in Accordance With Supplemental 

Type Certificate (STC) SA2271SW 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Hawker Beechcraft Corporation Model 

BH.125 series 600A airplanes and 

Model HS.125 series 700A airplanes. 

This AD requires inspecting the wiring 

diagrams containing the cockpit blowers 

and comparing with the current airplane 

configuration, and reworking the wiring 

if necessary. This AD results from a 

report indicating that a blower motor of 

the cockpit ventilation and avionics 

cooling system seized up and gave off 

smoke. We are issuing this AD to 

prevent smoke and fumes in the cockpit 

in the event that a blower motor seizes 

and overheats due to excessive current 

draw. 

DATES: This AD is effective May 14, 

2009. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of May 14, 2009.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an airworthiness 

directive (AD) that would apply to 

certain Hawker Beechcraft Corporation 

Model BH.125 series 600A airplanes 

and Model HS.125 series 700A 

airplanes. That NPRM was published in 

the Federal Register on November 26, 

2008 (73 FR 71959). That NPRM 

proposed to require inspecting the 

wiring diagrams containing the cockpit 

blowers and comparing with the current 

airplane configuration, and reworking 

the wiring if necessary. 

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. 

Explanation of Change to Final Rule 

We have changed the product 

identification line to specify the 

airplane type certificate holder. 

Conclusion 

We reviewed the relevant data and 

determined that air safety and the 

public interest require adopting the AD 

with the change described previously. 

We also determined that this change 

will not increase the economic burden 

on any operator or increase the scope of 

the AD. 

Costs of Compliance 

We estimate that this AD affects 40 

airplanes of U.S. registry. We also 

estimate that it takes about 1 work-hour 

per product to comply with this AD. 

The average labor rate is $80 per workhour. Based on these figures, we 

estimate the cost of this AD to U.S. 

operators to be $3,200, or $80 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.

Federal Register / Vol. 74, No. 67 / Thursday, April 9, 2009 / Rules and Regulations 16117 

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), 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. 

You can find our regulatory 

evaluation and the estimated costs of 

compliance in the AD Docket.

accordance with Supplemental Type 

Certificate SA2271SW. 

Unsafe Condition 

(d) This AD results from a report indicating 

that a blower motor of the cockpit ventilation 

and avionics cooling system seized up and 

gave off smoke. We are issuing this AD to 

prevent smoke and fumes in the cockpit in 

the event that a blower motor seizes and 

overheats due to excessive current draw. 

Compliance 

(e) Comply with this AD within the

accordance with the Accomplishment 

Instructions of Hawker Beechcraft Mandatory 

Service Bulletin SB 24–3850, dated January 

2008; except as provided by paragraph (g) of 

this AD.

does not match the applicable cockpit blower 

wiring diagrams, before further flight, rework 

the wiring using a method approved by the 

Manager, Special Certification Office, ASW– 

190, Rotorcraft Directorate, FAA. For the 

determination to be approved by the 

Manager, Special Certification Office, as 

required by this paragraph, the Manager’s 

approval letter must specifically refer to this 

AD.

No Submission of Certain Information 

(g) Although Hawker Beechcraft Mandatory 

Service Bulletin SB 24–3850, dated January 

2008, specifies to submit certain information 

to the manufacturer, this AD does not 

include that requirement.

Airworthiness Directives; Liberty 

Aerospace Incorporated Model XL–2 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Liberty Aerospace Incorporated Model 

XL–2 airplanes. This AD requires you to 

repetitively inspect the exhaust muffler 

for cracks and to replace the exhaust 

muffler when cracks are found. This AD 

is the result of reports that cracks have 

been found in the exhaust muffler 

during maintenance and service 

inspections. We are issuing this AD to 

detect and correct cracks in the exhaust 

muffler, which could result in carbon 

monoxide entering the cabin through 

the heating system. Carbon monoxide 

entering into the airplane cabin could 

lead to incapacitation of the pilot.
