2014-06-05 ROLLS-ROYCE DEUTSCHLAND LTD & CO KG (TYPE CERTIFICATE PREVIOUSLY HELD BY ROLLS-ROYCE PLC): Amendment 39-17809; Docket No. FAA-2006-24777; Directorate Identifier 2006-NE-19-AD.
TDATA NOTE: The Summary is included here  to  identify  the removal of the
            TAY 611-8 engine from the applicability.

SUMMARY: We  are superseding  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 required 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 required, 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 required, 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.
This  AD  requires additional  inspections  for the  affected  engines and
removal  of  the  Tay 611-8 engine from  the applicability.  This  AD  was
prompted by a report of an  additional engine failure due to multiple  fan
blade separation.  We are  issuing this  AD to  prevent failure  of the LP
compressor fan blade, engine failure, and damage to the airplane.

(a) EFFECTIVE DATE

    This AD is effective May 8, 2014.

(b) AFFECTED ADS

    This  AD supersedes  AD 2007-03-02,  Amendment 39-14913  (72 FR  3936,
    January 29, 2007).

(c) APPLICABILITY

    This AD applies to  Rolls-Royce Deutschland  Ltd & Co KG (RRD) Tay 620
    -15 turbofan  engines with  low-pressure (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.

(d) UNSAFE CONDITION

    This AD was prompted by a  report of an additional engine failure  due
    to multiple fan  blade separation. We  are issuing this  AD to prevent
    failure of the LP compressor fan blade, engine failure, and damage  to
    the airplane.

(e) COMPLIANCE

PREAMBLE 

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

SUMMARY: We are superseding 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 required 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 required,
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
required, 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. This AD requires additional
inspections for the affected engines and removal of the Tay 611-8
engine from the applicability. This AD was prompted by a report of an
additional engine failure due to multiple fan blade separation. We are
issuing this AD to prevent failure of the LP compressor fan blade,
engine failure, and damage to the airplane.

SUPPLEMENTARY INFORMATION:

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2007-03-02, Amendment 39-14913 (72 FR 3936,
January 29, 2007), (``AD 2007-03-02''). AD 2007-03-02 applied to all
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. The NPRM published in the Federal
Register on November 29, 2013 (78 FR 71532). The NPRM proposed to
require a UI of LP compressor fan blades for cracks on certain S/N Tay
650-15 engines; initial and repetitive UIs of LP compressor fan blades
for all Tay 620-15, Tay 650-15, and Tay 651-54 engines; and UIs of LP
compressor fan blades whenever the blade set is removed from one engine
and installed on a different engine for Tay 650-15 and Tay 651-54
engines. The NPRM also proposed to require additional inspections for
the affected engines and removal of the Tay 611-8 engine from the
applicability of this AD.

Comments

We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (78 FR 71532, November 29,
2013).

Conclusion

We reviewed the relevant data and determined that air safety and
the public interest require adopting this AD as proposed.

Costs of Compliance

We estimate that this AD affects about 52 engines installed on
airplanes of U.S. registry. We also estimate that it will 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 that the cost
of this AD on U.S. operators is $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 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

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),
(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

Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.

Adoption of the Amendment

Accordingly, under the authority delegated to me by the
Administrator, the FAA amends part 39 of the Federal Aviation
Regulations (14 CFR part 39) as follows:

PART 39--AIRWORTHINESS DIRECTIVES

1. The authority citation for part 39 continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

Sec. 39.13 [Amended]

2. The FAA amends Sec. 39.13 by removing airworthiness directive (AD)
2007-03-02, Amendment 39-14913 (72 FR 3936, January 29, 2007) and
adding the following new AD:
