ACTION:
We propose to supersede
airworthiness directive (AD) 2007–03–
02 for all Rolls-Royce Deutschland
(RRD) Tay 620–15, Tay 650–15, and Tay
651–54 turbofan engines. AD 2007–03–
02 requires an ultrasonic inspection (UI)
of low-pressure (LP) compressor fan
blades for cracks on certain serial
number (S/N) Tay 650–15 engines. AD
2007–03–02 also requires, for all Tay
611–8, 620–15, Tay 650–15, and Tay
651–54 engines, initial and repetitive
UIs of LP compressor fan blades. AD
2007–03–02 also requires, for Tay 650–
15 and Tay 651–54 engines, UIs of LP
compressor fan blades whenever the
blade set is removed from one engine
and installed on a different engine.
Since we issued AD 2007–03–02, we
received a report of an additional engine
failure due to multiple fan blade
separation. This proposed AD would
require additional inspections for the
affected engines and removal of the Tay
611–8 engine from the applicability of
this AD. We are proposing this AD to
prevent failure of the LP compressor fan
blade, engine failure, and damage to the
airplane.
DATES: We must receive comments on
this proposed AD by January 28, 2014.

Discussion
On January 22, 2007, we issued AD
2007–03–02, Amendment 39–14913 (72
FR 3936, January 29, 2007) (‘‘AD 2007–
03–02’’) for certain RRD Tay 611–8 and
Tay 620–15 turbofan engines with LP
compressor module, part number (P/N)
M01100AA or P/N M01100AB,
installed, and Tay 650–15 and Tay 651–
54 turbofan engines with LP compressor
module, P/N M01300AA or P/N
M01300AB, installed. AD 2007–03–02
requires UI of LP compressor fan blades
for cracks on certain S/N Tay 650–15
engines. AD 2007–03–02 also requires,
for all Tay 611–8, 620–15, 620–15/20,
Tay 650–15, Tay 650–15/20, and Tay
651–54 engines, initial and repetitive
UIs of LP compressor fan blades. AD
2007–03–02 also requires, for Tay 650–
15 and Tay 651–54 engines, UIs of LP
compressor fan blades whenever the
blade set is removed from one engine
and installed on a different engine. AD
PO 00000
Frm 00002
Fmt 4702
Sfmt 4702
71533
2007–03–02 resulted from a report that
a set of LP compressor fan blades failed
before reaching the LP compressor fan
blade full published life limit. We
issued AD 2007–03–02 to prevent LP
compressor fan blades from failing due
to blade root cracks, leading to
uncontained engine failure and damage
to the airplane.
Actions Since AD 2007–03–02 Was
Issued
Since we issued AD 2007–03–02, we
received reports of additional engine
failures. Also since we issued AD 2007–
03–02, the European Aviation Safety
Agency issued AD 2013–151R2, dated
September 2, 2013, which requires UI,
and replacement if found cracked, of
affected LP compressor fan blades. Also
since we issued AD 2007–03–02, RRD
issued ANMSB TAY–72–A1442,
Revision 5, dated May 31, 2013 which
removed the Tay 611–8 engine from the
list of applicable engines.
FAA’s Determination
We are proposing this AD because we
evaluated all the relevant information
and determined the unsafe condition
described previously is likely to exist or
develop in other products of the same
type design.
Proposed AD Requirements
This proposed AD requires a UI of LP
compressor fan blades for cracks for all
620–15, Tay 650–15, and Tay 651–54
engines. This proposed AD would also
require accomplishing the actions
specified in the service information
described previously.
Costs of Compliance
We estimate that this proposed AD
would affect about 52 engines installed
on airplanes of U.S. registry. We also
estimate that it would take about 4
hours per engine to remove and inspect
an LP compressor blade set. The average
labor rate is $85 per hour. Prorated parts
life will cost about $11,750 per engine.
Based on these figures, we estimate the
cost of this proposed AD on U.S.
operators to be $628,680.
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
E:\FR\FM\29NOP1.SGM
29NOP1
71534
Federal Register / Vol. 78, No. 230 / Friday, November 29, 2013 / Proposed Rules
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
proposed AD would not have federalism
implications under Executive Order
13132. This proposed AD would 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 proposed 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),
(3) Will not affect intrastate aviation
in Alaska to the extent that it justifies
making a regulatory distinction, and
(4) 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.

Discussion
On January 22, 2007, we issued AD 2007-03-02, Amendment 39-14913
(72 FR 3936, January 29, 2007) (``AD 2007-03-02'') for certain RRD Tay
611-8 and Tay 620-15 turbofan engines with LP compressor module, part
number (P/N) M01100AA or P/N M01100AB, installed, and Tay 650-15 and
Tay 651-54 turbofan engines with LP compressor module, P/N M01300AA or
P/N M01300AB, installed. AD 2007-03-02 requires UI of LP compressor fan
blades for cracks on certain S/N Tay 650-15 engines. AD 2007-03-02 also
requires, for all Tay 611-8, 620-15, 620-15/20, Tay 650-15, Tay 650-15/
20, and Tay 651-54 engines, initial and repetitive UIs of LP compressor
fan blades. AD 2007-03-02 also requires, for Tay 650-15 and Tay 651-54
engines, UIs of LP compressor fan blades whenever the blade set is
removed from one engine and installed on a different engine. AD 2007-
03-02 resulted from a report that a set of LP compressor fan blades
failed before reaching the LP compressor fan blade full published life
limit. We issued AD 2007-03-02 to prevent LP compressor fan blades from
failing due to blade root cracks, leading to uncontained engine failure
and damage to the airplane.
Actions Since AD 2007-03-02 Was Issued
Since we issued AD 2007-03-02, we received reports of additional
engine failures. Also since we issued AD 2007-03-02, the European
Aviation Safety Agency issued AD 2013-151R2, dated September 2, 2013,
which requires UI, and replacement if found cracked, of affected LP
compressor fan blades. Also since we issued AD 2007-03-02, RRD issued
ANMSB TAY-72-A1442, Revision 5, dated May 31, 2013 which removed the
Tay 611-8 engine from the list of applicable engines.
FAA's Determination
We are proposing this AD because we evaluated all the relevant
information and determined the unsafe condition described previously is
likely to exist or develop in other products of the same type design.
Proposed AD Requirements
This proposed AD requires a UI of LP compressor fan blades for
cracks for all 620-15, Tay 650-15, and Tay 651-54 engines. This
proposed AD would also require accomplishing the actions specified in
the service information described previously.
Costs of Compliance
We estimate that this proposed AD would affect about 52 engines
installed on airplanes of U.S. registry. We also estimate that it would
take about 4 hours per engine to remove and inspect an LP compressor
blade set. The average labor rate is $85 per hour. Prorated parts life
will cost about $11,750 per engine. Based on these figures, we estimate
the cost of this proposed AD on U.S. operators to be $628,680.
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
[[Page 71534]]
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 proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 proposed
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),
(3) Will not affect intrastate aviation in Alaska to the extent
that it justifies making a regulatory distinction, and
(4) 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.
List of Subjects in 14 CFR Part 39
