ACTION: Final rule.
AGENCY:
We are adopting a new
airworthiness directive (AD) for all
Airbus Model A330–200 and A330–300
series airplanes, and Model A340–200
and A340–300 series airplanes. This AD
was prompted by reports of an elevator
blocked in the down position due to two
independent failures; first, the inability
of a servo control to switch to active
mode because it was not detected by a
flight control computer; and second, an
internal hydraulic leak due to the
deterioration of an O-ring seal on a
solenoid. This AD requires, depending
on airplane configuration, modifying
three flight control primary computers
(FCPCs); modifying two flight control
secondary computers (FCSCs); revising
the airplane flight manual (AFM) to
include certain information; replacing
certain O-rings; and checking part
number and replacing certain O-ring
seals if needed. We are issuing this AD
to detect and correct O-rings with
incorrect part numbers whose
deterioration could lead to improper
sealing of solenoid valves; and to correct
FCPC and FCSC software to allow better
control of elevator positioning; both
conditions, if not corrected, could lead
to the loss of elevator control on takeoff,
and potentially reduce the
controllability of the airplane.
DATES: This AD becomes effective June
13, 2013.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would
apply to the specified products. That
NPRM was published in the Federal
Register on August 14, 2012 (77 FR
48469). That NPRM proposed to correct
an unsafe condition for the specified
products. The Mandatory Continuing
Airworthiness Information (MCAI)
states:
This [European Aviation Safety Agency
(EASA)] AD [2010–0081, dated April 27,
2010] deals with the two following points:
• Case of an elevator blocked in down
position due to two independent failures one
of which is hidden:
Each elevator is controlled by two servo
controls. In normal operation:
—one servo control in active mode controlled
by PRIM 1 (Green servo control),
—one servo control in damping mode
(Yellow or Blue servo control) monitored
by PRIM 2.
Change from active mode to damped mode
is obtained by means of a mode selector
which is controlled by two identical solenoid
valves housed on the servo control. The
sealing of each solenoid valve is ensured by
four O-ring seals.
During pre-flight control checks, the flight
crew of an A330–200 aeroplane observed that
one of the elevators was blocked in down
position, the ECAM [electronic centralized
aircraft monitor] screen displaying ‘‘F/CTL
PRIM 1 PITCH FAULT’’.
This condition was due to two
independent failures, one of which was
dormant, which occurred on one of the
elevators.
Investigations revealed that the origin of
the elevator malfunction was due to the
inability of the Yellow servo control to
switch to active mode.
This inability:
—was caused by an internal hydraulic leak
due to the deterioration of an O-ring seal
on a solenoid valve,
E:\FR\FM\09MYR1.SGM
09MYR1
27016
Federal Register / Vol. 78, No. 90 / Thursday, May 9, 2013 / Rules and Regulations
—was not detected by the PRIM 2 computer
nor announced to the flight crew.
• Incorrect Part Number (P/N) for solenoid
valve O-ring seals in IPC [illustrated parts
catalog]:
An incorrect O-ring seal P/N in IPC 27–34–
51–1 could have led to the installation of Oring seals incompatible with the hydraulic
fluid, causing them to deteriorate.
These conditions if not detected could lead
to the loss of elevator [control] on takeoff
and, potentially reduce the controllability of
the aeroplane.
The aim of EASA AD 2007–0009 was to:
—take over the requirements of AD F–2004–
158, and
—require the terminating action for § (1), (2)
and (4) of this [EASA] AD by introducing
new capped seals on solenoid valves for
A330–200 only.
This new [EASA] AD * * * requires the
embodiment of the latest software standard
on the three Flight Control Primary
Computers (FCPC) and on the two Flight
Control Secondary Computers (FCSC) [by
modifying the FCPCs and FCSCs] * * *.
The modification is accomplished
either by replacing the FCPCs and
FCSCs with new FCPCs and FCSCs, or
by replacing or reprogramming the onboard replaceable modules in the FCPCs
and FCSCs. Required actions also
include, depending on airplane
configuration, the following actions:
Revising the AFM to include certain
information; replacing certain O-rings;
and checking part number and replacing
certain O-ring seals if needed. You may
obtain further information by examining
the MCAI in the AD docket.
