ACTION: Final rule; request for

AGENCY:
Examining the AD Docket
The FAA is revising an
existing airworthiness directive (AD) for
the products listed above. This AD
revision results from the need to correct
the applicability paragraph of that AD,
and from mandatory continuing
airworthiness information (MCAI)
issued by an aviation authority of
another country to identify and correct
an unsafe condition on an aviation
product. The MCAI describes the unsafe
condition as:
emcdonald on DSK2BSOYB1PROD with RULES
SUMMARY:
Strip results from some of the engines
listed in the applicability section of this AD
revealed excessively corroded low-pressure
turbine disks stage 2 and stage 3. The
corrosion is considered to be caused by the
environment in which these engines are
operated. Following a life assessment based
on the strip findings it is concluded that
inspections for corrosion attack are required.
The action specified by this European
Aviation Safety Agency (EASA) AD 2008–
0122 was intended to avoid a failure of a lowpressure turbine disk stage 2 or stage 3 due
to potential corrosion problems which could
result in uncontained engine failure and
damage to the airplane. It has been later
realized that the same unsafe condition could
potentially occur on more serial numbers for
the Tay 650–15 engines and on the Tay 651–
54 engines. This AD, superseding EASA AD
2008–0122, retaining its requirements, is
therefore issued to expand the Applicability
in adding further engine serial numbers for
the Tay 650–15 engines and in adding the
Tay 651–54 engines.
We are issuing this AD to detect
corrosion that could cause the stage 2 or
stage 3 disk of the LP turbine to fail,
uncontained engine failure, and damage
to the airplane.

SUPPLEMENTARY INFORMATION:
Discussion
On August 23, 2010, we published AD
2010–17–12, Amendment 39–16404, in
the Federal Register (75 FR 51651). That
AD is applicable to RRD models Tay
650–15 and Tay 651–54 turbofan
engines. We discovered that the
applicability paragraph of that AD is in
error. This AD revision corrects that
applicability paragraph. The
requirements of that AD remain the
same in this AD revision.
FAA’s Determination and Requirements
of This AD
This product has been approved by
the aviation authority of the United
PO 00000
Frm 00023
Fmt 4700
Sfmt 4700
67611
Kingdom, and is approved for operation
in the United States. Pursuant to our
bilateral agreement with the United
Kingdom, they have notified us of the
unsafe condition described in the MCAI.
We are issuing this AD because we
evaluated all information provided by
the European Aviation Safety Agency
and determined the unsafe condition
exists and is likely to exist or develop
on other products of the same type
design.
FAA’s Determination of the Effective
Date
An unsafe condition exists that
requires the immediate adoption of this
AD. The FAA has found that the risk to
the flying public justifies waiving notice
and comment prior to adoption of this
rule because this AD revision reduces
the applicability, and the impact on the
affected U.S. registered fleet remains
unchanged. Therefore, we determined
that notice and opportunity for public
comment before issuing this AD are
impracticable and that good cause exists
for making this amendment effective in
fewer than 30 days.
Comments Invited
This AD is a final rule that involves
requirements affecting flight safety, and
we did not precede it by notice and
opportunity for public comment. We
invite you to send any written relevant
data, views, or arguments about this AD.
Send your comments to an address
listed under the ADDRESSES section.
Include ‘‘Docket No. FAA–2007–0037;
Directorate Identifier 2007–NE–41–AD’’
at the beginning of your comments. We
specifically invite comments on the
overall regulatory, economic,
environmental, and energy aspects of
this AD. We will consider all comments
received by the closing date and may
amend this AD because of those
comments.
We will post all comments we
receive, without change, to https://
www.regulations.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 Web site, anyone
can find and read the comments in any
of our dockets, including, if provided,
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

Federal Register / Vol. 75, No. 212 / Wednesday, November 3, 2010 / Rules and Regulations
Authority for This Rulemaking
§ 39.13
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 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 this AD:
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 regulatory evaluation
of the estimated costs to comply with
this AD and placed it in the AD docket.
[Amended]
2. The FAA amends § 39.13 by
removing Amendment 39–16404, and
adding the following new airworthiness
directive (AD):
Affected ADs
(b) This AD revises AD 2010–17–12,

