Start Preamble

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 328-100 and -300 airplanes. This AD requires a pressure test and detailed inspection of each fuselage drain line to determine if there is a blockage, and related investigative/corrective actions if necessary. This AD is prompted by a report of leakage at one of the drain lines in the fuselage. We are issuing this AD to prevent blockage within the drain lines, causing fluids to collect. These fluids may freeze and expand, damaging the drain lines, and allowing fuel to leak into the cabin and fuel vapors to come into contact with ignition sources, which could result in consequent fire in the cabin.

DATES:

This AD becomes effective July 26, 2005.

The incorporation by reference of certain publications listed in the AD is approved by the Director of the Federal Register as of July 26, 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-2005-20866; the directorate identifier for this docket is 2004-NM-258-AD.

SUPPLEMENTARY INFORMATION:

The FAA proposed to amend 14 CFR part 39 with an AD for certain Avcraft Dornier Model 328-100 and -300 series airplanes. That action, published in the Federal Register on April 6, 2005 (70 FR 17357), proposed to require a pressure test and detailed inspection of each fuselage drain line to determine if there is a blockage, and related investigative/corrective actions if necessary.

Comments

We provided the public the opportunity to participate in the development of this AD. No comments have been submitted on the proposed AD or on the determination of the cost to the public.

Explanation of Change to Applicability

We have revised the applicability of the proposed AD to identify model designations as published in the most recent type certificate data sheet for the affected models. In addition, we noticed that we had inadvertently reversed the qualifiers of the airplane models specified in the applicability of the proposed AD. The applicability for this AD has been corrected for this AD and now reads, “This AD applies to Avcraft Dornier Model 328-100 series airplanes having serial numbers 3005 through 3119 inclusive, and Avcraft Dornier Model 328-300 series airplanes without option 033F003 “Extended Range” installed; certificated in any category.”Start Printed Page 35517

Conclusion

We have carefully reviewed the available data 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

We estimate that this AD affects about 53 Model 328-100 airplanes and 57 Model 328-300 airplanes of U.S. registry. The following table provides the estimated costs for U.S. operators to comply with 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 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.

Do any applicable related investigative or corrective action before further flight.

Detailed Inspection

(g) After doing the pressure test required by paragraph (f) of this AD, but not later than 24 months after the effective date of this AD: Perform a detailed inspection and related investigative and corrective actions, in accordance with Part 2 of the Accomplishment Instructions of Avcraft Service Bulletin SB-328-53-462, Revision 1, dated July 15, 2004; or SB-328J-53-214, Revision 1, dated July 15, 2004; as applicable.

Note 1:

For the purposes of this AD, a detailed inspection is: “An intensive examination of a specific item, installation, or assembly to detect damage, failure, or irregularity. Available lighting is normally supplemented with a direct source of good lighting at an intensity deemed appropriate. Inspection aids such as mirror, magnifying lenses, etc., may be necessary. Surface cleaning and elaborate procedures may be required.”
