SUMMARY: The FAA is adopting a new
airworthiness directive (AD) for certain
Rolls-Royce plc (RR) RB211 Trent 553–
61, 553A2–61, 556–61, 556A2–61,
556B–61, 556B2–61, 560–61, and
560A2–61 turbofan engines. This AD

requires initial and repetitive borescope
inspections for missing HPT rear seal
plate locking plugs and damaged
locking plug retaining wires, and
removal of the engine from service if
necessary, based on inspection results.
This AD results from two reports of
missing HPT rear seal plate locking
plugs, damage to the HPT disc, and
damage to the remaining locking plug
retaining wires. We are issuing this AD
to prevent uncontained release of the
HPT rear side plate and HPT disc,
resulting in damage to the airplane.
DATES: Effective February 16, 2006. The
Director of the Federal Register
approved the incorporation by reference
of certain publications listed in the
regulations as of February 16, 2006.
We must receive any comments on
this AD by April 3, 2006.

SUPPLEMENTARY INFORMATION: The Civil
Aviation Authority (CAA), which is the
E:\FR\FM\01FER1.SGM
01FER1
Federal Register / Vol. 71, No. 21 / Wednesday, February 1, 2006 / Rules and Regulations
airworthiness authority for the United
Kingdom (U.K.), notified us that an
unsafe condition may exist on RR
RB211 Trent 500 series turbofan engines
that have not incorporated RR Service
Bulletin (SB) No. RB.211–72–E767. The
CAA advises that during shop visit,
some engines were noticed to be
missing some of the HPT turbine rear
seal plate locking plugs. This resulted in
scoring of the HPT disc rear diaphragm
and impact damage to the remaining
locking plug retaining wires, and could
have led to release of the HPT rear seal
plate and reduced low-cycle-fatigue life
of the HPT disc.
Relevant Service Information
We have reviewed and approved the
technical contents of RR Alert SB No.
RB.211–72–AE358, Revision 3, dated
July 13, 2005, that describes procedures
for borescope inspecting the HPT rear
seal plate locking plugs and locking
plug retaining wires. The CAA classified
this as a mandatory SB and issued AD
G–2005–0007 R1, dated July 11, 2005, in
order to ensure the airworthiness of
these RB211 Trent 500 series turbofan
engines in the U.K.

Bilateral Airworthiness Agreement
These RB211 Trent 553–61, 553A2–
61, 556–61, 556A2–61, 556B–61,
556B2–61, 560–61, and 560A2–61 series
turbofan engines are manufactured in
the U.K. and are type certificated for
operation in the United States under the
provisions of section 21.29 of the
Federal Aviation Regulations (14 CFR
21.29) and the applicable bilateral
airworthiness agreement. Under this
bilateral airworthiness agreement, the
CAA kept the FAA informed of the
situation described above. We have
examined the findings of the CAA,
reviewed all available information, and
determined that AD action is necessary
for products of this type design that are
certificated for operation in the United
States.
FAA’s Determination and Requirements
of This AD
Although no airplanes that are
registered in the United States use these
engines, the possibility exists that the
engines could be used on airplanes that
are registered in the United States in the
future. The unsafe condition described
previously is likely to exist or develop
on other RR RB211 Trent 500 series
turbofan engines of the same type
design. We are issuing this AD to
prevent uncontained release of the HPT
rear side plate and HPT disc, resulting
in damage to the airplane. This AD
requires initial and repetitive borescope
inspections for missing HPT rear seal

plate locking plugs and damaged
locking plug retaining wires. This AD
also requires removing engines from
service based on the number of HPT
locking plugs with acceptable locking
plug retaining wires installed. You must
use the service information described
previously to perform the actions
required by this AD.
FAA’s Determination of the Effective
Date
Since there are currently no domestic
operators of this engine model, notice
and opportunity for public comment
before issuing this AD are unnecessary.
A situation exists that allows the
immediate adoption of this regulation.
Comments Invited
This AD is a final rule that involves
requirements affecting flight safety and
was not preceded by notice and an
opportunity for public comment;
however, we invite you to send us any
written relevant data, views, or
arguments regarding this AD. Send your
comments to an address listed under
ADDRESSES. Include ‘‘AD Docket No.
FAA–2005–23031; Directorate Identifier
2005–NE–41–AD’’ in the subject line of
your comments. We specifically invite
comments on the overall regulatory,
economic, environmental, and energy
aspects of the rule that might suggest a
need to modify it.
We will post all comments we
receive, without change, to https://
dms.dot.gov, including any personal
information you provide. We will also
post a report summarizing each
substantive verbal contact with FAA
personnel concerning this AD. Using the
search function of the DMS Web site,
anyone can find and read the comments
in any of our dockets, including the
name of the individual who sent the
comment (or signed the comment on
behalf of an association, business, labor
union, etc.). You may review the DOT’s
complete Privacy Act Statement in the
Federal Register published on April 11,
2000 (65 FR 19477–78) or you may visit

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 the 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 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.

