Rebuilt Turbochargers 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for certain 

Kelly Aerospace Energy Systems, LLC 

(KAES) rebuilt turbochargers. This AD 

requires removal from service of certain 

part number (P/N) and serial number (S/ 

N) rebuilt turbochargers. This AD 

results from three reports of infant 

mortality turbine wheel failure in 

rebuilt turbochargers, since June of 

2007. We are issuing this AD to prevent 

separation or seizure of the turbocharger 

turbine, which could result in full or 

partial engine power loss, loss of engine 

oil, and smoke in the airplane cabin. 

DATES: This AD becomes effective April 

19, 2010. The Director of the Federal 

Register approved the incorporation by 

reference of certain publications listed 

in the regulations as of April 19, 2010. 

We must receive any comments on 

this AD by June 1, 2010.

SUPPLEMENTARY INFORMATION: In October 

2009, we were made aware by KAES 

that since June 2007, three 

turbochargers rebuilt by KAES have 

failed. Two had turbine wheel head 

separation and the third had a turbine 

shaft seizure. Investigation revealed that 

a steel wire brush was used to remove 

the accumulated coking that had built 

up on these turbine wheels being 

reclaimed for re-use in rebuilt 

turbochargers. This procedure created a 

rough surface finish on the turbine 

wheel shaft that exceeded allowable 

limits. The rough surface finish can 

disrupt the required formation of a 

hydrodynamic layer of oil between the 

shaft and mating bearings. This 

condition, if not corrected, could result 

in separation or seizure of the 

turbocharger turbine, which could result 

in full or partial engine power loss, loss 

of engine oil, and smoke in the airplane 

cabin. 

Relevant Service Information 

We have reviewed and approved the 

technical contents of Kelly Aerospace 

Energy Systems, LLC Service Bulletin 

(SB) No. 039 A, dated February 10, 

2010. That SB identifies the rebuilt 

turbochargers by P/N and S/N that are 

suspect of having a rough shaft surface 

finish exceeding allowable limits. 

FAA’s Determination and Requirements 

of This AD 

The unsafe condition described 

previously is likely to exist or develop 

on other KAES rebuilt turbochargers of 

the same type design. For that reason, 

we are issuing this AD to prevent 

separation or seizure of the turbocharger 

turbine, which could result in full or 

partial engine power loss, loss of engine 

oil, and smoke in the airplane cabin. 

This AD requires removal from service 

of certain P/N and S/N rebuilt 

turbochargers. You must use the service 

information described previously to 

determine what S/N rebuilt 

turbochargers are affected by this AD. 

FAA’s Determination of the Effective 

Date 

Since an unsafe condition exists that 

requires the immediate adoption of this 

AD, we have found that notice and 

opportunity for public comment before 

issuing this AD 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 

was not preceded by notice and an 

opportunity for public comment; 

however, we invite you to send us any 

written relevant data, views, or 

arguments regarding this AD. Send your 

comments to an address listed under 

ADDRESSES. Include ‘‘AD Docket No. 

FAA–2009–1259; Directorate Identifier 

2009–NE–41–AD’’ in the subject line of 

your comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of the rule that might suggest a 

need to modify it. 

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 with FAA

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 the 

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.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are revising an existing 

airworthiness directive (AD) for the 

products listed above. This AD results 

from mandatory continuing 

airworthiness information (MCAI) 

issued by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: 

During production of Arriel 1 and Arriel 2 

Power Turbine (PT) wheels, geometric nonconformances on blade fir tree roots have 

been detected by Turbome ́ca. Potentially 

non-conforming PT blades have been traced 

as having been installed on Module M04 (PT) 

listed in Mandatory Service Bulletin (MSB) 

A292 72 0827 for Arriel 1 engines and A292 

72 2833 for Arriel 2 engines. 

The geometric non-conformities of the 

blades may potentially lead to a reduction in 

the fatigue resistance of PT blades to a lower 

level than their authorized in service use 

limit. This reduction of fatigue resistance can 

potentially result in blade release, which 

could cause an uncommanded in-flight 

shutdown. 

We are issuing this AD to prevent 

release of PT blades, which could result 

in an uncommanded in-flight shutdown 

and emergency autorotation landing. 

DATES: This AD becomes effective May 

7, 2010. The Director of the Federal 

Register approved the incorporation by 

reference of certain publications listed 

in this AD as of May 7, 2010.

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 December 23, 2009 (74 FR 

68194). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

Since issuance of initial version of AD 

2009–0112 additional information is 

available: 

—The list of Modules M04 concerned by the 

restriction of the cycle use limit of these PT 

blades has been updated again: The serial 

numbers of Modules M04 which have been 

retrofitted are crossed out. However, no 

new affected Modules M04 have been 

identified. See figure 1 of the referenced 

Turbome ́ca MSB. 

—Additional testing and analysis had been 

carried out by Turbome ́ca which allows 

increasing the cyclic use limit of these PT 

blades to 5 000 flight cycles. 

Therefore this AD revises AD 2009–0112 

and requires establishing the cyclic use limit 

of these PT blades to 5 000 flight cycles. 

For PT blades having reached a number of 

flight cycles superior or equal to 5 000, 

removal of Module M04, or PT wheel 

assembly, or PT blades is required prior to 

next flight. 

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 required different actions in this AD 

from those in the MCAI in order to 

follow FAA policies. Any such 

differences are described in a separate 

paragraph of the AD. These 

requirements take precedence over the 

actions copied from the MCAI. 

Costs of Compliance 

Based on the service information, we 

estimate that this AD will affect about 

10 products of U.S. registry. We also 

estimate that it will take about 8 workhours per product to comply with this 

AD. The average labor rate is $80 per 

work-hour. Required parts will cost 

about $43,000 per product. Based on