Comments
We gave the public the opportunity to
participate in developing this AD. We
considered the comments received.

Request for Exemption for Later
Standards of FCPC Software
Delta Air Lines, Inc. (Delta) requested
that we revise the NPRM (77 FR 48469,
August 14, 2012) to provide an
exemption for later standards of FCPC
software. Since completing Airbus
Mandatory Service Bulletin A330–27–
3148, Revision 01, dated October 9,
2008, Delta stated that it upgraded FCPC
software from standard P9/M18 to
newer standard P11A/M20A as
specified in Airbus Mandatory Service
Bulletin A330–27–3176, dated July 26,
2011. Delta noted that when there are
significant differences between the
airspeed sources, the autopilot (AP) and
the auto-thrust (A/THR) are designed to
disconnect, and the flight directors (FD)
bars are automatically removed. Delta
also noted that if two of the airspeed
sources then read similar, yet erroneous
numbers, the AP and A/THR will reengage, and the FD bars will reappear.
VerDate Mar<15>2010

Jkt 229001
Delta stated that this newer standard
addresses these safety concerns.
We agree to revise this AD to allow
modification of the FCPC with the
software identified in Airbus Mandatory
Service Bulletin A330–27–3176,
Revision 02, dated April 24, 2012, as
well as the software identified in Airbus
Mandatory Service Bulletin A330–27–
3177, dated December 21, 2011; Airbus
Mandatory Service Bulletin A340–27–
4174, dated November 21, 2011; and
Airbus Mandatory Service Bulletin
A340–27–4162, Revision 01, dated
September 17, 2012. We have added
paragraph (o) to this AD to specify that
modification of the three FCPC with
new software specified in paragraphs
(o)(1) through (o)(4) of this AD is
acceptable for compliance with the
requirements of paragraph (l) of this AD.
In addition, we have added new
paragraph (p)(4) of this AD to give credit
for performing actions before the
effective date of this AD using Airbus
Service Bulletin A330–27–3176, dated
July 26, 2011; Airbus Mandatory Service
Bulletin A330–27–3176, Revision 01,
dated March 27, 2012; and Airbus
Mandatory Service Bulletin A340–27–
4162, dated January 10, 2012.
We are also considering further
rulemaking that would correspond to
EASA AD 2011–0199R1, dated February
17, 2012, to mandate implementation of
these new FCPC standards.
Request for Credit for Modification of
FCPC Software Using Airbus
Mandatory Service Bulletin A330–27–
3148, Revision 01, October 9, 2008
Delta requested that we revise
paragraph (o)(2) of the NPRM (77 FR
48469, August 14, 2012) to give credit
for modification of FCPC software done
using Airbus Mandatory Service
Bulletin A330–27–3148, Revision 01,
dated October 9, 2008. This service
bulletin is the appropriate source of
service information for accomplishing
the actions required by paragraph (l) of
the NPRM. Delta stated that paragraph
(o)(2) of the NPRM provides credit, if
those actions were performed using
Airbus Service Bulletin A330–27–3144,
dated April 2, 2009, but there are no
statements giving credit for
modifications of the FCPC performed
using Airbus Mandatory Service
Bulletin A330–27–3148, Revision 01,
dated October 9, 2008.
We disagree with this request to
revise this AD, but agree to clarify that
this AD allows for previous
accomplishment of the modification
using Airbus Mandatory Service
Bulletin A330–27–3148, Revision 01,
dated October 9, 2008. Paragraph (l) of
this AD mandates modifications of

repeated, the intent of the comment is
addressed. No change has been made to
the AD in this regard.
