DEPARTMENT OF TRANSPORTATION
14 CFR Part 39
[Docket No. 94-CE-36-AD; Amendment 39-9360; AD 95-18-13]
Airworthiness Directives; HOAC AUSTRIA GmbH HK 36R ``Super
Dimona'' Gliders
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD) that
applies to certain HOAC AUSTRIA GmbH (HOAC) HK 36R ``Super Dimona''
gliders. This action requires inspecting the exhaust system for
corrosion, replacing the exhaust system if corrosion is found, and
installing a carbon monoxide detector. Reports received by the Federal
Aviation Administration (FAA) of severe exhaust system corrosion on the
affected gliders, including one of excessive corrosion (rusting
through), prompted this action. The actions specified by this AD are
intended to prevent carbon monoxide leakage caused by a corroded
exhaust system, which, if not detected and corrected, could lead to
passenger injuries.
DATES: Effective October 26, 1995.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of October 26, 1995.
ADDRESSES: Service information that applies to this AD may be obtained
from HOAC AUSTRIA GmbH, N.A. Otto Strasse 5, A-2700 Wiener Neustadt,
Austria. This information may also be examined at the FAA, Central
Region, Office of the Assistant Chief Counsel, Attention: Rules Docket
94-CE-36-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. Herman C. Belderok, Project
Officer, Gliders, Small Airplane Directorate, Aircraft Certification
Service, FAA, 1201 Walnut, suite 900, Kansas City, Missouri 64106;
telephone (816) 426-6932; facsimile (816) 426-2169.
SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal
[[Page 47683]]
Aviation Regulations (14 CFR part 39) to include an AD that would apply
to HOAC HK 36R ``Super Dimona'' gliders was published in the Federal
Register on March 30, 1995 (60 FR 16396). The action proposed to
require inspecting the exhaust system for corrosion, replacing the
exhaust system if corrosion is found, and installing a carbon monoxide
detector. Accomplishment of the proposed action would be in accordance
with the Measures section of HOAC Service Bulletin No. 33, dated July
15, 1993.
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.
After careful review of all available information related to the
subject presented above including the referenced service information,
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.
The FAA estimates that 4 gliders in the U.S. registry will be
affected by this AD, that it will take approximately 1 workhour per
glider to accomplish the required inspection and install a carbon
monoxide detector, and that the average labor rate is approximately $60
an hour. Parts (a carbon monoxide detector) will be provided by the
manufacturer at no cost to the owner/operator. Based on these figures,
the total cost impact of this AD on U.S. operators is estimated to be
$240 ($60 per glider). This figure is based on the assumption that no
affected owner/operator of the affected gliders has incorporated the
required installation or accomplished the required inspection.
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 USC 106(g), 40101, 40113, 44701.
Sec. 39.13 [Amended]
2. Section 39.13 is amended by adding a new airworthiness directive
to read as follows:
95-18-13 HOAC AUSTRIA GmbH: Amendment 39-9360; Docket No. 94-CE-36-
AD.
Applicability: HK 36R ``Super Dimona'' gliders (serial numbers
36.302 through 36.323), certificated in any category.
Note 1: This AD applies to each airplane identified in the
preceding applicability revision, 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 (d) 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 within the next 10 hours time-in-service
after the effective date of this AD, unless already accomplished.
To prevent carbon monoxide leakage caused by a corroded exhaust
system, which, if not detected and corrected, could lead to
passenger injuries, accomplish the following:
(a) Inspect the exhaust system for corrosion in accordance with
the Measures section of HOAC Service Bulletin (SB) No. 33, dated
July 15, 1993. If corrosion is found, prior to further flight,
replace the exhaust system in accordance with the Measures section
of HOAC SB No. 33, dated July 15, 1993.
(b) Install a carbon monoxide detector in accordance with the
Measures section of HOAC SB No. 33, dated July 15, 1993.
(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 glider to a location where the
requirements of this AD can be accomplished.
(d) 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, FAA, 1201
Walnut, suite 900, Kansas City, Missouri 64106. The request should
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.
(e) The inspection, replacement, and installation required by
this AD shall be done in accordance with HOAC Service Bulletin No.
33, dated July 15, 1993. 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 GmbH, N.A. Otto Strasse 5, A-2700 Wiener Neustadt, Austria.
Copies may be inspected at the FAA, Central Region, Office of the
Assistant Chief Counsel, Room 1558, 601 E. 12th Street, Kansas City,
Missouri, or at the Office of the Federal Register, 800 North
Capitol Street, NW., 7th Floor, suite 700, Washington, DC.
(f) This amendment (39-9360) becomes effective on October 26,
1995. Issued in Kansas City, Missouri, on August 28, 1995.
