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

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

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) 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 maintenance, it has been discovered that at the 
installation of the fixation brackets for rudder spring tabs and 
trim tabs an incorrect installation of the fixation brackets may 
have occurred. * * *
    If the orientation of the fixation bracket is reversed or upside 
down the screws may not reach into the helicoil thread to a 
sufficient depth.
    An incorrect installation, if not detected and corrected, could 
lead to an in-flight failure of the fixation brackets for rudder 
spring tabs and trim tabs resulting in and reduced control of the 
aeroplane.
* * * * *

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

DATES: This AD becomes effective August 22, 2011.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of August 22, 
2011.

ADDRESSES: You may examine the AD docket on the Internet at http://www.regulations.gov or in person at the U.S. Department of 
Transportation, Docket Operations, M-30, West Building Ground Floor, 
Room W12-140, 1200 New Jersey Avenue, SE., Washington, DC.

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 April 8, 2011 (76 FR 
19721). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    During maintenance, it has been discovered that at the 
installation of the fixation brackets for rudder spring tabs and 
trim tabs an incorrect installation of the fixation brackets may 
have occurred. It is possible that the fixation bracket assembly may 
be incorrectly orientated and as a result the position of the 
helicoil inserts on the fixation bracket may be incorrect.
    If the orientation of the fixation bracket is reversed or upside 
down the screws may not reach into the helicoil thread to a 
sufficient depth.
    An incorrect installation, if not detected and corrected, could 
lead to an in-flight failure of the fixation brackets for rudder 
spring tabs and trim tabs resulting in and reduced control of the 
aeroplane.
    To address this potential unsafe condition, the TC [type 
certificate] holder has developed a one-time inspection to detect 
and correct any incorrect installations of the fixation brackets for 
rudder spring tabs and trim tabs.
    For the reasons described above, this [EASA] AD requires a one-
time [detailed] inspection of all rudder trim- and spring tab 
fixation brackets, the correction of any parts that are incorrectly 
installed and the reporting of all findings to the TC holder. This 
[EASA] AD is considered to be an interim action and an improved 
design bracket attachment is expected to be developed.

The detailed inspection includes determining if the helicoil inserts of 
the rudder trim tab and spring tab fixation brackets are correctly 
oriented and are facing the fitting surface, and if not, inspecting the 
fittings and helicoil inserts for correct installation. The corrective 
actions include re-orienting the fittings and helicoil inserts, and 
replacing the fitting with a serviceable one. You may obtain further 
information by examining the MCAI in the AD docket.

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 our FAA policies. Any such differences 
are highlighted in a Note within the AD.

Costs of Compliance

    We estimate that this AD will affect about 55 products of U.S. 
registry. We also estimate that it will take about 2 work-hours per 
product to comply with the basic requirements of this AD. The average 
labor rate is $85 per work-hour. Based on these figures, we estimate 
the cost of this AD to the U.S. operators to be $9,350, or $170 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 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.

Examining the AD Docket

    You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Operations office 
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 Operations office (telephone (800) 647-5527) is in the 
ADDRESSES section. Comments will be available in the AD docket shortly 
after receipt.
