[Docket No. 98-NM-157-AD; Amendment 39-11114; AD 99-08-08]
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 all Dornier Model 328-100 series airplanes, that requires
repetitive lubrication of the engine control push-pull cables, and
installation of heating tubes on the control cables in the cockpit area
and in the left-hand and right-hand engine balconies, which terminates
the repetitive lubrication requirement. 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 ice from building up on the engine control push-
pull cables, which could result in friction or jamming of the engine
controls, and consequent reduced controllability of the airplane.
DATES: Effective May 17, 1999.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of May 17, 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 all Dornier Model 328-100 series
airplanes was published
[[Page 17513]]
as a supplemental notice of proposed rulemaking (NPRM) in the Federal
Register on January 28, 1999 (64 FR 4370). That action proposed to
require repetitive lubrication of the engine control push-pull cables.
That action also proposed to require the installation of heating tubes
on the control cables in the cockpit area and in the left-hand and
right-hand engine balconies, which would terminate the repetitive
lubrication requirement.
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
The FAA estimates that 50 airplanes of U.S. registry will be
affected by this AD, that it will take approximately 4 work hours per
airplane to accomplish the required lubrication, and that the average
labor rate is $60 per work hour. Based on these figures, the cost
impact on U.S. operators is estimated to be $12,000, or $240 per
airplane.
The FAA estimates that the installation of heating tubes on the
control cables required in this AD action will take approximately 50
work hours per airplane to accomplish, and that the average labor rate
is $60 per work hour. Required parts will be supplied by the
manufacturer at no cost to the operators. Based on these figures, the
cost impact on U.S. operators is estimated to be $150,000, or $3,000
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.
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

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:
99-08-08 Dornier Luftfahrt GMBH: Amendment 39-11114. Docket 98-NM-
157-AD.
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 (c) 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 ice from building up on the engine control push-pull
cables, which could result in friction or jamming of the engine
controls, and consequent reduced controllability of the airplane,
accomplish the following:
(a) Within 2 months after the effective date of this AD,
lubricate the engine control push-pull cables in accordance with
Dornier Alert Service Bulletins ASB-328-76-022, dated December 22,
1997, and ASB-328-76-015, Revision 3, dated January 9, 1998. Repeat
the lubrication thereafter at intervals not to exceed 300 flight
hours until the actions required by paragraph (b) of this AD are
accomplished.
(b) Within 6 months after the effective date of this AD,
accomplish the actions specified in paragraphs (b)(1) and (b)(2) of
this AD. Accomplishment of these actions constitutes terminating
action for the repetitive lubrication requirement of paragraph (a)
of this AD.
(1) Install heating tubes on the control cables in the cockpit
area in accordance with Dornier Service Bulletin SB-328-76-254,
dated June 30, 1998, or Revision 1, dated August 6, 1998.
(2) Install heating tubes on the control cables in the left and
right engine balconies in accordance with Dornier Service Bulletin
SB-328-76-267, Revision 1, dated September 25, 1998, or Revision 2,
dated October 8, 1998.
Alternative Methods of Compliance
(c) 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.
Special Flight Permits
(d) 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.
Incorporation by Reference
(e) The actions shall be done in accordance with Dornier Alert
Service Bulletin ASB-328-76-022, dated December 22, 1997; Dornier
