AD requires removing affected rotating
parts overhauled by a certain repair
vendor, and inspecting the parts as
applicable. This AD results from reports
that certain JT8D critical life-limited
rotating parts have been returned to
service with cracks, corrosion pitting, or
dimensions outside of manual limits.
We are issuing this AD to prevent
failure of critical life-limited rotating
engine parts which could result in an
uncontained engine failure and damage
to the airplane.
This AD becomes effective
September 30, 2005. The Director of the
Federal Register approved the
incorporation by reference of certain
publications listed in the regulations as
of September 30, 2005.
DATES:
You can get the service
information identified in this AD from

The FAA
proposed to amend 14 CFR part 39 with
a proposed airworthiness directive (AD).
The proposed AD applies to Pratt &
Whitney (PW) JT8D–1, –1A, –1B, –7,
–7A, –7B, –9, –9A, –11, –15, –15A, –17,
–17A, –17R, –17AR, –209, –217, –217A,
–217C, and –219 turbofan engines. We
published the proposed AD in the
Federal Register on December 30, 2004
(69 FR 78359). That action proposed to
require removing affected rotating parts
overhauled by a certain repair vendor,
and inspecting or replacing the parts as
applicable.
SUPPLEMENTARY INFORMATION:
Examining the AD Docket
You may examine the docket that
contains the AD, any comments
received, and any final disposition in
person at the DMS Docket Offices
between 9 a.m. and 5 p.m., Monday
through Friday, except Federal holidays.
The Docket Office (telephone (800) 647–
5227) is located on the plaza level of the
Department of Transportation Nassif
Building at the street address stated in
ADDRESSES. Comments will be available
in the AD docket shortly after the DMS
receives them.

Comments
We provided the public the
opportunity to participate in the
development of this AD. We have
considered the comments received.
Request To Remove Rear Compressor
Rear Hub From List of Affected Parts
One commenter requests that we
remove the rear compressor rear hub
from the list of affected parts. The
commenter states that the part is a
nickel alloy similar to the 13th stage
disk and there is no cracking or
corrosion associated with it. In addition,
the rear compressor rear hub is not a
life-limited part, and the serial numbers
are not readily available. As a result, the
commenter feels the proposed AD
would force operators to inspect all
parts, not just the listed serial number
parts.
We agree. We have removed it from
this AD.
Include All Parts Improperly Processed
by the Repair Vendor
One commenter asks that this AD
include all parts improperly processed
by a certain repair vendor, not just the
high-pressure compressor.
We do not agree. The proposed AD
addresses those parts that pose a safety
threat. All other parts either present no
known safety threat, or are already
addressed through other applicable ADs
and field notifications. If we decide that
further AD action is necessary to
address other parts, we may issue a
separate AD at that time.
Request To Clarify ‘‘Shop Visit’’
One commenter asks that we clarify
the definition of ‘‘shop visit’’ contained
in the AD. The commenter feels that an
operator could interpret a shop visit as
when an airplane upon which an
affected engine is installed, goes into a
hangar.
We agree. We included the following
definition in the AD: ‘‘A shop visit is
defined as an engine removal where
engine maintenance entails separation
of pairs of major engine flanges or the
removal of a disk, hub or spool at a
maintenance facility, regardless of the
scheduled maintenance action or the
reason for engine removal.’’
Request To Inspect Rear Compressor
Front and Rear Compressor Rear Hubs
When They Are Accessible
One commenter asks that we not
place time restrictions on operators to
inspect rear compressor front and rear
compressor rear hubs and instead
inspect them when they are accessible.
Because they aren’t life-limited parts,
the hubs are not tracked by serial
E:\FR\FM\26AUR1.SGM
26AUR1
Federal Register / Vol. 70, No. 165 / Friday, August 26, 2005 / Rules and Regulations

