The FAA
proposed to amend 14 CFR part 39 with
a proposed AD. The proposed AD
applies to Rolls-Royce Deutschland Ltd
& Co KG (RRD) (formerly Rolls-Royce
Deutschland GmbH, formerly BMW
Rolls-Royce GmbH) models BR700–
710A1–10 and BR700–710A2–20
turbofan engines. We published the
proposed AD in the Federal Register on
July 5, 2005 (70 FR 38627). That action
proposed to require initial and
repetitive inspections for cracks in fan
discs P/Ns BRR18803, BRR19248,
BRR20791, BRR24829, and FW33929.
That action also proposed as optional
terminating action to the repetitive
inspection requirements, installation of
a new fan disc P/N FW33927, new fan
blades P/N FW33513 or P/N FW33980,
and N1 Keep Out Zone software.
SUPPLEMENTARY INFORMATION:
SUMMARY: The FAA is superseding an
existing airworthiness directive (AD) for
Rolls-Royce Deutschland Ltd & Co KG
(RRD) (formerly Rolls-Royce
Deutschland GmbH, formerly BMW
Rolls-Royce GmbH) models BR700–
710A1–10 and BR700–710A2–20
turbofan engines. That AD currently
requires initial and repetitive visual and
ultrasonic inspections of fan discs, part
numbers (P/Ns) BRR18803, BRR19248,
and BRR20791 for cracks, and if
necessary, replacement with serviceable
parts. This ad requires those same
inspections for discs having old design
P/N fan blades installed, and, extends
the inspection interval for fan discs
having new design P/N fan blades
installed. Also, this AD adds as optional
terminating action to the inspections,
installation of certain P/N new fan
discs, certain P/N new fan blades, and
engine fan speed (N1) Keep Out Zone
software. This AD results from a revised
RRD service bulletin (SB) that
introduces relaxed inspection intervals
for certain P/N combinations of fan

Federal Register / Vol. 70, No. 203 / Friday, October 21, 2005 / Rules and Regulations
Comments
We provided the public the
opportunity to participate in the
development of this AD. We have
considered the comments received.
Request To Cancel Inspections
One commenter, RRD, requests we
cancel the inspections in paragraphs
(f)(1), (g)(1), (f)(3), and (g)(3), as these
inspections have been conducted on all
hardware in service, and are no longer
needed. We disagree. Mandatory actions
that published in the superseded AD
need to be carried forward in the
superseding AD. The operator can then
determine if the affected engine is in
compliance with all mandatory actions.
Add Applicable Fan Blade Part
Numbers to Paragraph (h)
The same commenter requests that we
add the applicable fan blade part
numbers in paragraph (h), for clarity, as
we did in paragraph (g). We agree and
have added fan blades P/N BRR20677
and BRR23178 to paragraph (h).
Request To Cover Engines That Had a
New Disc Installed on, or After,
January 1, 2002
The same commenter requests that we
cover engines that had a new
production fan disc installed on or after
January 1, 2002, in a new paragraph in
the compliance section. The commenter
states that these fan discs already had a
visual and ultrasonic inspection before
delivery and installation, and only
require initial inspection at 150 flight
cycles-since-new. These engines are not
appropriately covered by the proposed
AD. We agree and have added a
paragraph to the compliance section to
cover these engines.
Request To Directly Identify
Requirements
The same commenter requests that we
clarify paragraphs (i) and (j) by directly
identifying the requirements, instead of
referring to other paragraphs. We agree
and have changed paragraphs (i) and (j)
to identify the requirements.
Request To Change Repetitive
Inspection Interval
The same commenter requests that in
paragraphs (k)(1) and (k)(2), we change
the inspection interval time requirement
from flight hours, to A-Check. The
commenter states that the proposed AD
does not reflect the requirements of RRD
SB No. SB–BR700–72–900229, Revision
6, dated February 23, 2005. The visual
and ultrasonic inspections were always
aligned with the scheduled airplane
maintenance A-Check. The commenter
further states that the A-Check occurs
VerDate Aug<31>2005
14:34 Oct 20, 2005
Jkt 208001
every 500-to-550 flight hours. We
partially agree. We consider the ACheck to occur at an indefinite interval
that can vary from operator to operator.
However, in this case, we have changed
the compliance in paragraph (k)(1) to
perform a visual and ultrasonic
inspection before accumulating 550
flight hours-since-new. We also changed
paragraph (k)(2) to perform a visual and
ultrasonic inspection at every A-Check
but not to exceed 550 hours-since-the
last visual and ultrasonic inspection.
Request To Remove Inspection
Requirements From the AD and
Reference the Time Limits Manual
The same commenter requests that we
remove the inspection requirements
from paragraph (l) of the proposed AD,
which is for engines with fan disc P/N
BRR20791, BRR24829, or FW33929
installed, and fan blades P/N FW33513,
FW33980, FW33925, FW34114, or
FW34776 installed. The commenter
requests that we refer to the applicable
RRD Time Limits Manual that mandates
the inspections for these fan disc-andblade-engine configurations. We agree
and have changed that paragraph in the
AD.
Request To Clarify the Optional
Terminating Action
The same commenter requests that in
the optional terminating action
paragraph, we change the phrase ‘‘is
optional terminating action to the
repetitive inspections required by this
AD’’ to ‘‘is optional terminating action
to any inspection required by this AD’’.
The commenter states that once the
parts and the Keep Out Zone software
referenced in the optional terminating
action paragraph are installed, none of
the inspections in the AD are required.
We agree and have made that change in
the AD.
Request To Reference the Latest Service
Bulletin
The same commenter requests that we
reference the latest service bulletin in
the Inspection Reporting Requirements
paragraph, which is RRD SB No. SB–
BR700–72–900229, Revision 6, dated
February 23, 2005. We agree and have
made that change in the AD.
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.

