AD 2010-17-15

We are adopting a new airworthiness directive (AD) for certain Hawker Beechcraft Corporation Model 390 airplanes. This AD requires you to inspect for installation of certain serial number (S/N) starter generators and replace the starter generator if one with an affected serial number is found. This AD results from reports that starter generators with deficient armature insulating materials may have been installed on certain airplanes. We are issuing 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.

Final rule.

2010-17-15 Hawker Beechcraft Corporation (Type Certificate No. A00010WI Previously Held By Raytheon Aircraft Company): Amendment 39-16407; Docket No. FAA-2010-0523; Directorate Identifier 2010-CE- 018-AD.

Effective Date

(a) This AD becomes effective on September 29, 2010.

Affected ADs

(b) None.

Applicability

(c) This AD applies to Model 390 airplanes, serial numbers RB-4 through RB-257, RB-259 through RB-265, RB-268, and RB-269, that are certificated in any category.

Subject

(d) Air Transport Association of America (ATA) Code 24: Electric Power.

Unsafe Condition

(e) This AD results from reports that starter generators with deficient armature insulating materials may have been installed on certain airplanes. We are issuing this AD to detect and replace starter generators with deficient armature insulating materials. This condition could result in the loss of operation of one or both starter generators with consequent loss of all non-batteryelectrical power.

Compliance

(f) To address this problem, you must do the following, unless already done:

Discussion

On May 14, 2010, 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 serial number starter generators where deficient armature insulating materials may have been installed on Hawker Beechcraft Corporation Model 390 airplanes. This proposal was published in the Federal Register as a notice of proposed rulemaking (NPRM) on May 21, 2010 (FR 75 28506). The NPRM proposed to detect and replace starter generators with deficient 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.

Comments

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.

Conclusion

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 213 airplanes in the U.S. registry.
We estimate the following costs to do the inspection:

Labor Cost
Parts Cost
Total Cost Per Airplane
Total Cost on U.S. 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 inspection. We have no way of determining the number of airplanes that may need this replacement:

Labor Cost
Parts Cost
Total Cost Per Airplane
10 work-hours (5 work-hours per side) X $85 per hour =$850
$4,069 per side = $8,138
$8,988

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.

Regulatory Findings

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-2010-0523; Directorate Identifier 2010-CE-018-AD'' in your request.
