06-6590. Airworthiness Directives; Raytheon Aircraft Company Models C90A, B200, B200C, B300, and B300C Airplanes

AGENCY:

Federal Aviation Administration (FAA), Department of Transportation (DOT).

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

We propose to adopt a new airworthiness directive (AD) for certain Raytheon Aircraft Company (Raytheon) (formerly Beech) Models C90A, B200, B200C, B300, and B300C airplanes. This proposed AD would require you to inspect the flight controls for improper assembly or damage, and if any improperly assembled or damaged flight controls are found, take corrective action. This proposed AD results from a report of inspections of several affected airplanes with improperly assembled or damaged flight controls. We are proposing this AD to detect and correct improperly assembled or damaged flight controls, which could result in an unsafe condition by reducing capabilities of the flight controls and lead to loss of control of the airplane.

DATES:

We must receive comments on this proposed AD by September 29, 2006.

We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of the proposed AD.

Discussion

We have received a report from an FAA Manufacturing Inspection District Office that describes numerous nonconformities during the manufacture of Raytheon Models C90A, B200, B200C, B300, and B300C airplanes. These nonconformities affected the flight controls and included improper assembly and damage to the flight controls that could lead to loss of control of the airplane.

This condition, if not corrected, could result in an unsafe condition by reducing capabilities of the flight controls.

Relevant Service Information

We have reviewed Raytheon Aircraft Company Mandatory Service Bulletin Number SB 27-3761, Issued: February 2006.

The service information describes procedures for inspecting the flight control systems to ensure conformity with type design and correct the unsafe condition.

FAA's Determination and Requirements of the Proposed AD

We are proposing this AD because we evaluated all information and determined the unsafe condition described previously is likely to exist or develop on other products of the same type design. This proposed AD would require you to inspect the flight controls for improper assembly or damage, and if any improperly assembled or damaged flight controls are found, take corrective action.

Differences Between This Proposed AD and the Service Information

We are requiring all phases of the flight control system be inspected at one time. The service information as presented allows some sections of the system to go 800 hours time-in-service before they are scheduled for inspection. We feel this time is excessive to allow potential safety items and nonconformities to exist. We have determined that the proposed compliance time will not inadvertently ground the affected airplanes.

Costs of Compliance

We estimate that this proposed AD would affect 135 airplanes in the U.S. registry.

We estimate the following costs to do the proposed inspection:

Labor cost	Parts cost	Total cost per airplane	Total cost on U.S. operators
80 work-hours × $80 per hour = $6,400	Not Applicable	$6,400	$864,000

We have no way of determining the number of airplanes that may need any corrective action that would be required based on the results of the proposed inspection.

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 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 and placed it in the AD docket.

Examining the AD Docket

You may examine the AD docket that contains the proposed AD, the regulatory evaluation, any comments received, and other information on the Internet at http://dms.dot.gov;​; or in person at the Docket Management Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The Docket Office (telephone [phone]) is located at the street address stated in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt.