Request for Credit for Modification of
FCSC Software Using Airbus Service
Bulletin A330–27–3145, Revision 1,
Dated July 17, 2008
Delta requested that we revise
paragraph (o)(3) of the NPRM (77 FR

December 16, 2008. Delta noted these
service bulletins are referred to as the
appropriate sources of service
information for accomplishing the
actions proposed by paragraph (m) of
the NPRM. Delta stated that paragraph
(o)(3) of the NPRM provides credit, if
those actions were performed using

Explanation of Change Made to This
AD
We have revised paragraph (n) of this
AD to put the AFM text into Figure 1
to paragraph (n) of this AD, and
included reference to the figure in that
paragraph. This change does not affect
the intent of that paragraph.
Conclusion
We reviewed the available data,
including the comments received, and
determined that air safety and the
public interest require adopting the AD
with the changes described previously—
VerDate Mar<15>2010
15:51 May 08, 2013
Jkt 229001
and minor editorial changes. We have
determined that these changes:
• Are consistent with the intent that
was proposed in the NPRM (77 FR
48469, August 14, 2012) for correcting
the unsafe condition; and
• Do not add any additional burden
upon the public than was already
proposed in the NPRM (77 FR 48469,
August 14, 2012).
Costs of Compliance
We estimate that this AD will affect
41 products of U.S. registry. We also
estimate that it will take about 5 workhours per product to comply with the
basic requirements of this AD. The
average labor rate is $85 per work-hour.
Required parts will cost about $0 per
product. Where the service information
lists required parts costs that are
covered under warranty, we have
assumed that there will be no charge for
these parts. As we do not control
warranty coverage for affected parties,
some parties may incur costs higher
than estimated here. Based on these
figures, we estimate the cost of this AD
to the U.S. operators to be $17,425, or
$425 per product.
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 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:
PO 00000
Frm 00017
Fmt 4700
Sfmt 4700
27017
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.
We prepared a regulatory evaluation
of the estimated costs to comply with
this AD and placed it in the AD docket.
Examining the AD Docket
You may examine the AD docket on
the Internet at https://
www.regulations.gov; or in person at the
Docket Operations office between 9 a.m.
and 5 p.m., Monday through Friday,

SUMMARY: We are adopting a new airworthiness directive (AD) for all
Airbus Model A330-200 and A330-300 series airplanes, and Model A340-200
and A340-300 series airplanes. This AD was prompted by reports of an
elevator blocked in the down position due to two independent failures;
first, the inability of a servo control to switch to active mode
because it was not detected by a flight control computer; and second,
an internal hydraulic leak due to the deterioration of an O-ring seal
on a solenoid. This AD requires, depending on airplane configuration,
modifying three flight control primary computers (FCPCs); modifying two
flight control secondary computers (FCSCs); revising the airplane
flight manual (AFM) to include certain information; replacing certain
O-rings; and checking part number and replacing certain O-ring seals if
needed. We are issuing this AD to detect and correct O-rings with
incorrect part numbers whose deterioration could lead to improper
sealing of solenoid valves; and to correct FCPC and FCSC software to
allow better control of elevator positioning; both conditions, if not
corrected, could lead to the loss of elevator control on takeoff, and
potentially reduce the controllability of the airplane.
DATES: This AD becomes effective June 13, 2013.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of June 13,
2013.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would apply to the specified products.
That NPRM was published in the Federal Register on August 14, 2012 (77
FR 48469). That NPRM proposed to correct an unsafe condition for the
specified products. The Mandatory Continuing Airworthiness Information
(MCAI) states:
This [European Aviation Safety Agency (EASA)] AD [2010-0081,
dated April 27, 2010] deals with the two following points:
Case of an elevator blocked in down position due to two
independent failures one of which is hidden:
Each elevator is controlled by two servo controls. In normal
operation:
--one servo control in active mode controlled by PRIM 1 (Green servo
control),
--one servo control in damping mode (Yellow or Blue servo control)
monitored by PRIM 2.
Change from active mode to damped mode is obtained by means of a
mode selector which is controlled by two identical solenoid valves
housed on the servo control. The sealing of each solenoid valve is
ensured by four O-ring seals.
