RIN 2120-AA64


Airworthiness Directives; Rolls-Royce Deutschland Ltd. & Co KG, 
Model Tay 620-15 and 650-15 Turbofan Engines

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: This amendment adopts a new airworthiness directive (AD) that 
is applicable to Rolls-Royce Deutschland Ltd. & Co KG (RRD), Model Tay 
620-15 and 650-15 turbofan engines. This action requires initial and 
repetitive inspections of certain low pressure (LP) fuel tubes. This 
amendment is prompted by a dual-engine flameout. The actions specified 
in this AD are intended to prevent a dual-engine flameout due to fuel 
exhaustion, which could lead to forced landing and possible damage to 
the airplane.

DATES: Effective December 18, 2002. The incorporation by reference of 
certain publications listed in the rule is approved by the Director of 
the Federal Register as of December 18, 2002.
    Comments for inclusion in the Rules Docket must be received on or 
before February 3, 2003.

ADDRESSES: Submit comments in triplicate to the Federal Aviation 
Administration (FAA), New England Region, Office of the Regional 
Counsel, Attention: Rules Docket No. 2002-NE-37-AD, 12 New England

SUPPLEMENTARY INFORMATION: The Luftfahrt-Bundesamt (LBA), which is the 
airworthiness authority for Germany, recently notified the FAA that an 
unsafe condition may exist on RRD Model Tay 620-15 and 650-15 turbofan 
engines. The LBA advises that there has been a dual-engine flameout on 
a Fokker 100 airplane that resulted in a forced landing and destruction 
of the airplane. The LBA has determined that a leak from the LP fuel 
tube, which connects the LP fuel flowmeter to the high pressure (HP) 
fuel pump, resulted in complete fuel exhaustion and subsequent dual 
engine flameout.

Manufacturer's Service Information

    RRD has issued Service Bulletin (SB) TAY-73-1540, Revision 1, dated 
September 13, 2002, that specifies procedures for inspecting the LP 
fuel tube for fretting. The LBA classified this service bulletin as 
mandatory and issued AD No. 2002-331, dated September 13, 2002, in 
order to assure the airworthiness of these RRD Model Tay 620-15 and 
650-15 turbofan engines in Germany.

Bilateral Airworthiness Agreement

    This engine model is type certificated in Germany, and is type 
certificated for operation in the United States under the provisions of 
section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and 
the applicable bilateral airworthiness agreement. Pursuant to this 
bilateral airworthiness agreement, the LBA has kept the FAA informed of 
the situation described above. The FAA has examined the findings of the 
LBA, reviewed all available information, and determined that AD action 
is necessary for products of this type design that are certificated for 
operation in the United States.

FAA's Determination of an Unsafe Condition and Required Actions

    Since an unsafe condition has been identified that is likely to 
exist or develop on other RRD Model Tay 620-15 and 650-15 turbofan 
engines of the same type design, this AD is being issued to prevent a 
dual-engine flameout due to fuel exhaustion, which could lead to forced 
landing and possible damage to the airplane. This AD requires an 
initial inspection of the LP fuel tube for fretting within 300 hours or 
one month after the effective date of this AD, whichever occurs first, 
and thereafter, repetitive inspections for fretting within 2,000 hours 
time-in-service after the last inspection. The actions must be done in 
accordance with the service bulletin described previously. The 
inspections required by this AD are considered interim action, and 
further rulemaking actions may be taken.

Immediate Adoption of This AD

    Since a situation exists that requires the immediate adoption of 
this regulation, it is found that notice and opportunity for prior 
public comment hereon are impracticable, and that good cause exists for 
making this amendment effective in less than 30 days.

Comments Invited

    Although this action is in the form of a final rule that involves 
requirements affecting flight safety and, thus, was not preceded by 
notice and an opportunity for public comment, comments are invited on 
this rule. Interested persons are invited to comment on this rule by 
submitting such written data, views, or arguments as they may desire. 
Communications should identify the Rules Docket number and be submitted 
in triplicate to the address specified under the caption ADDRESSES. All 
communications received on or before the closing date for comments will 
be considered, and this rule may be amended in light of the comments 
received. Factual information that supports the commenter's ideas and 
suggestions is extremely helpful in evaluating the effectiveness of the 
AD action and determining whether additional rulemaking action would be 
needed.
    Comments are specifically invited on the overall regulatory, 
economic, environmental, and energy aspects of the rule that might 
suggest a need to modify the rule. All comments submitted will be 
available, both before and after the closing date for comments, in the 
Rules Docket for examination by interested persons. A report that 
summarizes each FAA-public contact concerned with the substance of this 
AD will be filed in the Rules Docket.
    Commenters wishing the FAA to acknowledge receipt of their comments

[[Page 71815]]

submitted in response to this action must submit a self-addressed, 
stamped postcard on which the following statement is made: ``Comments 
to Docket Number 2002-NE-37-AD.'' The postcard will be date stamped and 
returned to the commenter.

Regulatory Analysis

    This final rule does not have federalism implications, as defined 
in Executive Order 13132, because it 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. Accordingly, 
the FAA has not consulted with state authorities prior to publication 
of this final rule.
    The FAA has determined that this regulation is an emergency 
regulation that must be issued immediately to correct an unsafe 
condition in aircraft, and is not a ``significant regulatory action'' 
under Executive Order 12866. It has been determined further that this 
action involves an emergency regulation under DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979). If it is determined 
that this emergency regulation otherwise would be significant under DOT 
Regulatory Policies and Procedures, a final regulatory evaluation will 
be prepared and placed in the Rules Docket. A copy of it, if filed, may 
be obtained from the Rules Docket at the location provided under the 
caption ADDRESSES.
