that PSE inspection. The compliance time for
accomplishing this inspection must be
measured from the last inspection done by
the previous operator. After each inspection
has been done once, each subsequent
inspection must be done in accordance with
the new operator’s schedule and inspection
method.
(2) For airplanes that have not been
inspected in accordance with this AD: The
inspection of each PSE required by this AD
must be done either before adding the
airplane to the air carrier’s operations
specification, or in accordance with a
schedule and an inspection method approved
by the Manager, Los Angeles ACO. After each
inspection has been done once, each
subsequent inspection must be done in
accordance with the new operator’s schedule.
DEPARTMENT OF TRANSPORTATION
Acceptable for Compliance
SUMMARY: We propose to adopt a new
airworthiness directive (AD) for the
products listed above. This proposed
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:
(n) McDonnell Douglas Report No. MDC
91K0262, ‘‘DC–8 Aging Aircraft Repair
Assessment Program Document,’’ Revision 1,
dated October 2000, provides inspection/
replacement programs for certain repairs to
the fuselage pressure shell. Accomplishing
these repairs and inspection/replacement
programs before the effective date of this AD
is considered acceptable for compliance with
the requirements of paragraphs (g) and (l) of
this AD for repairs subject to that document.
Alternative Methods of Compliance
(AMOCs)
rmajette on PROD1PC64 with PROPOSALS
(o)(1) The Manager, Los Angeles ACO, has
the authority to approve AMOCs for this AD,
if requested in accordance with the
procedures found in 14 CFR 39.19.
(2) To request a different method of
compliance or a different compliance time
for this AD, follow the procedures in 14 CFR
39.19. 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.
(3) An AMOC that provides an acceptable
level of safety may be used for any repair
required by this AD, if it is approved by an
Authorized Representative for the Boeing
Commercial Airplanes Delegation Option
Authorization Organization who has been
authorized by the Manager, Los Angeles
ACO, to make those findings. For a repair
method to be approved, the repair must meet
the certification basis of the airplane and 14
CFR 25.571, Amendment 45, and the
approval must specifically refer to this AD.
(4) AMOCs approved previously in
accordance with AD 93–01–15 are approved
as AMOCs for the corresponding provisions
of this AD.

Discussion
The Civil Aviation Authority of Israel
(CAAI), which is the aviation authority
for Israel, has issued Israeli
Airworthiness Directive 24–07–10–11,
dated October 31, 2007 (referred to after
this as ‘‘the MCAI’’), to correct an unsafe
condition for the specified products.
The MCAI states:
Possible chafing between [the] electrical
feeder cable connected to contactor 123P/2
and ground point 803GND, installed within
the left DC power box, discovered during
routine receiving inspection. This condition
may exist on boxes installed on in-service
aircraft. If this chafing condition is left
unattended, an electrical short may develop,
leading to disconnection of the battery and
battery bus from the electrical system of the
aircraft, [which could result in] overheating,
arcing, smoke and fire.
The corrective action includes
inspecting for chafing and arcing
damage of the feeder cable terminal lug
and ground point, contacting Gulfstream
for repair if any damage is found, and
E:\FR\FM\05FEP1.SGM

repairing, and installing new heatshrink tubing if the tubing is missing or
damaged, and repositioning the feeder
cable. You may obtain further
information by examining the MCAI in
the AD docket.
Based on these figures, we estimate the
cost of the proposed AD on U.S.
operators to be $6,240, or $240 per
product.
Relevant Service Information
Gulfstream has issued Alert Service
Bulletin 150–24A–046, dated October
31, 2007. The actions described in this
service information are intended to
correct the unsafe condition identified
in the MCAI.
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.
FAA’s Determination and Requirements
of This Proposed AD
This product has been approved by
the aviation authority of another
country, and is approved for operation
in the United States. Pursuant to our
bilateral agreement with the State of
Design Authority, we have been notified
of the unsafe condition described in the
MCAI and service information
referenced above. We are proposing this
AD because we evaluated all pertinent
information and determined an unsafe
condition exists and is likely to exist or
develop on other products of the same
type design.
rmajette on PROD1PC64 with PROPOSALS
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 proposed
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
proposed AD.
Costs of Compliance
Based on the service information, we
estimate that this proposed AD would
affect about 26 products of U.S. registry.
We also estimate that it would take
about 3 work-hours per product to
comply with the basic requirements of
this proposed AD. The average labor
rate is $80 per work-hour. Required
parts would cost about $0 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 costs.
As we do not control warranty coverage
for affected parties, some parties may
incur costs higher than estimated here.

continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
§ 39.13
[Amended]
2. The FAA amends § 39.13 by adding
the following new AD:
Gulfstream Aerospace LP (Formerly Israel
Aircraft Industries, Ltd.): Docket No.
FAA–2008–0120; Directorate Identifier
2007–NM–327–AD.
Comments Due Date
(a) We must receive comments by March 6,
2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Gulfstream Model
Gulfstream G150 airplanes, certificated in
any category, serial numbers 201 through 239
inclusive.
Subject
(d) Air Transport Association (ATA) of
America Code 24: Electrical power.
Regulatory Findings
Reason
We determined that this proposed AD
would not have federalism implications
under Executive Order 13132. This
proposed AD would 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 proposed regulation:
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 proposed AD and placed it in the
AD docket.
(e) The mandatory continuing
airworthiness information (MCAI) states:
‘‘Possible chafing between [the] electrical
feeder cable connected to contactor 123P/2
and ground point 803GND, installed within
the left DC power box, discovered during
routine receiving inspection. This condition
may exist on boxes installed on in-service
aircraft. If this chafing condition is left
unattended, an electrical short may develop,
leading to disconnection of the battery and
battery bus from the electrical system of the
aircraft, [which could result in] overheating,
arcing, smoke and fire.’’
The corrective action includes inspecting
for chafing and arcing damage of the feeder
cable terminal lug and ground point,
contacting Gulfstream for repair if any
damage is found, and repairing, and
installing new heat-shrink tubing if the
tubing is missing or damaged, and
repositioning the feeder cable.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation
safety, Safety.
The Proposed Amendment
Accordingly, under the authority
delegated to me by the Administrator,
the FAA proposes to amend 14 CFR part
39 as follows:

Discussion
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Community, has issued EASA
Airworthiness Directive 2007–0229,
dated August 15, 2007 (referred to after
this as ‘‘the MCAI’’), to correct an unsafe
condition for the specified products.
The MCAI states:
In 1997, Fokker introduced a new type of
Peri-seal (SBF 100–30–022). The old type
was known to be subject to deterioration,
which, in combination with improper
installation, can cause leakage of hot wing
anti-icing air from the Peri-seal housing. This
results in an uncontrolled flow of highpressure hot air to enter the forward (antiicing) plenum chamber of the wing leading
edge, potentially damaging the anti-icing
barrier webs. Subsequently, the wing
auxiliary spar can also be damaged by highpressure hot air. Analysis at the time showed
that any resulting damage (known to occur at
inboard positions only) would not affect the
wing load capability. For this reason, the
modification was not classified as
MANDATORY and no AD action was
warranted. However, through a recent
occurrence, it was discovered that
deterioration of the Peri-seals enables the
piccolo tubes to vibrate, resulting in a broken
piccolo tube. In this case, the location of the
failure was more outboard than previous
occurrences. This condition, if not corrected,
may cause heat damage to the front spar that
potentially affects the wing’s load capability.
Since an unsafe condition was identified,
likely to exist or develop on an aircraft of this
type design, CAA (Civil Aviation Authority)
Netherlands issued AD NL–2006–011 to
require inspection of the Piccolo Tubes and
the surrounding structure to establish correct
installation, as well as the replacement of the
460-series Peri-seals by the improved 600series, which have a higher temperature
limit.
Since the issuance of that AD, Fokker has
developed a modification, published as