2006, or Revision 2, dated June 13, 2008,
comply with the initial inspection
requirements specified in this AD.
Reason
(d) This AD revision results from:
(1) The need to correct the applicability
paragraph of AD 2010–17–12; and
(2) From mandatory continuing
airworthiness information (MCAI) issued by
an aviation authority of another country to
identify and correct an unsafe condition on
an aviation product. The MCAI states:
(3) Strip results from some of the engines
listed in the applicability section of this AD
revealed excessively corroded low-pressure
turbine disks stage 2 and stage 3. The
corrosion is considered to be caused by the
environment in which these engines are
operated. Following a life assessment based
on the strip findings it is concluded that
inspections for corrosion attack are required.
The action specified by this European
Aviation Safety Agency (EASA) AD 2008–
0122 was intended to avoid a failure of a lowpressure turbine disk stage 2 or stage 3 due
to potential corrosion problems which could
result in uncontained engine failure and
damage to the airplane. It has been later
realized that the same unsafe condition could
potentially occur on more serial numbers for
the Tay 650–15 engines and on the Tay 651–
54 engines. This AD, superseding EASA AD
2008–0122, retaining its requirements, is
therefore issued to expand the Applicability
in adding further engine serial numbers for
the Tay 650–15 engines and in adding the
Tay 651–54 engines.
We are issuing this AD to detect corrosion
that could cause the stage 2 or stage 3 disk
of the LP turbine to fail, uncontained engine
failure, and damage to the airplane.

report of a crack in a propeller hub. We
are issuing this AD to prevent cracked
propeller hubs, which could cause
failure of the propeller hub, blade

SUMMARY: The FAA is revising an existing airworthiness directive (AD)
for the products listed above. This AD revision results from the need
to correct the applicability paragraph of that AD, and from mandatory
continuing airworthiness information (MCAI) issued by an aviation
authority of another country to identify and correct an unsafe
condition on an aviation product. The MCAI describes the unsafe
condition as:
Strip results from some of the engines listed in the
applicability section of this AD revealed excessively corroded low-
pressure turbine disks stage 2 and stage 3. The corrosion is
considered to be caused by the environment in which these engines
are operated. Following a life assessment based on the strip
findings it is concluded that inspections for corrosion attack are
required. The action specified by this European Aviation Safety
Agency (EASA) AD 2008-0122 was intended to avoid a failure of a low-
pressure turbine disk stage 2 or stage 3 due to potential corrosion
problems which could result in uncontained engine failure and damage
to the airplane. It has been later realized that the same unsafe
condition could potentially occur on more serial numbers for the Tay
650-15 engines and on the Tay 651-54 engines. This AD, superseding
EASA AD 2008-0122, retaining its requirements, is therefore issued
to expand the Applicability in adding further engine serial numbers
for the Tay 650-15 engines and in adding the Tay 651-54 engines.

