SUPPLEMENTARY INFORMATION:
Discussion
We issued a supplemental notice of
proposed rulemaking (NPRM) to amend
14 CFR part 39 to include an AD that
would apply to the specified products.
That supplemental NPRM was
published in the Federal Register on
March 6, 2008 (73 FR 12034). That
supplemental 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 published Special
Federal Aviation Regulation 88 (SFAR 88) in
June 2001. SFAR 88 required a safety review
of the aircraft Fuel Tank System to determine
that the design meets the requirements of
FAR (Federal Aviation Regulation) § 25.901
and § 25.981(a) and (b).
A similar regulation has been
recommended by the JAA (Joint Aviation
Authorities) to the European National
Aviation Authorities in JAA letter 04/00/02/
07/03–L024 of 3 February 2003. The review
was requested to be mandated by NAA’s
(National Aviation Authorities) using JAR
(Joint Aviation Regulation) § 25.901(c),
§ 25.1309.
In August 2005 EASA published a policy
statement on the process for developing
instructions for maintenance and inspection
of Fuel Tank System ignition source
prevention (EASA D 2005/CPRO,
www.easa.eu.int/home/
cert_policy_statements_en.html) that also
included the EASA expectations with regard
to compliance times of the corrective actions
on the unsafe and the not unsafe part of the
harmonised design review results. On a
global scale the TC (type certificate) holders
committed themselves to the EASA
published compliance dates (see EASA
policy statement). The EASA policy
statement has been revised in March 2006:
the date of 31–12–2005 for the unsafe related
actions has now been set at 01–07–2006.
Fuel Airworthiness Limitations are items
arising from a systems safety analysis that
have been shown to have failure mode(s)
associated with an ‘unsafe condition’ as
defined in FAA’s memo 2003–112–15 ‘SFAR
88—Mandatory Action Decision Criteria’.
These are identified in Failure Conditions for
which an unacceptable probability of ignition
risk could exist if specific tasks and/or
practices are not performed in accordance
with the manufacturers’ requirements.

This EASA Airworthiness Directive
mandates the Fuel System Airworthiness
Limitations (comprising maintenance/
inspection tasks and Critical Design
Configuration Control Limitations (CDCCL))
for the type of aircraft, that resulted from the
design reviews and the JAA recommendation
and EASA policy statement mentioned
above.
The corrective action is revising the
Airworthiness Limitations Section of
the Instructions for Continued
Airworthiness to incorporate new
limitations for fuel tank systems. 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.
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.
Costs of Compliance
We estimate that this AD will affect
about 144 products of U.S. registry. We
also estimate that it will take about 1
work-hour per product to comply with
the basic requirements of this AD. The
average labor rate is $80 per work-hour.
Based on these figures, we estimate the
cost of this AD to the U.S. operators to
be $11,520, 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.
E:\FR\FM\28APR1.SGM
28APR1
22790
Federal Register / Vol. 73, No. 82 / Monday, April 28, 2008 / Rules and Regulations
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.

PART 39—AIRWORTHINESS
DIRECTIVES
1. The authority citation for part 39
continues to read as follows:
I
Authority: 49 U.S.C. 106(g), 40113, 44701.
§ 39.13
[Amended]
2. The FAA amends § 39.13 by adding
the following new AD:

2008–09–06 Saab Aircraft AB: Amendment
39–15487. Docket No. FAA–2007–29248;
Directorate Identifier 2007–NM–155–AD.
Effective Date
(a) This airworthiness directive (AD)
becomes effective June 2, 2008.
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.
Affected ADs
(b) None.
Examining the AD Docket
Reason
(e) The mandatory continuing
airworthiness information (MCAI) states:
Subsequent to accidents involving Fuel
Tank System explosions in flight * * * and
on ground, the FAA published Special
Federal Aviation Regulation 88 (SFAR 88) in
June 2001. SFAR 88 required a safety review
of the aircraft Fuel Tank System to determine
that the design meets the requirements of
FAR (Federal Aviation Regulation) § 25.901
and § 25.981(a) and (b).
A similar regulation has been
recommended by the JAA (Joint Aviation
Authorities) to the European National
Aviation Authorities in JAA letter 04/00/02/
07/03–L024 of 3 February 2003. The review
was requested to be mandated by NAA’s
(National Aviation Authorities) using JAR
(Joint Aviation Regulation) § 25.901(c),
§ 25.1309.
In August 2005 EASA published a policy
statement on the process for developing
instructions for maintenance and inspection
of Fuel Tank System ignition source

