AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments. 

SUMMARY: We are superseding an 

existing airworthiness directive (AD) for 

the products listed above. That AD 

currently requires fabricating and 

installing a placard incorporating 

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. This AD requires fabricating 

and installing a placard incorporating 

information that limits operation when 

there is known or forecast icing and 

requires replacing the entire length of 

the pneumatic supply tube for the tail 

deice system with a new tube of a 

different material. This AD was 

prompted by reports of two failures of 

the pneumatic supply tube for the tail 

deice system outside the area covered 

by AD 2008–07–10. We are issuing this 

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. 

DATES: This AD is effective December 

20, 2010. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of December 20, 2010. 

We must receive any comments on 

this AD by January 31, 2011.

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 


jlentini on DSKJ8SOYB1PROD with RULES
Federal Register / Vol. 75, No. 241 / Thursday, December 16, 2010 / Rules and Regulations 78597 

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: 

ESTIMATED COSTS

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 also 

estimate 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
