all four support
struts making the remaining structure unable to carry limit loads,
which could result in loss of the THS and reduced control of the
airplane.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Inspection for Part Number
For airplanes in pre-modification 06101 configuration: Within 12
months after the effective date of this AD, do an inspection to
identify the part number (P/N) of each support strut installed on
the trimmable horizontal stabilizer (THS) at frame (FR) 91, in
accordance with the Accomplishment Instructions of the applicable
service bulletin identified in paragraphs (g)(1) through (g)(3) of
this AD. A review of airplane maintenance records is acceptable in
lieu of this inspection, provided those records can be relied upon
for that purpose and the part number can be positively identified
from that review. If no aluminum strut(s) having P/N R21449,
R21449D, R21449G, or R21449H is found during any inspection required
by this paragraph no further action is required by this AD for that
horizontal stabilizer, except for paragraph (l) of this AD.
(1) For Airbus Model A300 series airplanes: Airbus Service
Bulletin A300-53-0395, dated February 14, 2014.
(2) For Airbus Model A300 B4-600, B4-600R, and F4-600R series
airplanes, and A300 C4-605R Variant F airplanes (collectively called
Model A300-600 series airplanes): Airbus Service Bulletin A300-53-
6174, dated February 14, 2014.
(3) For Airbus Model A310 series airplanes: Airbus Service
Bulletin A310-53-2137, dated February 14, 2014.
(h) Repetitive High Frequency Eddy Current (HFEC) Inspections
For airplanes in post-modification 06101 configuration; and for
airplanes in pre-modification 06101 configuration on which one or
more aluminum support strut(s) having P/N R21449, P/N R21449D, P/N
R21449G, or P/N R21449H was found during the inspection by paragraph
(g) of this AD: Within the applicable compliance times specified in
paragraphs (h)(1), (h)(2), or (h)(3) of this AD, do an HFEC
inspection for cracking of the aluminum THS support strut ends at FR
91, in accordance with the Accomplishment Instructions of the
applicable service bulletin identified in paragraphs (g)(1) through
(g)(3) of this AD. Reinforcing clamps already installed on strut
ends must be removed before accomplishing the HFEC inspection and
re-installed after the inspection, in accordance with the
Accomplishment Instructions of the applicable service bulletin
specified in paragraphs (g)(1) through (g)(3) of this AD. Repeat the
inspection thereafter at intervals not to exceed 24 months.
(1) For airplanes having manufacturer serial number (MSN) 0499
through MSN 0747 inclusive (post-mod 06101): Within 12 months after
the effective date of this AD.
(2) For airplanes having MSN 0748 through MSN 0878 inclusive
(post-mod 06101): Within 18 months after the effective date of this
AD.
(3) For airplanes having MSN 0001 through MSN 0498 inclusive
(pre-mod 06101) having one or more aluminum struts: Within 24 months
after the effective date of this AD.
(i) Installation of Reinforcing Clamps
Concurrently with the initial HFEC inspection required by
paragraph (h) of this AD, identify struts having P/N R21449, P/N
R21449D, P/N R21449G, or P/N R21449H with no reinforcing clamps
previously installed, and before next flight, install reinforcing
clamps on each strut end, in accordance with the Accomplishment
Instructions of the applicable service bulletin specified in
paragraphs (i)(1) through (i)(3) of this AD.
(1) For Airbus Model A300 series airplanes: Airbus Service
Bulletin A300-53-0394, dated February 14, 2014.
(2) For Airbus Model A300 B4-600, B4-600R, and F4-600R series
airplanes, and A300 C4-605R Variant F airplanes (collectively called
Model A300-600 series airplanes): Airbus Service Bulletin A300-53-
6172, dated February 14, 2014.
(3) For Airbus Model A310 series airplanes: Airbus Service
Bulletin A310-53-2136, dated February 14, 2014.
(j) Corrective Actions
If, during any inspection required by paragraph (h) of this AD,
any cracking is found, before further flight, replace the affected
THS support strut(s) with serviceable struts and install clamps on
each strut end, in accordance with the Accomplishment Instructions
of the applicable service bulletin identified in paragraphs (g)(1)
through (g)(3) of this AD.
(k) Clarification
Installation of reinforcing clamps as required by paragraph (i)
of this AD, and the replacement of support struts and/or the
installation of clamps as required by paragraph (j) of this AD, do
not constitute terminating action for the repetitive inspections
required by paragraph (h) of this AD.
(l) Reporting
At the applicable time specified in paragraphs (l)(1) and (l)(2)
of this AD: After accomplishment of any inspection required by
paragraphs (g) and (h) of this AD, report all inspection results to
Airbus, including no findings, in accordance with the Accomplishment
Instructions of the applicable service bulletins specified in