Applicability
(c) This AD applies to all Saab Model
SAAB-Fairchild SF340A (SAAB/SF340A)
and SAAB 340B airplanes, certificated in any
category, all serial numbers.
Note 1: This AD requires revisions to
certain operator maintenance documents to
include new inspections. Compliance with
these inspections is required by 14 CFR
91.403(c). For airplanes that have been
previously modified, altered, or repaired in
the areas addressed by these inspections, the
operator may not be able to accomplish the
inspections described in the revisions. In this
situation, to comply with 14 CFR 91.403(c),
the operator must request approval for an
alternative method of compliance according
to paragraph (g)(1) of this AD. The request
should include a description of changes to
the required inspections that will ensure the
continued operational safety of the airplane.

included the EASA expectations with regard
to compliance times of the corrective actions
on the unsafe and the not unsafe part of the
harmonised design review results. On a
global scale the TC (type certificate) holders
committed themselves to the EASA
published compliance dates (see EASA
policy statement). The EASA policy
statement has been revised in March 2006:
the date of 31–12–2005 for the unsafe related
actions has now been set at 01–07–2006.
Fuel Airworthiness Limitations are items
arising from a systems safety analysis that
have been shown to have failure mode(s)
associated with an ‘unsafe condition’ as
defined in FAA’s memo 2003–112–15 ‘SFAR
88—Mandatory Action Decision Criteria’.
These are identified in Failure Conditions for
which an unacceptable probability of ignition
risk could exist if specific tasks and/or
practices are not performed in accordance
with the manufacturers’ requirements.
This EASA Airworthiness Directive
mandates the Fuel System Airworthiness
Limitations (comprising maintenance/
inspection tasks and Critical Design
Configuration Control Limitations (CDCCL))
for the type of aircraft, that resulted from the
design reviews and the JAA recommendation
and EASA policy statement mentioned
above.
The corrective action is revising the
Airworthiness Limitations Section of the
Instructions for Continued Airworthiness to
incorporate new limitations for fuel tank
systems.
Actions and Compliance
(f) Unless already done, do the following
actions.
(1) Before December 16, 2008, or within 3
months after the effective date of this AD,
whichever occurs earlier, revise the

SUMMARY: We are adopting a new
airworthiness directive (AD) for the
specified Agusta S.p.A. (Agusta) model
helicopters. This AD results from
mandatory continuing airworthiness
information (MCAI) originated by an
aviation authority to identify and
correct an unsafe condition on an
aviation product. The European
Aviation Safety Agency (EASA), the
Technical Agent for Italy, with which
we have a bilateral agreement, states in
the MCAI:
It has been reported, on an A109A
helicopter, a case of failure of the grooved
clamp fixing the engine exhaust duct, with
the consequent loss of the duct.
The duct has hit the main and tail rotor
producing the loss of the tail rotor and the
emergency landing of the helicopter.
The fracture of the grooved clamp was
due to excessive loads and corrosion
around the attaching rivets. This AD
requires actions that are intended to
address this unsafe condition.