During pre-flight control checks, the flight crew of an A330-200
aeroplane observed that one of the elevators was blocked in down
position, the ECAM [electronic centralized aircraft monitor] screen
displaying ``F/CTL PRIM 1 PITCH FAULT''.
This condition was due to two independent failures, one of which
was dormant, which occurred on one of the elevators.
Investigations revealed that the origin of the elevator
malfunction was due to the inability of the Yellow servo control to
switch to active mode.
This inability:
--was caused by an internal hydraulic leak due to the deterioration
of an O-ring seal on a solenoid valve,
[[Page 27016]]
--was not detected by the PRIM 2 computer nor announced to the
flight crew.
Incorrect Part Number (P/N) for solenoid valve O-ring
seals in IPC [illustrated parts catalog]:
An incorrect O-ring seal P/N in IPC 27-34-51-1 could have led to
the installation of O-ring seals incompatible with the hydraulic
fluid, causing them to deteriorate.
These conditions if not detected could lead to the loss of
elevator [control] on takeoff and, potentially reduce the
controllability of the aeroplane.
The aim of EASA AD 2007-0009 was to:
--take over the requirements of AD F-2004-158, and
--require the terminating action for Sec. (1), (2) and (4) of this
[EASA] AD by introducing new capped seals on solenoid valves for
A330-200 only.
This new [EASA] AD * * * requires the embodiment of the latest
software standard on the three Flight Control Primary Computers
(FCPC) and on the two Flight Control Secondary Computers (FCSC) [by
modifying the FCPCs and FCSCs] * * *.
The modification is accomplished either by replacing the FCPCs and
FCSCs with new FCPCs and FCSCs, or by replacing or reprogramming the
on-board replaceable modules in the FCPCs and FCSCs. Required actions
also include, depending on airplane configuration, the following
actions: Revising the AFM to include certain information; replacing
certain O-rings; and checking part number and replacing certain O-ring
seals if needed. You may obtain further information by examining the
MCAI in the AD docket.
Comments
We gave the public the opportunity to participate in developing
this AD. We considered the comments received.
Request for Exemption for Later Standards of FCPC Software
Delta Air Lines, Inc. (Delta) requested that we revise the NPRM (77
FR 48469, August 14, 2012) to provide an exemption for later standards
of FCPC software. Since completing Airbus Mandatory Service Bulletin
A330-27-3148, Revision 01, dated October 9, 2008, Delta stated that it
upgraded FCPC software from standard P9/M18 to newer standard P11A/M20A
as specified in Airbus Mandatory Service Bulletin A330-27-3176, dated
July 26, 2011. Delta noted that when there are significant differences
between the airspeed sources, the autopilot (AP) and the auto-thrust
(A/THR) are designed to disconnect, and the flight directors (FD) bars
are automatically removed. Delta also noted that if two of the airspeed
sources then read similar, yet erroneous numbers, the AP and A/THR will
re-engage, and the FD bars will reappear. Delta stated that this newer
standard addresses these safety concerns.
We agree to revise this AD to allow modification of the FCPC with
the software identified in Airbus Mandatory Service Bulletin A330-27-
3176, Revision 02, dated April 24, 2012, as well as the software
identified in Airbus Mandatory Service Bulletin A330-27-3177, dated
December 21, 2011; Airbus Mandatory Service Bulletin A340-27-4174,
dated November 21, 2011; and Airbus Mandatory Service Bulletin A340-27-
4162, Revision 01, dated September 17, 2012. We have added paragraph
(o) to this AD to specify that modification of the three FCPC with new
software specified in paragraphs (o)(1) through (o)(4) of this AD is
acceptable for compliance with the requirements of paragraph (l) of
this AD.
In addition, we have added new paragraph (p)(4) of this AD to give
credit for performing actions before the effective date of this AD
using Airbus Service Bulletin A330-27-3176, dated July 26, 2011; Airbus
Mandatory Service Bulletin A330-27-3176, Revision 01, dated March 27,
2012; and Airbus Mandatory Service Bulletin A340-27-4162, dated January
10, 2012.
