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.

ADDRESSES: You can get the service bulletins identified in this AD from 
Rolls-Royce Deutschland Ltd. & Co KG, Eschenweg 11, D-15827 DAHLEWITZ, 
Germany; telephone 49 (0) 33-7086-1768; fax 49 (0) 33-7086-3356.

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.
