ACTION: Final rule.
AGENCY:
SUMMARY: We are adopting a new
airworthiness directive (AD) for the
products listed above. This 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 revealed that the control surface
balancing procedure in the * * * SAAB 2000
SRM (structural repair manual) * * * is
incorrect.
Incorrect balance, outside the tolerance of
the aileron control surface, may lead to
vibrations that in [the] worst case can result
in flutter.
We are issuing this AD to require
actions to correct the unsafe condition
on these products.
DATES: This AD becomes effective
November 7, 2007.
The Director of the Federal Register
approved the incorporation by reference
of a certain publication listed in this AD
as of November 7, 2007.

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 March 16, 2007 (72 FR
12576). That NPRM proposed to correct
an unsafe condition for the specified
products. The MCAI states:
It has been revealed that the control surface
balancing procedure in the Web and CD/DVD
versions of the SAAB 2000 SRM (structural
repair manual) Chapter 51–60–00, Control
Surface Balancing Procedure is incorrect. The
incorrect Calculation formula (page 1, 4 and
7) was incorporated in Revision 21 of the
SRM dated April 01/05 and was distributed
in 4 July 2005 on the CD/DVD issue Apr. 01/
05.
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. If balanced
incorrectly, they must be rebalanced.
Comments
We gave the public the opportunity to
participate in developing this AD. We
considered the comments received.
Request To Withdraw the NPRM
Saab points out that at the time
European Aviation Safety Agency
(EASA) issued Emergency
Airworthiness Directive 2006–0053–E,
dated February 22, 2006 (the MCAI), the
hard copy of the structural repair
manual (SRM) was correct but the Web
and CD/DVD versions had an incorrect
calculation formula. At that time, the
FAA did not issue an emergency AD
because there were only 3 of the affected
airplanes operating in the U.S. and the
E:\FR\FM\03OCR1.SGM
03OCR1
Federal Register / Vol. 72, No. 191 / Wednesday, October 3, 2007 / Rules and Regulations
operators stated that they had not used
the incorrect formula. The rest of the
affected fleet was operating in Europe
and subject to the EASA Emergency AD.
SAAB AB states that this means that no
affected airplane is operating with a
rigging performed according to the
incorrect formula. Saab recommends
that we withdraw the NPRM and do not
issue the AD.
We disagree with the request to
withdraw the NPRM. The number of
affected airplanes of U.S. registry has
grown from 3 to 7 in the past year, a
growth trend that could continue. We
cannot be certain that all airplanes that
are placed on the U.S. Register have had
the ailerons balanced correctly. Issuance
of this AD will ensure that airplanes
will be in compliance before being
permitted to operate in the U.S. We
have revised the Costs of Compliance
paragraph of this AD to reflect the
current number of U.S.-registered
airplanes. We have made no other
change to the AD in this regard.
Request To Refer to Later Revisions of
the CD/DVD
Saab requests that we change the
following phrase from paragraph (e) of
the NPRM: ‘‘The CD/DVD dated Oct 01/
05, marked ‘Reissue’, includes a correct
SAAB SRM revision 22.’’ Saab states
that the SRM has been revised a couple
of times since the MCAI was issued, and
that revision 23 and higher of the SRM
have the correct formula.
We acknowledge that revision 23 and
higher of the SRM also have the correct
formula. However, we have not revised
the text in paragraph (e) of the AD
because that text is simply a direct
quote from the MCAI. We have not
changed the AD in this regard.
ebenthall on PRODPC61 with RULES
Conclusion
We reviewed the available data,
including the comments received, and
determined that air safety and the
public interest require adopting the AD
as proposed.
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 required different
actions in this AD from those in the
MCAI in order to follow our FAA
VerDate Aug<31>2005
15:16 Oct 02, 2007
Jkt 214001
policies. Any such differences are
highlighted in a NOTE within the AD.
Costs of Compliance
Based on the service information, we
estimate that this AD affects about 7
products of U.S. registry. We also
estimate that it takes about 1 work-hour
per product to identify ailerons that
have been balanced after July 4, 2005.
The average labor rate is $80 per workhour. Based on these figures, we
estimate the cost of the AD for U.S.
operators to be $560, or $80 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 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); 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.

