Federal Aviation Administration, DOT.
Final rule; request for comments.
This amendment adopts a new airworthiness directive (AD) that applies to Aviointeriors S.p.A. (formerly ALVEN), Seat Model 312. This AD requires initial and repetitive inspections of the seat center crossmember for cracks, and if necessary, replacing the crossmember with a new crossmember. This amendment is prompted by reports of cracks in the crossmember that were found during normal maintenance. The FAA is issuing this AD to prevent the loss of the structural integrity of the seat due to cracks in the seat center crossmember.
Effective October 12, 2000. The incorporation by reference of certain publications listed in the rule is approved by the Director of the Federal Register as of October 12, 2000.
The FAA must receive any comments on this rule by November 27, 2000.

The Ente Nazionale per l'Aviaazione Civile (ENAC), which is the airworthiness authority for Italy, recently notified the FAA that an unsafe condition may exist on the crossmembers of Aviointeriors S.p.A. (formerly ALVEN) model 312 seats. The ENAC has advised the FAA that cracks were found in three seat center crossmembers during routine maintenance.
Manufacturer's Service Information
Aviointeriors has issued alert service bulletin (ASB) No. 312/912-01, Revision 1, dated October 7, 1999, that specifies procedures for inspecting the center crossmember, part number (P/N) DM03437-1, of the seat for cracks and, if necessary, replacing the crossmember with a serviceable part. The ENAC classified this service bulletin as mandatory and issued AD 99-421 in order to assure the airworthiness of these seats in Italy.
Bilateral Airworthiness Agreement
This seat is manufactured in Italy, and is approved for use on airplanes that are type certificated for operation in the United States under the provisions of § 21.617 of the Federal Aviation Regulations (14 CFR 21.617) and the applicable bilateral airworthiness agreement. Under this bilateral airworthiness agreement, the ENAC has kept the FAA informed of the situation described above. The FAA has examined the findings of the ENAC, reviewed all available information, and determined that AD action is necessary for seats of this design that are used on airplanes that are certificated for operation in the United States.
Requirements of this AD
The FAA has identified an unsafe condition that is likely to exist or develop on other seats of this same design. This AD is being issued to prevent the loss of the structural integrity of the seat due to cracks in the seat center crossmember. This AD requires an initial inspection within 20 days or 80 hours time-in-service (TIS), whichever occurs first, after the effective date of this AD, repetitive inspections within 650 hours TIS after the last inspection, and if necessary, the replacement of the seat center crossmember with a new crossmember. These actions must to be done in accordance with the service bulletin described previously.
Since a situation exists that requires the immediate adoption of this regulation, it is found that notice and opportunity for prior public comment are impracticable, and that good cause exists for making this amendment effective in less than 30 days.
Although this AD is in the form of a final rule that involves requirements affecting flight safety and was not preceded by notice and an opportunity for public comment, the FAA invites you to submit any written relevant data, views, or arguments. Submit your comments as specified under the “ADDRESSES” caption. Be sure to include the Rules Docket number 2000-NE-09-AD in the communication. We specifically invite comments on the overall regulatory economic, environmental, and energy aspects of the rule that might suggest a need to modify it. We will file a report in the AD Docket that summarizes each FAA contact with the public that is related to the substantive part of this rule. The FAA is examining the writing style we currently use in regulatory documents, in response to the presidential memorandum of June 1, 1998. That memorandum requires federal agencies to communicate more clearly with the public. You can get more information about the presidential memorandum and the plain language initiative at http://www.plainlanguage.gov. We also specifically invite comments on the chart-type format used to publish the actions required by this AD. This format was developed in consultation with the Office of the Federal Register, and the FAA is considering using this format, when appropriate, for future AD's. We will consider all comments received by the closing date, and may amend the rule.
If you want the FAA to acknowledge receipt of your comments, send a self-addressed, stamped postcard on which the following statement is made: “Comments to Docket Number 2000-NE-09-AD.” We will date stamp the postcard and return it to you. Start Printed Page 58179
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. Therefore, the FAA has determined that this AD does not have federalism implications under Executive Order 13132. Accordingly, the FAA has not consulted with state authorities before publication of this rule.
The FAA has determined that this regulation is an emergency regulation that must be issued immediately to correct an unsafe condition in aircraft, and is not a “significant regulatory action” under Executive Order 12866. Further, the FAA has determined that this AD involves an emergency regulation under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979). If a determination is made that this AD otherwise would be significant under DOT Regulatory Policies and Procedures, the FAA will prepare a final regulatory evaluation and place it in the AD Docket. You can get a copy of this evaluation, if one has been prepared, by sending a request to the FAA at the mailing address listed under the caption “ADDRESSES.” Your request must reference “AD Docket Number 2000-NE-09-AD.”Start List of Subjects
