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 Start Printed Page 59711acceptable method of compliance that involves installation of a new revision to the AFM.

DATES:

Effective October 25, 2000.

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.
