Airworthiness Directives; EXTRA Flugzeugbau GmbH Models EA-300
and EA-300/S Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: This document proposes to adopt a new airworthiness directive
(AD) that would apply to EXTRA Flugzeugbau GmbH (EXTRA) Models EA-300
and EA-300/S airplanes. The proposed AD would require inspecting the
rudder control cables to assure that correctly swaged
Nicopress type sleeves are installed at each end of the
cables, and replacing any cable assembly where correctly swaged
Nicopress type sleeves are not installed. The proposed AD
is the result of mandatory continuing airworthiness information (MCAI)
issued by the airworthiness authority for Germany. The actions
specified by the proposed AD are intended to prevent a control cable
from pulling through an incorrectly swaged sleeve, which could result
in loss of rudder control with consequent loss of control of the
airplane.
DATES: Comments must be received on or before March 10, 1998.
ADDRESSES: Submit comments in triplicate to the Federal Aviation
Administration (FAA), Central Region, Office of the Regional Counsel,
Attention: Rules Docket No. 97-CE-91-AD, Room 1558, 601 E. 12th Street,
Kansas City, Missouri 64106. Comments may be inspected at this location
between 8 a.m. and 4 p.m., Monday through Friday, holidays excepted.
Service information that applies to the proposed AD may be obtained
from EXTRA Flugzeugbau GmbH, Flugplatz Dinslaken, D-4224 Hunxe,
Germany. This information also may be examined at the Rules Docket at

City, Missouri 64106.
Discussion
The Luftfahrt-Bundesamt (LBA), which is the airworthiness authority
for Germany, notified the FAA that an unsafe condition may exist on
EXTRA Models EA-300 and EA-300/S airplanes. The LBA advises of an
incident on one of the affected airplanes where loss of rudder control
was reported. Preliminary investigation reveals that the rudder control
cable pulled through an incorrectly swaged Nicopress type
sleeve.
These conditions, if not detected and corrected, could result in
loss of rudder control with consequent loss of control of the airplane.
Relevant Service Information
EXTRA has issued Service Bulletin No. 300-1-93, dated February 9,
1993, which includes measurements and information for inspecting the
rudder control cables for correctly swaged Nicopress type
sleeves. Procedures for conducting this inspection are included in
Advisory Circular (AC) 43.13-1A, Acceptable Methods, Techniques and
Practices.
The LBA classified EXTRA Service Bulletin No. 300-1-93, dated
February 9, 1993, as mandatory and issued German AD No. 93-081, dated
March 15, 1993, in order to assure the continued airworthiness of these
airplanes in Germany.
The FAA's Determination
This airplane model is manufactured in Germany and is type
certificated for operation in the United States under the provisions of
section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and
the applicable bilateral airworthiness agreement. Pursuant to this
bilateral airworthiness agreement, the LBA has kept the FAA informed of
the situation described above.
The FAA has examined the findings of the LBA; reviewed all
available
[[Page 6690]]
information, including the service information referenced above; and
determined that AD action is necessary for products of this type design
that are certificated for operation in the United States.
Explanation of the Provisions of the Proposed AD
Since an unsafe condition has been identified that is likely to
exist or develop in other EXTRA Models EA-300 and EA-300/S airplanes of
the same type design registered in the United States, the FAA is
proposing AD action. The proposed AD would require inspecting the
rudder control cables to assure that correctly swaged
Nicopress type sleeves are installed at each end of the
cables, and replacing any cable assembly where correctly swaged
Nicopress type sleeves are not installed. Accomplishment of
the proposed inspection would be required in accordance with EXTRA
Service Bulletin No. 300-1-93, dated February 9, 1993, and AC 43.13-1A,
Acceptable Methods, Techniques and Practices. The proposed replacement
would be required in accordance with the maintenance manual.
Cost Impact
The FAA estimates that 23 airplanes in the U.S. registry would be
affected by the proposed AD, that it would take approximately 6
workhours per airplane to accomplish the proposed actions, and that the
average labor rate is approximately $60 an hour. Parts cost
approximately $500 per airplane. Based on these figures, the total cost
impact of the proposed AD on U.S. operators is estimated to be $19,780,
or $860 per airplane.
Regulatory Impact
The regulations proposed herein would 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
proposal would 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) if promulgated,
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 copy of the draft regulatory evaluation
prepared for this action has been placed in the Rules Docket. A copy of
it may be obtained by contacting the Rules Docket at the location
provided under the caption ADDRESSES.