SUPPLEMENTARY INFORMATION:
Streamlined Issuance of AD
The FAA is implementing a new
process for streamlining the issuance of
ADs related to MCAI. This streamlined
process will allow us to adopt MCAI
safety requirements in a more efficient
manner and will reduce safety risks to
the public. This process continues to
follow all FAA AD issuance processes to
meet legal, economic, Administrative
Procedure Act, and Federal Register
requirements. We also continue to meet
our technical decision-making
responsibilities to identify and correct
unsafe conditions on U.S.-certificated
products.
This AD references the MCAI and
related service information that we
considered in forming the engineering
basis to correct the unsafe condition.
The AD contains text copied from the
MCAI and for this reason might not
follow our plain language principles.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a supplemental notice of proposed rulemaking (NPRM) to
amend 14 CFR part 39 to include an AD that would apply to the specified
products. That supplemental NPRM was published in the Federal Register
on March 6, 2008 (73 FR 12034). That supplemental 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 published Special Federal
Aviation Regulation 88 (SFAR 88) in June 2001. SFAR 88 required a
safety review of the aircraft Fuel Tank System to determine that the
design meets the requirements of FAR (Federal Aviation Regulation)
Sec. 25.901 and Sec. 25.981(a) and (b).
A similar regulation has been recommended by the JAA (Joint
Aviation Authorities) to the European National Aviation Authorities
in JAA letter 04/00/02/07/03-L024 of 3 February 2003. The review was
requested to be mandated by NAA's (National Aviation Authorities)
using JAR (Joint Aviation Regulation) Sec. 25.901(c), Sec.
25.1309.
In August 2005 EASA published a policy statement on the process
for developing instructions for maintenance and inspection of Fuel
Tank System ignition source prevention (EASA D 2005/CPRO,
www.easa.eu.int/home/cert_policy_statements_en.html) that also
included the EASA expectations with regard to compliance times of
the corrective actions on the unsafe and the not unsafe part of the
harmonised design review results. On a global scale the TC (type
certificate) holders committed themselves to the EASA published
compliance dates (see EASA policy statement). The EASA policy
statement has been revised in March 2006: the date of 31-12-2005 for
the unsafe related actions has now been set at 01-07-2006.
Fuel Airworthiness Limitations are items arising from a systems
safety analysis that have been shown to have failure mode(s)
associated with an `unsafe condition' as defined in FAA's memo 2003-
112-15 `SFAR 88--Mandatory Action Decision Criteria'. These are
identified in Failure Conditions for which an unacceptable
probability of ignition risk could exist if specific tasks and/or
practices are not performed in accordance with the manufacturers'
requirements.
This EASA Airworthiness Directive mandates the Fuel System
Airworthiness Limitations (comprising maintenance/inspection tasks
and Critical Design Configuration Control Limitations (CDCCL)) for
the type of aircraft, that resulted from the design reviews and the
JAA recommendation and EASA policy statement mentioned above.
The corrective action is revising the Airworthiness Limitations Section
of the Instructions for Continued Airworthiness to incorporate new
limitations for fuel tank systems. 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.
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.
Costs of Compliance
We estimate that this AD will affect about 144 products of U.S.
registry. We also estimate that it will take about 1 work-hour per
product to comply with the basic requirements of this AD. The average
labor rate is $80 per work-hour. Based on these figures, we estimate
the cost of this AD to the U.S. operators to be $11,520, 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.
[[Page 22790]]
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.
List of Subjects in 14 CFR Part 39

