14 CFR Part 39
[Docket No. 2003-CE-60-AD; Amendment 39-13591; AD 2004-09-02]
RIN 2120-AA64
Airworthiness Directives; Glasflugel--Ing. E. Hanle Model
GLASFLUGEL Kestrel Sailplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA adopts a new airworthiness directive (AD) for all
Glasflugel--Ing. E. Hanle (Glasflugel) Model GLASFLUGEL Kestrel
sailplanes. This AD requires you to inspect the airbrake actuating
shaft for deformation and cracks (herein referred to as damage). If any
damage is found, this AD also requires you to repair or replace the
airbrake actuation shaft. This AD is the result of mandatory continuing
airworthiness information (MCAI) issued by the airworthiness authority
for Germany. We are issuing this AD to detect and correct damage to the
airbrake actuation shaft, which could result in failure of the airbrake
control. This failure could lead to loss of control of the sailplane.
DATES: This AD becomes effective on June 18, 2004.
As of June 18, 2004, the Director of the Federal Register approved
the incorporation by reference of certain publications listed in the
regulation.

SUPPLEMENTARY INFORMATION:
Discussion
What events have caused this AD? The Lutfahrt-Bundesamt (LBA),
which is the airworthiness authority for Germany, recently notified FAA
that an unsafe condition may exist on all Glasflugel Model GLASFLUGEL
Kestrel sailplanes. The LBA reports that, on one of the affected
sailplanes, the airbrakes would not completely open or close.
A visual inspection of that sailplane revealed cracks and deformity
(damage) on the airbrake actuating shaft. Incorrect locking forces of
the airbrake control caused the damage.
What is the potential impact if FAA took no action? If not detected
and corrected, damage to the airbrake actuating shaft could result in
failure of airbrake control. This failure could lead to loss of control
of the sailplane.
Has FAA taken any action to this point? We issued a proposal to
amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to
include an AD that would apply to all Glasflugel Model GLASFLUGEL
Kestrel sailplanes. This proposal was published in the Federal Register
as a notice of proposed rulemaking (NPRM) on February 5, 2004 (69 FR
5477). The NPRM proposed to require you to:
--Inspect the airbrake actuation shaft for damage; and
--Repair or replace any damaged airbrake actuation shaft.
Comments
Was the public invited to comment? We provided the public the
opportunity to participate in developing this AD. We received no
comments on the proposal or on the determination of the cost to the
public.
Conclusion
What is FAA's final determination on this issue? We have carefully
reviewed the available data and determined that air safety and the
public interest require adopting the AD as proposed except for minor
editorial corrections. We have determined that these minor corrections:
--Are consistent with the intent that was proposed in the NPRM for
correcting the unsafe condition; and
--Do not add any additional burden upon the public than was already
proposed in the NPRM.
Changes to 14 CFR Part 39--Effect on the AD
How does the revision to 14 CFR part 39 affect this AD? On July 10,
2002, the FAA published a new version of 14 CFR part 39 (67 FR 47997,
July 22, 2002), which governs the FAA's AD system. This regulation now
includes material that relates to altered products, special flight
permits, and alternative methods of compliance. This material
previously was included in each individual AD. Since this material is
included in 14 CFR part 39, we will not include it in future AD
actions.
Costs of Compliance
How many sailplanes does this AD impact? We estimate that this AD
affects 16 sailplanes in the U.S. registry.
What is the cost impact of this AD on owners/operators of the
affected sailplanes? We estimate the following costs to accomplish the
inspection:
----------------------------------------------------------------------------------------------------------------
Total cost per Total cost on U.S.
Labor cost Parts cost sailplane operators
----------------------------------------------------------------------------------------------------------------
1 workhour x $65 per hour = $65... Not applicable.................... $65 $65 x 16 = $1,040
----------------------------------------------------------------------------------------------------------------
[[Page 25480]]
We estimate the following costs to accomplish any necessary repairs
or replacements that will be required based on the results of the
inspection. We have no way of determining the number of sailplanes that
may need this repair or replacement:
------------------------------------------------------------------------
Total cost per
Labor cost Parts cost sailplane
------------------------------------------------------------------------
5 workhours x $65 per hour = $325.... $40 $325 + $40 = $365
------------------------------------------------------------------------
Regulatory Findings
Will this AD impact various entities? We have determined that this
AD will not have federalism implications under Executive Order 13132.
This AD will not have a substantial direct effect 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.
Will this AD involve a significant rule or regulatory action? For
the reasons discussed above, I certify that this AD:
1. Is not a ``significant regulatory action'' under Executive Order
12866;
2. Is not a ``significant rule'' under the 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.
We prepared a summary of the costs to comply with this AD and
placed it in the AD Docket. You may get a copy of this summary by
sending a request to us at the address listed under ADDRESSES. Include
``AD Docket No. 2003-CE-60-AD'' in your request.
