Start Preamble

AGENCY:

Federal Aviation Administration, DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Hamburger Flugzeugbau G.m.b.H. Model HFB 320 HANSA airplanes. This proposal would require replacement of the elevator trim control cable assemblies with new assemblies. This action is necessary to prevent loss of elevator trim and possible loss of rudder and/or elevator function due to stress-corrosion cracking of certain cable terminals. This action is intended to address the identified unsafe condition.

DATES:

Comments must be received by December 15, 2003.

ADDRESSES:

Submit comments in triplicate to the Federal Aviation Administration (FAA), Transport Airplane Directorate, ANM-114, Attention: Rules Docket No. 2002-NM-185-AD, 1601 Lind Avenue, SW., Renton, Washington 98055-4056.

Availability of NPRMs

Any person may obtain a copy of this NPRM by submitting a request to the FAA, Transport Airplane Directorate, ANM-114, Attention: Rules Docket No. 2002-NM-185-AD, 1601 Lind Avenue, SW., Renton, Washington 98055-4056.

Discussion

The Luftfahrt-Bundesamt (LBA), which is the airworthiness authority for Germany, notified the FAA that an unsafe condition may exist on certain Hamburger Flugzeugbau G.m.b.H. Model HFB 320 HANSA airplanes. The LBA advises that there is the possibility of stress-corrosion cracking on MS 21260 flight control cable terminals. This condition, if not corrected, could result in loss of elevator trim and possible loss of rudder and/or elevator function.

Explanation of Relevant Service Information

The manufacturer has issued HFB 320 Hansa Service Bulletin 27-75, dated May 31, 2002, which describes procedures for replacement of the elevator trim control cable assemblies with new assemblies. Accomplishment of the actions specified in the service bulletin is intended to adequately address the identified unsafe condition. The LBA classified this service bulletin as mandatory and issued LBA airworthiness directive 2002-157, dated July 11, 2002, in order to assure the continued airworthiness of these airplanes in Germany.

FAA's Conclusions

This airplane model is manufactured in Germany and is type certificated for operation in the United States under the provisions of section 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. The FAA has examined the findings of the LBA, reviewed all available information, and determined that AD action is necessary for products of this type design that are certificated for operation in the United States.

Explanation of Requirements of Proposed Rule

Since an unsafe condition has been identified that is likely to exist or develop on other airplanes of the same type design registered in the United States, the proposed AD would require accomplishment of the actions specified in the service bulletin described previously.Start Printed Page 64283

Cost Impact

The FAA estimates that 6 airplanes of U.S. registry would be affected by this proposed AD, that it would take approximately 20 work hours to accomplish the proposed replacement, and that the average labor rate is $65 per work hour. Required parts would cost approximately $500 per airplane. Based on these figures, the cost impact of the proposed AD on U.S. operators is estimated to be $10,800, or $1,800 per airplane.

The cost impact figure discussed above is based on assumptions that no operator has accomplished any of the proposed requirements of this AD action, and that no operators would accomplish those actions in the future if this proposed AD were not adopted. The cost impact figures discussed in AD rulemaking actions represent only the time necessary to perform the specific actions actually required by the AD. These figures typically do not include incidental costs, such as the time required to gain access and close up, planning time, or time necessitated by other administrative actions.

Regulatory Impact

The regulations proposed herein 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. Therefore, it is determined that this proposal would not have federalism implications under Executive Order 13132.

For the reasons discussed above, I certify that this 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) if promulgated, 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. A copy of the draft regulatory evaluation prepared for this action is contained in the Rules Docket. A copy of it may be obtained by contacting the Rules Docket at the location provided under the caption ADDRESSES.
