Airworthiness Directives; HOAC-Austria Model DV-20 Katana
Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD) that
applies to certain HOAC-Austria (HOAC) Model DV-20 airplanes equipped
with ROTAX 912 A3 engines. This AD requires replacing the engine
electronic modules. This AD is the result of mandatory continuing
airworthiness information (MCAI) issued by the airworthiness authority
for Austria. The actions specified by this AD are intended to prevent
electromagnetic interference (EMI) on the engine electronic module,
which could cause the airplane engine to stop due to the interruption
of the airplane's ignition system and result in loss of control of the
airplane.
DATES: Effective January 4, 1999.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of January 4, 1999.
ADDRESSES: Service information that applies to this AD may be obtained
from HOAC-Austria, N.A. Otto-StraBe 5, A-2700 Wiener, Neustadt,
Austria. This information may also be examined at the Federal Aviation
Administration (FAA), Central Region, Office of the Regional Counsel,
Attention: Rules Docket No. 97-CE-83-AD, Room 1558, 601 E. 12th Street,
Kansas City, Missouri 64106; or at the Office of the Federal Register,
800 North Capitol Street, NW, suite 700, Washington, DC.
FOR FURTHER INFORMATION CONTACT: Mr. Roger Chudy, Aerospace Engineer,
FAA, Small Airplane Directorate, 1201 Walnut, suite 900, Kansas City,
Missouri 64106; telephone: (816) 426-6934; facsimile: (816) 426-2169.
SUPPLEMENTARY INFORMATION:
Events Leading to the Issuance of This AD
A proposal to amend part 39 of the Federal Aviation Regulations (14
CFR part 39) to include an AD that would apply to certain HOAC Model
DV-20 airplanes equipped with ROTAX 912 A3 engines was published in the
Federal Register as a notice of proposed rulemaking (NPRM) on August
25, 1998 (63 FR 45189). The NPRM proposed to require replacing the
electronic ignition module with one of improved design. Accomplishment
of the proposed action as specified in the NPRM would be in accordance
with Bombardier-ROTAX Technical Bulletin No. 912-08, dated August 16,
1995.
The NPRM was the result of mandatory continuing airworthiness
information (MCAI) issued by the airworthiness authority for Austria.
Interested persons have been afforded an opportunity to participate
in the making of this amendment. No comments were received on the
proposed rule or the FAA's determination of the cost to the public.
The FAA's Determination
After careful review of all available information related to the
subject presented above, the FAA has determined that air safety and the
public interest require the adoption of the rule as proposed except for
minor editorial corrections. The FAA has determined that these minor
corrections will not change the meaning of the AD and will not add any
additional burden upon the public than was already proposed.
Cost Impact
The FAA estimates that 20 airplanes in the U.S. registry will be
affected by this AD, that it will take approximately 1 workhour per
airplane to accomplish this action, and that the average labor rate is
approximately $60 an hour. Parts cost approximately $5,600 per
airplane. Based on these figures, the total cost impact of this AD on
U.S. operators is estimated to be $113,200 or $5,660 per airplane.
The manufacturer has informed the FAA that all of the affected
airplanes registered in the U.S. have accomplished this action,
therefore, the estimated cost impact of this AD on U.S. operators is
eliminated.
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 copy of the final evaluation prepared for this
action is contained in the Rules Docket. A copy of it may be obtained
by contacting the Rules Docket at the location provided under the
caption ADDRESSES.

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 a new airworthiness directive
(AD) to read as follows:
98-24-05 HOAC-Austria: Amendment 39-10891; Docket No. 97-CE-83-AD.
Applicability: Model DV-20 Katana airplanes, certificated in any
category, equipped with ROTAX 912-A3 series engines having serial
numbers 4,076.064 through 4,380.753.
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
[[Page 64603]]
this AD; and, if the unsafe condition has not been eliminated, the
request should include specific proposed actions to address it.
Compliance: Required within the next 100 hours time-in-service
(TIS) after the effective date of this AD, unless already
accomplished.
To prevent electromagnetic interference (EMI) on the engine
electronic module, which could cause the airplane engine to stop due
to the interruption of the airplane's ignition system and result in
loss of control of the airplane, accomplish the following:
(a) Replace the engine electronic module, part number (P/N) 965
356 or an FAA-approved equivalent part number, with a new engine
electronic module, P/N 965 358, in accordance with the Instructions
section of the Bombardier-ROTAX Technical Bulletin No. 912-08, dated
August 16, 1995.
(b) 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.
(c) An alternative method of compliance or adjustment of the
compliance time that provides an equivalent level of safety may be
approved by the Manager, Small Airplane Directorate, Aircraft
Certification Service, 1201 Walnut, suite 900, Kansas City, Missouri
64106. The request shall be forwarded through an appropriate FAA
Maintenance Inspector, who may add comments and then send it to the
Manager, Small Airplane Directorate.
Note 2: Information concerning the existence of approved
alternative methods of compliance with this AD, if any, may be
obtained from the Small Airplane Directorate.
(d) Questions or technical information related to Bombardier-
ROTAX Technical Bulletin No. 912-08, dated August 16, 1995, should
be directed to HOAC-Austria, N.A. Otto-StraBe 5, A-2700 Wiener.
Neustadt, Austria. This service information may be examined at the
FAA, Central Region, Office of the Regional Counsel, Room 1558, 601
E. 12th Street, Kansas City, Missouri.
(e) The replacement required by this AD shall be done in
accordance with Bombardier-ROTAX Technical Bulletin No. 912-08,
dated August 16, 1995. 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 HOAC-Austria,
N.A. Otto-StraBe 5, A-2700 Wiener. Neustadt, Austria. Copies may be
inspected at the FAA, Central Region, Office of the Regional
Counsel, Room 1558, 601 E. 12th Street, Kansas City, Missouri, 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 Austrian AD No.
84, dated October 4, 1995.
(f) This amendment becomes effective on January 4, 1999.
Issued in Kansas City, Missouri, on November 10, 1998.
