Airworthiness Directives; 328 Support Services GmbH Dornier Model 
328-100 and -300 Airplanes

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

ACTION: Final rule; request for comments.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for the 
products listed above. This AD results from mandatory continuing 
airworthiness information (MCAI) originated 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 a recent Aileron Dual Load Path and Linkage Inspection, 
which is a certification maintenance requirement (CMR) task, the 
installed control rods were found to be corroded. The affected rod 
assemblies

[[Page 21545]]

were removed for investigation and it was found that the Tab Side 
Fitting was cracked.
    Subsequently, similar cracks were found on another aeroplane in 
a supporting lever of the Control Rod attachment fitting of the Trim 
Tab. Those cracks were found during the applicable CMR inspection.
    This condition, if not corrected, could lead to structural 
failure of the dual load path attachment arrangement of the affected 
trim and spring tabs, possibly resulting in a flutter problem that 
could lead to loss of control of the aeroplane.
* * * * *

This AD requires actions that are intended to address the unsafe 
condition described in the MCAI.

DATES: This AD becomes effective May 26, 2009.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of May 26, 2009.

SUPPLEMENTARY INFORMATION:

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2009-0044, dated February 27, 2009 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    During a recent Aileron Dual Load Path and Linkage Inspection, 
which is a certification maintenance requirement (CMR) task, the 
installed control rods were found to be corroded. The affected rod 
assemblies were removed for investigation and it was found that the 
Tab Side Fitting was cracked.
    Subsequently, similar cracks were found on another aeroplane in 
a supporting lever of the Control Rod attachment fitting of the Trim 
Tab. Those cracks were found during the applicable CMR inspection.
    This condition, if not corrected, could lead to structural 
failure of the dual load path attachment arrangement of the affected 
trim and spring tabs, possibly resulting in a flutter problem that 
could lead to loss of control of the aeroplane.
    For the reasons described above, this [EASA] AD requires a one-
time inspection of all flight controls trim and spring tab 
assemblies and their surrounding area, the replacement of any parts 
that are found to be cracked and the reporting of all findings to 
the TC [type certificate] holder. This AD is considered to be an 
interim action and the current [CMR] inspection interval for the 
affected parts may be reduced.

You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    328 Support Services has issued Service Bulletins SB-328-27-483 and 
SB-328J-27-233, both including Compliance Report, both dated December 
30, 2008. The actions described in this service information are 
intended to correct the unsafe condition identified in the MCAI.

FAA's Determination and Requirements of This AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are issuing this AD because we 
evaluated all pertinent information and determined the unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Differences Between the 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.

FAA's Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because 
structural failure of the control rod attachment fittings could lead to 
control surface flutter, and consequent loss of control of the 
airplane. Therefore, we determined that notice and opportunity for 
public comment before issuing this AD are impracticable and that good 
cause exists for making this amendment effective in fewer than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not precede it by notice and opportunity for public 
comment. We invite you to send any written relevant data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include ``Docket No. FAA-2009-0419; Directorate 
Identifier 2009-NM-050-AD'' at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of this AD. We will consider all 
comments received by the closing date and may amend this AD because of 
those comments.
    We will post all comments we receive, without change, to <a href="http://www.regulations.gov">http://www.regulations.gov</a>, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

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,

[[Page 21546]]

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 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 regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket.
