Federal Aviation Administration (FAA), Department of Transportation (DOT).
We are adopting a new airworthiness directive (AD) for certain Raytheon Aircraft Company (RAC) Model B300 airplanes. This AD requires you to modify the cabin passenger seats by installing a modification kit on each passenger seat, removing the existing technical standard order (TSO) label, and re-identifying each modified passenger seat assembly with a new part number. This AD results from the seats not meeting the ultimate load requirements of 14 CFR part 23 during structural testing of the seat with design changes. We are issuing this AD to prevent the passenger seats from failing during emergency landing conditions when high inertial loadings occur. Passenger seat failure may result in occupant injury.
This AD becomes effective on October 24, 2006.
As of October 24, 2006, the Director of the Federal Register approved the incorporation by reference of certain publications listed in the regulation.
For service information identified in this AD, contact Raytheon Aircraft Company, P.O. Box 85, Wichita, Kansas 67201; telephone: (800) 625-7043.

On May 15, 2006, we issued a proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to include an AD that would apply to certain RAC Model B300 airplanes. This proposal was published in the Federal Register as a notice of proposed rulemaking (NPRM) on May 19, 2006 (71 FR 29090). The NPRM proposed to require you to modify the cabin passenger seats by installing a modification kit on each passenger seat, removing the existing TSO label, and re-identifying each modified passenger seat assembly with a new part number.
We provided the public the opportunity to participate in developing this AD. We received no comments on the proposal or on the determination of the cost to the public.
We have carefully reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed except for minor editorial corrections. We have determined that these minor corrections:
- Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and
- Do not add any additional burden upon the public than was already proposed in the NPRM.
Costs of Compliance
We estimate that this AD affects 292 airplanes in the U.S. registry.
We estimate the following costs to do the modification:
|Labor cost||Parts cost (per seat)||Total cost per airplane (per seat)||Total cost on U.S. operators|
|3 work-hours (per seat) × $80 per hour = $240||$1,500||$1,740||$2,387,280. The number of passenger seats per airplane may vary. We estimate a total of 1,372 seats in the entire fleet.|
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 AD.
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 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 summary of the costs to comply with this AD (and other information as included in the Regulatory Evaluation) and placed it in the AD Docket. You may get a copy of this summary by sending a request to us at the address listed under ADDRESSES. Include “Docket No. FAA-2005-22103; Directorate Identifier 2005-CE-42-AD” in your request.Start List of Subjects
