In the incorrect formula, an ‘‘×’’
(multiplication) has been replaced with a ‘‘+’’
(addition) when the data was converted in
the system and if this formula is followed,
you may receive a result outside of the
allowed tolerance.
Incorrect balance, outside the tolerance of
the aileron control surface, may lead to
vibrations that in [the] worst case can result
in flutter.
The hard copy of the manual, SAAB 2000
SRM, is correct.
The CD/DVD dated Oct 01/05, marked
‘‘Reissue’’, includes a correct SAAB SRM
revision 22.
The corrective action includes identifying
ailerons that have been balanced after July 4,
2005, until the effective date of this AD. If
balanced incorrectly, they must be
rebalanced.
Actions and Compliance
(f) Within one month after the effective
date of this AD, unless already done, do the
following actions.
(1) Identify ailerons that have been
balanced after July 4, 2005. If balanced
incorrectly, they must be rebalanced before
further flight in accordance with Saab
Service Bulletin 2000–57–040, dated
February 23, 2006.
(2) As of the effective date of this AD, the
aileron balancing procedure contained in the
CD/DVD ‘‘Issue Date: Apr 01/05’’ including
the Saab SAAB 2000 SRM at Revision 21 and
the CD/DVD ‘‘Issue Date: Oct 01/05’’
including SRM at Revision 22 may not be
used.

Federal Register / Vol. 72, No. 191 / Wednesday, October 3, 2007 / Rules and Regulations
Discussion
The FAA issued a supplemental
notice of proposed rulemaking (NPRM)
to amend 14 CFR part 39 to include an
AD that supersedes AD 2006–15–09,
amendment 39–14689 (71 FR 42026,
July 25, 2006). The existing AD applies
to all Airbus Model A300, and Model
A310 airplanes; and Model A300 B4–
600, B4–600R, and F4–600R series
airplanes, and Model C4–605R Variant F
airplanes (collectively called A300–600
series airplanes). The supplemental
NPRM was published in the Federal
Register on June 20, 2007 (72 FR 33929).
The supplemental NPRM proposed to
require an inspection of the wing and
center fuel tanks to determine if certain
P-clips are installed and corrective
action if necessary; an inspection of
electrical bonding points of certain
equipment in the center fuel tank for the
presence of a blue coat and related
investigative and corrective actions if
necessary; and installation of new
bonding leads and electrical bonding
points on certain equipment in the
wing, center, and trim fuel tanks, as
necessary. That supplemental NPRM
also proposed to require, for certain
airplanes, installation of bonding on an
additional bracket; and for certain other
airplanes, modification of the fuel/
defuel valves on the left-hand wing.
Comments
We provided the public the
opportunity to participate in the
development of this AD. We have
considered the comments received.
Request To Revise Compliance Times
and To Put New Actions in a Separate
Rule
Air Transport Association (ATA), on
behalf of its member American Airlines
(AA), is concerned with the
administrative burden of the
supplemental NPRM. The commenters
point out that the supplemental NPRM
contains multiple compliance periods
for the required actions. The
commenters believe that the multiple
compliance periods should be
consolidated into one compliance
period. AA states that the scope of the
existing AD along with the work added
by the supplemental NPRM makes the
proposed AD unwieldy to implement.
AA states that considerable planning
and procurement schedules must be
accommodated for each additional AD,
which disrupts planning that is already
in place. The commenters state that the
scope change described in the
supplemental NPRM would have been
more appropriately mandated as a
separate rule.
We do not agree that the compliance
times should be consolidated into one
compliance period. In developing the
compliance time for this AD action, we
considered not only the safety
implications of the identified unsafe
condition, but the average utilization
rate of the affected fleet, the practical
aspects of an orderly inspection or
modification to the fleet during regular
maintenance periods, the availability of
required parts, and the time necessary
for the rulemaking process. We also
considered the compliance periods
specified by the European Aviation
Safety Agency (EASA) and the airplane
manufacturer. We have determined that
the proposed compliance times
following the effective date of the AD
are appropriate. We have not revised the
AD in this regard.
However, we do agree that the scope
change in the supplemental NPRM is
better mandated as a separate rule for
reasons the commenters stated. Since
we issued the supplemental NPRM, the
EASA has revised its airworthiness
directive to 2006–0325 R1, dated July
25, 2007. (We cited the original issue of
EASA airworthiness directive 2006–
0325, dated October 23, 2006, as the
parallel airworthiness directive in the
supplemental NPRM.) Revision 1 of the
EASA airworthiness directive removes
the procedures in Airbus Service
Bulletin A300–28–6064 from its stated
actions. Airbus Service Bulletin A300–
28–6064 includes procedures for Model
A300–600 series airplanes. That service
bulletin contains the scope change to
56259
which the commenters referred. R1 of
the EASA airworthiness directive also
removes Model A300–600 series
airplanes from its applicability. As a
result, we have revised the AD to do the
following:
• Remove paragraph (k) of the
supplemental NPRM. That paragraph
contains the scope change cited by the
commenters. We have re-identified
subsequent paragraphs accordingly.
• Remove Model A300–600 series
airplanes from the applicability. EASA
is considering additional rulemaking
regarding the unsafe condition for
Model A300–600 series airplanes. Once
the EASA airworthiness directive is
approved, we will consider additional
rulemaking for Model A300–600 series
airplanes.
• Remove Model A300–600 service
bulletins from Table 1 of the
supplemental NPRM.
• Remove the costs information for
Model A300–600 series airplanes from
the Costs of Compliance section.
• Revise the Related Information
(paragraph (n) of the supplemental
NPRM) to refer to Revision 1 of the
EASA airworthiness directive.
Conclusion
We have carefully 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. We have determined that
these changes will neither increase the
economic burden on any operator nor
increase the scope of the AD.
Costs of Compliance
There are about 92 Model A300 and
A310 airplanes of the affected design in
the U.S. fleet. The following table
provides the estimated costs, at an
average labor rate of $80 per hour, for
U.S. operators to comply with this AD.
For some actions, the estimated work
hours and cost of parts in the following