numbers. The commenter believes the
proposed AD would require operators to
inspect every JT8D before March 31,
2008. Those inspections would force
early removal of many engines. We
partially agree. Table 1 of this AD lists
all life-limited rear compressor front
hubs, and operators must inspect them
by the March 31, 2008, deadline. Table
2 of this AD lists all rear compressor
front hubs that are non-life limited.
Operators must inspect them at the next
accessibility. We removed the rear
compressor rear hubs from this AD,
based on a previous comment.
in this AD to prevent ‘‘operation of a
part physically installed in a module.’’
We do not agree. A definition of
‘‘installed part’’ is unnecessary because
this proposed AD prohibits all parts
with zero cycles-in-service that are
listed in Table 1 from entering service,
regardless of whether they are installed
or not. However, we added a new
paragraph (h) to prevent installing any
engine that has an affected disk or hub
that has zero cycles-in-service after May
14, 2001, and recodified the subsequent
paragraphs.
regularly scheduled maintenance, and
will require 66 work hours per engine.
The high pressure compressor section of
the remaining 474 engines will be
inspected during regularly scheduled
maintenance, and will not require
additional labor costs to inspect. The
average labor rate is $65 per work hour.
We estimate that half of the parts
presently installed will require
replacement, at a cost of approximately
$6,730,800. Based on this information,
we estimate the total cost of the AD to
U.S. operators to be $7,398,620.
Operators’ Cost
Authority for This Rulemaking
Compliance Date
One commenter asks us to explain
how we determined the March 31, 2008
compliance date. The commenter states
that it is unclear how we selected that
compliance date since corrosion
inspection ADs 2003–16–05 and 2003–
12–07, as well as PW ASBs A6431 and
A6435, designate July 18, 2011, as a
compliance date.
We evaluated the results of a risk
analysis based on inspection data
obtained from a sample of parts repaired
by the repair vendor. That analysis
demonstrated a greater risk of failure if
the parts were only inspected for
corrosion and not for cracking as
mandated in ADs 2003–16–05 and
2003–12–07. Based on that risk analysis,
we set March 31, 2008, as the date by
which operators must complete the
inspections.
One commenter asks that we explain
the cost to operators, suggesting that we
evaluate the cost as if every part fails
inspection. The commenter states that
the current market value for all affected
parts is $14,413,020, and the cost to
disassemble, inspect and reassemble
engines outside of regularly scheduled
maintenance is $1,766,440.
We disagree. We still consider our
evaluation of cost as noted in the NPRM
valid. We do not expect that every part
will fail the inspection, although we
estimate that the number will be
substantial. In addition, we did not
include the full cost of every disk in the
economic analysis if the disks must be
replaced before they reach their certified
life, a normal operating expense.
Accordingly, we didn’t change the Costs
to Comply.
Use of Certain Parts as Serviceable
Parts
One commenter recommends
inspecting all parts listed in Tables 1
and 2 that have zero cycles-in-service
since May 14, 2001, using PW ASB
A6442 and made available for use as
spare parts.
We do not agree. Parts listed in Table
1 were subjected to shot peening that
could mask surface cracks. Parts listed
in Table 2 were not. If the parts in Table
1 were cracked and, thereafter, shot
peened, the cracks will reopen once
operated in an engine, a significant
factor in our risk analysis and the
resulting compliance schedule in the
proposed AD. Since there is no effective
inspection to detect these cracks,
operators may use only parts that have
been in service. This is consistent with
the manufacturer’s disposition
instructions in ASB A6442 that state,
‘‘All compressor disks and hubs listed
in Table 1 that are not installed in an
engine MUST be scrapped.’’
One commenter asks that we add a
sentence to Paragraph (g) that reads
‘‘This includes all parts on the shelf that
have not been used.’’
We do not agree. This AD is clear as
written. We have not added the
sentence.
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.

definition of installed part be included

Conclusion
We have carefully reviewed the
available data, including the comments
received, and determined that air safety
and the public interest require adopting
the AD with the changes described
previously. We have determined that
these changes will neither increase the
economic burden on any operator nor
increase the scope of the AD.
Interim Action
These actions are interim actions and
we might take further rulemaking action
in the future.
Costs of Compliance
We estimate that this AD will affect
about 632 JT8D engines installed on
airplanes of U.S. registry. We estimate
that 158 engines will require access to
the high-pressure compressor outside of

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 at the address listed
under ADDRESSES.

