tend to effectuate the declared policy of
the Act.
Pursuant to 5 U.S.C. 553, it is also
found and determined upon good cause
that it is impracticable, unnecessary,
and contrary to the public interest to
give preliminary notice prior to putting
this rule into effect and that good cause
exist for not postponing the effective
date of this rule until 30 days after
publication in the Federal Register
because: (1) Any changes resulting from
this rule should be effective as soon as
practicable because the Washington
potato shipping season began in July; (2)
the Committee unanimously
recommended these changes at a public
meeting and all interested parties had
an opportunity to provide input; (3)
handlers are aware of this action and
want to take advantage of this relaxation
as soon as possible; and (4) this rule
provides a 60-day comment period and
any comments received will be
considered prior to finalization of this
rule.

BILLING CODE 3410–02–P
List of Subjects in 7 CFR Part 946
SUMMARY: The FAA is revising an
existing airworthiness directive (AD) for
Rolls-Royce plc (RR) RB211 Trent 875,
877, 884, 884B, 892, 892B, and 895
series turbofan engines with certain part
number (P/N) low pressure compressor
(LPC) fan blades installed. That AD
currently requires initial and repetitive
ultrasonic inspections of the fan blade
dovetail roots and defines a specific
terminating action to the repetitive
blade inspection requirements. This AD
requires the same actions but clarifies
the terminating action. We are issuing
this AD to prevent multiple LPC fan
blade failures due to cracks, which
could result in uncontained engine
failure and possible damage to the
airplane.
On
January 3, 2005, we issued AD 2005–
01–15, Amendment 39–13940 (70 FR
2336, January 13, 2005). That AD
superseded AD 2002–11–08,
Amendment 39–12769 (67 FR 38852
June 6, 2002). AD 2005–01–15 requires
initial and repetitive ultrasonic
inspections of the fan blade dovetail
roots, and defines a specific terminating
action to the repetitive blade inspection
requirements. That AD was the result of
a report of a cracked fan blade found
before the blade reached the initial
inspection threshold of AD 2002–11–08.
That AD also reduced the repetitive
inspection compliance time due to
potential breakdown of blade coating
and lubrication on certain blades. Those
conditions, if not corrected, could result
in uncontained engine failure and
possible damage to the airplane.
Marketing agreements, Potatoes,
Reporting and recordkeeping
requirements.
I For the reasons set forth in the
preamble, 7 CFR part 946 is amended as
follows:

(c) Pack and marking:
(1) Domestic: Potatoes packed in

(i) U.S. No. 1 grade or better, except
that potatoes which fail to meet the U.S.
No. 1 grade only because of internal
defects may be shipped without regard
to this requirement provided the lot
contains no more than 10 percent
damage by any internal defect or
combination of internal defects but not
more than 5 percent serious damage by
any internal defect or combination of
internal defects.
(ii) U.S. No. 2 grade, provided the
cartons are permanently and
conspicuously marked as to grade. This
marking requirement does not apply to
cartons containing potatoes meeting the

ACTION: Final rule.
AGENCY:
This AD becomes effective
October 17, 2005. The Director of the
Federal Register previously approved
the incorporation by reference of certain
publications listed in the regulations as
of January 28, 2005 (70 FR 2336, January

Actions Since We Issued AD 2005–01–
15
Since we issued AD 2005–01–15, we
received a comment from an operator
requesting that we clarify the
terminating action in that AD. As that
AD is currently written, you must install
LPC fan blades in complete sets to
comply with the terminating action. Our
intent is that all blades must be replaced
with blades that meet the replacement
criteria to qualify as terminating action,
but not necessarily replaced as a
complete set. In response to the
comment, we published a proposed AD
in the Federal Register on March 9,
2005 (70 FR 11585). That action
proposed to require initial and
repetitive ultrasonic inspections of the
fan blade dovetail roots, and to clarify
a specific terminating action to the
repetitive blade inspection
requirements.
Examining the AD Docket
You may examine the AD Docket
(including any comments and service
information), by appointment, between
8 a.m. and 4:30 p.m., Monday through
Friday, except Federal holidays. See
ADDRESSES for the location.
Comments
We provided the public the
opportunity to participate in the
development of this AD. We received no
comments on the proposal or on the
determination of the cost to the public.

