AGENCY:

Federal Aviation Administration, DOT.

ACTION:

Final rule.

SUMMARY:

This amendment adopts a new airworthiness directive (AD), applicable to certain Bombardier Model CL-600-2B19 (Regional Jet Series 440) series airplanes, that requires replacement of the overwing emergency exit placards, door weight placards, and no baggage placards with new placards. This action is necessary 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. This action is intended to address the identified unsafe condition.

DATES:

Effective April 4, 2003.

The incorporation by reference of certain publications listed in the regulations is approved by the Director of the Federal Register as of April 4, 2003.

ADDRESSES:

The service information referenced in this AD may be obtained from Bombardier, Inc., Canadair, Aerospace Group, P.O. Box 6087, Station Centre-ville, Montreal, Quebec H3C 3G9, Canada.

SUPPLEMENTARY INFORMATION:

A proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to include an airworthiness directive (AD) that is applicable to certain Bombardier Model CL-600-2B19 (Regional Jet Series 440) series airplanes was published in the Federal Register on August 7, 2002 (67 FR 51147). That action proposed to require replacement of the overwing emergency exit placards, door weight placards, and no baggage placards with new placards.

Comments

Interested persons have been afforded an opportunity to participate in the making of this amendment. Due consideration has been given to the comments received.Start Printed Page 9510

Requests That Credit Be Given for Previous Replacement

Two commenters request that the FAA revise the notice of proposed rulemaking (NPRM) to specify that replacement accomplished before the effective date of this AD per Bombardier Alert Service Bulletin A601R-11-077, dated July 12, 2001, is considered acceptable for compliance with the replacement specified in paragraph (a) of the NPRM. One commenter states that, with the exception of the pre-modification location of placards for certain airplanes, the changes embodied in Revision “A” of the service bulletin are not significant for the proper execution of the bulletin and, therefore, result in the same level of safety. Another commenter states that Canadian airworthiness directive CF-2002-12, dated February 4, 2002, allows credit for airplanes modified per the original service bulletin.

We agree. We have added a new paragraph (b) in the final rule to provide operators with credit for previously accomplishing Bombardier Alert Service Bulletin A601R-11-077, dated July 12, 2001, and have redesignated the subsequent paragraphs.

Request To Clarify Reference to Attachments

One commenter requests clarification about the attachments specified in paragraph (a) of the NPRM. The commenter states that Bombardier Alert Service Bulletin A601R-11-077, Revision “A,” does not reference “Attachments” within its text. However, the commenter notes that, following page 46 of 46 of the service bulletin, there are two pages—a comment sheet and a compliance sheet. The commenter recommends calling those pages by their given names.

We agree and have revised the names of those sheets in the final rule accordingly. In addition, for clarification purposes, we have changed the service bulletin citation throughout this final rule to exclude those sheets. As stated in the NPRM, this AD does not require operators to complete the comment and compliance sheets.

Explanation of Change to Applicability

We have 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.

Conclusion

After careful review of the available data, including the comments noted above, we have determined that air safety and the public interest require the adoption of the rule with the changes described previously. We have determined that these changes will neither increase the economic burden on any operator nor increase the scope of the AD.

Cost Impact

We estimate that 284 Model CL-600-2B19 (Regional Jet Series 440) series airplanes of U.S. registry will be affected by this AD, that it will take approximately between 1 and 2 hours per airplane depending on the airplane configuration to accomplish the required actions, and that the average labor rate is $60 per work hour. Required parts will cost approximately between $47 and $195 per airplane depending on the configuration of the airplane. Based on these figures, the cost impact of the AD on U.S. operators is estimated to be between $30,388 and $89,460, or $107 and $315 per airplane depending on the configuration of the airplane.

The cost impact figures discussed above are based on assumptions that no operator has yet accomplished any of the requirements of this AD action, and that no operator would accomplish those actions in the future if this AD were not adopted. The cost impact figures discussed in AD rulemaking actions represent only the time necessary to perform the specific actions actually required by the AD. These figures typically do not include incidental costs, such as the time required to gain access and close up, planning time, or time necessitated by other administrative actions. However, for affected airplanes within the period under the warranty agreement, we have been advised that the manufacturer has committed previously to its customers that it will bear the cost of the placard kits.

Regulatory Impact

The regulations adopted herein will not have a substantial direct effect on the States, on the relationship between the national Government and the States, or on the distribution of power and responsibilities among the various levels of government. Therefore, it is determined that this final rule does not have federalism implications under Executive Order 13132.

For the reasons discussed above, I certify that this action (1) is not a “significant regulatory action” under Executive Order 12866; (2) is not a “significant rule” under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and (3) will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. A final evaluation has been prepared for this action and it is contained in the Rules Docket. A copy of it may be obtained from the Rules Docket at the location provided under the caption ADDRESSES.
