AGENCY:
We propose to adopt a new
airworthiness directive (AD) for the
products listed above. This proposed
AD results from mandatory continuing
airworthiness information (MCAI)
originated by an aviation authority of
another country to identify and correct
an unsafe condition on an aviation
product. The MCAI describes the unsafe
condition as:
SUMMARY:
A number of occurrences of an incorrect
installation of the trimmable horizontal
stabilizer actuator (THSA) have been found
and reported during the accomplishment of
the AIRBUS Service Bulletin (SB) A320–27–
1164 mandated by EASA AD 2006–0223.
These issues could lead to a degradation of
the integrity of the THSA primary load path
and to secondary load path partial or full
engagement.
Degradation of the THSA primary
load path could result in latent
(undetected) loading and eventual
failure of the THSA secondary load
path, with consequent uncontrolled
movement of the horizontal stabilizer
and loss of control of the airplane. The
proposed AD would require actions that
are intended to address the unsafe
condition described in the MCAI.

Discussion
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Community, has issued EASA
Airworthiness Directive 2007–0178,
dated June 22, 2007 (referred to after
this as ‘‘the MCAI’’), to correct an unsafe
condition for the specified products.
The MCAI states:
A number of occurrences of an incorrect
installation of the trimmable horizontal
stabilizer actuator (THSA) have been found
and reported during the accomplishment of
the AIRBUS Service Bulletin (SB) A320–27–
1164 mandated by EASA AD 2006–0223.
These issues could lead to a degradation of
the integrity of the THSA primary load path
and to secondary load path partial or full
engagement.
E:\FR\FM\25OCP1.SGM
25OCP1
60592
Federal Register / Vol. 72, No. 206 / Thursday, October 25, 2007 / Proposed Rules
This AD therefore mandates a one-time
detailed visual inspection of specific parts of
the THSA attachments.
Degradation of the THSA primary
load path could result in latent
(undetected) loading and eventual
failure of the THSA secondary load
path, with consequent uncontrolled
movement of the horizontal stabilizer
and loss of control of the airplane. The
corrective actions include doing a onetime detailed visual inspection of the
lower and the upper THSA attachments
for correct installation and the presence
of metallic particles, contacting Airbus
for repair instructions if any installation
deviations or metallic particles are
found, and doing repairs. You may
obtain further information by examining
the MCAI in the AD docket.
Relevant Service Information
Airbus has issued Service Bulletin
A320–27A1179, dated January 12, 2007.
The actions described in this service
information are intended to correct the
unsafe condition identified in the
MCAI.
pwalker on PROD1PC71 with PROPOSALS
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 the same
type design.
Differences Between This AD and the
MCAI or Service Information
We have reviewed the MCAI and
related service information and, in
general, agree with their substance. But
we might have found it necessary to use
different words from those in the MCAI
to ensure the AD is clear for U.S.
operators and is enforceable. In making
these changes, we do not intend to differ
substantively from the information
provided in the MCAI and related
service information.
We might also have proposed
different actions in this AD from those
in the MCAI in order to follow FAA
policies. Any such differences are
highlighted in a NOTE within the
proposed AD.
Costs of Compliance
Based on the service information, we
estimate that this proposed AD would
VerDate Aug<31>2005
17:49 Oct 24, 2007
Jkt 214001
affect about 721 products of U.S.
registry. We also estimate that it would
take about 3 work-hours per product to
comply with the basic requirements of
this proposed AD. The average labor
rate is $80 per work-hour. Based on
these figures, we estimate the cost of the
proposed AD on U.S. operators to be
$173,040, or $240 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 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); and
3. 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 proposed AD and placed it in the
AD docket.