Federal Register / Vol. 70, No. 175 / Monday, September 12, 2005 / Rules and Regulations
Conclusion
We have carefully reviewed the
available data and determined that air
safety and the public interest require
adopting the AD as proposed.
Costs of Compliance
There are about 350 RR RB211 Trent
875, 877, 884, 884B, 892, 892B, and 895
series turbofan engines of the affected
design in the worldwide fleet. We
estimate that 90 engines installed on
airplanes of U.S. registry will be affected
by this AD. We also estimate that it
would take about 8 work hours per
engine to perform the inspections, and
about 260 work hours per engine to
perform the terminating action. The
average labor rate is $65 per work hour.
Based on these figures, we estimate the
total cost of the AD to U.S. operators to
be $1,567,800.
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 this AD:
(1) Is not a ‘‘significant regulatory
action’’ under Executive Order 12866;
(2) Is not a ‘‘significant rule’’ under
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 summary of the costs
to comply with this AD and placed it in
the AD Docket. You may get a copy of
this summary by sending a request to us
at the address listed under ADDRESSES.
Include ‘‘AD Docket No. 2001–NE–17–

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
removing Amendment 39–13940 (70 FR
2336, January 13, 2005), and by adding
the following new airworthiness
directive, Amendment 39–14265:
I
2005–01–15R1 Rolls-Royce plc:
Amendment 39–14265. Docket No.
2001–NE–17–AD.
Effective Date
(a) This airworthiness directive (AD)
becomes effective October 17, 2005.
Affected ADs
(b) This AD revises AD 2005–01–15,
Amendment 39–13940.
Applicability: (c) This AD applies to RollsRoyce plc (RR) RB211 Trent 875, 877, 884,
884B, 892, 892B, and 895 series turbofan

fan blades, part numbers (P/Ns) FK30838,
FK30840, FK30842, FW12960, FW12961,
FW12962, and FW13175, installed. These
engines are installed on, but not limited to,
Boeing Company 777 series airplanes.
Unsafe Condition
(d) This AD revision results from a request
by an operator to clarify the terminating

SUPPLEMENTARY INFORMATION:
DATES:
I. Background
In the Federal Register of December 9,
2004 (69 FR 71562), FDA issued a final
rule to implement section 306 of the
Bioterrorism Act (21 U.S.C. 350c). The
regulation requires the establishment
and maintenance of records by persons
who manufacture, process, pack,
transport, distribute, receive, hold, or
import food in the United States. Such
records are to allow for the
identification of the immediate previous
sources and the immediate subsequent
recipients of food. Persons subject to the
regulation are required to be in
compliance by December 9, 2005, June
9, 2006, or December 11, 2006,

The guidance for industry entitled
‘‘Questions and Answers Regarding
Establishment and Maintenance of
Records’’ responds to questions about
the final rule on records. It is intended
to help industry better understand and
comply with the regulation in 21 CFR
part 1, subpart J. FDA is issuing this
guidance as a level 1 guidance. The
guidance represents the agency’s current
thinking on the topic. It does not create
or confer any rights for or on any person
and does not operate to bind FDA or the

public. Consistent with FDA’s good
guidance practices regulation
§ 10.115(g)(2) (21 CFR 10.115(g)(2)), the
agency will accept comments, but it is
implementing the guidance document
immediately, in accordance with
§ 10.115(g)(2), because the agency has
determined that prior public
participation is not feasible or
appropriate. As noted, the final rule
requires that covered persons begin to
establish and maintain records
identifying the immediate previous
sources and immediate subsequent
recipients of food by December 9, 2005,
June 9, 2006, or December 11, 2006,
depending on the size of the business.
Clarifying the provisions of the final
rule will facilitate prompt compliance
with these requirements and ensure
complete implementation of the final
rule.
FDA continues to receive large
numbers of questions regarding the
records final rule, and is responding to
these questions under § 10.115 as
promptly as possible, using a questionand-answer format. The agency believes
that it is reasonable to maintain all
responses to questions concerning
establishment and maintenance of
records in a single document that is
periodically updated as the agency
receives and responds to additional
questions. The following four indicators
will be employed to help users of the
guidance identify revisions: (1) The
guidance will be identified as a revision
of a previously issued document, (2) the
revision date of the guidance will
appear on its cover, (3) the edition
number of the guidance will be
included in its title, and (4) questions
and answers that have been added to the
original guidance will be identified as
such in the body of the guidance.

