Airworthiness Directives; BAe Systems (Operations) Limited Model 
Avro 146-RJ Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: 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.

DATES: 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.

ADDRESSES: 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.

FOR FURTHER INFORMATION CONTACT: Dan Rodina, Aerospace Engineer, 
International Branch, ANM-116, FAA, Transport Airplane Directorate, 
1601 Lind Avenue, SW., Renton, Washington 98055-4056; telephone (425) 
227-2125; fax (425) 227-1149.

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 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.

Comments

    Interested persons have been afforded an opportunity to participate 
in the making of this amendment. No comments have been received.

Conclusion

    The FAA has determined that air safety and the public interest 
require the adoption of the rule as proposed.

Cost Impact

    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.

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.
