AD 2003-04-21 R1

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).

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.

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.

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.

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.

Accordingly, pursuant to the authority delegated to me by the Administrator, the Federal Aviation Administration amends part 39 of the Federal Aviation Regulations (14 CFR part 39) as follows:
