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 14, 2008 (73 FR
13800). That NPRM proposed to correct
an unsafe condition for the specified
products. The MCAI states:
Two of the fasteners used to attach the
‘‘scissors’’ to the horizontal and the vertical
stabilizers were found broken during routine
maintenance. The highest loads on the
‘‘scissors’’ occur when using high reverse
thrust. Therefore, the reverse thrust must be
limited to idle in order to keep the loads at
a sufficiently low level to preclude any
structural problem. It was established that on
model 1125 Astra, alternate fasteners of
inferior strength were sometimes installed.
When the originally specified fasteners are
installed, the limitations on reverse thrust
used may be lifted. For models Astra SPX
and G100, however, the limitation remains in
effect till further revision of this AD.

Failure of the attachment fasteners
could result in possible in-flight loss of
a horizontal or vertical stabilizer and
consequent loss of control of the
airplane. Corrective actions include
revising the airplane flight manual
(AFM); inspections for damage of the
bolts and replacing the bolt, if
necessary; and doing related
investigative and other corrective
actions (eddy current inspection for bolt
hole diameter and damage, contact
Gulfstream for repair and do repair).
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 129 products of U.S. registry. We
also estimate that it will take about 10
E:\FR\FM\08JYR1.SGM
08JYR1
Federal Register / Vol. 73, No. 131 / Tuesday, July 8, 2008 / Rules and Regulations
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 $33 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 $107,457, or
$833 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.
ebenthall on PRODPC60 with RULES
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.

Adoption of the Amendment
Accordingly, under the authority
delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as
follows:
I
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:
I
2008–13–30 Gulfstream Aerospace LP
(Formerly Israel Aircraft Industries,
Ltd.): Amendment 39–15593. Docket No.
FAA–2008–0299; Directorate Identifier
2007–NM–254–AD.
Effective Date
(a) This airworthiness directive (AD)
becomes effective August 12, 2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Gulfstream
Aerospace LP Model Astra SPX, 1125
Westwind Astra, and Gulfstream 100
airplanes; certificated in any category; serial
numbers 004 through 158.
Subject
(d) Air Transport Association (ATA) of
America Code 55: Stabilizers.
Reason
(e) The mandatory continuing
airworthiness information (MCAI) states:
Two of the fasteners used to attach the
‘‘scissors’’ to the horizontal and the vertical
stabilizers were found broken during routine
maintenance. The highest loads on the
‘‘scissors’’ occur when using high reverse
thrust. Therefore, the reverse thrust must be
limited to idle in order to keep the loads at
a sufficiently low level to preclude any
structural problem. It was established that on
PO 00000
Frm 00017
Fmt 4700
Sfmt 4700
38899
model 1125 Astra, alternate fasteners of
inferior strength were sometimes installed.
When the originally specified fasteners are
installed, the limitations on reverse thrust
used may be lifted. For models Astra SPX
and G100, however, the limitation remains in
effect till further revision of this AD.
Failure of the attachment fasteners could
result in possible in-flight loss of a horizontal
or vertical stabilizer and consequent loss of
control of the airplane. Corrective actions
include revising the airplane flight manual
(AFM); inspections for damage of the bolts
and replacing the bolt, if necessary; and
doing related investigative and other
corrective actions (eddy current inspection
for bolt hole diameter and damage, contact
Gulfstream for repair and do repair).
Actions and Compliance
(f) Unless already done, do the following
actions.
(1) Within 30 days after the effective date
of this AD: Revise the Limitations section of
the AFM by incorporating the information in
the applicable Israel Aircraft Industries
(Gulfstream) temporary revisions (TR): Astra
AFM TR 15; Astra SPX AFM TR 8; or
Gulfstream 100 AFM TR 1; all dated June 14,
2007; into the Limitations section of the
Gulfstream Astra, Astra SPX, or Gulfstream
100 AFM, as applicable. The TRs limit the
normal use of reverse thrust to idle.
Note 1: The actions required by paragraph
(f) of this AD may be done by inserting a
copy of Israel Aircraft Industries (Gulfstream)
Astra AFM TR 15; Astra SPX AFM TR 8; or
Gulfstream 100 AFM TR 1; all dated June 14,
2007; as applicable; into the Limitations
section of the Gulfstream Astra, Astra SPX,
or Gulfstream 100 AFM, as applicable. When
the applicable TR has been included in the
general revisions of the applicable AFM, the
general revisions may be inserted in the
AFM.
(2) For all airplanes: Within 25 flight hours
or 30 days after the effective date of this AD,
whichever comes first, do the inspections
specified in paragraphs (f)(2)(i) and (f)(2)(ii)
of this AD in accordance with Part A of
Gulfstream Alert Service Bulletin 100–55A–
293, dated June 22, 2007.
(i) Visually inspect the attachment bolts
and replace any damaged bolt before further
flight.
(ii) Perform a detailed visual inspection of
fittings with part number (P/N) 25W357222–
501–51, and fillers with P/N 25W4011001–
003, and surrounding structure for damage. If
blind bolts with P/N MS21141U0612 are
installed and no damage is found, no further
action is required. If any damage is found,
before further flight, repair using a method
approved in accordance with the procedures
specified in paragraph (g)(2) of this AD. If
any bolt with P/N AN173C11 is installed and
damage is found, replace the bolt and do all
related investigative and applicable
corrective actions before further flight.
(3) For Model 1125 Westwind Astra
airplanes (serial numbers 004, 011 through
072 inclusive, and 073 through 078
inclusive): Within 12 months after the
effective date of this AD, replace all P/N
AN173C11 bolts, and do all related
investigative and applicable corrective

