Accomplishing the actions specified in the service information is intended to adequately address the unsafe condition. The LBA mandated the service information and issued German airworthiness directive D–2004–005, dated January 8, 2004, to ensure the continued airworthiness of these airplanes in Germany. Discussion The Luftfahrt-Bundesamt (LBA), which is the airworthiness authority for Germany, notified us that an unsafe condition may exist on certain Dornier Model 328–300 series airplanes. The LBA advises that there have been reports that, during maintenance, water (from rain or condensation) was found in the elevator assembly. The water accumulates in the elevator due to the lack of a drain hole and could freeze in a cold environment (e.g., due to high altitude or winter weather). Accumulated water or ice in the elevator assembly, if not corrected, could result in possible corrosion that reduces the structural integrity of the flight control surface, or in an unbalanced flight control surface. These conditions could result in reduced controllability of the airplane. FAA’s Determination and Requirements of the Proposed AD Relevant Service Information AvCraft Aerospace GmbH has issued Dornier Service Bulletin SB–328J–55– 203, Revision 1, dated November 19, 2003. The service bulletin describes This airplane model is manufactured in Germany and is type certificated for operation in the United States under the provisions of § 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness agreement. Pursuant to this bilateral airworthiness agreement, the LBA has kept the FAA informed of the situation described above. We have examined the LBA’s findings, evaluated all pertinent information, and determined that we need to issue an AD for products of this type design that are certificated for operation in the United States. Therefore, we are proposing this AD, which would require accomplishing the actions specified in the service information described previously. Costs of Compliance The following table provides the estimated costs for U.S. operators to comply with this proposed AD. ESTIMATED COSTS Action Work hours Average labor rate per hour Parts Cost per airplane Number of U.S.-registered airplanes Fleet cost Installing drain hole .................................. 1 $65 $100 $165 49 $8,085 Authority of 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 VerDate jul<14>2003 14:39 Feb 14, 2005 Jkt 205001 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 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 that the proposed regulation: PO 00000 Frm 00018 Fmt 4702 Sfmt 4702 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 proposed AD. See the ADDRESSES section for a location to examine the regulatory evaluation.

Discussion

    The Luftfahrt-Bundesamt (LBA), which is the airworthiness authority 
for Germany, notified us that an unsafe condition may exist on certain 
Dornier Model 328-300 series airplanes. The LBA advises that there have 
been reports that, during maintenance, water (from rain or 
condensation) was found in the elevator assembly. The water accumulates 
in the elevator due to the lack of a drain hole and could freeze in a 
cold environment (e.g., due to high altitude or winter weather). 
Accumulated water or ice in the elevator assembly, if not corrected, 
could result in possible corrosion that reduces the structural 
integrity of the flight control surface, or in an unbalanced flight 
control surface. These conditions could result in reduced 
controllability of the airplane.

Relevant Service Information

    AvCraft Aerospace GmbH has issued Dornier Service Bulletin SB-328J-
55-203, Revision 1, dated November 19, 2003. The service bulletin 
describes procedures for installing a drain hole in the lower skin of 
the left- and right-hand elevator horns. Accomplishing the actions 
specified in the service information is intended to adequately address 
the unsafe condition. The LBA mandated the service information and 
issued German airworthiness directive D-2004-005, dated January 8, 
2004, to ensure the continued airworthiness of these airplanes in 
Germany.

FAA's Determination and Requirements of the Proposed AD

    This airplane model is manufactured in Germany and is type 
certificated for operation in the United States under the provisions of 
Sec.  21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the 
applicable bilateral airworthiness agreement. Pursuant to this 
bilateral airworthiness agreement, the LBA has kept the FAA informed of 
the situation described above. We have examined the LBA's findings, 
evaluated all pertinent information, and determined that we need to 
issue an AD for products of this type design that are certificated for 
operation in the United States. Therefore, we are proposing this AD, 
which would require accomplishing the actions specified in the service 
information described previously.

Costs of Compliance

    The following table provides the estimated costs for U.S. operators 
to comply with this proposed AD.

Authority of 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 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 that the 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); 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 proposed AD. See the ADDRESSES section for a location 
to examine the regulatory evaluation.
