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 series airplanes was published in the Federal Register on October 30, 2001 (66 FR 54725). That action proposed to require repetitive inspections for cracking of the left and right lower wing planks, and repair, if necessary.
Interested persons have been afforded an opportunity to participate in the making of this amendment. No comments were submitted in response to the proposal or the FAA's determination of the cost to the public.
The FAA has determined that air safety and the public interest require the adoption of the rule as proposed.
This is considered to be interim action until final action is identified, at which time the FAA may consider further rulemaking.
The FAA estimates that 214 airplanes of U.S. registry will be affected by this AD, that it will take approximately 1 work hour per airplane to accomplish the required inspections, and that the average labor rate is $60 per work hour. Based on these figures, the cost impact of the AD on U.S. operators is estimated to be $12,840, or $60 per airplane, per inspection cycle.
The cost impact figure discussed above is 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.
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.Start List of Subjects

1. The authority citation for part 39 continues to read as follows:End Amendment Part Start Printed Page 7605
2. Section 39.13 is amended by adding the following new airworthiness directive:End Amendment Part
2002-03-14 Bombardier, Inc. (Formerly Canadair): Amendment 39-12655. Docket 2001-NM-155-AD.
Applicability: Model CL-600-2B19 series airplanes, serial numbers 7003 through 7999 inclusive, certificated in any category.
This AD applies to each airplane identified in the preceding applicability provision, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. For airplanes that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (d) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.
Compliance: Required as indicated, unless accomplished previously.
To find and fix cracking of the left and right lower wing planks, which could result in reduced structural integrity of the wing, accomplish the following:
(a) Perform an external detailed visual inspection for cracking of the left and right lower wing planks in the area of the rear spar and wing station 148.019, according to Part 2, Accomplishment Instructions, of Bombardier Alert Service Bulletin A601R-57-031, Revision “A,” including Appendix A, dated March 28, 2001. Do the initial inspection at the time shown in paragraph (a)(1), (a)(2), or (a)(3) of this AD, as applicable; and repeat the inspection at least every 5,000 flight cycles.
For the purposes of this AD, a detailed visual inspection is defined as: “An intensive visual examination of a specific structural area, system, installation, or assembly to detect damage, failure, or irregularity. Available lighting is normally supplemented with a direct source of good lighting at intensity deemed appropriate by the inspector. Inspection aids such as mirror, magnifying lenses, etc., may be used. Surface cleaning and elaborate access procedures may be required.”
Compliance Times for Inspection
(1) For airplanes that have accumulated 6,500 total flight cycles or less as of the effective date of this AD: Inspect prior to the accumulation of 7,000 total flight cycles.