We are also considering further rulemaking that would correspond to
EASA AD 2011-0199R1, dated February 17, 2012, to mandate implementation
of these new FCPC standards.
Request for Credit for Modification of FCPC Software Using Airbus
Mandatory Service Bulletin A330-27-3148, Revision 01, October 9, 2008
Delta requested that we revise paragraph (o)(2) of the NPRM (77 FR
48469, August 14, 2012) to give credit for modification of FCPC
software done using Airbus Mandatory Service Bulletin A330-27-3148,
Revision 01, dated October 9, 2008. This service bulletin is the
appropriate source of service information for accomplishing the actions
required by paragraph (l) of the NPRM. Delta stated that paragraph
(o)(2) of the NPRM provides credit, if those actions were performed
using Airbus Service Bulletin A330-27-3144, dated April 2, 2009, but
there are no statements giving credit for modifications of the FCPC
performed using Airbus Mandatory Service Bulletin A330-27-3148,
Revision 01, dated October 9, 2008.
We disagree with this request to revise this AD, but agree to
clarify that this AD allows for previous accomplishment of the
modification using Airbus Mandatory Service Bulletin A330-27-3148,
Revision 01, dated October 9, 2008. Paragraph (l) of this AD mandates
modifications of FCPC software using current revisions of the service
information, Airbus Service Bulletin A330-27-3144, Revision 01, dated
July 16, 2009; or Airbus Mandatory Service Bulletin A330-27-3148,
Revision 01, October 9, 2008. Paragraph (p)(2) of this AD (referred to
as paragraph (o)(2) in the NPRM (77 FR 48469, August 14, 2012)) gives
credit only for actions performed using previous revisions of the
service information specified in paragraph (l) of this AD, i.e., Airbus
Mandatory Service Bulletin A330-27-3144, dated April 2, 2009; and
Airbus Mandatory Service Bulletin A330-27-3148, dated July 17, 2008.
Since paragraph (f) of this AD indicates previous accomplishment of
modifications do not need to be repeated, the intent of the comment is
addressed. No change has been made to the AD in this regard.
Request for Credit for Modification of FCSC Software Using Airbus
Service Bulletin A330-27-3145, Revision 1, Dated July 17, 2008
Delta requested that we revise paragraph (o)(3) of the NPRM (77 FR

Revision 01, dated September 3, 2008; and Airbus Service Bulletin A330-
27-3145, dated December 16, 2008. Delta noted these service bulletins
are referred to as the appropriate sources of service information for
accomplishing the actions proposed by paragraph (m) of the NPRM. Delta
stated that paragraph (o)(3) of the NPRM provides credit, if those
actions were performed using Airbus Mandatory Service Bulletin A330-27-
3146, dated June 1, 2007, but pointed out that there are no statements
giving credit for modifications of the FCSC performed using Airbus
Mandatory Service Bulletin A330-27-3146, Revision 01, dated September
3, 2008.
We disagree with this request to revise this AD but agree to
clarify that this AD allows for previous accomplishment of the
modification using Airbus Mandatory Service Bulletin A330-27-3146,
Revision 01, dated September 3, 2008; and Airbus Service Bulletin A330-
27-3145, dated December 16, 2008. Paragraph (m) of this AD mandates
modifications of FCSC software using Airbus Mandatory Service Bulletin
A330-27-3146, Revision 01, dated September 3, 2008; or Airbus Service
Bulletin A330-27-3145, dated December 16, 2008. Paragraph (p)(3) of
this AD (referred to as paragraph (o)(3) in the NPRM (77 FR 48469,
August 14, 2012)) gives credit
[[Page 27017]]
only for actions performed using previous revisions of the service
information specified in paragraph (m) of this AD, i.e., Airbus Service
Bulletin A330-27-3146, dated June 1, 2007. Since paragraph (f) of this
AD indicates previous accomplishment of modifications do not need to be
repeated, the intent of the comment is addressed. No change has been
made to the AD in this regard.
