Docket ID: [Docket No. 2002-NM-100-AD; Amendment 39-13070; AD 2003-04-21 R1]

RIN ID: RIN 2120-AA64

NOTICE: RULES

ACTION: Airworthiness directives:

DOCUMENT ACTION: Final rule; correction.

SUBJECT CATEGORY: Airworthiness Directives; Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) Airplanes

DATES: Effective April 4, 2003.

The incorporation by reference of a certain publication, as listed in the regulations, was approved previously by the Director of the Federal Register as of April 4, 2003 (68 FR 9509, February 28, 2003).

DOCUMENT SUMMARY: This document corrects information in an existing airworthiness directive (AD) that applies to certain Bombardier Model CL6002B19 (Regional Jet Series 440) series airplanes. That AD currently requires replacement of the overwing emergency exit placards, door weight placards, and no baggage placards with new placards. This document corrects the applicability of AD 20030421 to identify affected model designations as published in the most recent type certificate data sheet. This correction is necessary to ensure that operators of all affected airplanes accomplish the requirements of this AD.

SUMMARY: Bombardier,

SUPPLEMENTAL INFORMATION

On February 19, 2003, the Federal Aviation Administration (FAA) issued AD 20030421, amendment 3913070 (68 FR 9509, February 28, 2003), which applies to certain Bombardier Model CL 6002B19 (Regional Jet Series 440) series airplanes. That AD requires replacement of the overwing emergency exit placards, door weight placards, and no baggage placards with new placards. That AD was prompted by the issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions required by that AD are intended to prevent the inability of a passenger to open and dispose of the overwing emergency exit door during an emergency evacuation due to incorrect placards.

Need for the Correction

In the preamble of AD 20030421 under the heading ``Explanation of Change to Applicability,'' it states, ``[The FAA has] revised the applicability of the final rule to identify model designations as published in the most recent type certificate data sheet for the affected models.'' We revised the applicability of the final rule to include the parenthetical ``(Regional Jet Series 440).'' However, we inadvertently omitted Regional Jet Series ``100,'' which is specified on the type certificate data sheet. In addition, both of these airplane models were identified by serial numbers in the applicability. Therefore, the correct applicability of this AD is ``Bombardier Model CL6002B19 (Regional Jet Series 100 & 440) airplanes.''

We have determined that a correction to AD 20030421 is necessary. We have clarified the applicability of this AD by identifying the affected model designations as published in the most recent type certificate data sheet.

Correction of Publication

This document corrects the error and correctly adds the AD as an amendment to section 39.13 of the Federal Aviation Regulations (14 CFR 39.13).

The AD is reprinted in its entirety for the convenience of affected operators. The effective date of the AD remains April 4, 2003.

Since this action only corrects the applicability of AD 20030421 to identify affected model designations as published in the most recent type certificate data sheet, it has no adverse economic impact and imposes no additional burden on any person. Therefore, the FAA has determined that notice and public procedures are unnecessary. List of Subjects in 14 CFR Part 39