Fastener Quality Act
National Institute of Standards
and Technology, United States
Department of Commerce.
ACTION: Final rule.
AGENCY:
SUMMARY: The Director of the National
Institute of Standards and Technology
(NIST), United States Department of
Commerce, and the Director of the
United States Patent and Trademark
Office (USPTO), United States
Department of Commerce, are amending
the rules that implement the Fastener
Quality Act of 1999 to provide that all
documents submitted in connection
with the recordal of fastener insignia
must be mailed to a particular postal
box maintained by United States Patent
and Trademark Office.
DATES: This final rule is effective on
September 26, 2005.
FOR FURTHER INFORMATION CONTACT: Ari
Leifman, Office of the Commissioner for
Trademarks, P.O. Box 1451, Alexandria,
Virginia 22313–1451, telephone number
(571) 272–9572.
SUPPLEMENTARY INFORMATION:
Background
The Fastener Quality Act of 1999,
Public Law 101–592 (as amended by
Pub. L. 104–113, Pub. L. 105–234 and
Pub. L. 106–34) requires the Secretary of
Commerce to establish a program for the
recordation of the identifying insignia of
certain fasteners. The rules set forth at
Subpart D of 15 CFR 280.300 et seq.
accordingly provide for a recordation
system, and that system is maintained at
the United States Patent and Trademark
Office (USPTO). One of the rules, 15
CFR 280.310(d), provides that all
documents pertaining to recordation
must be mailed to a particular postal
box maintained by the USPTO in
Washington, DC.
The efficiency of the insignia
recordation program will be enhanced if
documents submitted in connection
PO 00000
Frm 00032
Fmt 4700
Sfmt 4700
with the program are mailed to a postal
box that is close to the USPTO’s
headquarters in Alexandria, Virginia.
Accordingly, Section 280.310(d) is
amended to provide that these
documents be mailed to that postal box.
This final rule amends section 280.30,
Application for Insignia, to identify the
postal box to which all documents
pertaining to recordation should be sent.
Additional Information
Executive Order 12866
This rule of agency organization and
management is not subject to Executive
Order 12866.
Executive Order 12612
This rule does not contain policies
with Federalism implications sufficient
to warrant preparation of a Federalism
assessment under Executive Order
12612.
Administrative Procedure Act
Prior notice and an opportunity for
public comment are not required for this
rule of agency organization, procedure,
or practice. 5 U.S.C. 553(b)(A). This rule
revises the regulations to identify the
address where documents submitted in
connection with the recordal of fastener
insignia may be mailed.
Regulatory Flexibility Act
Because notice and comment are not
required under 5 U.S.C. 553, or any
other law, the analytical requirements of
the Regulatory Flexibility Act (5 U.S.C.
601 et seq.) are inapplicable. As such, a
regulatory flexibility analysis is not
required.
Paperwork Reduction Act
This rule involves a collection of
information that is subject to the
Paperwork Reduction Act (PRA), and
that has been approved by the Office of
Management and Budget (OMB) under
control number 0651–0028.
Notwithstanding any other provision of
the law, no person is required to
comply, nor shall any person be subject
to penalty for failure to comply with, a
collection of information, subject to the
requirements of the Paperwork
Reduction Act, unless that collection of
information displays a currently valid
OMB Control Number.

AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
Pratt & Whitney (PW) JT8D-1, -1A, -1B, -7, -7A, -7B, -9, -9A, -11, -15,
-15A, -17, -17A, -17R, -17AR, -209, -217, -217A, -217C, and -219
turbofan engines. This AD requires removing affected rotating parts
overhauled by a certain repair vendor, and inspecting the parts as
applicable. This AD results from reports that certain JT8D critical
life-limited rotating parts have been returned to service with cracks,
corrosion pitting, or dimensions outside of manual limits. We are
issuing this AD to prevent failure of critical life-limited rotating
engine parts which could result in an uncontained engine failure and
damage to the airplane.
DATES: This AD becomes effective September 30, 2005. The Director of
the Federal Register approved the incorporation by reference of certain
publications listed in the regulations as of September 30, 2005.
ADDRESSES: You can get the service information identified in this AD
from Pratt & Whitney, 400 Main St., East Hartford, CT 06108; telephone
(860) 565-7700; fax (860) 565-1605.
You may examine the AD docket on the Internet at https://dms.dot.gov
or in Room PL-401 on the plaza level of the Nassif Building, 400
Seventh Street, SW., Washington, DC.

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39
with a proposed airworthiness directive (AD). The proposed AD applies
to Pratt & Whitney (PW) JT8D-1, -1A, -1B, -7, -7A, -7B, -9, -9A, -11, -
15, -15A, -17, -17A, -17R, -17AR, -209, -217, -217A, -217C, and -219
turbofan engines. We published the proposed AD in the Federal Register
on December 30, 2004 (69 FR 78359). That action proposed to require
removing affected rotating parts overhauled by a certain repair vendor,
and inspecting or replacing the parts as applicable.
Examining the AD Docket
You may examine the docket that contains the AD, any comments
received, and any final disposition in person at the DMS Docket Offices
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The Docket Office (telephone (800) 647-5227) is located on
the plaza level of the Department of Transportation Nassif Building at
the street address stated in ADDRESSES. Comments will be available in
the AD docket shortly after the DMS receives them.
Comments
We provided the public the opportunity to participate in the
development of this AD. We have considered the comments received.
Request To Remove Rear Compressor Rear Hub From List of Affected Parts
One commenter requests that we remove the rear compressor rear hub
from the list of affected parts. The commenter states that the part is
a nickel alloy similar to the 13th stage disk and there is no cracking
or corrosion associated with it. In addition, the rear compressor rear
hub is not a life-limited part, and the serial numbers are not readily
available. As a result, the commenter feels the proposed AD would force
operators to inspect all parts, not just the listed serial number
parts.
We agree. We have removed it from this AD.
Include All Parts Improperly Processed by the Repair Vendor
One commenter asks that this AD include all parts improperly
processed by a certain repair vendor, not just the high-pressure
compressor.
We do not agree. The proposed AD addresses those parts that pose a
safety threat. All other parts either present no known safety threat,
or are already addressed through other applicable ADs and field
notifications. If we decide that further AD action is necessary to
address other parts, we may issue a separate AD at that time.
Request To Clarify ``Shop Visit''
One commenter asks that we clarify the definition of ``shop visit''
contained in the AD. The commenter feels that an operator could
interpret a shop visit as when an airplane upon which an affected
engine is installed, goes into a hangar.
We agree. We included the following definition in the AD: ``A shop
visit is defined as an engine removal where engine maintenance entails
separation of pairs of major engine flanges or the removal of a disk,
hub or spool at a maintenance facility, regardless of the scheduled
maintenance action or the reason for engine removal.''
Request To Inspect Rear Compressor Front and Rear Compressor Rear Hubs
When They Are Accessible
One commenter asks that we not place time restrictions on operators
to inspect rear compressor front and rear compressor rear hubs and
instead inspect them when they are accessible. Because they aren't
life-limited parts, the hubs are not tracked by serial
[[Page 50171]]
numbers. The commenter believes the proposed AD would require operators
to inspect every JT8D before March 31, 2008. Those inspections would
force early removal of many engines. We partially agree. Table 1 of
this AD lists all life-limited rear compressor front hubs, and
operators must inspect them by the March 31, 2008, deadline. Table 2 of
this AD lists all rear compressor front hubs that are non-life limited.
Operators must inspect them at the next accessibility. We removed the
