Airworthiness Directives; Dornier Model 328-100 Series Airplanes

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. 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: Norman B. Martenson, Manager, 
International Branch, ANM-116, FAA, Transport Airplane Directorate, 
1601 Lind Avenue, SW., Renton, Washington 98055-4056; telephone (425) 
227-2110; fax (425) 227-1149.

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.

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.

Adoption of the Amendment

    Accordingly, pursuant to the authority delegated to me by the

the Federal Aviation Regulations (14 CFR part 39) as follows:

PART 39--AIRWORTHINESS DIRECTIVES

    1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec. 39.13  [Amended]

    2. Section 39.13 is amended by removing amendment 39-10854 (63 FR 
57244, October 27, 1998), and by adding a new airworthiness directive 
(AD), amendment 39-12010, to read as follows:

2000-24-03  Dornier Luftfahrt GMBH: Amendment 39-12010. Docket 2000-
NM-112-AD. Supersedes AD 98-22-07, Amendment 39-10854.

    Applicability: All Model 328-100 series airplanes, certificated 
in any category.

    Note 1: 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)(1) 
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 prevent an uncommanded retraction of the flaps during 
takeoff, which could result in an aborted takeoff and consequent 
potential for runway overrun, accomplish the following:
