**SUPPLEMENTARY INFORMATION :** 

Discussion

On March 27, 2008, we issued AD 2008–07–10, Amendment 39–15451 (73 FR 18706, April 7, 2008), for certain Hawker Beechcraft Corporation Models B200, B200GT, B300, and B300C airplanes. That AD requires fabricating and installing a placard incorporating


### 78597 Federal Register / Vol. 75, No. 241 / Thursday, December 16, 2010 / Rules and Regulations

information that limits operation when there is known or forecast icing and requires replacing a section of the pneumatic supply tube for the tail deice system with a new tube of a different material. That AD resulted from reports of collapsed tail deice boot pneumatic supply tubes. We issued that AD to prevent collapsed pneumatic supply tubes, which could result in failure of the tail deice boots to operate. This failure could lead to loss of control in icing conditions.

Actions Since AD Was Issued

Since we issued AD 2008–07–10, we received reports of two failures of the pneumatic supply tube for the tail deice system outside the area covered by AD 2008–07–10 on an affected Model B300 airplane and on an affected Model B300C airplane.

Relevant Service Information

We reviewed Hawker Beechcraft Mandatory Service Bulletin SB 30–3889, Rev. 1, dated October 2010. The service information describes procedures for replacing the entire length of the pneumatic supply tube for the tail deice system with a new tube of a different material. FAA’s Determination We are issuing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. AD Requirements

This AD requires accomplishing the actions specified in the service information described previously. FAA’s Justification and Determination of the Effective Date

An unsafe condition exists that requires the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because this condition could result in failure of the tail deice boots to operate. This failure could lead to loss of control in icing conditions. Therefore, we find 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.

Comments Invited

This AD is a final rule that involves requirements affecting flight safety, and we did not provide you with notice and an opportunity to provide your comments before it becomes effective. However, we invite you to send any written data, views, or arguments about this AD. Send your comments to an address listed under the **ADDRESSES** section. Include the docket number FAA–2010–1242 and directorate identifier 2010–CE–062–AD at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD because 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 about this AD.
Costs of Compliance

We estimate that this AD affects 90 airplanes of U.S. registry.

We estimate the following costs to comply with this AD:



### E STIMATED 

### C OSTS

Action Labor Cost Parts cost Cost per product Cost on U.S. operators

Fabricate placard (retained action from AD 2008–

07–10). 1 work-hour × $85 per hour = $85. Not applicable .................. $85 $7,650

Replace entire length of the pneumatic supply tube

for the tail de-ice system. 15 work-hours × $85 per hour = $1,275. $100 ................................. $1,375 $123,750

According to the manufacturer, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate. 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

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 DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979),

(3) Will not affect intrastate aviation in Alaska, and

(4) 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.

**SUPPLEMENTARY INFORMATION :** 
Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on October 13, 2010 (75 FR 62716), and proposed to supersede AD 2004–03–29, Amendment 39–13473 (69 FR 6553; February 11, 2004) and AD 2008–14–12, Amendment 39–15607 (73 FR 40951; July 17, 2008). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states that:

To prevent possible in-flight failure of the vertical stabiliser, leading to loss of control of the aircraft * * *

Replace the vertical stabiliser with P/N 08– 32005–2 by accomplishing modification PAC/FU/0345 in accordance with the instructions in Pacific Aerospace Limited Mandatory SB No. PACSB/FU/094 issue 1 dated 14 August 2008 * * * The MCAI requires replacement of the vertical stabilizer with a new design that incorporates a forward spar and is a failsafe structure. You may obtain further information by examining the MCAI in the AD docket.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public.

Conclusion

We reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed.

Differences Between This AD and the MCAI or Service Information

We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information.

We might also have required different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are highlighted in a NOTE within the AD. Costs of Compliance

We estimate that this AD will affect 3 products of U.S. registry. We alsoestimate that it will take about 1 workhour per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour.

Based on these figures, we estimate the cost of this AD to the U.S. operators to be $255 or $85 per product.

In addition, we estimate that it would take about 10.5 work-hours and require parts costing $14,375 to comply with the replacement requirements of this proposed AD.

Based on these figures, we estimate the replacement cost of this AD to the U.S. operators to be $45,802.50, or $15,267.50 per product. 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 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