The Proposed Amendment
Accordingly, under the authority
delegated to me by the Administrator,
the FAA proposes to amend 14 CFR part
39 as follows:
PART 39—AIRWORTHINESS
DIRECTIVES
1. The authority citation for part 39
continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
§ 39.13
[Amended]
2. The FAA amends § 39.13 by adding
the following new AD:
AIRBUS: Docket No. FAA–2007–0081;
Directorate Identifier 2007–NM–186–AD.
Comments Due Date
(a) We must receive comments by
November 26, 2007.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Airbus A318, A319,
A320, and A321 series airplanes, certificated
in any category, all certified models, all
manufactured serial numbers (MSN) up to
and including MSN 2860.
Subject
(d) Air Transport Association (ATA) of
America Code 27: Flight Controls.
Reason
(e) The mandatory continuing
airworthiness information (MCAI) states:
A number of occurrences of an incorrect
installation of the trimmable horizontal
stabilizer actuator (THSA) have been found
and reported during the accomplishment of
the AIRBUS Service Bulletin (SB) A320–27–
1164 mandated by EASA AD 2006–0223.
These issues could lead to a degradation of
the integrity of the THSA primary load path
and to secondary load path partial or full
engagement.
This AD therefore mandates a one-time
detailed visual inspection of specific parts of
the THSA attachments.
Degradation of the THSA primary load path
could result in latent (undetected) loading
and eventual failure of the THSA secondary
load path, with consequent uncontrolled
movement of the horizontal stabilizer and
loss of control of the airplane. The corrective
actions include doing a one-time detailed
visual inspection of the lower and the upper
THSA attachments for correct installation
and the presence of metallic particles,
contacting Airbus for repair instructions if
any installation deviations or metallic
particles are found, and doing repairs.
Actions and Compliance
(f) Unless already done, do the following
actions.
(1) Within 600 flight hours or 750 flight
cycles or 100 days after the effective date of
this AD, whichever occurs first, inspect the
lower and the upper THSA attachments for
installation deviations and metallic particles,
E:\FR\FM\25OCP1.SGM
25OCP1
Federal Register / Vol. 72, No. 206 / Thursday, October 25, 2007 / Proposed Rules
in accordance with Airbus Service Bulletin
A320–27A1179, dated January 12, 2007; and,
if any installation deviations or metallic
particles are found, before further flight,
contact Airbus for repair instructions and
repair.
FAA AD Differences
Note: This AD differs from the MCAI and/
or service information as follows: No
Difference.
Other FAA AD Provisions
(g) The following provisions also apply to
this AD:
(1) Alternative Methods of Compliance
(AMOCs): The Manager, International
Branch, ANM–116, FAA, has the authority to
approve AMOCs for this AD, if requested
using the procedures found in 14 CFR 39.19.

ANM–116, Transport Airplane Directorate,
FAA, 1601 Lind Avenue, SW., Renton,
Washington 98057–3356; telephone (425)
227–2141; fax (425) 227–1149. Before using
any approved AMOC on any airplane to
which the AMOC applies, notify your
appropriate principal inspector (PI) in the
FAA Flight Standards District Office (FSDO),
or lacking a PI, your local FSDO.
(2) Airworthy Product: For any requirement
in this AD to obtain corrective actions from
a manufacturer or other source, use these
actions if they are FAA-approved. Corrective
actions are considered FAA-approved if they
are approved by the State of Design Authority
(or their delegated agent). You are required
to assure the product is airworthy before it
is returned to service.
(3) Reporting Requirements: For any
reporting requirement in this AD, under the
provisions of the Paperwork Reduction Act,
the Office of Management and Budget (OMB)
has approved the information collection
requirements and has assigned OMB Control
Number 2120–0056.

ACTION: Supplemental notice of

AGENCY:
SUMMARY: We are revising an earlier
NPRM for the products listed above.
This action revises the earlier NPRM by
expanding the scope. This proposed AD
results from mandatory continuing
airworthiness information (MCAI)
originated by an aviation authority of
another country to identify and correct
an unsafe condition on an aviation
product. The MCAI describes the unsafe
condition as:
It has been found that some ‘‘caution’’
messages issued by the Flight Guidance
Control System (FGCS) are not displayed on
aircraft equipped with [certain] EPIC
software load[s] * * *. Therefore, following
a possible failure on one FGCS channel
during a given flight, such a failure condition
will remain undetected * * *. If another
failure occurs on the second FGCS channel,
the result may be a command hardover by the
autopilot.
A command hardover is a sudden roll,
pitch, or yaw movement, which could
result in reduced controllability of the
airplane. The proposed AD would
require actions that are intended to
address the unsafe condition described
in the MCAI.