actions before further flight, as detailed in
Part B of Gulfstream Alert Service Bulletin
100–55A–293, dated June 22, 2007.
Accomplishment of Part B of the alert service
bulletin constitutes terminating action for
paragraph (f)(1) of this AD. Israel Aircraft
Industries (Gulfstream) TR 15 may be deleted
and unlimited use of reverse thrust is
allowed per the Gulfstream Astra AFM.
Note 2: Reverse thrust limitations remain
in effect for Model Astra SPX and Gulfstream
100 airplanes.
FAA AD Differences
Note 3: This AD differs from the MCAI
and/or service information as follows:
Compliance Time: The compliance time
required by the MCAI or service information
for performing the AFM revision is
immediate on receipt of this AD; however, to
avoid inadvertently grounding airplanes, this
AD requires performing the AFM revision
within 30 days after the effective date of this
AD.
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, Transport Airplane
Directorate, FAA, has the authority to
approve AMOCs for this AD, if requested
using the procedures found in 14 CFR 39.19.
Send information to ATTN: Mike Borfitz,
Aerospace Engineer, International Branch,
ANM–116, FAA, Transport Airplane
Directorate, 1601 Lind Avenue, SW., Renton,
Washington 98057–3356; telephone (425)
227–2677; 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.

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 $33 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 $107,457, or $833 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

