Airworthiness Directives; AvCraft Dornier Model 328-300 Airplanes

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

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain AvCraft Dornier Model 328-300 airplanes. This AD requires 
modifying the electrical wiring of the fuel pumps; installing 
insulation at the flow control and shut-off valves, and other 
components of the environmental control system; installing markings at 
fuel wiring harnesses; replacing the wiring harness of the auxiliary 
fuel system with a new wiring harness; and installing insulated 
couplings in the fuel system; as applicable. This 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 is prompted by the results of fuel system reviews 
conducted by the airplane 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 becomes effective September 6, 2005.
    The incorporation by reference of certain publications listed in 
the AD is approved by the Director of the Federal Register as of 
September 6, 2005.

ADDRESSES: For service information identified in this AD, contact 
AvCraft Aerospace GmbH, P.O. Box 1103, D-82230 Wessling, Germany.
    Docket: The AD docket contains the proposed AD, comments, and any 
final disposition. You can examine the AD docket on the Internet at 
http://dms.dot.gov, or in person at the Docket Management Facility 
office between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The Docket Management Facility office (telephone (800) 647-
5227) is located on the plaza level of the Nassif Building at the U.S. 
Department of Transportation, 400 Seventh Street, SW., room PL-401, 
Washington, DC. This docket number is FAA-2005-21054; the directorate 
identifier for this docket is 2005-NM-054-AD.

FOR FURTHER INFORMATION CONTACT: Dan Rodina, Aerospace Engineer, 
International Branch, ANM-116, FAA, Transport Airplane Directorate, 
1601 Lind Avenue, SW., Renton, Washington 98055-4056; telephone (425) 
227-2125; fax (425) 227-1149.

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39 
with an AD for certain AvCraft Dornier Model 328-300 airplanes. That 
action, published in the Federal Register on April 26, 2005 (70 FR 
21346), proposed to require modifying the electrical wiring of the fuel 
pumps; installing insulation at the flow control and shut-off valves, 
and other components of the environmental control system; installing 
markings at fuel wiring harnesses; replacing the wiring harness of the 
auxiliary fuel system with a new wiring harness; and installing 
insulated couplings in the fuel system; as applicable. That action also 
proposed to require revising the Airworthiness Limitations section of 
the Instructions for Continued Airworthiness to incorporate new 
inspections of the fuel tank system.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We have considered the single comment that was 
submitted on the proposed AD.

Provide for Incorporation of Temporary Revision By Normal Revision 
Process

    The commenter requests that we revise paragraph (h) of the proposed 
AD to provide for incorporation of AvCraft Temporary Revision (TR) ALD-
028, dated October 15, 2003, into the body of the Airworthiness 
Limitations section of the Instructions for Continued Airworthiness 
document through the normal revision process. The commenter notes that 
the proposed AD, as written, would require the TR to remain in the 
Airworthiness Limitations section forever. However, once the 
information in the TR is incorporated into the Airworthiness 
Limitations section through the normal revision process, the TR 
document will be unnecessary.
    We agree. We have revised paragraph (h) of this AD accordingly, and 
added a new note, Note 1, to clarify the revised language in paragraph 
(h). These changes will allow the TR to be removed from the 
Airworthiness Limitations once the information in the TR has been 
incorporated into the Airworthiness Limitations by the normal revision 
process.

Explanation of Change to Applicability

    We have revised the applicability of this AD to identify model 
designations as published in the most recent type certificate data 
sheet for the affected model.

Explanation of Changes to Tables 1 and 2 of Proposed AD

    Tables 1 and 2 of the proposed AD incorrectly referred to 
paragraphs that do not exist in the referenced service bulletins. We 
have revised Tables 1 and 2 of this AD to refer to the correct 
paragraphs in the referenced service bulletins.

[[Page 44047]]

Conclusion

    We have carefully reviewed the available data, including the 
comment that has been submitted, and determined that air safety and the 
public interest require adopting the AD with the changes described 
previously. We have determined that these changes will neither increase 
the economic burden on any operator nor increase the scope of the AD.

Costs of Compliance

    The following table provides the estimated costs for U.S. operators 
to comply with this AD. The average labor rate is $65 per hour.

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 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. See the ADDRESSES section for a location to 
examine the regulatory evaluation.

Revision to Airworthiness Limitations

    (h) Within 12 months after the effective date of this AD, revise 
the Airworthiness Limitations section of the Instructions for 
Continued Airworthiness to incorporate the information in AvCraft 
Temporary Revision (TR) ALD-028, dated October 15, 2003, into the 
AvCraft 328JET Airworthiness Limitations Document. Thereafter, 
except as provided in paragraph (i) of this AD, no alternative 
inspection intervals may be approved for this fuel tank system.

    Note 1: This may be done by inserting a copy of AvCraft TR ALD-
028, dated October 15, 2003, in the AvCraft 328JET Airworthiness 
Limitations Document. When this TR has been included in general 
revisions of the AvCraft 328JET Airworthiness Limitations Document, 
the temporary revision no longer needs to be inserted into the 
revised Airworthiness Limitations document.

Alternative Methods of Compliance (AMOCs)

    (i) The Manager, International Branch, ANM-116, Transport 
Airplane Directorate, FAA, has the authority to approve AMOCs for 
this AD, if requested in accordance with the procedures found in 14 
CFR 39.19.
