[Docket No. 98-NM-290-AD; Amendment 39-10953; AD 98-26-12]
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 a one-time inspection to verify correct installation of the
lockplates of the roll spoiler actuators, and corrective actions, if
necessary. This amendment is prompted by issuance of mandatory
continuing airworthiness information by a foreign civil airworthiness
authority. The actions specified by this AD are intended to prevent
fatigue cracking of the fork flanges of the roll spoiler actuators due
to incorrect installation of the lockplates, which could result in
reduced structural integrity of the components of the roll spoiler
actuators, and consequent reduced controllability of the airplane.
DATES: Effective January 25, 1999.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of January 25, 1999.
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.

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 October 27,
1998 (63 FR 57258). That action proposed to require a one-time
inspection to verify correct installation of the lockplates of the roll
spoiler actuators, and corrective actions, if necessary.
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.
[[Page 70322]]
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 50 airplanes of U.S. registry will be
affected by this AD, that it will take approximately 1 work hour per
airplane to accomplish the required inspection, and that the average
labor rate is $60 per work hour. Based on these figures, the cost
impact of the AD on U.S. operators is estimated to be $3,000, or $60
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.
Regulatory Impact
The regulations adopted herein will not have substantial direct
effects 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, in
accordance with Executive Order 12612, it is determined that this final
rule does not have sufficient federalism implications to warrant the
preparation of a Federalism Assessment.
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

reference, Safety.
Adoption of the Amendment
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
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:
98-26-12 Dornier Luftfahrt GMBH: Amendment 39-10953. Docket 98-NM-
290-AD.
Applicability: Model 328-100 series airplanes, serial numbers
3005 through 3095 inclusive; 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 (b) 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 fatigue cracking of the fork flanges of the roll
spoiler actuators due to incorrect installation of the lockplates,
which could result in reduced structural integrity of the components
of the roll spoiler actuators, and consequent reduced
controllability of the airplane, accomplish the following:
(a) Within 300 flight hours after the effective date of this AD,
perform a one-time visual inspection to verify correct installation
of the lockplates of the roll spoiler actuators, in accordance with
Dornier Service Bulletin SB-328-27-263, dated June 29, 1998.
(1) If all lockplates of the roll spoiler actuators are
correctly installed, no further action is required by this AD.
(2) If any lockplate of any roll spoiler actuator is installed
incorrectly, prior to further flight, perform either an eddy current
or dye penetrant inspection to detect cracks of the area surrounding
the fork flanges of the roll spoiler actuators, in accordance with
the service bulletin.
(i) If no crack is detected, no further action is required by
this AD.
(ii) If any crack is detected, prior to further flight, replace
the roll spoiler actuator with a new or serviceable roll spoiler
actuator in accordance with the service bulletin.
(b) An alternative method of compliance or adjustment of the
compliance time that provides an acceptable level of safety may be
used if approved by the Manager, International Branch, ANM-116, FAA,
Transport Airplane Directorate. Operators shall submit their
requests through an appropriate FAA Principal Maintenance Inspector,
who may add comments and then send it to the Manager, International
Branch, ANM-116.
Note 2: Information concerning the existence of approved
alternative methods of compliance with this AD, if any, may be
obtained from the International Branch, ANM-116.
(c) Special flight permits may be issued in accordance with
sections 21.197 and 21.199 of the Federal Aviation Regulations (14
CFR 21.197 and 21.199) to operate the airplane to a location where
the requirements of this AD can be accomplished.
(d) The inspection and replacement shall be done in accordance
with Dornier Service Bulletin SB-328-27-263, dated June 29, 1998.
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 FAIRCHILD DORNIER, DORNIER Luftfahrt
GmbH, P.O. Box 1103, D-82230 Wessling, Germany. Copies may be
inspected at the FAA, Transport Airplane Directorate, 1601 Lind
Avenue, SW., Renton, Washington; or at the Office of the Federal
Register, 800 North Capitol Street, NW., suite 700, Washington, DC.
Note 3: The subject of this AD is addressed in German
airworthiness directive 1998-358, dated September 10, 1998.
(e) This amendment becomes effective on January 25, 1999.
Issued in Renton, Washington, on December 14, 1998.