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:
2008-13-30 Gulfstream Aerospace LP (Formerly Israel Aircraft
Industries, Ltd.): Amendment 39-15593. Docket No. FAA-2008-0299;
Directorate Identifier 2007-NM-254-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective August
12, 2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Gulfstream Aerospace LP Model Astra SPX,
1125 Westwind Astra, and Gulfstream 100 airplanes; certificated in
any category; serial numbers 004 through 158.
Subject
(d) Air Transport Association (ATA) of America Code 55:
Stabilizers.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
Two of the fasteners used to attach the ``scissors'' to the
horizontal and the vertical stabilizers were found broken during
routine maintenance. The highest loads on the ``scissors'' occur
when using high reverse thrust. Therefore, the reverse thrust must
be limited to idle in order to keep the loads at a sufficiently low
level to preclude any structural problem. It was established that on
model 1125 Astra, alternate fasteners of inferior strength were
sometimes installed. When the originally specified fasteners are
installed, the limitations on reverse thrust used may be lifted. For
models Astra SPX and G100, however, the limitation remains in effect
till further revision of this AD.
Failure of the attachment fasteners could result in possible in-
flight loss of a horizontal or vertical stabilizer and consequent
loss of control of the airplane. Corrective actions include revising
the airplane flight manual (AFM); inspections for damage of the
bolts and replacing the bolt, if necessary; and doing related
investigative and other corrective actions (eddy current inspection
for bolt hole diameter and damage, contact Gulfstream for repair and
do repair).
Actions and Compliance
(f) Unless already done, do the following actions.
(1) Within 30 days after the effective date of this AD: Revise
the Limitations section of the AFM by incorporating the information
in the applicable Israel Aircraft Industries (Gulfstream) temporary
revisions (TR): Astra AFM TR 15; Astra SPX AFM TR 8; or Gulfstream
100 AFM TR 1; all dated June 14, 2007; into the Limitations section
of the Gulfstream Astra, Astra SPX, or Gulfstream 100 AFM, as
applicable. The TRs limit the normal use of reverse thrust to idle.
Note 1: The actions required by paragraph (f) of this AD may be
done by inserting a copy of Israel Aircraft Industries (Gulfstream)
Astra AFM TR 15; Astra SPX AFM TR 8; or Gulfstream 100 AFM TR 1; all
dated June 14, 2007; as applicable; into the Limitations section of
the Gulfstream Astra, Astra SPX, or Gulfstream 100 AFM, as
applicable. When the applicable TR has been included in the general
revisions of the applicable AFM, the general revisions may be
inserted in the AFM.
(2) For all airplanes: Within 25 flight hours or 30 days after
the effective date of this AD, whichever comes first, do the
inspections specified in paragraphs (f)(2)(i) and (f)(2)(ii) of this
AD in accordance with Part A of Gulfstream Alert Service Bulletin
100-55A-293, dated June 22, 2007.
(i) Visually inspect the attachment bolts and replace any
damaged bolt before further flight.
(ii) Perform a detailed visual inspection of fittings with part
number (P/N) 25W357222-501-51, and fillers with P/N 25W4011001-003,
and surrounding structure for damage. If blind bolts with P/N
MS21141U0612 are installed and no damage is found, no further action
is required. If any damage is found, before further flight, repair
using a method approved in accordance with the procedures specified
in paragraph (g)(2) of this AD. If any bolt with P/N AN173C11 is
installed and damage is found, replace the bolt and do all related
investigative and applicable corrective actions before further
flight.
(3) For Model 1125 Westwind Astra airplanes (serial numbers 004,
011 through 072 inclusive, and 073 through 078 inclusive): Within 12
months after the effective date of this AD, replace all P/N AN173C11
bolts, and do all related investigative and applicable corrective
[[Page 38900]]
actions before further flight, as detailed in Part B of Gulfstream
Alert Service Bulletin 100-55A-293, dated June 22, 2007.
Accomplishment of Part B of the alert service bulletin constitutes
terminating action for paragraph (f)(1) of this AD. Israel Aircraft
Industries (Gulfstream) TR 15 may be deleted and unlimited use of
reverse thrust is allowed per the Gulfstream Astra AFM.
Note 2: Reverse thrust limitations remain in effect for Model
Astra SPX and Gulfstream 100 airplanes.
FAA AD Differences
Note 3: This AD differs from the MCAI and/or service information
as follows:
Compliance Time: The compliance time required by the MCAI or
service information for performing the AFM revision is immediate on
receipt of this AD; however, to avoid inadvertently grounding
airplanes, this AD requires performing the AFM revision within 30
days after the effective date of this AD.
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, Transport Airplane Directorate, FAA,
has the authority to approve AMOCs for this AD, if requested using
the procedures found in 14 CFR 39.19. Send information to ATTN: Mike
Borfitz, Aerospace Engineer, International Branch, ANM-116, FAA,
Transport Airplane Directorate, 1601 Lind Avenue, SW., Renton,
Washington 98057-3356; telephone (425) 227-2677; 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.