14 CFR Part 39
[Docket No. 2001-NE-17-AD; Amendment 39-14265; AD 2005-01-15R1]
RIN 2120-AA64
Airworthiness Directives; Rolls-Royce plc RB211 Trent 875, 877,
884, 884B, 892, 892B, and 895 Series Turbofan Engines
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is revising an existing airworthiness directive (AD)
for Rolls-Royce plc (RR) RB211 Trent 875, 877, 884, 884B, 892, 892B,
and 895 series turbofan engines with certain part number (P/N) low
pressure compressor (LPC) fan blades installed. That AD currently
requires initial and repetitive ultrasonic inspections of the fan blade
dovetail roots and defines a specific terminating action to the
repetitive blade inspection requirements. This AD requires the same
actions but clarifies the terminating action. We are issuing this AD to
prevent multiple LPC fan blade failures due to cracks, which could
result in uncontained engine failure and possible damage to the
airplane.
DATES: This AD becomes effective October 17, 2005. The Director of the
Federal Register previously approved the incorporation by reference of
certain publications listed in the regulations as of January 28, 2005
(70 FR 2336, January 13, 2005).
ADDRESSES: Contact Rolls-Royce plc, P.O. Box 31, Derby DE24 6BJ, UK;
telephone 44 (0) 1332 242424; fax 44 (0) 1332 249936, for the service
information identified in this AD.
You may examine the AD docket at the FAA, New England Region,
Office of the Regional Counsel, 12 New England Executive Park,
Burlington, MA. You may examine the service information, at the FAA,
New England Region, Office of the Regional Counsel, 12 New England
Executive Park, Burlington, MA.
FOR FURTHER INFORMATION CONTACT: Christopher Spinney, Aerospace
Engineer, Engine Certification Office, FAA, Engine and Propeller
Directorate, 12 New England Executive Park, Burlington, MA 01803-5299;
telephone (781) 238-7175; fax (781) 238-7199.
SUPPLEMENTARY INFORMATION: On January 3, 2005, we issued AD 2005-01-15,
Amendment 39-13940 (70 FR 2336, January 13, 2005). That AD superseded
AD 2002-11-08, Amendment 39-12769 (67 FR 38852 June 6, 2002). AD 2005-
01-15 requires initial and repetitive ultrasonic inspections of the fan
blade dovetail roots, and defines a specific terminating action to the
repetitive blade inspection requirements. That AD was the result of a
report of a cracked fan blade found before the blade reached the
initial inspection threshold of AD 2002-11-08. That AD also reduced the
repetitive inspection compliance time due to potential breakdown of
blade coating and lubrication on certain blades. Those conditions, if
not corrected, could result in uncontained engine failure and possible
damage to the airplane.
Actions Since We Issued AD 2005-01-15
Since we issued AD 2005-01-15, we received a comment from an
operator requesting that we clarify the terminating action in that AD.
As that AD is currently written, you must install LPC fan blades in
complete sets to comply with the terminating action. Our intent is that
all blades must be replaced with blades that meet the replacement
criteria to qualify as terminating action, but not necessarily replaced
as a complete set. In response to the comment, we published a proposed
AD in the Federal Register on March 9, 2005 (70 FR 11585). That action
proposed to require initial and repetitive ultrasonic inspections of
the fan blade dovetail roots, and to clarify a specific terminating
action to the repetitive blade inspection requirements.
Examining the AD Docket
You may examine the AD Docket (including any comments and service
information), by appointment, between 8 a.m. and 4:30 p.m., Monday
through Friday, except Federal holidays. See ADDRESSES for the
location.
Comments
We provided the public the opportunity to participate in the
development of this AD. We received no comments on the proposal or on
the determination of the cost to the public.
[[Page 53726]]
Conclusion
We have carefully reviewed the available data and determined that
air safety and the public interest require adopting the AD as proposed.
Costs of Compliance
There are about 350 RR RB211 Trent 875, 877, 884, 884B, 892, 892B,
and 895 series turbofan engines of the affected design in the worldwide
fleet. We estimate that 90 engines installed on airplanes of U.S.
registry will be affected by this AD. We also estimate that it would
take about 8 work hours per engine to perform the inspections, and
about 260 work hours per engine to perform the terminating action. The
average labor rate is $65 per work hour. Based on these figures, we
estimate the total cost of the AD to U.S. operators to be $1,567,800.
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 this AD:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866;
(2) Is not a ``significant rule'' under 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 summary of the costs to comply with this AD and
placed it in the AD Docket. You may get a copy of this summary by
sending a request to us at the address listed under ADDRESSES. Include
``AD Docket No. 2001-NE-17-AD'' in your request.
