Airworthiness Directives; GROB-WERKE GMBH & CO KG Models G102

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for the
products listed above. This AD results from mandatory continuing
airworthiness information (MCAI) issued by an aviation authority of
another country to identify and correct an unsafe condition on an
aviation product. The MCAI describes the unsafe condition as:

During an annual inspection, a water ballast hose connector was
found disconnected from the fuselage wall of an Astir CS.
The investigation has shown that the hose-fuselage connection
bonding has been degraded over years of service.
This condition, if not corrected, could lead to the following
consequences:

[[Page 47183]]

--The water contained in the wing tanks could run down into the
fuselage and fuselage tail which could cause a displacement of the
sailplane centre of gravity and consequently may lead to the loss of
the sailplane controllability, or/and
--The loosened hose may jam the flight controls (push rods) and
consequently may lead to the loss of the sailplane controllability.

We are issuing this AD to require actions to correct the unsafe
condition on these products.

DATES: This AD becomes effective September 9, 2010.
On September 9, 2010, the Director of the Federal Register approved
the incorporation by reference of certain publications listed in this
AD.

SUPPLEMENTARY INFORMATION:

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would apply to the specified products.
That NPRM was published in the Federal Register on May 3, 2010 (75 FR
23194). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:

For the reason stated above, the original issue of this AD
required the inspection of the waterballast system hose-fuselage
connections and the accomplishment of the relevant corrective
actions (repair) as necessary.
This AD is revised to clarify the purpose of the insertion of
the repetitive inspection in the Aircraft Maintenance Programme and
to refer to a more appropriate scheduled maintenance review for the
insertion of the repetitive inspection in the Aircraft Maintenance
Programme.

Comments

We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM or on the determination of
the cost to the public.

Conclusion

We reviewed the available data and determined that air safety and
the public interest require adopting the AD as proposed.

Differences Between This AD and the MCAI or Service Information

We have reviewed the MCAI and related service information and, in
general, agree with their substance. But we might have found it
necessary to use different words from those in the MCAI to ensure the
AD is clear for U.S. operators and is enforceable. In making these
changes, we do not intend to differ substantively from the information
provided in the MCAI and related service information.
We might also have required different actions in this AD from those
in the MCAI in order to follow FAA policies. Any such differences are
highlighted in a Note within the AD.

Costs of Compliance

We estimate that this AD will affect 113 products of U.S. registry.
We also estimate that it will take about 1 work-hour per product to
comply with the basic requirements of this AD. The average labor rate
is $85 per work-hour.
Based on these figures, we estimate the cost of this AD to the U.S.
operators to be $9,605 or $85 per product.
In addition, we estimate that any necessary follow-on actions would
take about 1 work-hour and require parts costing $5, for a cost of $90
per product. We have no way of determining the number of products that
may need these actions.

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
rulemaking action.

Regulatory Findings

We 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.
For the reasons discussed above, I certify this AD:
(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.
We prepared a regulatory evaluation of the estimated costs to
comply with this AD and placed it in the AD Docket.

Examining the AD Docket

You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Management Facility
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The AD docket contains the NPRM, the regulatory evaluation,
any comments received, and other information. The street address for
the Docket Office (telephone (800) 647-5527) is in the ADDRESSES
section. Comments will be available in the AD docket shortly after
receipt.

connection following paragraph 1.8 of Grob Aircraft Service Bulletin
No. MSB-GROB-003, dated October 21, 2009.
(2) If, during any inspection required by paragraph (f)(1) of