Request for Credit for Installation of Modified Servo-Controls Using
Airbus Service Bulletin A330-27-3134, Revision 01, Dated May 12, 2006;
and Airbus Mandatory Service Bulletin A330-27-3136, Revision 1, Dated
July 19, 2006
Delta requested that we revise paragraph (p) of the NPRM (77 FR
48469, August 14, 2012) to give credit for the installation of modified
servo-controls done using Airbus Service Bulletin A330-27-3134,
Revision 01, dated May 12, 2006; and Airbus Mandatory Service Bulletin
A330-27-3136, Revision 01, dated July 19, 2006.
We disagree with this request to revise this AD, but agree to
clarify that this AD allows for previous accomplishment of the
installation using Airbus Service Bulletin A330-27-3134, Revision 01,
dated May 12, 2006; and Airbus Mandatory Service Bulletin A330-27-3136,
Revision 01, dated July 19, 2006. Paragraph (q) of this AD (referred to
as paragraph (p) of the NPRM (77 FR 48469, August 14, 2012)) provides
terminating action for the actions required by paragraphs (g), (h), and
(i) of this AD, if the installation of modified servo-controls was
using Airbus Service Bulletin A330-27-3134, Revision 01, dated May 12,
2006; and Airbus Mandatory Service Bulletin A330-27-3136, Revision 01,
dated July 19, 2006. Since paragraph (f) of this AD indicates previous
accomplishment of the installation not need to be repeated, the intent
of the comment is addressed. No change has been made to the AD in this
regard.
Explanation of Change Made to This AD
We have revised paragraph (n) of this AD to put the AFM text into
Figure 1 to paragraph (n) of this AD, and included reference to the
figure in that paragraph. This change does not affect the intent of
that paragraph.
Conclusion
We reviewed the available data, including the comments received,
and determined that air safety and the public interest require adopting
the AD with the changes described previously--and minor editorial
changes. We have determined that these changes:
Are consistent with the intent that was proposed in the
NPRM (77 FR 48469, August 14, 2012) for correcting the unsafe
condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM (77 FR 48469, August 14, 2012).
Costs of Compliance
We estimate that this AD will affect 41 products 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. The average labor rate
is $85 per work-hour. Required parts will cost about $0 per product.
Where the service information lists required parts costs that are
covered under warranty, we have assumed that there will be no charge
for these parts. As we do not control warranty coverage for affected
parties, some parties may incur costs higher than estimated here. Based
on these figures, we estimate the cost of this AD to the U.S. operators
to be $17,425, or $425 per product.
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 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.
We prepared a regulatory evaluation of the estimated costs to
comply with this AD and placed it in the AD docket.
Examining the AD Docket
You may examine the AD docket on the Internet at https://www.regulations.gov; or in person at the Docket Operations office
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The AD docket contains the NPRM (77 FR 48469, August 14,
2012), the regulatory evaluation, any comments received, and other
information. The street address for the Docket Operations office
(telephone (800) 647-5527) is in the ADDRESSES section. Comments will
be available in the AD docket shortly after receipt.

(d) Subject
Air Transport Association (ATA) of America Code 27: Flight
controls.
(e) Reason
This AD was prompted by reports of an elevator blocked in the
down position due to two independent failures; first, the inability
of a servo control to switch to active mode because it was not
detected by a flight control computer; and second, an internal
hydraulic leak due to the deterioration of an O-ring seal on a
solenoid. We are issuing this detect and correct O-rings with
incorrect part numbers whose deterioration could lead to improper
sealing of solenoid valves; and to correct flight control primary
computer (FCPC) and flight control secondary computer (FCSC)
software to allow better control of elevator positioning; both
conditions, if not corrected, could lead to the loss of elevator
control on takeoff, and potentially reduce the controllability of
the airplane.
(f) Compliance
You are responsible for having the actions required by this AD
performed within the compliance times specified, unless the actions
have already been done.
(g) Replacement of O-ring Seals for Elevator Servo Controls Installed
