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 PO 00000 61229 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. E:\FR\FM\21OCR1.SGM 21OCR1 61230 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. PO 00000 Frm 00020 Fmt 4700 Sfmt 4700 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. E:\FR\FM\21OCR1.SGM 21OCR1 Federal Register / Vol. 70, No. 203 / Friday, October 21, 2005 / Rules and Regulations We prepared a summary of the costs to comply with this AD and placed it in the AD Docket.

14 CFR Part 39

[Docket No. 2000-NE-48-AD; Amendment 39-14343; AD 2005-21-05]
RIN 2120-AA64


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.