Costs of Compliance
There are about 500 RRD models
BR700–710A1–10 and BR700–710A2–
20 turbofan engines of the affected
design in the worldwide fleet. We
estimate that 400 engines installed on
airplanes of U.S. registry are affected by
this AD. We also estimate that it will
take about 7 work hours per engine to
perform the inspections, and that the
average labor rate is $65 per work hour.
We estimate the total labor cost for
performing one inspection of the U.S.
fleet to be $182,000. New design fan
discs and fan blades will cost about
$150,000 per engine. Based on these
figures, the total cost of the AD on U.S.
operators is estimated to be $60,182,000.
The manufacturer has stated that it may
provide the new fan disc and new fan
blades at no cost to operators.
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.

Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG
(Formerly Rolls-Royce Deutschland GmbH, formerly BMW Rolls-Royce GmbH)
Models BR700-710A1-10 and BR700-710A2-20 Turbofan Engines
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding an existing airworthiness directive
(AD) for Rolls-Royce Deutschland Ltd & Co KG (RRD) (formerly Rolls-
Royce Deutschland GmbH, formerly BMW Rolls-Royce GmbH) models BR700-
710A1-10 and BR700-710A2-20 turbofan engines. That AD currently
requires initial and repetitive visual and ultrasonic inspections of
fan discs, part numbers (P/Ns) BRR18803, BRR19248, and BRR20791 for
cracks, and if necessary, replacement with serviceable parts. This ad
requires those same inspections for discs having old design P/N fan
blades installed, and, extends the inspection interval for fan discs
having new design P/N fan blades installed. Also, this AD adds as
optional terminating action to the inspections, installation of certain
P/N new fan discs, certain P/N new fan blades, and engine fan speed
(N1) Keep Out Zone software. This AD results from a revised RRD service
bulletin (SB) that introduces relaxed inspection intervals for certain
P/N combinations of fan discs and fan blades, and introduces improved
design fan discs and fan blades.
DATES: This AD becomes effective November 25, 2005. The Director of the
Federal Register approved the incorporation by reference of certain
publications listed in the regulations as of November 25, 2005. The
Director of the Federal Register previously approved the incorporation
by reference of certain other publications as listed in the regulations
as of April 28, 2003 (68 FR 17727, April 11, 2003).

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39
with a proposed AD. The proposed AD applies to Rolls-Royce Deutschland
Ltd & Co KG (RRD) (formerly Rolls-Royce Deutschland GmbH, formerly BMW
Rolls-Royce GmbH) models BR700-710A1-10 and BR700-710A2-20 turbofan
engines. We published the proposed AD in the Federal Register on July
5, 2005 (70 FR 38627). That action proposed to require initial and
repetitive inspections for cracks in fan discs P/Ns BRR18803, BRR19248,
BRR20791, BRR24829, and FW33929. That action also proposed as optional
terminating action to the repetitive inspection requirements,
installation of a new fan disc P/N FW33927, new fan blades P/N FW33513
or P/N FW33980, and N1 Keep Out Zone software.
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.
[[Page 61230]]
Comments
We provided the public the opportunity to participate in the
development of this AD. We have considered the comments received.
Request To Cancel Inspections
One commenter, RRD, requests we cancel the inspections in
paragraphs (f)(1), (g)(1), (f)(3), and (g)(3), as these inspections
have been conducted on all hardware in service, and are no longer
needed. We disagree. Mandatory actions that published in the superseded
AD need to be carried forward in the superseding AD. The operator can
then determine if the affected engine is in compliance with all
mandatory actions.
Add Applicable Fan Blade Part Numbers to Paragraph (h)
The same commenter requests that we add the applicable fan blade
part numbers in paragraph (h), for clarity, as we did in paragraph (g).
We agree and have added fan blades P/N BRR20677 and BRR23178 to
paragraph (h).
Request To Cover Engines That Had a New Disc Installed on, or After,
January 1, 2002
The same commenter requests that we cover engines that had a new
production fan disc installed on or after January 1, 2002, in a new
paragraph in the compliance section. The commenter states that these
fan discs already had a visual and ultrasonic inspection before
delivery and installation, and only require initial inspection at 150
flight cycles-since-new. These engines are not appropriately covered by
the proposed AD. We agree and have added a paragraph to the compliance
section to cover these engines.
Request To Directly Identify Requirements
The same commenter requests that we clarify paragraphs (i) and (j)
by directly identifying the requirements, instead of referring to other
paragraphs. We agree and have changed paragraphs (i) and (j) to
identify the requirements.
Request To Change Repetitive Inspection Interval
The same commenter requests that in paragraphs (k)(1) and (k)(2),
we change the inspection interval time requirement from flight hours,
to A-Check. The commenter states that the proposed AD does not reflect
the requirements of RRD SB No. SB-BR700-72-900229, Revision 6, dated
February 23, 2005. The visual and ultrasonic inspections were always
aligned with the scheduled airplane maintenance A-Check. The commenter
further states that the A-Check occurs every 500-to-550 flight hours.
We partially agree. We consider the A-Check to occur at an indefinite
interval that can vary from operator to operator. However, in this
case, we have changed the compliance in paragraph (k)(1) to perform a
visual and ultrasonic inspection before accumulating 550 flight hours-
since-new. We also changed paragraph (k)(2) to perform a visual and
ultrasonic inspection at every A-Check but not to exceed 550 hours-
since-the last visual and ultrasonic inspection.
Request To Remove Inspection Requirements From the AD and Reference the
Time Limits Manual
The same commenter requests that we remove the inspection
requirements from paragraph (l) of the proposed AD, which is for
engines with fan disc P/N BRR20791, BRR24829, or FW33929 installed, and
fan blades P/N FW33513, FW33980, FW33925, FW34114, or FW34776
installed. The commenter requests that we refer to the applicable RRD
Time Limits Manual that mandates the inspections for these fan disc-
and-blade-engine configurations. We agree and have changed that
paragraph in the AD.
Request To Clarify the Optional Terminating Action
The same commenter requests that in the optional terminating action
paragraph, we change the phrase ``is optional terminating action to the
repetitive inspections required by this AD'' to ``is optional
terminating action to any inspection required by this AD''. The
commenter states that once the parts and the Keep Out Zone software
referenced in the optional terminating action paragraph are installed,
none of the inspections in the AD are required. We agree and have made
that change in the AD.
Request To Reference the Latest Service Bulletin
The same commenter requests that we reference the latest service
bulletin in the Inspection Reporting Requirements paragraph, which is
RRD SB No. SB-BR700-72-900229, Revision 6, dated February 23, 2005. We
agree and have made that change in the AD.
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.
Costs of Compliance
There are about 500 RRD models BR700-710A1-10 and BR700-710A2-20
turbofan engines of the affected design in the worldwide fleet. We
estimate that 400 engines installed on airplanes of U.S. registry are
affected by this AD. We also estimate that it will take about 7 work
hours per engine to perform the inspections, and that the average labor
rate is $65 per work hour. We estimate the total labor cost for
performing one inspection of the U.S. fleet to be $182,000. New design
fan discs and fan blades will cost about $150,000 per engine. Based on
these figures, the total cost of the AD on U.S. operators is estimated
to be $60,182,000. The manufacturer has stated that it may provide the
new fan disc and new fan blades at no cost to operators.
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.

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
