ACTION: Final rule.
AGENCY:
SUMMARY: We are adopting a new
airworthiness directive (AD) for all
Twin Commander Aircraft Corporation
(Twin Commander) Models 690, 690A,
and 690B airplanes. This AD requires
you to inspect, visually and using
fluorescent dye penetrant, the support
structures for the inboard and center
aileron hinge fittings on both wings for
cracks and replace any cracked support
structure. This AD requires you to
reinforce the support structures for the
inboard and center aileron hinge fittings
on both wings. This AD results from
reports that cracks were found in the
support structures for the inboard and
center aileron hinge fittings on both
wings. We are issuing this AD to detect
and correct cracks in the support
structures for the inboard and center
aileron hinge fittings on both wings,
which could result in aileron failure.
This failure could lead to reduced
controllability or loss of control of the
airplane.
DATES: This AD becomes effective on
August 21, 2006.
As of August 21, 2006, the Director of
the Federal Register approved the
incorporation by reference of certain
publications listed in the regulation.

SUPPLEMENTARY INFORMATION:
Discussion
On March 10, 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
Twin Commander Models 690, 690A,
and 690B, airplanes. This proposal was
published in the Federal Register as a
notice of proposed rulemaking (NPRM)
on March 16, 2006 (71 FR 13558). The
NPRM proposed to require you to
inspect, visually and using fluorescent
dye penetrant, the support structures for
the inboard and center aileron hinge
fittings on both wings for cracks and
replace any cracked support structure.
The NPRM proposed to require you to
reinforce the support structures for the
inboard and center aileron hinge fittings
on both wings.
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 275
airplanes in the U.S. registry.
We estimate the following costs to do
the inspection of the support structures
of the inboard aileron hinge fittings on
both wings:

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 requirement.’’ 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
the national government and the States,
or on the distribution of power and
responsibilities among the various

SUMMARY: The FAA is adopting a new
airworthiness directive (AD) for certain
Airbus Model A330–200 and –300, and
A340–200 and –300 series airplanes.
This AD requires modifying certain
rotary actuator assemblies for the
leading edge slat. This AD results from
a leak found at the seal of the torque
limiter output shaft of the Type A rotary
actuator of leading edge slat No. 1. We
are issuing this AD to prevent a decrease
in the torque limiter function, which
could result in degradation and damage
to the attachment bolts of the leading
edge slat, loss of the slat, and
consequent reduced control of the
airplane.
This AD becomes effective
August 21, 2006.
The Director of the Federal Register
approved the incorporation by reference
of certain publications listed in the AD
as of August 21, 2006.

part 39 to include an AD that would
apply to certain Airbus Model A330–
200 and –300, and A340–200 and –300
series airplanes. That NPRM was
published in the Federal Register on
April 21, 2006 (71 FR 20599). That
NPRM proposed to require modifying
certain rotary actuator assemblies for the
leading edge slat.

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

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
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