Discussion
The Civil Aviation Authority of Israel (CAAI), which is the
aviation authority for Israel, has issued Israeli Airworthiness
Directive 24-07-10-11, dated October 31, 2007 (referred to after this
as ``the MCAI''), to correct an unsafe condition for the specified
products. The MCAI states:
Possible chafing between [the] electrical feeder cable connected
to contactor 123P/2 and ground point 803GND, installed within the
left DC power box, discovered during routine receiving inspection.
This condition may exist on boxes installed on in-service aircraft.
If this chafing condition is left unattended, an electrical short
may develop, leading to disconnection of the battery and battery bus
from the electrical system of the aircraft, [which could result in]
overheating, arcing, smoke and fire.
The corrective action includes inspecting for chafing and arcing damage
of the feeder cable terminal lug and ground point, contacting
Gulfstream for repair if any damage is found, and
[[Page 6628]]
repairing, and installing new heat-shrink tubing if the tubing is
missing or damaged, and repositioning the feeder cable. You may obtain
further information by examining the MCAI in the AD docket.
Relevant Service Information
Gulfstream has issued Alert Service Bulletin 150-24A-046, dated
October 31, 2007. The actions described in this service information are
intended to correct the unsafe condition identified in the MCAI.
FAA's Determination and Requirements of This Proposed AD
This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to our bilateral agreement with the State of Design Authority, we have
been notified of the unsafe condition described in the MCAI and service
information referenced above. We are proposing this AD because we
evaluated all pertinent information and determined an unsafe condition
exists and is likely to exist or develop on other products of the same
type design.
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 proposed 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 proposed AD.
Costs of Compliance
Based on the service information, we estimate that this proposed AD
would affect about 26 products of U.S. registry. We also estimate that
it would take about 3 work-hours per product to comply with the basic
requirements of this proposed AD. The average labor rate is $80 per
work-hour. Required parts would cost about $0 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 costs.
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 the proposed AD on U.S. operators to
be $6,240, or $240 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 proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 proposed
regulation:
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 proposed AD and placed it in the AD docket.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Safety.
The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
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]
2. The FAA amends Sec. 39.13 by adding the following new AD:
Gulfstream Aerospace LP (Formerly Israel Aircraft Industries, Ltd.):
Docket No. FAA-2008-0120; Directorate Identifier 2007-NM-327-AD.
Comments Due Date
(a) We must receive comments by March 6, 2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Gulfstream Model Gulfstream G150
airplanes, certificated in any category, serial numbers 201 through
239 inclusive.
Subject
(d) Air Transport Association (ATA) of America Code 24:
Electrical power.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
``Possible chafing between [the] electrical feeder cable
connected to contactor 123P/2 and ground point 803GND, installed
within the left DC power box, discovered during routine receiving
inspection. This condition may exist on boxes installed on in-
service aircraft. If this chafing condition is left unattended, an
electrical short may develop, leading to disconnection of the
battery and battery bus from the electrical system of the aircraft,
[which could result in] overheating, arcing, smoke and fire.''
The corrective action includes inspecting for chafing and arcing
damage of the feeder cable terminal lug and ground point, contacting
Gulfstream for repair if any damage is found, and repairing, and
installing new heat-shrink tubing if the tubing is missing or
damaged, and repositioning the feeder cable.
Actions and Compliance
(f) Unless already done, do the following actions. Within 50
flight hours or 30 days after the effective date of this AD,
whichever occurs first, inspect the feeder cable, terminal lug 123P/
2, and ground point 803GND for chafing and arcing damage, reposition
the feeder cable to maintain an adequate gap, and do all applicable
corrective actions. Do the actions in accordance with Gulfstream
Alert Service Bulletin 150-24A-046, dated October 31, 2007. Do all
applicable corrective actions before further flight.
FAA AD Differences
Note: This AD differs from the MCAI and/or service information
as follows: No differences.

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
