ACTION: Final rule; request for
comments.
AGENCY:
SUMMARY: The FAA is adopting a new
airworthiness directive (AD) for certain
Gulfstream Model GIV–X, GV, and GV–
SP series airplanes. This AD requires
revising the airplane flight manuals
(AFMs) of those airplanes, and doing
repetitive functional checks of the
forward water drain/supply valves and
applicable corrective actions. This AD
also provides for optional terminating
action for the repetitive functional
checks. This AD results from reports of
failed forward water drain/supply
valves on numerous airplanes, and
reports of ice striking the wing-to-body
fairings and engine nose cowls of
several airplanes. We are issuing this
AD to prevent leakage from failed water
drain/supply valves allowing the buildup of ice on the airplane, which could
separate and strike the airplane
structure aft of the failed valves; become
ingested by a propulsion engine; or
become a hazard to persons or property
on the ground.
DATES: This AD becomes effective July
5, 2007.
The Director of the Federal Register
approved the incorporation by reference
of certain publications listed in the AD
as of July 5, 2007.
We must receive comments on this
AD by August 20, 2007.

SUPPLEMENTARY INFORMATION:
Discussion
We have received a report of 18
instances of failed forward water drain/
supply valves on Gulfstream Model
GIV–X, GV, and GV–SP series airplanes.
Investigation by the airplane
manufacturer revealed that the water
drain/supply valves can be damaged by
attempted operation when they are
frozen. We also received a report of
seven instances of ice striking the wingto-body fairings and engine nose cowls
of several airplanes. Leakage from failed
water drain/supply valves can allow the
build-up of ice on the airplane, which
could separate and strike the airplane
structure aft of the failed valves; become
ingested by a propulsion engine; or
become a hazard to persons or property
on the ground.
Relevant Service Information
We have reviewed the Gulfstream
airplane flight manual (AFM)
supplements and alert customer
bulletins, including the Joint Aviation
Authority (JAA) Gulfstream AFM
revisions. We have identified these
documents in the following tables.
The Gulfstream AFM supplements
describe procedures for revising the
Normal Procedures section of the AFMs
of the affected airplanes to specify a
functional check of forward water drain/
supply valves, and corrective actions if
necessary. Corrective actions include
purging, deactivating, and securing the
galley and lavatory sinks, or the entire
water system, as applicable, and
placarding those systems ‘‘Inoperative’’
or ‘‘Do Not Use.’’ The AFM supplements
are identified as follows:

FAA’s Determination and Requirements
of This AD
The unsafe condition described
previously is likely to exist or develop
on other airplanes of the same type
design. For this reason, we are issuing
this AD to prevent leakage from failed
water drain/supply valves allowing the
build-up of ice on the airplane, which
could separate and strike the airplane
structure aft of the failed valves; become
ingested by a propulsion engine; or
become a hazard to persons or property
on the ground. This AD requires
accomplishing the actions specified in
the service information described
previously, except as discussed under
‘‘Differences Between the AD and
Service Information.’’
jlentini on PROD1PC65 with RULES
Differences Between the AD and
Service Information
The alert customer bulletins do not
describe procedures to be followed if
the part number of a water drain/supply
valve is missing or cannot be
determined. However, this AD requires
replacing any such valve with a new,
VerDate Aug<31>2005
17:14 Jun 19, 2007
Jkt 211001
improved valve having P/N 4E4491–1 or
P/N 4E4493–1, as applicable.
Although the Accomplishment
Instructions of the referenced alert
customer bulletins describe procedures
for submitting reports of compliance
with the service bulletin, this AD does
not require those actions.
Interim Action
We consider this AD interim action.
We are currently considering requiring
the optional terminating action
(replacing the water drain/supply
valves) provided in this AD, which will
terminate the required repetitive
functional checks. However, the
planned compliance time for the
terminating action would allow enough
time to provide notice and opportunity
for prior public comment on the merits
of the valve replacement.
Clarification of Terminology
This AD provides procedures for
repetitive functional checks for proper
operation of the forward water drain/
supply valves, and corrective actions if
necessary. We have determined that
these functional checks and corrective

actions may be properly performed by
the cockpit flightcrew because the
checks and actions do not require tools,
precision measuring equipment,
training, or pilot logbook endorsements,
or the use of or reference to technical
data.
FAA’s Determination of the Effective
Date
Since an unsafe condition exists that
requires the immediate adoption of this
AD, we have found that notice and
opportunity for public comment before
issuing this AD are impracticable, and
that good cause exists to make this AD
effective in less than 30 days.
Comments Invited
This AD is a final rule that involves
requirements that affect flight safety and
was not preceded by notice and an
opportunity for public comment;
however, we invite you to submit any
relevant written data, views, or
arguments regarding this AD. Send your
comments to an address listed in the
ADDRESSES section. Include ‘‘Docket No.

your comments. We specifically invite
comments on the overall regulatory,
economic, environmental, and energy
aspects of the AD that might suggest a
need to modify it.
We will post all comments we
receive, without change, to https://
dms.dot.gov, including any personal
information you provide. We will also
post a report summarizing each
substantive verbal contact with FAA
personnel concerning this AD. Using the
search function of that Web site, anyone
can find and read the comments in any
of our dockets, including the name of
the individual who sent the comment
(or signed the comment on behalf of an
association, business, labor union, etc.).
You may review the DOT’s complete
Privacy Act Statement in the Federal
Register published on April 11, 2000
(65 FR 19477–78), or you may visit
https://dms.dot.gov.
Examining the Docket
You may examine the AD docket on
the Internet at https://dms.dot.gov, or in
person at the Docket Management
Facility office between 9 a.m. and 5
p.m., Monday through Friday, except
Federal holidays. The Docket
Management Facility office (telephone
(800) 647–5227) is located on the plaza
level of the Nassif Building at the DOT
street address stated in the ADDRESSES
section. Comments will be available in
the AD docket shortly after the Docket
Management System receives them.
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 have 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 that the 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 AD and placed it in the AD docket.
See the ADDRESSES section for a location
to examine the regulatory evaluation.

Discussion
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would
33871
apply to all McDonnell Douglas Model
DC–8–62, DC–8–62F, DC–8–63, DC–8–
63F, DC–8–72, DC–8–72F, and DC–8–
73F airplanes. That NPRM was
published in the Federal Register on
April 4, 2007 (72 FR 16287). That NPRM
proposed to require deactivating certain
components (the sump heater, scavenge
valve, and scavenge pump) of the center
wing fuel tank.
Comments
We provided the public the
opportunity to participate in the
development of this AD. We received no
comments on the NPRM or on the
determination of the cost to the public.
Clarification of Alternative Method of
Compliance (AMOC) Paragraph
We have revised this action to clarify
the appropriate procedure for notifying
the principal inspector before using any
approved AMOC on any airplane to
which the AMOC applies.
Conclusion
We have carefully reviewed the
available data and determined that air
safety and the public interest require
adopting the AD with the change
described previously. We have
determined that this change will neither
increase the economic burden on any
operator nor increase the scope of the
AD.
Costs of Compliance
There are about 119 airplanes of the
affected design in the worldwide fleet.
The following table provides the
estimated costs for U.S. operators to
comply with this AD.

Airworthiness Directives; Gulfstream Model GIV-X, GV, and GV-SP
Series Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain Gulfstream Model GIV-X, GV, and GV-SP series airplanes. This AD
requires revising the airplane flight manuals (AFMs) of those
airplanes, and doing repetitive functional checks of the forward water
drain/supply valves and applicable corrective actions. This AD also
provides for optional terminating action for the repetitive functional
checks. This AD results from reports of failed forward water drain/
supply valves on numerous airplanes, and reports of ice striking the
wing-to-body fairings and engine nose cowls of several airplanes. We
are issuing this AD to prevent leakage from failed water drain/supply
valves allowing the build-up of ice on the airplane, which could
separate and strike the airplane structure aft of the failed valves;
become ingested by a propulsion engine; or become a hazard to persons
or property on the ground.
DATES: This AD becomes effective July 5, 2007.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of July 5, 2007.
We must receive comments on this AD by August 20, 2007.

