SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
PO 00000
Frm 00014
Fmt 4700
Sfmt 4700
part 39 to include an AD that would
apply to the specified products. That
NPRM was published in the Federal
Register on December 10, 2007 (72 FR
69628). That NPRM proposed to correct
an unsafe condition for the specified
products. The MCAI states:
Subsequent to accidents involving Fuel
Tank System explosions in flight * * * and
on ground, the FAA has published Special
Federal Aviation Regulation 88 (SFAR88) in
June 2001.
In their Letters referenced 04/00/02/07/01–
L296 dated March 4th, 2002 and 04/00/02/
07/03–L024, dated February 3rd, 2003, the
JAA (Joint Aviation Authorities)
recommended the application of a similar
regulation to the National Aviation
Authorities (NAA).
Under this regulation, all holders of type
certificates for passenger transport aircraft
with either a passenger capacity of 30 or
more, or a payload capacity of 7,500 pounds
(3402 kg) or more, which have received their
certification since January 1st, 1958, are
required to conduct a design review against
explosion risks.
This Airworthiness Directive (AD), which
renders mandatory the modification [6089] of
improving the sealing of Fuel Access Doors,
is a consequence of the design review.
The unsafe condition is the potential of
ignition sources inside fuel tanks,
which, in combination with flammable
fuel vapors, could result in fuel tank
explosions and consequent loss of the
airplane. Saab Modification 6089
includes removing the fuel tank access
doors and the old type of clamp rings
and gaskets; installing new, improved
clamp rings; re-installing the fuel tank
access doors; and doing related
investigative actions and applicable
corrective actions. Related investigative
actions and applicable corrective
actions include inspecting for corrosion
of the wing skin panel and access door
areas, and, as applicable, replacing wear
protection; contacting Saab and doing
repairs if doubler flange is less than
specified thickness; replacing any
corroded or damaged foil panel;
replacing any damaged sealing ring;
removing corrosion from the wing skin
panel; inspecting the access doors for
damage and correct installation of the
aluminum panel on the access door;
and, as applicable, replacing the
aluminum panel or the entire access
door. 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
received no comments on the NPRM or
on the determination of the cost to the
public.

Federal Register / Vol. 73, No. 24 / Tuesday, February 5, 2008 / Rules and Regulations
Conclusion
We reviewed the available data 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.
rmajette on PROD1PC64 with RULES
Costs of Compliance
We estimate that this AD will affect
about 6 products of U.S. registry. We
also estimate that it will take about 130
work-hours per product to comply with
the basic requirements of this AD. The
average labor rate is $80 per work-hour.
Required parts will cost about $6,400
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
$100,800, or $16,800 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://
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, 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.

SUMMARY: We are superseding an
existing airworthiness directive (AD) for
the products listed above. This AD
results from mandatory continuing
airworthiness information (MCAI)
issued 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 distortion of the rudder
bars due to rudder control forces during
aerobatic operation and nose wheel
steering reaction forces. Rudder bar
distortion could result in reduced
control or loss of control. This AD
requires actions that are intended to
address the unsafe condition described
in the MCAI.
DATES: This AD becomes effective
March 11, 2008.
As of March 11, 2008, the Director of
the Federal Register approved the
incorporation by reference of certain

SUPPLEMENTARY INFORMATION:
published in 1987 and AD 99–01–04,
Amendment 39–10971, published in
1999. That NPRM proposed to correct
an unsafe condition for the specified
products. The MCAI states that rudder
control forces during aerobatic
operation and nose wheel steering
reaction forces may cause rudder bar
distortion. Rudder bar distortion could
result in reduced control or loss of
control.
The MCAI requires you to replace the
left and right rudder bars with
reinforced rudder bars.
Comments
We gave the public the opportunity to
participate in developing this AD. We
received no comments on the NPRM or
on the determination of the cost to the
public.
Conclusion
We reviewed the available data 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

service information.
We might also have required 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 AD.
Costs of Compliance
We estimate that this AD will affect 9
products of U.S. registry. We also
estimate that it will take about 3 workhours per product to comply with basic
requirements of this AD. The average
labor rate is $80 per work-hour.
Required parts will cost about $657 per
product.
Based on these figures, we estimate
the cost of this AD to the U.S. operators
to be $8,073 or $897 per product.
Discussion

labor rate is $80 per work-hour. Required parts will cost about $6,400
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 $100,800, or $16,800 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://
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, 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:
2008-03-08 SAAB Aircraft AB: Amendment 39-15358. Docket No. FAA-
2007-0299; Directorate Identifier 2007-NM-239-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective March
11, 2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Saab Model SAAB 2000 airplanes, all
serial numbers, certificated in any category.
Subject
(d) Air Transport Association (ATA) of America Code 57: Wings.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
Subsequent to accidents involving Fuel Tank System explosions in
flight * * * and on ground, the FAA has published Special Federal
Aviation Regulation 88 (SFAR88) in June 2001.
In their Letters referenced 04/00/02/07/01-L296 dated March 4th,
2002 and 04/00/02/07/03-L024, dated February 3rd, 2003, the JAA
(Joint Aviation Authorities) recommended the application of a
similar regulation to the National Aviation Authorities (NAA).
Under this regulation, all holders of type certificates for
passenger transport aircraft with either a passenger capacity of 30
or more, or a payload capacity of 7,500 pounds (3402 kg) or more,
which have received their certification since January 1st, 1958, are
required to conduct a design review against explosion risks.
This Airworthiness Directive (AD), which renders mandatory the
modification [6089] of improving the sealing of Fuel Access Doors,
is a consequence of the design review.
The unsafe condition is the potential of ignition sources inside
fuel tanks, which, in combination with flammable fuel vapors, could
result in fuel tank explosions and consequent loss of the airplane.
Actions and Compliance
(f) Within 48 months after the effective date of this AD, unless
already done, do Modification 6089 and all related investigative
actions and applicable corrective actions, in accordance with the
Accomplishment Instructions of Saab Service Bulletin 2000-57-033,
dated March 2, 2000; or Revision 01, dated March 31, 2000. Do all
applicable related investigative and corrective actions before
further flight.
