RIN 2120-AA64


Airworthiness Directives; Dornier Model 328-100 and -300 Series Airplanes


AGENCY:
 
Federal Aviation Administration, DOT.


ACTION:
 
Final rule.


–––––––––––––––––––––––––––––––––––


SUMMARY:
 
This amendment adopts a new airworthiness directive (AD), applicable to certain


Dornier Model 328-100 and -300 series airplanes, that requires replacement of the screws in the


aileron, rudder, and elevator trim tabs with new screws; and removal and re-installation of screws in


the aileron, elevator, and rudder trim tabs and the rudder spring tab; as applicable. This action is


necessary to prevent reduced structural integrity of the screws in the aileron, elevator, and rudder trim


tabs and the rudder spring tab, due to countersinks that were not manufactured correctly, which could


result in reduced controllability of the airplane. This action is intended to address the identified


unsafe condition.


DATES:
 
Effective March 12, 2003.


The incorporation by reference of certain publications listed in the regulations is approved by the


Director of the Federal Register as of March 12, 2003.


ADDRESSES:
 
The service information referenced in this AD may be obtained from FAIRCHILD


DORNIER, DORNIER Luftfahrt GmbH, PO Box 1103, D-82230 Wessling, Germany. 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.

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


Dornier Model 328-100 and -300 series airplanes was published in the Federal Register on September


25, 2002 (67 FR 60193). That action proposed to require replacement of the screws in the aileron,


rudder, and elevator trim tabs with new screws; and removal and re-installation of screws in the


aileron, elevator, and rudder trim tabs and the rudder spring tab; as applicable.


Comments


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.


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 53 Model 328-100 series airplanes and 48 Model 328-300 series


airplanes of U.S. registry will be affected by this AD, that it will take approximately 3 work hours per


airplane to accomplish the required actions, and that the average labor rate is $60 per work hour.


Required parts will be supplied by the manufacturer at no cost to operators. Based on these figures,


the cost impact of the AD on U.S. operators is estimated to be $18,180, or $180 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.
