Federal Register / Vol. 73, No. 78 / Tuesday, April 22, 2008 / Proposed Rules
This action would revise the reporting
and recordkeeping requirements
specified in the order’s administrative
rules and regulations for all California
raisin handlers. These requirements
were approved under OMB No. 0581–
0178, Vegetable and Specialty Crops. No
change to this approval is warranted as
a result of this action. This action would
bring the regulations in line with
current industry practices. Data
regarding off-grade raisins has been
computerized since the early 1990’s. It
is no longer necessary for handlers to
advise the inspection service nor the
Committee in writing when they
perform certain functions regarding offgrade raisins. Handlers provide such
notification verbally or by other means
of communication, including e-mail.
The time it takes to provide such
information is minimal. Likewise, it is
no longer necessary for handlers to
submit reports to the Committee
regarding transfers of off-grade for
reconditioning or other failing raisins.
Handlers submit other weekly and
monthly reports to the Committee
regarding off-grade and other failing
raisins that allows Committee staff to
track such raisins.
As with all Federal marketing order
programs, reports and forms are
periodically reviewed to reduce
information requirements and
duplication by industry and public
sector agencies.
AMS is committed to complying with
the E-Government Act, to promote the
use of the Internet and other
information technologies to provide
increased opportunities for citizen
access to Government information and
services, and for other purposes.
USDA has not identified any relevant
Federal rules that duplicate, overlap or
conflict with this proposed rule.
In addition, the Committee’s July 11,
2007, meeting and the Administrative
Issues Subcommittee meeting held
earlier that day were widely publicized
throughout the raisin industry. All
interested persons were invited to
attend the meetings and participate in
Committee deliberations on all issues.
Like all Committee meetings, both were
public meetings and all entities, both
large and small, were able to express
views on this issue. Finally, interested
persons are invited to submit comments
on this proposed rule, including the
regulatory and informational impacts of
this action on small businesses.

with fruit, vegetable, and specialty crop
marketing agreements and orders may

A 30-day comment period is provided
to allow interested persons to respond
to this proposal. Thirty days is deemed
appropriate because this action removes
requirements upon handlers that are no
longer necessary. All written comments
timely received will be considered
before a final determination is made on
this matter.

ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
SUMMARY: We propose to adopt a new
airworthiness directive (AD) for the
specified Eurocopter France (ECF)
model helicopters. 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 aviation authority of
France, with which we have a bilateral
agreement, states in the MCAI:

21554
Federal Register / Vol. 73, No. 78 / Tuesday, April 22, 2008 / Proposed Rules
ebenthall on PRODPC60 with PROPOSALS
This Airworthiness Directive (AD) is
issued following two cases of LH hydraulic
power system loss on two AS332 helicopters.
In both cases, the pilot received the ‘‘low
level’’ hydraulic failure alarm. The
investigations conducted on the two
helicopters revealed a hydraulic fluid leak
from the hydraulic pump casing.
In both cases, incorrect position of the liner
of the compensating piston had caused the
seals to deteriorate. This incorrect
positioning of the liner is due to noncompliant application of the repair process
by a repair station.
Deterioration of hydraulic pumps causes:
—The loss of the RH and LH hydraulic power
systems in the event of a substantial
hydraulic fluid leak from both hydraulic
pumps during a given flight.
—The loss of the hydraulic system
concerned, in the event of a substantial
hydraulic fluid leak from only one pump.
The proposed AD would require actions
that are intended to address this unsafe
condition.
DATES: We must receive comments on
this proposed AD by May 22, 2008.
ADDRESSES: You may send comments by
any of the following methods:
• Federal eRulemaking Portal: Go to

Discussion
The Direction Generale de L’Aviation
Civile (DGAC), the aviation authority for
France, has issued French
Airworthiness Directive No. F–2007–
010, dated September 12, 2007 (referred
to after this as ‘‘the MCAI’’), to correct
an unsafe condition for this Frenchcertificated product. The MCAI states:
This Airworthiness Directive (AD) is
issued following two cases of LH hydraulic
power system loss on two AS332 helicopters.
In both cases, the pilot received the ‘‘low
level’’ hydraulic failure alarm. The
investigations conducted on the two
helicopters revealed a hydraulic fluid leak
from the hydraulic pump casing.
In both cases, incorrect position of the liner

