Airworthiness Directives; Bombardier Model CL-600-2C10 (Regional 
Jet Series 700 and 701) Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: This amendment supersedes an existing airworthiness directive 
(AD), applicable to certain Bombardier Model CL-600-2C10 (Regional Jet 
Series 700 and 701) series airplanes, that currently requires revising 
the Airplane Flight Manual to address uncommanded transfer of fuel 
between the wing fuel tanks and the center fuel tank; revising the 
Minimum Equipment List; limiting airplane operation; and increasing 
normal mission fuel requirements by 3,000 pounds. This amendment 
retains the requirements of the existing AD, and adds requirements for 
modification of the fuel distribution system for the center tank; and 
an inspection of that system for discrepancies, and corrective actions 
if necessary. This amendment is prompted by reports of uncommanded fuel 
transfer between wing fuel tanks and the center fuel tank, and reports 
of misaligned or damaged fuel tubes due to vibration. The actions 
specified in this AD are intended to ensure that the flight crew has 
the procedures necessary to address uncommanded fuel transfer; and to 
detect and correct discrepancies in the fuel distribution system, which 
could cause the center tank to overfill and fuel to leak from the 
center tank vent system or to become inaccessible, and could result in 
engine fuel starvation.

DATES: Effective May 28, 2002.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of May 28, 2002.
    Comments for inclusion in the Rules Docket must be received on or 
before June 12, 2002.

SUPPLEMENTARY INFORMATION: On March 21, 2002, the FAA issued AD 2002-
06-51, amendment 39-12688 (67 FR 14844, March 28, 2002), applicable to 
certain Bombardier Model CL-600-2C10 (Regional Jet Series 700 and 701) 
series airplanes, to require revising the Airplane Flight Manual (AFM) 
to provide procedures for addressing uncommanded transfer of fuel from 
wing fuel tanks to the center fuel tank. That action also requires 
revising the Minimum Equipment List (MEL); limiting operation of the 
airplane to flight within 60 minutes of a suitable alternative airport; 
and ensuring that normal mission fuel requirements are increased by 
3,000 pounds. That action was prompted by reports of uncommanded fuel 
transfer between the wing fuel tanks and the center fuel tank. The 
actions required by that AD are intended to ensure that the flight crew 
has the procedures necessary to address such uncommanded fuel transfer, 
which could cause the center tank to overfill, and fuel to leak from 
the center tank vent system or to become inaccessible, and result in 
engine fuel starvation.

Actions Since Issuance of Previous Rule

    Since the issuance of that AD, Transport Canada Civil Aviation 
(TCCA), which is the airworthiness authority for Canada, has advised 
the FAA that vibration and misalignment of fuel lines in the center 
fuel tank could cause damage to the fuel line couplings, and result in 
leakage of fuel within the center tank. Extensive fuel leakage within 
the center tank could result in an increase in unusable fuel and 
consequent engine fuel starvation.

Explanation of Relevant Service Information

    Bombardier has issued two alert service bulletins to provide 
increased reliability for the fuel system. The procedures included in 
these alert service bulletins are described as follows:
    CRJ700 (Bombardier) Alert Service Bulletin A670BA-28-007, Revision 
B, dated March 18, 2002, specifies procedures for modifying the fuel 
distribution system for the center tank. Modification includes 
installing new brackets and attaching the ejectors with new P-clamps, 
replacing couplings (four in total) with new couplings, and relocating 
certain brackets.
    CRJ700 (Bombardier) Alert Service Bulletin A670BA-28-005, Revision 
B, dated March 21, 2002, specifies procedures for inspection of the 
motive flow line and fuel feed line in the fuel distribution system for 
the center tank to detect discrepancies, and corrective actions if 
necessary. Discrepancies include misalignment, pre-loading, or damage 
to certain parts such as the fuel lines, couplings, boost pump 
canisters, check valves, ejectors, and P-clamps. Corrective actions 
include replacement of any part that exceeds the limit specified by the 
alert service bulletin, and proper alignment of parts.
    TCCA issued Canadian airworthiness directive CF-2002-22, dated 
March 22, 2002, in order to ensure the continued

[[Page 31940]]

airworthiness of these airplanes in Canada.

FAA's Conclusions

    This airplane model is manufactured in Canada 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, TCCA has kept the FAA informed of 
the situation described above. The FAA has examined the findings of 
TCCA, 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.

Explanation of Requirements of Rule

    Since an unsafe condition has been identified that is likely to 
exist or develop on other airplanes of the same type design registered 
in the United States, this AD supersedes AD 2002-06-51 to continue to 
require revising the AFM to address uncommanded transfer of fuel from 
wing fuel tanks to center fuel tank; revising the MEL; limiting 
airplane operation; and increasing normal mission fuel requirements by 
3,000 pounds. This AD adds requirements for modifying the fuel 
distribution system for the center tank; a one-time inspection of the 
motive flow line and fuel feed line in the fuel distribution system for 
discrepancies, and corrective actions if necessary. The actions are 
required to be accomplished per the alert service bulletins described 
previously, except as discussed below.

Differences Between This AD and Canadian Airworthiness Directive

    Operators should note that the applicability of the Canadian 
airworthiness directive specifies serial numbers 10005 through 10039. 
However, this AD expands the applicability to include airplanes having 
serial numbers 10005 and subsequent. The FAA considers that such an 
expansion is necessary until a modification is developed by the 
manufacturer and approved by the FAA to address the identified unsafe 
condition and ensure continued operational safety of the fleet.
    Operators also should note that, although the Canadian 
airworthiness directive specifies that the actions may be accomplished 
per the previously referenced alert service bulletins, ``or later 
revisions,'' this AD requires modification and inspection actions to be 
accomplished per specific alert service bulletins. The FAA points out 
that where a specific service bulletin is referenced in an AD, the use 
of the phrase, ``or later revisions,'' violates Office of the Federal 
Register regulations regarding approval of materials that are 
incorporated by reference.

Difference Between This AD and Canadian Airworthiness Directive/
Alert Service Bulletin

    Operators should note that, although the Canadian airworthiness 
directive and the applicable alert service bulletin specify a ``visual 
inspection,'' this AD specifies a ``detailed inspection.''

Interim Action

    This is considered to be interim action. The manufacturer has 
advised that it currently is developing a modification that will 
positively address the unsafe condition addressed by this AD. Once this 
modification is developed, approved, and available, the FAA may 
consider additional rulemaking.

Clarification of AD 2002-06-51

    Paragraph (a) of this AD has been revised to clarify the reference 
to AD 2002-06-51 by adding ``amendment 39-12688'' following the AD 
number.
    Paragraph (d) of this AD has been revised to clarify the 
operational requirements cited in paragraph (d) of AD 2002-06-51.

Determination of Rule's Effective Date

    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 shall 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.
    Submit comments using the following format:
     Organize comments issue-by-issue. For example, discuss a 
request to change the compliance time and a request to change the 
service bulletin reference as two separate issues.
     For each issue, state what specific change to the AD is 
being requested.
     Include justification (e.g., reasons or data) for each 
request.
    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 
submitted in response to this rule must submit a self-addressed, 
stamped postcard on which the following statement is made: ``Comments 
to Docket Number 2002-NM-99-AD.'' The postcard will be date stamped and 
returned to the commenter.

Regulatory Impact

    The regulations adopted herein 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. Therefore, it 
is determined that this final rule does not have federalism 
implications under Executive Order 13132.
    The FAA has determined that this regulation is an emergency 
regulation that must be issued immediately to correct an unsafe 
condition in aircraft, and that it 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.
