14 CFR Part 39

[Docket No. FAA-2006-24255; Directorate Identifier 2006-CE-25-AD;
Amendment 39-14720; AD 2006-16-20]
RIN 2120-AA64

Airworthiness Directives; DG Flugzeugbau GmbH Model DG-1000S
Sailplanes

AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for all DG
Flugzeugbau GmbH Model DG-1000S sailplanes. This AD requires you to
modify the elevator control at the stabilizer assembly, replace a
placard on the fin, and incorporate changes in the FAA-approved
sailplane flight manual (SFM). This AD results from mandatory
continuing airworthiness information (MCAI) issued by the airworthiness
authority for Germany. We are issuing this AD to prevent the rigging of
the horizontal stabilizer without properly connecting the elevator,
which, if not prevented, could lead to an inoperative elevator. An
inoperative elevator could lead to loss of control of the sailplane.

DATES: This AD becomes effective on September 18, 2006.
As of September 18, 2006, the Director of the Federal Register
approved the incorporation by reference of certain publications listed
in the regulation.

ADDRESSES: For service information identified in this AD, contact DG-

SUPPLEMENTARY INFORMATION:

Discussion

On May 9, 2006, 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 DG Flugzeugbau GmbH Model DG-1000S sailplanes. This
proposal was published in the Federal Register as a notice of proposed
rulemaking (NPRM) on May 16, 2006 (71 FR 28287). The NPRM proposed to
require you to modify the elevator control at the stabilizer assembly,
replace a placard on the fin, and incorporate changes in the FAA-
approved SFM.

Comments

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

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.

Costs of Compliance

We estimate that this AD affects 8 sailplanes in the U.S. registry.
We estimate the following costs to do the modification and
replacement of the placard on the fin:

----------------------------------------------------------------------------------------------------------------
Total cost per
Labor cost Parts cost sailplane Total cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
2 work-hours x $80 per hour = $160..... $60 $220 8 x $220 = $1,760
----------------------------------------------------------------------------------------------------------------

We estimate the following costs to do the incorporation of changes
in the FAA-approved SFM:

----------------------------------------------------------------------------------------------------------------
Total cost per
Labor cost Parts cost sailplane Total cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
1 work-hour x $80 per hour = $80... Not applicable........ $80 8 x $80 = $640
----------------------------------------------------------------------------------------------------------------

Authority for This Rulemaking

Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, Section 106 describes the
authority of the FAA Administrator. Subtitle VII, Aviation Programs,
describes in more detail the scope of the agency's authority.
We are issuing this rulemaking under the authority described in
Subtitle VII, Part A, Subpart III, Section 44701, ``General
requirements.'' Under that section, Congress charges the FAA with
promoting safe flight of civil aircraft in air commerce by prescribing
regulations for practices, methods, and procedures the Administrator
finds necessary for safety in air commerce. This regulation is within
the scope of that authority because it addresses an unsafe condition
that is likely to exist or develop on products identified in this AD.

Regulatory Findings

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

[[Page 46394]]

the national government and the States, or on the distribution of power
and responsibilities among the various levels of government.
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
other information as included in the Regulatory Evaluation) 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 ``Docket
No. FAA-2006-24255; Directorate Identifier 2006-CE-25-AD'' in your
request.
