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.

ADDRESSES: You may examine the AD docket on the Internet at http://www.regulations.gov or in person at Document Management Facility, U.S.

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:

    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.

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.

2. The FAA amends Sec.  39.13 by adding the following new AD:

2007-23-06 CTRM Aviation Sdn. Bhd. (Formerly Eagle Aircraft 
(Malaysia) Sdn. Bhd.): Amendment 39-15252; Docket No. FAA-2007-
28957; Directorate Identifier 2007-CE-069-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective December 
11, 2007.

Affected ADs

    (b) None.

Applicability

    (c) This AD affects Model Eagle 150B airplanes, all serial 
numbers, that are certificated in any category.

Subject

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

Reason

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

    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.

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.
