Airworthiness Directives; Hamilton 

Sundstrand Power Systems T–62T– 

46C12 Auxiliary Power Units 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for 

Hamilton Sundstrand Power Systems 

T–62T–46C12 auxiliary power units 

(APUs). This AD requires upgrading the 

software in the APU full-authority 

digital controller (FADEC) from software 

version 02.01.000 to version 03.00.000. 

This AD results from two reports of 

APU compartment explosions due to 

over-fueling of the APU at low 

revolutions-per-minute during the start 

sequence. We are issuing this AD to 

prevent over-fueling of the APU during 

the start sequence, which could lead to 

fuel explosions, injury, and damage to 

the APU and the airplane. 

DATES: This AD becomes effective 

November 20, 2009. The Director of the 

Federal Register approved the 

incorporation by reference of certain 

publications listed in the regulations as 

of November 20, 2009. 

ADDRESSES: You can get the service 

information identified in this AD from

Publications, One Hamilton Road, Mail

SUPPLEMENTARY INFORMATION: The FAA 

proposed to amend 14 CFR part 39 with 

a proposed AD. The proposed AD 

applies to Hamilton Sundstrand Power 

Systems T–62T–46C12 APUs. We 

published the proposed AD in the 

Federal Register on April 13, 2009 (74 

FR 16811). That action proposed to 

require upgrading the software in the 

APU FADEC from software version 

02.01.000 to version 03.00.000. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http:// 

www.regulations.gov; or in person at the 

Docket Operations office between 9 a.m. 

and 5 p.m., Monday through Friday, 

except Federal holidays. The AD docket 

contains this AD, the regulatory 

evaluation, any comments received, and 

other information. The street address for 

the Docket Operations office (telephone 

(800) 647–5527) is provided in the 

ADDRESSES section. Comments will be 

available in the AD docket shortly after 

receipt. 

Comments 

We provided the public the 

opportunity to participate in the 

development of this AD. We have 

considered the comment received. 

One commenter states that we should 

reference Revision 2 of Hamilton 

Sundstrand Power Systems Service 

Bulletin (SB) No. 4503067–49–12 

instead of referencing Revision 1 of that 

SB. Revision 1 had a technical error in 

it that prevented loading the software 

change. 

We agree. We changed the AD to 

reference Revision 2 of the SB. 

Conclusion 

We have carefully reviewed the 

available data, including the comment 

received, and determined that air safety 

and the public interest require adopting 

the AD with the change described 

previously. We have determined that 

this change will neither increase the 

economic burden on any operator nor 

increase the scope of the AD. 

Costs of Compliance 

We estimate that this AD will affect 

59 Hamilton Sundstrand Power Systems 

T–62T–46C12 APUs installed on 

airplanes of U.S. registry. We also 

estimate that it will take about three 

work-hours per APU to perform the 

actions, and that the average labor rate 

is $80 per work-hour. There is no 

required part cost. Based on these 

figures, we estimate the total cost of the 

AD to U.S. operators to be $14,160. 

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 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. 

We prepared a summary of the costs 

to comply with this AD and placed it in 

the AD Docket. You may get a copy of 

this summary at the address listed 

under ADDRESSES.

Amendment of Class D and Class E 

Airspace; Topeka, KS 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: This action amends Class D 

and Class E airspace at Forbes Field 

Airport, Topeka, KS. Additional 

controlled airspace is necessary to 

accommodate new Standard Instrument 

Approach Procedures (SIAPs) at Forbes 

Field Airport, Topeka, KS. This action 

also incorporates the Class E extensions 

to Class D airspace at Forbes Field 

Airport into the Class D surface area. 

The FAA is taking this action to 

enhance the safety and management of 

Instrument Flight Rule (IFR) operations 

at Forbes Field Airport. 

DATES: 0901 UTC, December 17, 2009. 

The Director of the Federal Register 

approves this incorporation by reference 

action under 1 CFR Part 51, subject to 

the annual revision of FAA Order 

7400.9 and publication of conforming 

amendments.

SUPPLEMENTARY INFORMATION: 

History 

On July 30, 2009, the FAA published 

in the Federal Register a notice of 

proposed rulemaking to amend Class D 

and Class E airspace at Topeka, KS (74 

FR 37968, Docket No. FAA–2009–0404). 

Interested parties were invited to 

participate in this rulemaking effort by 

submitting written comments on the 

proposal to the FAA. No comments 

were received. Class D airspace 

designations are published in paragraph 

5000 of FAA Order 7400.9T signed 

August 27, 2009, and effective 

September 15, 2009, which is 

incorporated by reference in 14 CFR 

71.1. Class E airspace designations are 

published in paragraph 6002 of FAA 

Order 7400.9T signed August 27, 2009, 

and effective September 15, 2009, which 

is incorporated by reference in 14 CFR 

71.1. The Class D and Class E airspace 

designations listed in this document 

will be published subsequently in the 

Order. 

The Rule 

This action amends Title 14 Code of 

Federal Regulations (14 CFR) Part 71 by 

amending Class D and Class E airspace 

at Forbes Field Airport, Topeka, KS, for 

the safety and management of IFR 

operations at the airport. The Class E 

surface area designated as an extension 

to a Class D surface area will be added 

to the Class D airspace area. 

The FAA has determined that this 

regulation only involves an established 

body of technical regulations for which 

frequent and routine amendments are 

necessary to keep them operationally 

current. Therefore, this regulation: (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) 

does not warrant preparation of a 

regulatory evaluation as the anticipated 

impact is so minimal. Since this is a 

routine matter that will only affect air 

traffic procedures and air navigation, it