Discussion
We proposed to amend 14 CFR part
39 with an earlier NPRM for the
specified products, which was
published in the Federal Register on
April 6, 2007 (72 FR 17042). That earlier
NPRM proposed to require actions
intended to address the unsafe
condition for the products listed above.
Since that NPRM was issued,
EMBRAER Model ERJ 190–200 STD,
–200 LR, and –200 IGW airplanes have
been added to the U.S. type certificate
data sheet. We have determined that
these airplane models are subject to the
unsafe condition and are included in
the MCAI for Model 190 airplanes.

after this as ``the MCAI''), to correct an unsafe condition for the
specified products. The MCAI states:
A number of occurrences of an incorrect installation of the
trimmable horizontal stabilizer actuator (THSA) have been found and
reported during the accomplishment of the AIRBUS Service Bulletin
(SB) A320-27-1164 mandated by EASA AD 2006-0223.
These issues could lead to a degradation of the integrity of the
THSA primary load path and to secondary load path partial or full
engagement.
[[Page 60592]]
This AD therefore mandates a one-time detailed visual inspection
of specific parts of the THSA attachments.
Degradation of the THSA primary load path could result in latent
(undetected) loading and eventual failure of the THSA secondary load
path, with consequent uncontrolled movement of the horizontal
stabilizer and loss of control of the airplane. The corrective actions
include doing a one-time detailed visual inspection of the lower and
the upper THSA attachments for correct installation and the presence of
metallic particles, contacting Airbus for repair instructions if any
installation deviations or metallic particles are found, and doing
repairs. You may obtain further information by examining the MCAI in
the AD docket.
Relevant Service Information
Airbus has issued Service Bulletin A320-27A1179, dated January 12,
2007. The actions described in this service information are intended to
correct the unsafe condition identified in the MCAI.
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 the same
type design.
Differences Between This AD and the MCAI or Service Information
We have reviewed the MCAI and related service information and, in
general, agree with their substance. But we might have found it
necessary to use different words from those in the MCAI to ensure the
AD is clear for U.S. operators and is enforceable. In making these
changes, we do not intend to differ substantively from the information
provided in the MCAI and related service information.
We might also have proposed different actions in this AD from those
in the MCAI in order to follow FAA policies. Any such differences are
highlighted in a NOTE within the proposed AD.
Costs of Compliance
Based on the service information, we estimate that this proposed AD
would affect about 721 products of U.S. registry. We also estimate that
it would take about 3 work-hours per product to comply with the basic
requirements of this proposed AD. The average labor rate is $80 per
work-hour. Based on these figures, we estimate the cost of the proposed
AD on U.S. operators to be $173,040, or $240 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 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); and
3. 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 proposed AD and placed it in the AD docket.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Safety.
The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
2. The FAA amends Sec. 39.13 by adding the following new AD:
AIRBUS: Docket No. FAA-2007-0081; Directorate Identifier 2007-NM-
186-AD.
Comments Due Date
(a) We must receive comments by November 26, 2007.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Airbus A318, A319, A320, and A321 series
airplanes, certificated in any category, all certified models, all
manufactured serial numbers (MSN) up to and including MSN 2860.
Subject
(d) Air Transport Association (ATA) of America Code 27: Flight
Controls.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
A number of occurrences of an incorrect installation of the
trimmable horizontal stabilizer actuator (THSA) have been found and
reported during the accomplishment of the AIRBUS Service Bulletin
(SB) A320-27-1164 mandated by EASA AD 2006-0223.
These issues could lead to a degradation of the integrity of the
THSA primary load path and to secondary load path partial or full
engagement.
This AD therefore mandates a one-time detailed visual inspection
of specific parts of the THSA attachments.
Degradation of the THSA primary load path could result in latent
(undetected) loading and eventual failure of the THSA secondary load
path, with consequent uncontrolled movement of the horizontal
stabilizer and loss of control of the airplane. The corrective
actions include doing a one-time detailed visual inspection of the
lower and the upper THSA attachments for correct installation and
the presence of metallic particles, contacting Airbus for repair
instructions if any installation deviations or metallic particles
are found, and doing repairs.
Actions and Compliance
(f) Unless already done, do the following actions.
(1) Within 600 flight hours or 750 flight cycles or 100 days
after the effective date of this AD, whichever occurs first, inspect
the lower and the upper THSA attachments for installation deviations
and metallic particles,
[[Page 60593]]
in accordance with Airbus Service Bulletin A320-27A1179, dated
January 12, 2007; and, if any installation deviations or metallic
particles are found, before further flight, contact Airbus for
repair instructions and repair.
