00-30120. Airworthiness Directives; Dornier Model 328-100 Series Airplanes  

  • Start Preamble

    AGENCY:

    Federal Aviation Administration, DOT.

    ACTION:

    Final rule.

    SUMMARY:

    This amendment supersedes an existing airworthiness directive (AD), applicable to all Dornier Model 328-100 series airplanes, that currently requires revising the Airplane Flight Manual (AFM) to provide the flightcrew with additional information regarding procedures to ensure complete pressurization of the hydraulic lines for the flaps. This amendment requires revising the existing AFM revision to include a flap system test to be performed prior to the first flight of the day. This amendment also requires, for certain airplanes, modification of the flap actuators of the flight controls. The actions specified by this AD are intended to prevent an uncommanded retraction of the flaps during takeoff, which could result in an aborted takeoff and consequent potential for runway overrun.

    DATES:

    Effective January 8, 2001.

    The incorporation by reference of certain publications, as listed in the regulations, is approved by the Director of the Federal Register as of January 8, 2001.

    The incorporation by reference of Dornier 328 All Operators Telefax AOT-328-27-016, dated July 31, 1998, as listed in the regulations, was approved previously by the Director of the Federal Register as of November 12, 1998 (63 FR 57244, October 27, 1998).

    ADDRESSES:

    The service information referenced in this AD may be obtained from FAIRCHILD DORNIER, DORNIER Luftfahrt GmbH, P.O. Box 1103, D-82230 Wessling, Germany.

    SUPPLEMENTARY INFORMATION:

    A proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) by superseding AD 98-22-07, amendment 39-10854 (63 FR 57244, October 27, 1998), which is applicable to all Dornier Model 328-100 series airplanes, was published in the Federal Register on August 29, 2000 (65 FR 52365). The action proposed to continue to require revising the Airplane Flight Manual (AFM) to provide the flightcrew with additional information regarding procedures to ensure complete pressurization of the hydraulic lines for the flaps. The action also proposed to require revising the existing AFM revision to include a flap system test to be performed prior to the first flight of the day. Additionally, the action proposed to add a requirement, for certain airplanes, for modification of the flap actuators of the flight controls. Start Printed Page 75602

    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

    There are approximately 52 airplanes of U.S. registry that will be affected by this AD.

    The AFM revision that is currently required by AD 98-22-07, and retained in this AD, takes approximately 1 work hour per airplane to accomplish, at an average labor rate of $60 per work hour. Based on these figures, the cost impact of the currently required actions on U.S. operators is approximately $3,120, or $60 per airplane.

    The new AFM revision that is required by this AD will take approximately 1 work hour per airplane to accomplish, at an average labor rate of $60 per work hour. Based on these figures, the cost impact of the required AFM revision on U.S. operators is estimated to be $3,120, or $60 per airplane.

    The new modification that is required by this AD will take approximately 4 work hours per airplane to accomplish, at an average labor rate of $60 per work hour. Required parts will be provided by the manufacturer at no cost to the operators. Based on these figures, the cost impact of the required modification on U.S. operators is estimated to be $240 per airplane.

    The cost impact figures discussed above are 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.