in the Federal Register (75 FR 51651). That AD is applicable to RRD
models Tay 650-15 and Tay 651-54 turbofan engines. We discovered that
the applicability paragraph of that AD is in error. This AD revision
corrects that applicability paragraph. The requirements of that AD
remain the same in this AD revision.
FAA's Determination and Requirements of This AD
This product has been approved by the aviation authority of the
United Kingdom, and is approved for operation in the United States.
Pursuant to our bilateral agreement with the United Kingdom, they have
notified us of the unsafe condition described in the MCAI. We are
issuing this AD because we evaluated all information provided by the
European Aviation Safety Agency and determined the unsafe condition
exists and is likely to exist or develop on other products of the same
type design.
FAA's Determination of the Effective Date
An unsafe condition exists that requires the immediate adoption of
this AD. The FAA has found that the risk to the flying public justifies
waiving notice and comment prior to adoption of this rule because this
AD revision reduces the applicability, and the impact on the affected
U.S. registered fleet remains unchanged. Therefore, we determined that
notice and opportunity for public comment before issuing this AD are
impracticable and that good cause exists for making this amendment
effective in fewer than 30 days.
Comments Invited
This AD is a final rule that involves requirements affecting flight
safety, and we did not precede it by notice and opportunity for public
comment. We invite you to send any written relevant data, views, or
arguments about this AD. Send your comments to an address listed under
the ADDRESSES section. Include ``Docket No. FAA-2007-0037; Directorate
Identifier 2007-NE-41-AD'' at the beginning of your comments. We
specifically invite comments on the overall regulatory, economic,
environmental, and energy aspects of this AD. We will consider all
comments received by the closing date and may amend this AD because of
those comments.
We will post all comments we receive, without change, to https://www.regulations.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
Web site, anyone can find and read the comments in any of our dockets,
including, if provided, 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).

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 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 this AD:
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 regulatory evaluation of the estimated costs to
comply with this AD and placed it in the AD docket.

Reason
(d) This AD revision results from:
(1) The need to correct the applicability paragraph of AD 2010-
17-12; and
(2) From mandatory continuing airworthiness information (MCAI)
issued by an aviation authority of another country to identify and
correct an unsafe condition on an aviation product. The MCAI states:
(3) Strip results from some of the engines listed in the
applicability section of this AD revealed excessively corroded low-
pressure turbine disks stage 2 and stage 3. The corrosion is
considered to be caused by the environment in which these engines
are operated. Following a life assessment based on the strip
findings it is concluded that inspections for corrosion attack are
required. The action specified by this European Aviation Safety
Agency (EASA) AD 2008-0122 was intended to avoid a failure of a low-
pressure turbine disk stage 2 or stage 3 due to potential corrosion
problems which could result in uncontained engine failure and damage
to the airplane. It has been later realized that the same unsafe
condition could potentially occur on more serial numbers for the Tay
650-15 engines and on the Tay 651-54 engines. This AD, superseding
EASA AD 2008-0122, retaining its requirements, is therefore issued
to expand the Applicability in adding further engine serial numbers
for the Tay 650-15 engines and in adding the Tay 651-54 engines.
We are issuing this AD to detect corrosion that could cause the
stage 2 or stage 3 disk of the LP turbine to fail, uncontained
engine failure, and damage to the airplane.
Actions and Compliance
(e) Unless already done, do the following actions.
(1) Prior to accumulating 11,700 flight cycles (FC) since new of
disk life, and thereafter at intervals not exceeding 11,700 FC of
disk life, inspect the LP turbine disks stage 2 and stage 3 for
corrosion using RRD Alert Service Bulletin (ASB) No. TAY-72-A1524,
Revision 3, dated March 24, 2010.
(2) For engines with disk life that already exceed 11,700 FC on
the effective date of this AD, perform the inspection within 90 days
after the effective date of this AD.
(3) When, during any of the inspections as required by
paragraphs (e)(1) and (e)(2) of this AD, corrosion is found, replace
the affected parts. RRD TAY 650 Engine Manual--E-TAY-3RR, Tasks 72-
52-23-200-000 and 72-52-24-200-000, and RRD TAY 651 Engine Manual--
E-TAY-5RR, Tasks 72-52-23-200-000 and 72-52-24-200-000, contain
guidance on performing the inspection for corrosion and rejection
criteria.
Previous Credit
(f) Initial inspections done before the effective date of this
AD on LP turbine disks stage 2 and stage 3 listed in Table 1 and
Table 2 of this AD using RRD ASB No. TAY-72-A1524, Revision 1, dated
September 1, 2006, or Revision 2, dated June 13, 2008, comply with
the initial inspection requirements specified in this AD.
Alternative Methods of Compliance (AMOCs)
(g) The Manager, Engine Certification Office, FAA, has the
authority to approve AMOCs for this AD, if requested using the
procedures found in 14 CFR 39.19.