reference, Safety.
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:
2008-09-06 Saab Aircraft AB: Amendment 39-15487. Docket No. FAA-
2007-29248; Directorate Identifier 2007-NM-155-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective June 2,
2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to all Saab Model SAAB-Fairchild SF340A
(SAAB/SF340A) and SAAB 340B airplanes, certificated in any category,
all serial numbers.
Note 1: This AD requires revisions to certain operator
maintenance documents to include new inspections. Compliance with
these inspections is required by 14 CFR 91.403(c). For airplanes
that have been previously modified, altered, or repaired in the
areas addressed by these inspections, the operator may not be able
to accomplish the inspections described in the revisions. In this
situation, to comply with 14 CFR 91.403(c), the operator must
request approval for an alternative method of compliance according
to paragraph (g)(1) of this AD. The request should include a
description of changes to the required inspections that will ensure
the continued operational safety of the airplane.
Subject
(d) Air Transport Association (ATA) of America Code 28: Fuel.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
Subsequent to accidents involving Fuel Tank System explosions in
flight * * * and on ground, the FAA published Special Federal
Aviation Regulation 88 (SFAR 88) in June 2001. SFAR 88 required a
safety review of the aircraft Fuel Tank System to determine that the
design meets the requirements of FAR (Federal Aviation Regulation)
Sec. 25.901 and Sec. 25.981(a) and (b).
A similar regulation has been recommended by the JAA (Joint
Aviation Authorities) to the European National Aviation Authorities
in JAA letter 04/00/02/07/03-L024 of 3 February 2003. The review was
requested to be mandated by NAA's (National Aviation Authorities)
using JAR (Joint Aviation Regulation) Sec. 25.901(c), Sec.
25.1309.
In August 2005 EASA published a policy statement on the process
for developing instructions for maintenance and inspection of Fuel
Tank System ignition source prevention (EASA D 2005/CPRO,
www.easa.eu.int/home/cert_policy_statements_en.html) that also
included the EASA expectations with regard to compliance times of
the corrective actions on the unsafe and the not unsafe part of the
harmonised design review results. On a global scale the TC (type
certificate) holders committed themselves to the EASA published
compliance dates (see EASA policy statement). The EASA policy
statement has been revised in March 2006: the date of 31-12-2005 for
the unsafe related actions has now been set at 01-07-2006.
Fuel Airworthiness Limitations are items arising from a systems
safety analysis that have been shown to have failure mode(s)
associated with an `unsafe condition' as defined in FAA's memo 2003-
112-15 `SFAR 88--Mandatory Action Decision Criteria'. These are
identified in Failure Conditions for which an unacceptable
probability of ignition risk could exist if specific tasks and/or
practices are not performed in accordance with the manufacturers'
requirements.
This EASA Airworthiness Directive mandates the Fuel System
Airworthiness Limitations (comprising maintenance/inspection tasks
and Critical Design Configuration Control Limitations (CDCCL)) for
the type of aircraft, that resulted from the design reviews and the
JAA recommendation and EASA policy statement mentioned above.
The corrective action is revising the Airworthiness Limitations
Section of the Instructions for Continued Airworthiness to
incorporate new limitations for fuel tank systems.
Actions and Compliance
(f) Unless already done, do the following actions.
(1) Before December 16, 2008, or within 3 months after the
effective date of this AD, whichever occurs earlier, revise the
Airworthiness Limitations Section (ALS) of the Instructions for
Continued Airworthiness to incorporate the maintenance and
inspection instructions in Part 1 of Saab 340 Fuel Airworthiness
Limitations Document 340 LKS 009033, dated February 14, 2006. For
all tasks identified in Part 1 of Saab 340 Fuel Airworthiness
Limitations Document 340 LKS 009033, dated February 14, 2006, the
initial compliance times start from the effective date of this AD,
and the repetitive inspections must be accomplished thereafter at
the interval specified in Part 1 of Saab 340 Fuel Airworthiness
Limitations Document 340 LKS 009033, dated February 14, 2006; except
as provided by paragraphs (f)(3) and (g) of this AD.
(2) Before December 16, 2008, revise the ALS of the Instructions
for Continued Airworthiness to incorporate the CDCCLs as defined in
Part 2 of Saab 340 Fuel Airworthiness Limitations Document 340 LKS
009033, dated February 14, 2006.
(3) After accomplishing the actions specified in paragraphs
(f)(1) and (f)(2) of this AD, no alternative inspection, inspection
intervals, or CDCCLs may be used unless the inspections, intervals,
or CDCCLs are part of a later revision of Saab 340 Fuel
Airworthiness Limitations Document 340 LKS 009033, dated February
14, 2006, that is approved by the Manager, International Branch,
ANM-116, Transport Airplane
[[Page 22791]]
Directorate, FAA, or the European Aviation Safety Agency (EASA) (or
its delegated agent); or unless the inspections, intervals, or
CDCCLs are approved as an alternative method of compliance (AMOC) in
accordance with the procedures specified in paragraph (g)(1) of this
AD.
(4) Where Saab 340 Fuel Airworthiness Limitations Document 340
LKS 009033, dated February 14, 2006, allows for exceptional short-
term extensions, an exception is acceptable to the FAA if it is
approved by the appropriate principal inspector in the FAA Flight
Standards Certificate Holding District Office.
