Certificate No. A00010WI Previously Held by Raytheon Aircraft Company)

Model 390 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 Hawker Beechcraft Corporation Model 390 airplanes. This proposed AD would require inspecting for installation of certain serial number (S/N) starter generators and replacing the starter generator if one with an affected serial number is found. This proposed AD results from reports that starter generators with deficient armature insulating materials may have been installed on certain airplanes. We are proposing this AD to detect and replace starter generators with defective armature insulating materials. This condition could result in the loss of operation of one or both starter generators with consequent loss of all non-battery electrical power.

DATES: We must receive comments on this proposed AD by July 6, 2010.

ADDRESSES: Use one of the following addresses to comment on this proposed AD:

SUPPLEMENTARY INFORMATION:

Comments Invited

We invite you to send any written relevant data, views, or arguments regarding this proposed AD. Send your comments to an address listed under the ADDRESSES section. Include the docket number, ``FAA- 2010-0523; Directorate Identifier 2010-CE-018-AD'' at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of the proposed

AD. We will consider all comments received by the closing date and may amend the proposed AD in light of those comments.

We will post all comments we receive, without change, to http:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive concerning this proposed AD.

Discussion

We have received reports that certain serial number starter generators with deficient armature insulating materials may have been installed on Hawker Beechcraft Corporation Model 390 airplanes. Starter generators with deficient armature fabrication may result in loss of operation of one or both starter generators in flight.

This condition could result in the loss of operation of one or both starter generators with consequent loss of all non-battery electrical power.

Relevant Service Information

We have reviewed Hawker Beechcraft Mandatory Service Bulletin SB 24-3963, issued May 2009, and AMETEK Advanced Industries, Inc.

Mandatory Service Bulletin--Number: 2009-0414, dated April 2009.

The service information describes procedures for:

Inspection for starter generators with serial numbers that may have the deficient armature materials; and

Removal and replacement of starter generators with the affected serial numbers.

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 an inspection for suspect starter generators and their replacement if found.

Costs of Compliance

We estimate that this proposed AD would affect 213 airplanes in the

U.S. registry.

We estimate the following costs to do the proposed inspection:

Total cost per

Total cost on U.S.

Labor cost

Parts cost

airplane

operators

.5 work-hour x $85 per hour = $42.50...... Not applicable..............

$42.50

$9,052.50

We estimate the following costs to do any necessary replacements that would be required based on the results of the proposed inspection.

We have no way of determining the number of airplanes that may need this replacement:

Total cost per

Labor cost

Parts cost

airplane

10 work-hours (5 work-hours per $4,069 per side =

$8,988 side) x $85 per hour = $850.

$8,138.

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.
