Airworthiness Directives; 328 Support Services GmbH (Dornier) 
Model 328-100 Airplanes

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

ACTION: Final rule; request for comments.

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

SUMMARY: The FAA is revising an existing airworthiness directive (AD), 
which applies to all 328 Support Services GmbH (Dornier) Model 328-100 
airplanes. That AD currently requires modifying the electrical wiring 
of the fuel pumps; installing insulation at the hand flow control and 
shut-off valves, and other components of the environmental control 
system; and installing markings at fuel wiring harnesses. That AD also 
requires revising the Airworthiness Limitations section of the 
Instructions for Continued Airworthiness to incorporate new inspections 
of the fuel tank system. This AD clarifies the intended effect of the 
AD on spare and on-airplane fuel tank system components. This AD 
results from fuel system reviews conducted by the manufacturer. We are 
issuing this AD to reduce the potential of ignition sources inside fuel 
tanks, which, in combination with flammable fuel vapors, could result 
in fuel tank explosions and consequent loss of the airplane.

DATES: This AD is effective December 21, 2009.
    On September 17, 2008 (73 FR 47027, August 13, 2008), the Director 
of the Federal Register approved the incorporation by reference of 
certain publications listed in the AD.
    On July 29, 2005 (70 FR 36470, June 24, 2005), the Director of the 
Federal Register approved the incorporation by reference of certain 
other publications listed in the AD.
    We must receive any comments on this AD by January 19, 2010.

SUPPLEMENTARY INFORMATION:

Discussion

    On July 29, 2008, we issued AD 2008-17-01, Amendment 39-15639 (73 
FR 47027, August 13, 2008). That AD applied to all 328 Support Services 
GmbH (Dornier) Model 328-100 airplanes. That AD required modifying the 
electrical wiring of the hand fuel pumps; installing insulation at the 
hand flow control and shut-off valves, and other components of the 
environmental control system; and installing markings at fuel wiring 
harnesses. That AD also required revising the Airworthiness Limitations 
section (ALS) of the Instructions for Continued Airworthiness to 
incorporate new inspections of the fuel tank system.
    Critical design configuration control limitations (CDCCLs) are 
limitation requirements to preserve a critical ignition source 
prevention feature of the fuel tank system design that is necessary to 
prevent the occurrence of an unsafe condition. The purpose of a CDCCL 
is to provide instruction to retain the critical ignition source 
prevention feature during configuration change that may be caused by 
alterations, repairs, or maintenance actions. A CDCCL is not a periodic 
inspection.

Actions Since AD Was Issued

    Since we issued that AD, we have determined that it is necessary to 
clarify the AD's intended effect on spare and on-airplane fuel tank 
system components, regarding the use of maintenance manuals and 
instructions for continued airworthiness.
    Section 91.403(c) of the Federal Aviation Regulations (14 CFR 
91.403(c)) specifies the following:

    No person may operate an aircraft for which a manufacturer's 
maintenance manual or instructions for continued airworthiness has 
been issued that contains an airworthiness limitation section unless 
the mandatory * * * procedures * * * have been complied with.

    Some operators have questioned whether existing components affected 
by the new CDCCLs must be reworked. We did not intend for the AD to 
retroactively require rework of components that had been maintained 
using acceptable methods before the effective date of the AD. Owners 
and operators of the affected airplanes therefore are not required to 
rework affected components identified as airworthy or installed on the 
affected airplanes before the required revisions of the ALS. But once 
the CDCCLs are incorporated into the ALS, future maintenance actions on 
components must be done in accordance with those CDCCLs.

FAA's Determination and Requirements of This AD

    The affected products have been approved by the aviation authority 
of another country, and are approved for operation in the United 
States. 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. This new AD 
retains the requirements of the existing AD, and adds a new note to 
clarify the intended effect of the AD on spare and on-airplane fuel 
tank system components.

Costs of Compliance

    This revision imposes no additional economic burden. The current 
costs for this AD are repeated for the convenience of affected 
operators, as follows:
    This AD affects about 16 airplanes of U.S. registry. The actions 
that are required by AD 2005-13-24 and

[[Page 63570]]

retained in this AD take about 70 work hours per airplane, at an 
average labor rate of $80 per work hour. Required parts cost about 
$14,118 per airplane. Based on these figures, the estimated cost of the 
currently required actions is $315,488, or $19,718 per airplane.
    The ALS revision required by AD 2008-17-01 and retained in this AD 
takes about 1 work hour per airplane. Based on these figures, the 
estimated cost of this action specified in this AD for U.S. operators 
is $1,280, or $80 per airplane.

FAA's Justification and Determination of the Effective Date

    This revision merely clarifies the intended effect on spare and on-
airplane fuel tank system components, and makes no substantive change 
to the AD's requirements. For this reason, it is found that notice and 
opportunity for prior public comment for this action are unnecessary, 
and good cause exists for making this amendment effective in less than 
30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not provide you with notice and an opportunity to 
provide your comments before it becomes effective. However, we invite 
you to send any written data, views, or arguments about this AD. Send 
your comments to an address listed under the ADDRESSES section. Include 
``Docket No. FAA-2009-1074; Directorate Identifier 2009-NM-177-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 http://
www.regulations.gov, 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, 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 have 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 that the 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); 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. See the ADDRESSES 
section for a location to examine the regulatory evaluation.
