Federal Register Abstract
We are adopting a new airworthiness directive (AD) 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. This AD was prompted by reports of cracked aluminum support struts of the trimmable horizontal stabilizer (THS) caused by stress corrosion. This AD requires 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 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.

SUMMARY: We are adopting a new airworthiness directive (AD) 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. This AD was prompted by reports of cracked aluminum
support struts of the trimmable horizontal stabilizer (THS) caused by
stress corrosion. This AD requires 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 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.
DATES: This AD becomes effective April 13, 2016.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of April 13,
2016.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would apply to all Airbus Model A300
series
[[Page 12410]]
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 NPRM
published in the Federal Register on February 18, 2015 (80 FR 8571).
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 AD 2014-0121
[<a href="http://ad.easa.europa.eu/ad/2014-0121">http://ad.easa.europa.eu/ad/2014-0121</a>] 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 <a href="http://www.regulations.gov/#!documentDetail">http://www.regulations.gov/#!documentDetail</a>;D=FAA-2015-0243-0002.
Comments
We gave the public the opportunity to participate in developing
this AD. We have considered the comments received. The following
presents the comments received on the NPRM (80 FR 8571, February 18,
2015) (``the NPRM'') and the FAA's response to each comment.
Request To Remove Repetitive Inspections From the NPRM
FedEx stated that Airbus Service Bulletin A300-53-6172, dated
February 14, 2014 and Airbus Service Bulletin A310-53-2136, dated
February 14, 2014, require an application of sealant and installation
of a clamp over the affected area. FedEx stated periodic re-inspections
for cracking of the THS support strut ends would induce further damage
since it requires removal of the reinforcing clamps and sealant before
accomplishing the HFEC inspection.
We infer from the commenter's statement that FedEx requests removal
of the repetitive inspection requirement from the proposed AD. We
disagree because if operators follow established procedures, removal of
the sealant should not introduce damage to the support struts installed
on the THS. We have not changed this final rule in this regard.
Request To Remove Installation Requirement From the NPRM
FedEx and United Parcel Service (UPS) stated they disagree with the
requirement to install the clamping. Both commenters claimed that
installing reinforcing clamps will not resolve any stress mitigation
and crack progression. UPS stated that the NPRM proposed to require
repair prior to further flight, if cracking is identified. FedEx and
UPS stated that repetitive inspections provide a sufficient level of
safety on the struts and that the installation of reinforcement clamps
does not enhance the support strut installation, but adds an additional
cost without a corresponding safety benefit. FedEx and UPS requested
removal of the clamp installation requirement specified by paragraphs
(i) and (j) of the proposed AD.
We disagree to remove the requirement to install clamping from
paragraphs (i) and (j) of this AD. The clamping reduces the
circumferential stresses in the rod-ends and supports the circular
shape of the rod ends. As a result, stress corrosion of the rod is
stopped, or partially reduced, due to the lower circumferential
stresses. We have not changed this final rule in this regard.
Request To Remove Certain References From Paragraph (l) of the NPRM
UPS requested that we remove reference to paragraphs (i)(1) through
(i)(3) of the proposed AD from paragraph (l) of the proposed AD. UPS
stated the service bulletins identified in paragraphs (i)(1) through
(i)(3) of the proposed AD do not include an inspection form or
inspection requirements within the accomplishment instructions of the
service information and therefore these documents should not be
referenced in paragraph (l) of the proposed AD, which specifies
reporting inspection results.
We agree with the request because paragraph (l) of this AD only
requires the reporting of certain inspections results. Paragraph (i) of
this AD requires an installation of reinforcing clamps. We have revised
paragraph (l) of this AD to remove the reference to paragraphs (i)(1)
through (i)(3) of this AD.
We have also revised paragraph (l) of this AD by removing a
reference to paragraph (h) of this AD in order to match the reporting
requirement specified in the MCAI. Paragraph (l) of the proposed AD
refers to inspections required by both paragraphs (g) and (h) of the
proposed AD. However, reporting is only required for inspections
required by paragraph (g) of this AD.
Request To Revise Costs of Compliance
FedEx requested that we revise the Costs of Compliance paragraph of
the proposed AD to accurately reflect the cost of replacing cracked
struts. FedEx stated it agrees that struts that are determined to be
cracked should be replaced but finds that this adds an additional
financial burden to the airlines. FedEx stated there are no warranty
provisions stated in the manufacturer's service information to mitigate
the additional expense of replacing struts, nor is it accounted for in
the NPRM.
We disagree because the conditional cost of replacing the struts
was accounted for in the NPRM by using the standard part cost for non-
avionics parts of $10,000 and an estimate that any necessary follow-on
actions would take about 15 work-hours. Further, we do not control
warranty coverage for affected individuals. We have not changed this
final rule in this regard.
Request To Include Installation of Steel Struts as Terminating Action
FedEx requested that we revise the NPRM to state that the
installation of steel struts constitutes a terminating
[[Page 12411]]
action for the repetitive inspections specified by paragraph (h) of the