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 have 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
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 AD and placed it in the AD docket.
See the ADDRESSES section for a location
to examine the regulatory evaluation.

SUMMARY: The FAA is superseding two
existing airworthiness directives (ADs).
One AD applies to all Airbus Model
A319 and A320 airplanes and currently
requires repetitive ultrasonic
inspections to detect fatigue cracking in
the wing/fuselage joint cruciform
fittings, and corrective actions if
necessary. The other AD applies to all
Airbus Model A319, A320, and A321
airplanes and currently requires a
revision to the Airworthiness
Limitations section (ALS) of the
Instructions for Continued

Airworthiness (ICA). This new AD
requires new revisions to the ALS of the
ICA to incorporate service life limits for
certain items and inspections to detect
fatigue cracking, accidental damage, or
corrosion in certain structures; and
accomplishment of the repetitive
ultrasonic inspections of the wing/
fuselage joint cruciform fittings in
accordance with the revised ALS of the
ICA. This AD also adds airplanes to the
applicability. This AD results from
issuance of new and more restrictive
service life limits and structural
inspections based on fatigue testing and
in-service findings. We are issuing this
AD to detect and correct fatigue
cracking, accidental damage, or
corrosion in principal structural
elements and to prevent failure of
certain life limited parts, which could
result in reduced structural integrity of
the airplane.
DATES: This AD becomes effective
November 7, 2007.
The Director of the Federal Register
approved the incorporation by reference
of certain publications listed in the AD
as of November 7, 2007.

ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding an existing airworthiness directive
(AD) that applies to all Airbus Model A300 and A310 airplanes, and
certain Model A300-600 series airplanes. That AD currently requires an
inspection of the wing and center fuel tanks to determine if certain P-
clips are installed and corrective action if necessary. That AD also
requires an inspection of electrical bonding points of certain
equipment in the center fuel tank for the presence of a blue coat and
related investigative and corrective actions if necessary. That AD also
requires installation of new bonding leads and electrical bonding
points on certain equipment in the wing, center, and trim fuel tanks,
as necessary. This new AD requires, for certain airplanes, installation
of bonding on an additional bracket and modification of the fuel/defuel
valves on the left-hand wing. This AD results from fuel system reviews
conducted by the manufacturer. We are issuing this AD to ensure
continuous electrical bonding protection of equipment in the wing,
center, and trim fuel tanks and to prevent damage to wiring in the wing
and center fuel tanks, due to failed P-clips used for retaining the
wiring and pipes, which could result in a possible fuel ignition source
in the fuel tanks.
DATES: This AD becomes effective November 7, 2007.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of November 7,
2007.
On August 29, 2006 (71 FR 42026, July 25, 2006), the Director of

