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:

An operator has reported severe exfoliation corrosion on Wing/
Canard Flap Hinges, P/N 5731D01-16 (middle and outboard hinges) on
his Eagle 150B. The corrosion has been detected during 100-hour
inspection. The aircraft has accumulated more than 1000 flight
hours. The corrosion is so severe that one of the Flap Hinges
thickness has been reduced by 50%. The corrosion is not easily
detected because the Flap Hinge is sandwiched between the Flap Hinge
Support Bracket P/N 5731D01-01.

The failure of the hinge bracket may result in disintegration of
flap/canard wing thus leading to loss of control, with catastrophic
consequences.

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

DATES: This AD becomes effective December 11, 2007.
On December 11, 2007, 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 September 14, 2007
(72 FR 52519). That NPRM proposed to correct an unsafe condition for
the specified products. The MCAI states:

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

Based on the service information, we estimate that this AD will
affect about 6 products of U.S. registry. We also estimate that it will
take about 3 work-hours per product to comply with the basic
requirements of this AD. The average labor rate is $80 per work-hour.
Based on these figures, we estimate the cost of the AD to U.S.
operators to be $1,440, or $240 per product.
In addition, we estimate that any necessary follow-on actions will
take about 4 work-hours and require parts costing $226, for a cost of
$546 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.

Applicability

Subject

(d) Air Transport Association of America (ATA) Code 57: Wings.

Reason

(e) The mandatory continuing airworthiness information (MCAI)
states:

The failure of the hinge bracket may result in disintegration of
flap/canard wing thus leading to loss of control, with catastrophic
consequences.

The MCAI requires you to visually inspect the flap hinges and flap
hinge support brackets for any corrosion. You are to take corrective
action if you find any corrosion.

Actions and Compliance

(f) Unless already done, do the following actions:
(1) Within the next 25 hours time-in-service (TIS) after
December 11, 2007 (the effective date of this AD), inspect the flap
hinges and flap hinge support brackets for any corrosion, following
CTRM Aviation Mandatory Service Bulletin SB 1126, dated July 19,
2007.
(2) Before further flight, if you find any corrosion as a result
of any inspection required by paragraph (f)(1) of this AD, take
corrective action following CTRM Aviation Mandatory Service Bulletin
SB 1126, dated July 19, 2007.

FAA AD Differences

Note: This AD differs from the MCAI and/or service information
as follows: No Differences.

Other FAA AD Provisions
