Airworthiness Directives; 328 Support Services GmbH (Type 
Certificate Previously Held by AvCraft Aerospace GmbH; Fairchild 
Dornier GmbH; Dornier Luftfahrt GmbH) Model 328-100 and 328-300 
Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the 
products listed above. This proposed 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:

    Based on in-service experience, the System Safety Analyses for 
the Flight Controls have been reviewed and their conclusions have 
been accepted during the latest Candidate Maintenance Coordination 
Committee meeting.
    This review resulted in reduced inspection intervals, 
specifically for the flight controls tab-to-actuator linkage 
[certification maintenance requirements] CMR** repetitive 
inspections, which have been identified as mandatory actions for 
continued airworthiness.
    Failure of these components or their constituent parts could 
lead to reduced control of the aeroplane.
* * * * *
The proposed AD would require actions that are intended to address the 
unsafe condition described in the MCAI.

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 2010-0054, dated March 25, 2010 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    Based on in-service experience, the System Safety Analyses for 
the Flight Controls have been reviewed and their conclusions have 
been accepted during the latest Candidate Maintenance Coordination 
Committee meeting.
    This review resulted in reduced inspection intervals, 
specifically for the flight controls tab-to-actuator linkage CMR** 
repetitive inspections, which have been identified as mandatory 
actions for continued airworthiness.
    Failure of these components or their constituent parts could 
lead to reduced control of the aeroplane.
    Consistent with the EASA policy to require compliance with any 
new and reduced airworthiness limitations by taking AD action and 
for the reasons described above, this EASA AD requires the 
accomplishment of the reduced-interval repetitive inspections and, 
depending on findings, related corrective action(s). In addition, 
this AD requires the implementation of the affected reduced 
inspection intervals and associated corrective actions into the 
operator's approved maintenance programme.

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

Relevant Service Information

    328 Support Services GmbH has issued Dornier 328 Certification 
Maintenance Requirements Document TM-CMR-010793-ALL, Revision 13, dated 
April 30, 2007; and Dornier 328JET Certification Maintenance 
Requirements Document TM-CMR-010599-ALL, Revision 2, dated May 1, 2007. 
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 Proposed 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 proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

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 proposed 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 proposed AD.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 63 products of U.S. registry. We also estimate that 
it would take about 1 work-hour per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $85 per 
work-hour. Based on these figures, we estimate the cost of the proposed 
AD on U.S. operators to be $5,355, or $85 per product.

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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 proposed 
regulation:
    (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),
    (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 proposed AD and placed it in the AD docket.

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

    (h) The initial compliance time for the CMR tasks identified in 
table 1 of this AD is within 500 flight hours after the most recent 
inspection, or within 100 flight hours after the effective date of 
this AD, whichever occurs later.

No Alternative Inspections or Inspection Intervals

    (i) After accomplishing the revision required by paragraph (g) 
of this AD, no alternative inspection or inspection interval may be 
used unless the inspection or inspection interval is approved as an 
alternative methods of compliance (AMOC) in accordance with the 
procedures specified in paragraph (j) of this AD.

FAA AD Differences

    Note 1: This AD differs from the MCAI and/or service information 
as follows:
    Although EASA Airworthiness Directive 2010-0054, dated March 25, 
2010, specifies both revising the maintenance program, doing certain 
repetitive actions, and doing corrective actions, this AD only 
requires the revision. Requiring a revision of the maintenance 
program, rather than requiring individual repetitive actions, 
requires operators to record AD compliance only at the time the 
revision is made.

Other FAA AD Provisions

    (j) The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance: The Manager, 
International Branch, ANM-116, Transport Airplane Directorate, FAA, 
has the authority to approve AMOCs for this AD, if requested using 
the procedures found in 14 CFR 39.19. In accordance with 14 CFR 
39.19, send your request to your principal inspector or local Flight 
Standards District Office, as appropriate. If sending information 
directly to the International Branch, send it to Attn: Tom 
Rodriguez, Aerospace Engineer, International Branch, ANM-116, 
Transport Airplane Directorate, FAA 1601 Lind Avenue, SW., Renton, 
Washington 98057-3356; telephone (425) 227-1137; fax (425) 227-1149. 
Information may be e-mailed to: 9-ANM-116-AMOC-REQUESTS@faa.gov. 
Before using any approved AMOC, notify your appropriate principal 
inspector, or lacking a principal inspector, the manager of the 
local flight standards district office/certificate holding district 
office. The AMOC approval letter must specifically reference this 
AD.
    (2) Airworthy Product: For any requirement in this AD to obtain 
corrective actions from a manufacturer or other source, use these 
actions if they are FAA-approved. Corrective actions are considered 
FAA-approved if they are approved by the State of Design Authority 
(or their delegated agent). You are required to assure the product 
is airworthy before it is returned to service.