2007–20–06 Saab Aircraft AB: Amendment
39–15216. Docket No. FAA–2007–27595;
Directorate Identifier 2006–NM–248–AD.
Effective Date
(a) This airworthiness directive (AD)
becomes effective November 7, 2007.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Saab Model SAAB
2000 airplanes, certificated in any category,
ranging from serial number –004 through
–063, on which aileron, P/N (part number)
7357600–501/502, P/N 7357600–503/504,

is installed.
Subject
(d) Air Transport Association (ATA) of
America Code 57: Wings.
Reason
(e) The mandatory continuing
airworthiness information (MCAI) states:
It has been revealed that the control surface
balancing procedure in the web and CD/DVD
versions of the SAAB 2000 SRM (Structural
Repair Manual) Chapter 51–60–00, Control
Surface Balancing Procedure is incorrect. The
incorrect Calculation formula (page 1, 4 and
7) was incorporated in Revision 21 of the
SRM dated April 01/05 and was distributed
in 4 July 2005 on the CD/DVD issue Apr. 01/
05.
E:\FR\FM\03OCR1.SGM
03OCR1
56258
Federal Register / Vol. 72, No. 191 / Wednesday, October 3, 2007 / Rules and Regulations
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.

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

Request To Withdraw the NPRM
Saab points out that at the time European Aviation Safety Agency
(EASA) issued Emergency Airworthiness Directive 2006-0053-E, dated
February 22, 2006 (the MCAI), the hard copy of the structural repair
manual (SRM) was correct but the Web and CD/DVD versions had an
incorrect calculation formula. At that time, the FAA did not issue an
emergency AD because there were only 3 of the affected airplanes
operating in the U.S. and the
[[Page 56257]]
operators stated that they had not used the incorrect formula. The rest
of the affected fleet was operating in Europe and subject to the EASA
Emergency AD. SAAB AB states that this means that no affected airplane
is operating with a rigging performed according to the incorrect
formula. Saab recommends that we withdraw the NPRM and do not issue the
AD.
We disagree with the request to withdraw the NPRM. The number of
affected airplanes of U.S. registry has grown from 3 to 7 in the past
year, a growth trend that could continue. We cannot be certain that all
airplanes that are placed on the U.S. Register have had the ailerons
balanced correctly. Issuance of this AD will ensure that airplanes will
be in compliance before being permitted to operate in the U.S. We have
revised the Costs of Compliance paragraph of this AD to reflect the
current number of U.S.-registered airplanes. We have made no other
change to the AD in this regard.
Request To Refer to Later Revisions of the CD/DVD
Saab requests that we change the following phrase from paragraph
(e) of the NPRM: ``The CD/DVD dated Oct 01/05, marked `Reissue',
includes a correct SAAB SRM revision 22.'' Saab states that the SRM has
been revised a couple of times since the MCAI was issued, and that
revision 23 and higher of the SRM have the correct formula.
We acknowledge that revision 23 and higher of the SRM also have the
correct formula. However, we have not revised the text in paragraph (e)
of the AD because that text is simply a direct quote from the MCAI. We
have not changed the AD in this regard.
Conclusion
We reviewed the available data, including the comments received,
and determined that air safety and the public interest require adopting
the AD as proposed.
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 required different actions in this AD from those
in the MCAI in order to follow our FAA policies. Any such differences
are highlighted in a NOTE within the AD.
Costs of Compliance
Based on the service information, we estimate that this AD affects
about 7 products of U.S. registry. We also estimate that it takes about
1 work-hour per product to identify ailerons that have been balanced
after July 4, 2005. The average labor rate is $80 per work-hour. Based
on these figures, we estimate the cost of the AD for U.S. operators to
be $560, or $80 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 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); 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.
Examining the AD Docket
You may examine the AD docket on the Internet at https://
dms.dot.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, 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.

Adoption of the Amendment
0
Accordingly, under the authority delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
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]
0
2. The FAA amends Sec. 39.13 by adding the following new AD:
2007-20-06 Saab Aircraft AB: Amendment 39-15216. Docket No. FAA-
2007-27595; Directorate Identifier 2006-NM-248-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective November
7, 2007.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Saab Model SAAB 2000 airplanes,
certificated in any category, ranging from serial number -004
through -063, on which aileron, P/N (part number) 7357600-501/502,
P/N 7357600-503/504, P/N 7357600-505/506, P/N 7357600-507/508, P/N
7357991-601/602, P/N 7357991-603/604, P/N 7357991-605/606, P/N
7357995-843/844, or P/N 7357995-927/928, is installed.
Subject
(d) Air Transport Association (ATA) of America Code 57: Wings.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
It has been revealed that the control surface balancing
procedure in the web and CD/DVD versions of the SAAB 2000 SRM
(Structural Repair Manual) Chapter 51-60-00, Control Surface
Balancing Procedure is incorrect. The incorrect Calculation formula
(page 1, 4 and 7) was incorporated in Revision 21 of the SRM dated
April 01/05 and was distributed in 4 July 2005 on the CD/DVD issue
Apr. 01/05.
[[Page 56258]]
In the incorrect formula, an ``x'' (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.
