and T–62T–46C7A 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for 

Hamilton Sundstrand Power Systems 

(formerly Sundstrand Power Systems) 

auxiliary power units (APUs) models T–

62T–46C2, T–62T–46C2A, T–62T–46C3, 

T–62T–46C7, and T–62T–46C7A, with 

compressor impeller assembly, part 

number (P/N) 4502020 or 4502020A, 

installed. This AD requires removal 

from service of those compressor 

impeller assemblies at reduced service 

life limits. This AD results from two 

reports of uncontained failures of 

compressor impeller assemblies. We are 

issuing this AD to prevent an 

uncontained APU failure and damage to 

the airplane. 

DATES: This AD becomes effective 

December 14, 2005. 

ADDRESSES: You may examine the AD 

docket on the Internet at http:// 

dms.dot.gov or in Room PL–401 on the 

plaza level of the Nassif Building, 400 

Seventh Street, SW., Washington, DC.

fax (562) 627–5210. 

SUPPLEMENTARY INFORMATION: The FAA 

proposed to amend 14 CFR part 39 with 

a new AD, applicable to Hamilton 

Sundstrand Power Systems APUs 

models T–62T–46C2, T–62T–46C2A, T–

62T–46C3, T–62T–46C7, and T–62T–

46C7A, with compressor impeller 

assembly, part number (P/N) 4502020 or 

4502020A, installed. We published the 

proposed AD in the Federal Register on 

July 5, 2005 (70 FR 38625). We 

proposed to require removal from 

service of those compressor impeller 

assemblies at reduced service life limits. 

Examining the AD Docket 

You may examine the docket that 

contains the AD, any comments 

received, and any final disposition in 

person at the Docket Management 

Facility Docket Offices between 9 a.m. 

and 5 p.m., Monday through Friday, 

except Federal holidays. The Docket 

Office (telephone (800) 647–5227) is 

located on the plaza level of the 

Department of Transportation Nassif 

Building at the street address stated in 

ADDRESSES. Comments will be available 

in the AD docket shortly after the DMS 

receives them. 

Comments 

We provided the public the 

opportunity to participate in the 

development of this AD. We received no 

comments on the proposal or on the 

determination of the cost to the public. 

Conclusion 

We carefully reviewed the available 

data and determined that air safety and 

the public interest require adopting the 

AD as proposed. 

Costs of Compliance 

About 50 Hamilton Sundstrand Power 

Systems model T–62T APUs in the 

worldwide fleet are of the affected 

design. Eight APUs installed on 

airplanes of U.S. registry are affected by 

this AD. We estimate that it will take 

about 8 work hours to remove and 

install an APU, and that the average 

labor rate is $65 per work hour. A new 

or serviceable compressor impeller 

assembly, P/N 4502020 or 4502020A, 

may be installed provided it meets the 

cycles-since-new criteria in the 

compliance section of this AD. It will 

take about 55.5 hours to remove and 

replace affected compressor impeller 

assembly parts. New configuration 

replacement parts for each APU will 

cost about $36,587. Based on these 

figures, we estimate the total cost of the 

AD to U.S. operators, to remove, 

upgrade, and install the APUs to be 

$325,716. 

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 

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.

impeller assemblies from service before 

accumulating 500 additional cycles. 

(g) For APUs with compressor impeller 

assemblies that have fewer than 12,000 CSN 

on the effective date of this AD, remove

at or before accumulating 12,500 CSN. 

Alternative Methods of Compliance 

(h) The Manager, Los Angeles Aircraft 

Certification Office, has the authority to