hydraulic fluid leak from both hydraulic
pumps during a given flight.
—The loss of the hydraulic system
concerned, in the event of a substantial
hydraulic fluid leak from only one pump.
You may obtain further information
by examining the MCAI and service
information in the AD docket.
Relevant Service Information
Eurocopter France has issued Alert
Service Bulletin No. 01.00.73, dated
August 23, 2007 (ASB). The actions
described in the MCAI are intended to
correct the same unsafe condition as
that identified in the ASB.
FAA’s Determination and Proposed
Requirements
This product has been approved by
the aviation authority of France and is
approved for operation in the United
States. Pursuant to our bilateral
agreement with this State of Design
Authority, we have been notified of the
unsafe condition described in the MCAI
and service information. 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
We have reviewed the MCAI and
related service information and, in
general, agree with their substance.
However, we have made the following
changes:
• We do not require the operator to
return the hydraulic pump to the
manufacturer nor any action on noninstalled hydraulic pumps.
• We changed ‘‘flying hours’’ to
‘‘hours time-in-service.’’
In making these changes, we do not
intend to differ substantively from the
information provided in the MCAI.
These differences are highlighted in the
‘‘Differences Between the FAA and the
MCAI’’ section in the proposed AD.
Costs of Compliance
We estimate that this proposed AD
would affect 4 helicopters of U.S.
registry. We also estimate that it would
take 2.5 work-hours to inspect and
replace one hydraulic pump. The
average labor rate is $80 per work-hour.
Each pump would cost about $26,000
and require two hydraulic pumps per
helicopter. Based on these figures, we
estimate the cost of the proposed AD on
U.S. operators to be $209,600 to replace
all the hydraulic pumps on the U.S.
fleet.
E:\FR\FM\22APP1.SGM
22APP1
Federal Register / Vol. 73, No. 78 / Tuesday, April 22, 2008 / Proposed Rules
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 an economic evaluation
of the estimated costs to comply with
this proposed AD and placed it in the
AD docket.

Comments Due Date
(a) We must receive comments by May 22,
2008.
Other Affected ADs
(b) None.
Applicability
(c) This AD applies to Models AS332C, L,
L1, and L2 helicopters, with a hydraulic
pump made by Messier-Bugatti, part number
C24160–X, C24160–XXX, C241600XX,
C241600XX–X, and C241600XX–XXX, with a
serial number without the suffix letter ‘‘V’’,
listed in paragraph 1.A.1., of Eurocopter
France Emergency Alert Service Bulletin
01.00.73, dated August 23, 2007 (ASB)
installed, certificated in any category.
Note: The letter ‘‘V’’ is a suffix marked
after the serial number on the pump’s
identification plate to signify that the pump
has been determined to conform to the
approved design data.
Reason
(d) The mandatory continuing
airworthiness information (MCAI) states:
This Airworthiness Directive (AD) is
issued following two cases of LH hydraulic
power system loss on two AS332 helicopters.
In both cases, the pilot received the ‘‘low
level’’ hydraulic failure alarm. The
investigations conducted on the two
helicopters revealed a hydraulic fluid leak
from the hydraulic pump casing.
In both cases, incorrect position of the liner
of the compensating piston had caused the
seals to deteriorate. This incorrect
positioning of the liner is due to noncompliant application of the repair process
by a repair station.
Deterioration of hydraulic pumps causes:
—The loss of the RH and LH hydraulic power
systems in the event of a substantial
hydraulic fluid leak from both hydraulic
pumps during a given flight.
—The loss of the hydraulic system
concerned, in the event of a substantial
hydraulic fluid leak from only one pump.
Actions and Compliance
(e) Unless already done, do the following
actions:
(1) Within 15 hours time-in-service (TIS),
determine the part number and serial number
of the installed hydraulic pumps. If the serial

further flight, replace at least one of the
pumps with an airworthy pump with a serial
number other than one listed in paragraph
1.A.1. of the ASB or one with a serial number
containing the letter ‘‘V’’. Replace the pump
by following the Accomplishment
Instructions, paragraph 2.B. of the ASB,
except this AD does not require you to return
the hydraulic pump to the manufacturer.
(2) Within the next 12 months, replace all
remaining hydraulic pumps having a serial

