14 CFR Part 39
[Docket No. 2003-NM-56-AD; Amendment 39-13674; AD 2004-12-14]
RIN 2120-AA64
Airworthiness Directives; Dornier Model 328-100 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 series airplanes, that
requires an inspection of the alternating current (AC) power cables,
realignment of the AC power cable retaining clamp, and corrective
actions if necessary. This action is necessary to prevent chafing of
the AC power cables against the alternator, which could result in a
short circuit and impaired performance of AC-powered components,
possibly leading to loss of flight-critical information to the flight
deck and reduced controllability of the airplane. This action is
intended to address the identified unsafe condition.
DATES: Effective July 22, 2004.
The incorporation by reference of a certain publication listed in
the regulations is approved by the Director of the Federal Register as
of July 22, 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, 1601 Lind Avenue,
SW., Renton, Washington; or at the National Archives and Records
Administration (NARA). For information on the availability of this

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
series airplanes was published in the Federal Register on April 1, 2004
(69 FR 17086). That action proposed to require an inspection of the
alternating current (AC) power cables, realignment of the AC power
cable retaining clamp, and corrective actions if necessary.
Comments
Interested persons have been afforded an opportunity to participate
in the making of this amendment. No comments have been submitted on the
proposed AD or on the determination of the cost to the public.
Conclusion
After careful review of the available data, the FAA has determined
that air safety and the public interest require the adoption of the
rule as proposed.
Cost Impact
We estimate that 53 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 $65
per work hour. Required parts will cost approximately $122 per
airplane. Based on these figures, the cost impact of the AD on U.S.
operators is estimated to be $16,801, or $317 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
[[Page 33837]]
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

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]

2. Section 39.13 is amended by adding the following new airworthiness
directive:
2004-12-14 Fairchild Dornier GmbH (Formerly Dornier Luftfahrt GmbH):
Amendment 39-13674. Docket 2003-NM-56-AD.
Applicability: Model 328-100 series airplanes, serial numbers
3005 through 3119 inclusive; certificated in any category.
Compliance: Required as indicated, unless accomplished
previously.
To prevent chafing of the alternating current (AC) power cables
against the alternator, which could result in a short circuit and
impaired performance of AC-powered components, possibly leading to
loss of flight-critical information to the flight deck and reduced
controllability of the airplane, accomplish the following:
Corrective Actions
(a) Within 400 flight hours after the effective date of this AD,
perform a general visual inspection of the AC power cables for
damage due to chafing of the cables against the alternator, realign
the cable retaining clamp, repair any damaged cables, install
protective sleeving over the cables, and install cable ties; in
accordance with the Accomplishment Instructions of Dornier Service
Bulletin SB-328-24-433, dated April 12, 2002.
Note 1: For the purposes of this AD, a general visual inspection
is defined as: ``A visual examination of an interior or exterior
area, installation, or assembly to detect obvious damage, failure,
or irregularity. This level of inspection is made from within
touching distance unless otherwise specified. A mirror may be
necessary to enhance visual access to all exposed surfaces in the
inspection area. This level of inspection is made under normally
available lighting conditions such as daylight, hangar lighting,
flashlight, or droplight and may require removal or opening of
access panels or doors. Stands, ladders, or platforms may be
required to gain proximity to the area being checked.''
Alternative Methods of Compliance
(b) In accordance with 14 CFR 39.19, the Manager, International
Branch, ANM-116, FAA, Transport Airplane Directorate, is authorized
to approve alternative methods of compliance for this AD.
