Airworthiness Directives; Bombardier Model CL-600-1A11 (CL-600) 
and CL-600-2A12 (CL-601) Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule; correction.

SUMMARY: This document corrects a typographical error that appeared in 
airworthiness directive (AD) AD 2000-19-01 that was published in the 
Federal Register on September 20, 2000 (65 FR 56780). The typographical 
error resulted in failure to reference an acceptable method of 
compliance for a certain requirement. This AD is applicable to certain 
Bombardier Model CL-600-1A11 (CL-600) and CL-600-2A12 (CL-601) series 
airplanes. This AD requires modification of the main landing gear (MLG) 
brake units and inboard MLG wheels; and a revision to the Airplane 
Flight Manual (AFM) to include the increased cooling times for the 
modified brakes. This AD allows, for certain cases, removal of the 
inboard and/or outboard wheel discs by installation of a placard to 
limit airplane operation on the ground and a revision to the AFM to 
include information for operating the airplane with the wheel discs 
removed. Additionally, this AD provides for an

acceptable method of compliance that involves installation of a new 
revision to the AFM.

DATES: Effective October 25, 2000.

Airframe and Propulsion Branch, ANE-171, FAA, New York Aircraft

SUPPLEMENTARY INFORMATION: Airworthiness Directive (AD) 2000-19-01, 
amendment 39-11902, applicable to certain Bombardier Model CL-600-1A11 
(CL-600) and CL-600-2A12 (CL-601) series airplanes, was published in 
the Federal Register on September 20, 2000 (65 FR 56780). That AD 
requires modification of the main landing gear (MLG) brake units and 
inboard MLG wheels; and a revision to the Airplane Flight Manual (AFM) 
to include the increased cooling times for the modified brakes. That AD 
allows, for certain cases, removal of the inboard and/or outboard wheel 
discs by installation of a placard to limit airplane operation on the 
ground and a revision to the AFM to include information for operating 
the airplane with the wheel discs removed. Additionally, that AD 
provides for an acceptable method of compliance that involves 
installation of a new revision to the AFM.
    As published, paragraph (d) of the existing AD specifies that 
installation of a specific AFM revision is acceptable for compliance 
with the requirements of paragraphs (a) and (b) of that AD. The FAA 
inadvertently did not specify that installation of a specific AFM 
revision is also acceptable for compliance with the requirements of 
paragraph (c) of that AD.
    Since no other part of the regulatory information has been changed, 
the final rule is not being republished.
    The effective date of this AD remains October 25, 2000.