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the
specified Eurocopter France (ECF) model helicopters. 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 aviation
authority of France, with which we have a bilateral agreement, states
in the MCAI:
[[Page 21554]]
This Airworthiness Directive (AD) is issued following two cases
of LH hydraulic power system loss on two AS332 helicopters. In both
cases, the pilot received the ``low level'' hydraulic failure alarm.
The investigations conducted on the two helicopters revealed a
hydraulic fluid leak from the hydraulic pump casing.
In both cases, incorrect position of the liner of the
compensating piston had caused the seals to deteriorate. This
incorrect positioning of the liner is due to non-compliant
application of the repair process by a repair station.
Deterioration of hydraulic pumps causes:
--The loss of the RH and LH hydraulic power systems in the event of
a substantial hydraulic fluid leak from both hydraulic pumps during
a given flight.
--The loss of the hydraulic system concerned, in the event of a
substantial hydraulic fluid leak from only one pump.
The proposed AD would require actions that are intended to address this
unsafe condition.

We changed ``flying hours'' to ``hours time-in-service.''
In making these changes, we do not intend to differ substantively
from the information provided in the MCAI. These differences are
highlighted in the ``Differences Between the FAA and the MCAI'' section
in the proposed AD.
Costs of Compliance
We estimate that this proposed AD would affect 4 helicopters of
U.S. registry. We also estimate that it would take 2.5 work-hours to
inspect and replace one hydraulic pump. The average labor rate is $80
per work-hour. Each pump would cost about $26,000 and require two
hydraulic pumps per helicopter. Based on these figures, we estimate the
cost of the proposed AD on U.S. operators to be $209,600 to replace all
the hydraulic pumps on the U.S. fleet.

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 an economic 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:
Eurocopter France: Docket No. FAA-2008-0430; Directorate Identifier
2007-SW-42-AD.
Comments Due Date
(a) We must receive comments by May 22, 2008.
Other Affected ADs
(b) None.
Applicability
(c) This AD applies to Models AS332C, L, L1, and L2 helicopters,
with a hydraulic pump made by Messier-Bugatti, part number C24160-X,
C24160-XXX, C241600XX, C241600XX-X, and C241600XX-XXX, with a serial
number without the suffix letter ``V'', listed in paragraph 1.A.1.,
of Eurocopter France Emergency Alert Service Bulletin 01.00.73,
dated August 23, 2007 (ASB) installed, certificated in any category.
Note: The letter ``V'' is a suffix marked after the serial
number on the pump's identification plate to signify that the pump
has been determined to conform to the approved design data.
Reason
(d) The mandatory continuing airworthiness information (MCAI)
states:
This Airworthiness Directive (AD) is issued following two cases
of LH hydraulic power system loss on two AS332 helicopters. In both
cases, the pilot received the ``low level'' hydraulic failure alarm.
The investigations conducted on the two helicopters revealed a
hydraulic fluid leak from the hydraulic pump casing.
In both cases, incorrect position of the liner of the
compensating piston had caused the seals to deteriorate. This
incorrect positioning of the liner is due to non-compliant
application of the repair process by a repair station.
Deterioration of hydraulic pumps causes:
--The loss of the RH and LH hydraulic power systems in the event of
a substantial hydraulic fluid leak from both hydraulic pumps during
a given flight.
--The loss of the hydraulic system concerned, in the event of a
substantial hydraulic fluid leak from only one pump.
Actions and Compliance
(e) Unless already done, do the following actions:
(1) Within 15 hours time-in-service (TIS), determine the part
number and serial number of the installed hydraulic pumps. If the
serial numbers of both the hydraulic pumps are listed in paragraph
1.A.1. of the ASB, before further flight, replace at least one of
the pumps with an airworthy pump with a serial number other than one
listed in paragraph 1.A.1. of the ASB or one with a serial number
containing the letter ``V''. Replace the pump by following the
Accomplishment Instructions, paragraph 2.B. of the ASB, except this
AD does not require you to return the hydraulic pump to the
manufacturer.
(2) Within the next 12 months, replace all remaining hydraulic
pumps having a serial number listed in paragraph 1.A.1. of the ASB
by following the Accomplishment Instructions, paragraph 2.B. of the
ASB, except this AD does not require you to return the hydraulic
pump to the manufacturer.
Differences Between the FAA AD and the MCAI
(f) We do not require the operator to return the hydraulic pump
to the manufacturer nor do we require any action on non-installed
hydraulic pumps. Also, we changed ``flying hours'' to ``hours time-
in-service.''
Subject
(g) Air Transport Association of America (ATA) Code: 2913
Hydraulic Pump.