Discussion
The FAA issued a supplemental notice of proposed rulemaking (NPRM)
to amend 14 CFR part 39 to include an AD that supersedes AD 2006-15-09,
amendment 39-14689 (71 FR 42026, July 25, 2006). The existing AD
applies to all Airbus Model A300, and Model A310 airplanes; and Model
A300 B4-600, B4-600R, and F4-600R series airplanes, and Model C4-605R
Variant F airplanes (collectively called A300-600 series airplanes).
The supplemental NPRM was published in the Federal Register on June 20,
2007 (72 FR 33929). The supplemental NPRM proposed to require an
inspection of the wing and center fuel tanks to determine if certain P-
clips are installed and corrective action if necessary; an inspection
of electrical bonding points of certain equipment in the center fuel
tank for the presence of a blue coat and related investigative and
corrective actions if necessary; and installation of new bonding leads
and electrical bonding points on certain equipment in the wing, center,
and trim fuel tanks, as necessary. That supplemental NPRM also proposed
to require, for certain airplanes, installation of bonding on an
additional bracket; and for certain other airplanes, modification of
the fuel/defuel valves on the left-hand wing.
Comments
We provided the public the opportunity to participate in the
development of this AD. We have considered the comments received.
Request To Revise Compliance Times and To Put New Actions in a Separate
Rule
Air Transport Association (ATA), on behalf of its member American
Airlines (AA), is concerned with the administrative burden of the
supplemental NPRM. The commenters point out that the supplemental NPRM
contains multiple compliance periods for the required actions. The
commenters believe that the multiple compliance periods should be
consolidated into one compliance period. AA states that the scope of
the existing AD along with the work added by the supplemental NPRM
makes the proposed AD unwieldy to implement. AA states that
considerable planning and procurement schedules must be accommodated
for each additional AD, which disrupts planning that is already in
place. The commenters state that the scope change described in the
supplemental NPRM would have been more appropriately mandated as a
separate rule.
We do not agree that the compliance times should be consolidated
into one compliance period. In developing the compliance time for this
AD action, we considered not only the safety implications of the
identified unsafe condition, but the average utilization rate of the
affected fleet, the practical aspects of an orderly inspection or
modification to the fleet during regular maintenance periods, the
availability of required parts, and the time necessary for the
rulemaking process. We also considered the compliance periods specified
by the European Aviation Safety Agency (EASA) and the airplane
manufacturer. We have determined that the proposed compliance times
following the effective date of the AD are appropriate. We have not
revised the AD in this regard.
However, we do agree that the scope change in the supplemental NPRM
is better mandated as a separate rule for reasons the commenters
stated. Since we issued the supplemental NPRM, the EASA has revised its
airworthiness directive to 2006-0325 R1, dated July 25, 2007. (We cited
the original issue of EASA airworthiness directive 2006-0325, dated
October 23, 2006, as the parallel airworthiness directive in the
supplemental NPRM.) Revision 1 of the EASA airworthiness directive
removes the procedures in Airbus Service Bulletin A300-28-6064 from its
stated actions. Airbus Service Bulletin A300-28-6064 includes
procedures for Model A300-600 series airplanes. That service bulletin
contains the scope change to which the commenters referred. R1 of the
EASA airworthiness directive also removes Model A300-600 series
airplanes from its applicability. As a result, we have revised the AD
to do the following:
Remove paragraph (k) of the supplemental NPRM. That
paragraph contains the scope change cited by the commenters. We have
re-identified subsequent paragraphs accordingly.
Remove Model A300-600 series airplanes from the
applicability. EASA is considering additional rulemaking regarding the
unsafe condition for Model A300-600 series airplanes. Once the EASA
airworthiness directive is approved, we will consider additional
rulemaking for Model A300-600 series airplanes.
Remove Model A300-600 service bulletins from Table 1 of
the supplemental NPRM.
Remove the costs information for Model A300-600 series
airplanes from the Costs of Compliance section.
Revise the Related Information (paragraph (n) of the
supplemental NPRM) to refer to Revision 1 of the EASA airworthiness
directive.
Conclusion
We have carefully 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.
We have determined that these changes will neither increase the
economic burden on any operator nor increase the scope of the AD.
Costs of Compliance
There are about 92 Model A300 and A310 airplanes of the affected
design in the U.S. fleet. The following table provides the estimated
costs, at an average labor rate of $80 per hour, for U.S. operators to
comply with this AD. For some actions, the estimated work hours and
cost of parts in the following table depend on the airplane
configuration.

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 have 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 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 AD and placed it in the AD docket. See the ADDRESSES
section for a location to examine the regulatory evaluation.
