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

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule; correction.

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

SUMMARY: This document corrects information in an existing 
airworthiness directive (AD) that applies to certain Bombardier Model 
CL-600-2B19 (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 2003-04-21 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.

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).

FOR FURTHER INFORMATION CONTACT: Dan Parrillo, Aerospace Engineer, 
Systems and Flight Test 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 February 19, 2003, the Federal Aviation 
Administration (FAA) issued AD 2003-04-21, amendment 39-13070 (68 FR 
9509, February 28, 2003), which applies to certain Bombardier Model CL-
600-2B19 (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 2003-04-21 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 
CL-600-2B19 (Regional Jet Series 100 & 440) airplanes.''
    We have determined that a correction to AD 2003-04-21 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 2003-04-21 
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.

Adoption of the Correction

    Accordingly, pursuant to the authority delegated to me by the
