Discussion

Transport Canada Civil Aviation (TCCA), which is the airworthiness authority for Canada, notified the FAA that an unsafe condition may exist on certain Bombardier Model CL-600-2B19 series airplanes. TCCA advises that the instructions pictured on the overwing emergency exit placards are incorrect. The existing placards show a person opening the overwing emergency exit door in a sitting position, but disposing of it while standing. Due to seat pitch and placement, the overwing emergency exit door can be opened and disposed of only while a person is seated. Incorrect placards on the overwing emergency exit door, if not corrected, could result in the inability of a passenger to open and dispose of the overwing emergency exit door during an emergency evacuation.

Explanation of Relevant Service Information

Bombardier has issued Alert Service Bulletin A601R-11-077, Revision “A,” dated December 11, 2001, including Attachments 1 and 2, which describes procedures for replacement of the overwing emergency exit placards, door weight placards, and no baggage placards with new placards (including cleaning of the applicable surface). Accomplishment of the actions specified in the service bulletin is intended to adequately address the identified unsafe condition. TCCA classified this service bulletin as mandatory and issued Canadian airworthiness directive CF-2002-12, dated February 4, 2002, in order to assure the continued airworthiness of these airplanes in Canada.

FAA's Conclusions

This airplane model is manufactured in Canada and is type certificated for operation in the United States under the provisions of section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness agreement. Pursuant to this bilateral airworthiness agreement, TCCA has kept the FAA informed of the situation described above. The FAA has examined the findings of TCCA, reviewed all available information, and determined that AD action is necessary for products of this type design that are certificated for operation in the United States.

Explanation of Requirements of Proposed Rule

Since an unsafe condition has been identified that is likely to exist or develop on other airplanes of the same type design registered in the United States, the proposed AD would require accomplishment of the action specified in the service bulletin described previously, except as discussed below.

Difference Between Proposed Rule and Referenced Service Bulletin

Operators should note that, although the Accomplishment Instructions of the referenced service bulletin describe procedures for completing a comment sheet related to service bulletin quality and a sheet recording compliance with the service bulletin, this proposed AD would not require those actions. The FAA does not need this information from operators.

Difference Between Proposed Rule and Canadian Airworthiness Directive

The Canadian airworthiness directive requires replacement of the overwing emergency exit placards, door weight placards, and no baggage placards with new placards, per Bombardier Alert Service Bulletin A601R-11-077, Revision ‘A,’ dated December 11, 2001, “or later revision approved by the Director, Aircraft Certification, Transport Canada.” This proposed AD would NOT specify the option of accomplishing the proposed replacement per later approved revisions of the referenced Bombardier service bulletin. The use of the phrase, “or later approved revisions,” violates Office of the Federal Register regulations regarding approval of materials that are incorporated by reference. However, affected operators may request approval to use a later revision of the referenced service bulletin as an alternative method of compliance, under the provisions of paragraph (b) of the proposed AD.

Cost Impact

The FAA estimates that 284 Model CL-600-2B19 series airplanes of U.S. registry would be affected by this proposed AD, that it would take approximately between 1 and 2 hours per airplane depending on the airplane configuration to accomplish the proposed actions, and that the average labor rate is $60 per work hour. Required parts would cost approximately between $47 and $195 Start Printed Page 51149per airplane depending on the configuration of the airplane. Based on these figures, the cost impact of the proposed 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 proposed 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, the FAA has 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 proposed herein would 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 proposal would not have federalism implications under Executive Order 13132.

For the reasons discussed above, I certify that this proposed regulation (1) is not a “significant regulatory action” under Executive Order 12866; (2) is not a “significant rule” under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and (3) if promulgated, 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 copy of the draft regulatory evaluation prepared for this action is contained in the Rules Docket. A copy of it may be obtained by contacting the Rules Docket at the location provided under the caption ADDRESSES.