Turbofan Engines
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain Rolls-Royce plc (RR) RB211 Trent 553-61, 553A2-61, 556-61,
556A2-61, 556B-61, 556B2-61, 560-61, and 560A2-61 turbofan engines.
This AD requires initial and repetitive borescope inspections for
missing HPT rear seal plate locking plugs and damaged locking plug
retaining wires, and removal of the engine from service if necessary,
based on inspection results. This AD results from two reports of
missing HPT rear seal plate locking plugs, damage to the HPT disc, and
damage to the remaining locking plug retaining wires. We are issuing
this AD to prevent uncontained release of the HPT rear side plate and
HPT disc, resulting in damage to the airplane.
DATES: Effective February 16, 2006. The Director of the Federal
Register approved the incorporation by reference of certain
publications listed in the regulations as of February 16, 2006.
We must receive any comments on this AD by April 3, 2006.

SUPPLEMENTARY INFORMATION: The Civil Aviation Authority (CAA), which is
the
[[Page 5163]]
airworthiness authority for the United Kingdom (U.K.), notified us that
an unsafe condition may exist on RR RB211 Trent 500 series turbofan
engines that have not incorporated RR Service Bulletin (SB) No. RB.211-
72-E767. The CAA advises that during shop visit, some engines were
noticed to be missing some of the HPT turbine rear seal plate locking
plugs. This resulted in scoring of the HPT disc rear diaphragm and
impact damage to the remaining locking plug retaining wires, and could
have led to release of the HPT rear seal plate and reduced low-cycle-
fatigue life of the HPT disc.
Relevant Service Information
We have reviewed and approved the technical contents of RR Alert SB
No. RB.211-72-AE358, Revision 3, dated July 13, 2005, that describes
procedures for borescope inspecting the HPT rear seal plate locking
plugs and locking plug retaining wires. The CAA classified this as a
mandatory SB and issued AD G-2005-0007 R1, dated July 11, 2005, in
order to ensure the airworthiness of these RB211 Trent 500 series
turbofan engines in the U.K.
Bilateral Airworthiness Agreement
These RB211 Trent 553-61, 553A2-61, 556-61, 556A2-61, 556B-61,
556B2-61, 560-61, and 560A2-61 series turbofan engines are manufactured
in the U.K. and are type certificated for operation in the United
States under the provisions of section 21.29 of the Federal Aviation
Regulations (14 CFR 21.29) and the applicable bilateral airworthiness
agreement. Under this bilateral airworthiness agreement, the CAA kept
the FAA informed of the situation described above. We have examined the
findings of the CAA, reviewed all available information, and determined
that AD action is necessary for products of this type design that are
certificated for operation in the United States.
FAA's Determination and Requirements of This AD
Although no airplanes that are registered in the United States use
these engines, the possibility exists that the engines could be used on
airplanes that are registered in the United States in the future. The
unsafe condition described previously is likely to exist or develop on
other RR RB211 Trent 500 series turbofan engines of the same type
design. We are issuing this AD to prevent uncontained release of the
HPT rear side plate and HPT disc, resulting in damage to the airplane.
This AD requires initial and repetitive borescope inspections for
missing HPT rear seal plate locking plugs and damaged locking plug
retaining wires. This AD also requires removing engines from service
based on the number of HPT locking plugs with acceptable locking plug
retaining wires installed. You must use the service information
described previously to perform the actions required by this AD.
FAA's Determination of the Effective Date
Since there are currently no domestic operators of this engine
model, notice and opportunity for public comment before issuing this AD
are unnecessary. A situation exists that allows the immediate adoption
of this regulation.
Comments Invited
This AD is a final rule that involves requirements affecting flight
safety and was not preceded by notice and an opportunity for public
comment; however, we invite you to send us any written relevant data,
views, or arguments regarding this AD. Send your comments to an address
listed under ADDRESSES. Include ``AD Docket No. FAA-2005-23031;
Directorate Identifier 2005-NE-41-AD'' in the subject line of your
comments. We specifically invite comments on the overall regulatory,
economic, environmental, and energy aspects of the rule that might
suggest a need to modify it.
We will post all comments we receive, without change, to https://
dms.dot.gov, including any personal information you provide. We will
also post a report summarizing each substantive verbal contact with FAA
personnel concerning this AD. Using the search function of the DMS Web
site, anyone can find and read the comments in any of our dockets,
including the name of the individual who sent the comment (or signed
the comment on behalf of an association, business, labor union, etc.).
You may review the DOT's complete Privacy Act Statement in the Federal
Register published on April 11, 2000 (65 FR 19477-78) or you may visit
https://dms.dot.gov.
Examining the AD Docket
You may examine the docket that contains the AD, any comments
received, and any final disposition in person at the Docket Management
Facility Docket Office 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.
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 the 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 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.