SUPPLEMENTARY INFORMATION:
Discussion
We have received a report of 18 instances of failed forward water
drain/supply valves on Gulfstream Model GIV-X, GV, and GV-SP series
airplanes. Investigation by the airplane manufacturer revealed that the
water drain/supply valves can be damaged by attempted operation when
they are frozen. We also received a report of seven instances of ice
striking the wing-to-body fairings and engine nose cowls of several
airplanes. Leakage from failed water drain/supply valves can allow the
build-up of ice on the airplane, which could separate and strike the
airplane structure aft of the failed valves; become ingested by a
propulsion engine; or become a hazard to persons or property on the
ground.
Relevant Service Information
We have reviewed the Gulfstream airplane flight manual (AFM)
supplements and alert customer bulletins, including the Joint Aviation
Authority (JAA) Gulfstream AFM revisions. We have identified these
documents in the following tables.
The Gulfstream AFM supplements describe procedures for revising the
Normal Procedures section of the AFMs of the affected airplanes to
specify a functional check of forward water drain/supply valves, and
corrective actions if necessary. Corrective actions include purging,
deactivating, and securing the galley and lavatory sinks, or the entire
water system, as applicable, and placarding those systems
``Inoperative'' or ``Do Not Use.'' The AFM supplements are identified
as follows:

FAA's Determination and Requirements of This AD
The unsafe condition described previously is likely to exist or
develop on other airplanes of the same type design. For this reason, we
are issuing this AD to prevent leakage from failed water drain/supply
valves allowing the build-up of ice on the airplane, which could
separate and strike the airplane structure aft of the failed valves;
become ingested by a propulsion engine; or become a hazard to persons
or property on the ground. This AD requires accomplishing the actions
specified in the service information described previously, except as
discussed under ``Differences Between the AD and Service Information.''
Differences Between the AD and Service Information
The alert customer bulletins do not describe procedures to be
followed if the part number of a water drain/supply valve is missing or
cannot be determined. However, this AD requires replacing any such
valve with a new, improved valve having P/N 4E4491-1 or P/N 4E4493-1,
as applicable.
Although the Accomplishment Instructions of the referenced alert
customer bulletins describe procedures for submitting reports of
compliance with the service bulletin, this AD does not require those
actions.
Interim Action
We consider this AD interim action. We are currently considering
requiring the optional terminating action (replacing the water drain/
supply valves) provided in this AD, which will terminate the required
repetitive functional checks. However, the planned compliance time for
the terminating action would allow enough time to provide notice and
opportunity for prior public comment on the merits of the valve
replacement.
Clarification of Terminology
This AD provides procedures for repetitive functional checks for
proper operation of the forward water drain/supply valves, and
corrective actions if necessary. We have determined that these
functional checks and corrective actions may be properly performed by
the cockpit flightcrew because the checks and actions do not require
tools, precision measuring equipment, training, or pilot logbook
endorsements, or the use of or reference to technical data.
FAA's Determination of the Effective Date
Since an unsafe condition exists that requires the immediate
adoption of this AD, we have found that notice and opportunity for
public comment before issuing this AD are impracticable, and that good
cause exists to make this AD effective in less than 30 days.
Comments Invited
This AD is a final rule that involves requirements that affect
flight safety and was not preceded by notice and an opportunity for
public comment; however, we invite you to submit any relevant written
data, views, or arguments regarding this AD. Send your comments to an
address listed in the ADDRESSES section. Include ``Docket No. FAA-2007-
28373; Directorate Identifier 2007-NM-110-AD'' at the beginning of
[[Page 33869]]
your comments. We specifically invite comments on the overall
regulatory, economic, environmental, and energy aspects of the AD that
might suggest a need to modify it.
We will post all comments we receive, without change, to https://
dms.dot.gov, including any personal information you provide. We will
also post a report summarizing each substantive verbal contact with FAA
personnel concerning this AD. Using the search function of that Web
site, anyone can find and read the comments in any of our dockets,
including the name of the individual who sent the comment (or signed
the comment on behalf of an association, business, labor union, etc.).
You may review the DOT's complete Privacy Act Statement in the Federal
Register published on April 11, 2000 (65 FR 19477-78), or you may visit
https://dms.dot.gov.
Examining the Docket
You may examine the AD docket on the Internet at https://
dms.dot.gov, or in person at the Docket Management Facility office
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The Docket Management Facility office (telephone (800) 647-
5227) is located on the plaza level of the Nassif Building at the DOT
street address stated in the ADDRESSES section. Comments will be
available in the AD docket shortly after the Docket Management System
receives them.
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 have 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 that the 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 AD and placed it in the AD docket. See the ADDRESSES
section for a location to examine the regulatory evaluation.