rear compressor rear hubs from this AD, based on a previous comment.
Compliance Date
One commenter asks us to explain how we determined the March 31,
2008 compliance date. The commenter states that it is unclear how we
selected that compliance date since corrosion inspection ADs 2003-16-05
and 2003-12-07, as well as PW ASBs A6431 and A6435, designate July 18,
2011, as a compliance date.
We evaluated the results of a risk analysis based on inspection
data obtained from a sample of parts repaired by the repair vendor.
That analysis demonstrated a greater risk of failure if the parts were
only inspected for corrosion and not for cracking as mandated in ADs
2003-16-05 and 2003-12-07. Based on that risk analysis, we set March
31, 2008, as the date by which operators must complete the inspections.
Use of Certain Parts as Serviceable Parts
One commenter recommends inspecting all parts listed in Tables 1
and 2 that have zero cycles-in-service since May 14, 2001, using PW ASB
A6442 and made available for use as spare parts.
We do not agree. Parts listed in Table 1 were subjected to shot
peening that could mask surface cracks. Parts listed in Table 2 were
not. If the parts in Table 1 were cracked and, thereafter, shot peened,
the cracks will reopen once operated in an engine, a significant factor
in our risk analysis and the resulting compliance schedule in the
proposed AD. Since there is no effective inspection to detect these
cracks, operators may use only parts that have been in service. This is
consistent with the manufacturer's disposition instructions in ASB
A6442 that state, ``All compressor disks and hubs listed in Table 1
that are not installed in an engine MUST be scrapped.''
Definition of Installed Part
One commenter requests that the definition of installed part be
included in this AD to prevent ``operation of a part physically
installed in a module.''
We do not agree. A definition of ``installed part'' is unnecessary
because this proposed AD prohibits all parts with zero cycles-in-
service that are listed in Table 1 from entering service, regardless of
whether they are installed or not. However, we added a new paragraph
(h) to prevent installing any engine that has an affected disk or hub
that has zero cycles-in-service after May 14, 2001, and recodified the
subsequent paragraphs.
Operators' Cost
One commenter asks that we explain the cost to operators,
suggesting that we evaluate the cost as if every part fails inspection.
The commenter states that the current market value for all affected
parts is $14,413,020, and the cost to disassemble, inspect and
reassemble engines outside of regularly scheduled maintenance is
$1,766,440.
We disagree. We still consider our evaluation of cost as noted in
the NPRM valid. We do not expect that every part will fail the
inspection, although we estimate that the number will be substantial.
In addition, we did not include the full cost of every disk in the
economic analysis if the disks must be replaced before they reach their
certified life, a normal operating expense. Accordingly, we didn't
change the Costs to Comply.
Add Spare Parts to Paragraph (g)
One commenter asks that we add a sentence to Paragraph (g) that
reads ``This includes all parts on the shelf that have not been used.''
We do not agree. This AD is clear as written. We have not added the
sentence.
Conclusion
We have carefully reviewed the available data, including the
comments received, and determined that air safety and the public
interest require adopting the AD with the changes described previously.
We have determined that these changes will neither increase the
economic burden on any operator nor increase the scope of the AD.
Interim Action
These actions are interim actions and we might take further
rulemaking action in the future.
Costs of Compliance
We estimate that this AD will affect about 632 JT8D engines
installed on airplanes of U.S. registry. We estimate that 158 engines
will require access to the high-pressure compressor outside of
regularly scheduled maintenance, and will require 66 work hours per
engine. The high pressure compressor section of the remaining 474
engines will be inspected during regularly scheduled maintenance, and
will not require additional labor costs to inspect. The average labor
rate is $65 per work hour. We estimate that half of the parts presently
installed will require replacement, at a cost of approximately
$6,730,800. Based on this information, we estimate the total cost of
the AD to U.S. operators to be $7,398,620.
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 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 at the
address listed under ADDRESSES.

Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive:
2005-17-16 Pratt & Whitney: Amendment 39-14237. Docket No. FAA-2004-
19929; Directorate Identifier 2004-NE-15-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective
September 30, 2005.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Pratt & Whitney (PW) JT8D-1, -1A, -1B, -
