14 CFR Part 39
[Docket No. 2002-NE-37-AD; Amendment 39-13962; AD 2005-03-06]
RIN 2120-AA64
Airworthiness Directives; Rolls-Royce Deutschland Ltd. & Co KG
(formerly Rolls-Royce plc), Model Tay 611-8, 620-15, 650-15, and 651-54
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 plc) Model Tay 611-8, 620-15, 650-15, and 651-54 turbofan
engines, with low pressure (LP) fuel tube, part number (P/N) JR33021A,
installed. That AD currently requires initial and repetitive
inspections of the LP fuel tubes. This AD requires the same inspections
and adds a requirement to replace the fuel tube with a new design tube,
as mandatory terminating action to the repetitive inspections. This AD
results from the manufacturer introducing a new design fuel tube, which
eliminates the unsafe condition. We are issuing this AD to prevent a
dual-engine flameout due to fuel exhaustion, which could lead to forced
landing and possible damage to the airplane.
DATES: This AD becomes effective March 17, 2005. The Director of the
Federal Register approved the incorporation by reference of certain
publications listed in the regulations as of March 17, 2005.

FOR FURTHER INFORMATION CONTACT: Jason Yang, Aerospace Engineer, Engine
Certification Office, FAA, Engine and Propeller Directorate, 12 New
England Executive Park, Burlington, MA 01803-5299; telephone (781) 238-
7747; fax (781) 238-7199.
SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39
with a proposed airworthiness directive (AD). The proposed AD applies
to RRD Model Tay 611-8, 620-15, 650-15, and 651-54 turbofan engines,
with LP fuel tube, P/N JR33021A, installed. We published the proposed
AD in the Federal Register on June 9, 2004 (69 FR 32285). That action
proposed to require initial and repetitive inspections of LP fuel
tubes, and replacement of the fuel tube with a new design tube as
mandatory terminating action to the repetitive inspections. That
proposed action results from the manufacturer introducing a new design
fuel tube, which eliminates the unsafe condition.
Special Flight Permits Paragraph Removed
Paragraph (g) of the current AD, AD 2003-05-04, contains a
paragraph pertaining to special flight permits. Even though this final
rule does not contain a similar paragraph, we have made no changes with
regard to the use of special flight permits to operate the airplane to
a repair facility to do the work required by this AD. In July 2002, we
published a new part 39 that contains a general authority regarding
special flight permits and airworthiness directives; see Docket No.
FAA-2004-8460, Amendment 39-9474 (69 FR 47998, July 22, 2002). Thus,
when we now supersede ADs we will not include a specific paragraph on
special flight permits unless we want to limit the use of that general
authority granted in section 39.23.
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.
Comments
We provided the public the opportunity to participate in the
development of this AD. We received no comments on the proposal or on
the determination of the cost to the public.
Conclusion
We have carefully reviewed the available data and determined that
air safety and the public interest require adopting the AD as proposed.
Costs of Compliance
There are about 1,300 RRD Model Tay 611-8, 620-15, 650-15, and 651-
54 turbofan engines of the affected design in the worldwide fleet. We
estimate that 1,206 engines installed on airplanes of U.S. registry
would be affected by this AD. We also estimate that it will take about
two work hours per engine to perform the tube inspection, and two work
hours per engine to perform the tube replacement. The average labor
rate is $65 per work hour. Required parts will cost about $1,300 per
engine. Based on these figures, we estimate the total cost of the AD to
U.S. operators to be $1,720,000.
Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I,
[[Page 7015]]
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.
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. Include
``AD Docket No. 2002-NE-37-AD'' in your request.

April 30, 2003. Use the following compliance times:
(1) For fuel tubes with fewer than 4,000 hours TIS on the
effective date of this AD, replace fuel tube within 10 additional
cycles-in-service or before reaching 4,000 hours TIS, whichever
