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 for discrepancies of certain engine
control cables, and replacement of the cables with new or serviceable
control cables, if necessary. It also requires modification of the
cable fairleads on the nose rib firewall. Additionally, this amendment
requires modification of the mounting brackets of the control cable
pulleys in the pulley box. 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 chafing of engine control cables, which could cause the
cables to break and result in loss of engine control and consequent
reduced controllability of the airplane.
DATES: Effective May 4, 1998.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of May 4, 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.

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 January 22,
1998 (63 FR 3270). That action proposed to require a one-time
inspection for discrepancies of certain engine control cables, and
replacement of the cables with new or serviceable control cables, if
necessary. That action also proposed to require modification of the
cable fairleads on the nose rib firewall. Additionally, that action
proposed to require modification of the mounting brackets of the
control cable pulleys in the pulley box.
Comments
Interested persons have been afforded an opportunity to participate
in the making of this amendment. Due consideration has been given to
the single comment received.
The commenter supports the proposed rule.
Conclusion
After careful review of the available data, including the comment
noted above, 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 59 Dornier Model 328-100 series airplanes of
U.S. registry will be affected by this AD.
The actions specified in Dornier Service Bulletin SB-328-76-152
will be required to be accomplished on 56 Dornier Model 328-100 series
airplanes of U.S. registry. It will take approximately 4 work hours per
airplane to accomplish the required actions, at an average labor rate
of $60 per work hour. Required parts will be provided by the
manufacturer at no cost to operators. Based on these figures, the cost
impact of this action on the 56 affected U.S.-registered airplanes is
estimated to be $13,440, or $240 per airplane.
The actions specified in Dornier Service Bulletin SB-328-76-168
will be required to be accomplished on 29 Dornier Model 328-100 series
airplanes of U.S. registry. It will take approximately 12 work hours
per airplane to accomplish the required actions, at an average labor
rate of $60 per work hour. Required parts will be
[[Page 15079]]
provided by the manufacturer at no cost to operators. Based on these
figures, the cost impact of this action on the 29 affected U.S.-
registered airplanes is estimated to be $20,880, or $720 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