proposed AD. FedEx noted that Airbus may be developing a solution that
would terminate the repetitive inspections, but as of yet, Airbus has
not published any service information that would eliminate the need for
the repetitive inspections specified by paragraph (h) of the proposed
AD.
We disagree to change this final rule because terminating action is
not available at this time. When terminating action becomes available,
the FAA may consider installation of the new design struts as an
alternative method of compliance (AMOC) to this AD once the
manufacturer's design solution is released. We have not changed this
final rule in this regard.
Request To Extend the Repetitive Inspection Interval
UPS requested that we extend the repetitive inspection interval
required by paragraph (h) of the proposed AD. UPS stated that a
manufacturer's investigation identified the cracking to be the result
of inter-granular stress corrosion and that for cracking to develop,
three factors need to be present: a material flaw at the granular
level, an environmental condition for corrosion to develop, and a
tensile load to induce damage development/propagation at the material
flaw. UPS added that the area is already protected with anti-corrosion
materials. UPS stated that based on the low occurrence of cracking, the
propagation properties of cracking due to stress corrosion, and the age
of the fleet, fleet airworthiness can be maintained using all three
operational parameters--flight hours, flight cycles, and calendar time.
UPS requested that we revise the repetitive inspection interval from 24
months to 5,000 flight hours, 2,500 flight cycles, or 36 months,
whichever occurs first.
We do not agree with the request to extend the repetitive
inspection required by paragraph (h) of this AD because the UPS
proposal is not supported by analysis or data. In developing an
appropriate compliance time for the actions specified in paragraph (h)
of this AD, we considered the safety implications and normal
maintenance schedules for the timely accomplishment of the specified
actions. We have determined that the proposed interval will ensure an
acceptable level of safety and allow the actions to be done during
scheduled maintenance intervals for most affected operators. However,
affected operators may request an AMOC to request an extension of the
repetitive inspection interval under the provisions of paragraph (m)(1)
of this AD by submitting data and analysis substantiating that the
change would provide an acceptable level of safety. We have not changed
this final rule in this regard.
Request To Delay Rule Due to Pending Release of New Design of Support
Strut and Service Information
FedEx and UPS requested that the release date of the NPRM be
suspended pending Airbus's release of a newly designed support strut
that, if installed, would be terminating action for the repetitive
inspections proposed by the NPRM. FedEx stated the manufacturer is
working on service information that contains a terminating action for
the repetitive inspections proposed in the NPRM, but as of yet, has not
been published. UPS stated that suspending the release of the NPRM
would prevent extra work for the FAA and operators.
We disagree with delaying issuance of this final rule until new
service information or a new design becomes available. We consider that
to delay this AD action would be inappropriate, in light of the
identified unsafe condition. When new service information or a new
design becomes available, we may consider additional rulemaking. We may
also consider new service information and/or installation of the new
design struts as an AMOC to this AD. Operators may apply for an AMOC in
accordance with the provisions of paragraph (m)(1) of this AD. We have
not changed this final rule in this regard.
Conclusion
We reviewed the relevant data, considered the comments received,
and determined that air safety and the public interest require adopting
this AD as proposed except for minor editorial changes. We have
determined that these minor changes:
<bullet> Are consistent with the intent that was proposed in the
NPRM for correcting the unsafe condition; and
<bullet> Do not add any additional burden upon the public than was
already proposed in the NPRM.
Related Service Information Under 1 CFR Part 51
Airbus has issued the following service information.
<bullet> Airbus Service Bulletin A300-53-0394, dated February 14,
2014. This service information describes procedures for reinforcing the

<bullet> 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 because the
interested parties have access to it through their normal course of
business or by the means identified in the ADDRESSES section.
Costs of Compliance
We estimate that this AD affects 174 airplanes of U.S. registry.
We also estimate that it will take about 5 work-hours per product
to comply with the basic requirements of this AD, and 1 work-hour per
product for reporting. The average labor rate is $85 per work-hour.
Required parts will cost about $2,100 per product. Based on these
figures, we estimate the cost of this AD on U.S. operators to be
$454,140, or $2,610 per product.
In addition, we estimate that any necessary follow-on actions will
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.
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
[[Page 12412]]
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 AD will not have federalism implications
under Executive Order 13132. This AD will 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 that this AD:
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.

(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 of each support strut installed on the 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 part number (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.

airplanes in pre-modification 06101 configuration on which any
aluminum support strut(s) having P/N R21449, P/N R21449D, P/N
R21449G, or P/N R21449H is found: Within the applicable compliance
times specified in paragraph (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
