This amendment adopts a new airworthiness directive (AD), applicable to certain BAe Systems (Operations) Limited Model Avro 146-RJ series airplanes, that requires modification of the passenger service units. The actions specified by this AD are intended to prevent failure of the passenger service units to deliver oxygen to the passengers in the event of decompression of the airplane, which could result in injury to the passengers. This action is intended to address the identified unsafe condition.
Effective September 10, 2001.
The incorporation by reference of certain publications listed in the regulations is approved by the Director of the Federal Register as of September 10, 2001.
The service information referenced in this AD may be obtained from British Aerospace Regional Aircraft American Support, 13850 Mclearen Road, Herndon, Virginia 20171. This information may be examined at the Federal Aviation Administration (FAA), Transport Airplane Directorate, Rules Docket, 1601 Lind Avenue, SW., Renton, Washington; or at the Office of the Federal Register, 800 North Capitol Street, NW., suite 700, Washington, DC.Start Further Info

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 BAe Systems (Operations) Limited Model Avro 146-RJ series airplanes was published in the Federal Register on May 1, 2001 (66 FR 21703). That action proposed to require modification of the passenger service units.
Interested persons have been afforded an opportunity to participate in the making of this amendment. No comments have been received.
The FAA has determined that air safety and the public interest require the adoption of the rule as proposed.
The FAA estimates that 40 Model BAe Systems (Operations) Limited Model Avro 146-RJ series airplanes of U.S. registry will be affected by this AD, that it will take approximately 5 work hours per airplane to accomplish the required actions, and that the average labor rate is $60 per work hour. Required parts will be provided at no cost to the operators. Based on these figures, the cost impact of the AD on U.S. operators is estimated to be $12,000, or $300 per airplane.
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
