AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD),
applicable to all Dornier Model 328-100 and -300 series airplanes, that
requires repetitive inspections of the bearing lugs of the rudder
spring tab lever assembly for cracking, and corrective action if
necessary. This action is necessary to prevent failure of the rudder
flight control system due to such cracking, which could result in loss
of rudder control and consequent reduced controllability of the
airplane. This action is intended to address the identified unsafe
condition.
DATES: Effective June 9, 2004.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of June 9, 2004.
ADDRESSES: The service information referenced in this AD may be
obtained from AvCraft Aerospace 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 National Archives
and Records Administration (NARA). For information on the availability

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 all Dornier Model 328-100 and -300
series airplanes was published in the Federal Register on March 5, 2004
(69 FR 10381). That action proposed to require repetitive inspections
of the bearing lugs of the rudder spring tab lever assembly for
cracking, and corrective action if necessary.
Comments
We provided the public the opportunity to participate in the
development of this AD. No comments have been submitted on the proposed
AD or on the determination of the cost to the public.
Conclusion
We have carefully reviewed the available data and determined that
air safety and the public interest require adopting the AD as proposed.
Cost Impact
We estimate that 112 airplanes of U.S. registry will be affected by
this AD, that it will take about 1 work hour per airplane to do the
inspections, and that the average labor rate is $65 per work hour.
Based on these figures, the cost impact of the AD on U.S. operators is
estimated to be $7,280, or $65 per airplane, per inspection cycle.
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.
[[Page 24954]]
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

Adoption of the Amendment
0
Accordingly, pursuant to the authority delegated to me by the
Administrator, the Federal Aviation Administration amends part 39 of
the Federal Aviation Regulations (14 CFR part 39) as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
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]
0
2. Section 39.13 is amended by adding the following new airworthiness
directive:
2004-09-16 Fairchild Dornier GmbH (Formerly Dornier Luftfahrt GmbH):
Amendment 39-13605. Docket 200-NM-263-AD.
Applicability: All Model 328-100 and -300 series airplanes,
certificated in any category.
Compliance: Required as indicated, unless accomplished
previously.
To prevent failure of the rudder flight control system due to
cracking of the bearing lugs of the rudder spring tab lever
assembly, which could result in loss of rudder control and
consequent reduced controllability of the airplane, accomplish the
following:
Repetitive Inspections
(a) Within 400 flight hours or 2 months after the effective date
of this AD, whichever is first: Do detailed and eddy current
inspections for cracking of the bearing lugs of the rudder spring
tab lever assembly by doing all the actions per Paragraphs 2.A.,
2.B., and 2.D. of the Accomplishment Instructions of Dornier Alert
Service Bulletin ASB-328-27-036 (for Model 328-100 series
airplanes); or ASB-328J-27-013 (for Model 328-300 series airplanes);
both dated February 12, 2003; as applicable. If no cracking is
found, repeat the inspections thereafter at intervals not to exceed
24 months.
Note 1: For the purposes of this AD, a detailed inspection is
defined as: ``An intensive visual examination of a specific
structural area, system, installation, or assembly to detect damage,
failure, or irregularity. Available lighting is normally
supplemented with a direct source of good lighting at intensity
deemed appropriate by the inspector. Inspection aids such as mirror,
magnifying lenses, etc., may be used. Surface cleaning and elaborate
access procedures may be required.''
Corrective Action/Repetitive Inspections
(b) If any cracking is found during any inspection required by
paragraph (a) of this AD: Before further flight, replace the spring
tab lever assembly with a new assembly by doing all the actions per
Paragraph 2.C. of the Accomplishment Instructions of Dornier Alert
Service Bulletin ASB-328-27-036; or ASB-328J-27-013, both dated
February 12, 2003; as applicable. Repeat the inspections required by
paragraph (a) of this AD thereafter at intervals not to exceed 24
months.
(c) Dornier Alert Service Bulletins ASB-328-27-036 and ASB-328J-
27-013, both dated February 12, 2003, recommend reporting crack
findings and returning damaged lever assemblies to the manufacturer,
but this AD does not contain such requirements.
Note 2: There is no terminating action available at this time
for the repetitive inspections required by this AD.
Alternative Methods of Compliance
(d) In accordance with 14 CFR 39.19, the Manager, International
Branch, FAA, ANM-116, Transport Airplane Directorate, is authorized
to approve alternative methods of compliance for this AD.
Incorporation by Reference
(e) The actions shall be done in accordance with Dornier Alert
Service Bulletin ASB-328-27-036, dated February 12, 2003; or Dornier
Alert Service Bulletin ASB-328J-27-013, dated February 12, 2003; as
applicable. This incorporation by reference was approved by the
Director of the Federal Register in accordance with 5 U.S.C. 552(a)
and 1 CFR part 51. Copies may be obtained from AvCraft Aerospace
GmbH, P.O. Box 1103, D-82230 Wessling, Germany. Copies may be
