Airworthiness Directives; Bombardier Model CL-600-2B19 Series 
Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: This amendment revises an existing airworthiness directive 
(AD), applicable to certain Bombardier Model CL-600-2B19 series 
airplanes, that currently requires installation of shields for the 
aileron quadrants in the wheel bay of the main landing gear (MLG). This 
amendment revises the compliance time for the requirements of that AD. 
The actions specified in this AD are intended to prevent accumulation 
of

[[Page 61084]]

water, ice, or slush on the aileron quadrants and control cable pulleys 
in the wheel bay of the MLG, which could freeze and result in reduced 
controllability of the airplane.

DATES: Effective October 2, 2000.
    The incorporation by reference of certain publications listed in 
the regulations was approved previously by the Director of the Federal 
Register as of October 2, 2000 (65 FR 57944, September 27, 2000).
    Comments for inclusion in the Rules Docket must be received on or 
before October 23, 2000.

ADDRESSES: Submit comments in triplicate to the Federal Aviation 
Administration (FAA), Transport Airplane Directorate, ANM-114,

FOR FURTHER INFORMATION CONTACT: Daniel Parrillo, Aerospace Engineer, 
Airframe and Propulsion Branch, ANE-172, FAA, New York Aircraft 
Certification Office, 10 Fifth Street, Third Floor, Valley Stream, New 
York 11581; telephone (516) 256-7505; fax (516) 568-2716.

SUPPLEMENTARY INFORMATION: On September 22, 2000, the FAA issued AD 
2000-20-03, amendment 39-11914 (65 FR 57944, September 27, 2000), 
applicable to certain Bombardier Model CL-600-2B19 series airplanes, to 
require installation of shields for the aileron quadrants and control 
cable pulleys in the wheel bay of the main landing gear (MLG). The 
actions required by that AD are intended to prevent accumulation of 
water, ice, or slush on the aileron quadrants and control cable pulleys 
in the wheel bay of the MLG, which could freeze and result in reduced 
controllability of the airplane.

Actions Since Issuance of Previous Rule

    Since the issuance of that AD, the FAA has determined that an 
incorrect compliance time for the installation of the shields was 
inadvertently specified in AD 2000-20-03. Instead of ``within 30 days 
after the effective date of this AD,'' the compliance time should read 
``within 45 days after the effective date of this AD.''

FAA's Findings

    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, Transport Canada Civil Aviation 
(TCAA) has kept the FAA informed of the situation described above. The 
FAA has examined the findings of the TCAA, 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 revises AD 2000-20-03 to require 
installation of shields for the aileron quadrants in the wheel bay of 
the MLG within 45 days after October 2, 2000 (the effective date of AD 
2000-20-03).

Determination of Rule's Effective Date

    Since a situation still 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 still 
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:
    <bullet> 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.
    <bullet> For each issue, state what specific change to the AD is 
being requested.
    <bullet> 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 2000-NM-312-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

[[Page 61085]]

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.
