SUMMARY: We are adopting a new 

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: 

In-flight shutdown incidents have been 

reported on airplanes equipped with TAE 

125 engines. Preliminary investigations 

showed that it was mainly the result of 

nonconforming disc springs (improper heat 

treatment) used in a certain production batch 

of the clutch. 

We are issuing this AD to prevent 

engine in-flight shutdown leading to 

loss of control of the airplane. 

DATES: This AD becomes effective 

September 9, 2010. 

We must receive comments on this 

AD by September 24, 2010. 

The Director of the Federal Register 

approved the incorporation by reference 

of Thielert Aircraft Engines GmbH

SUPPLEMENTARY INFORMATION: 

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA AD 2010– 

0111–E, dated June 10, 2010 (corrected 

June 11, 2010) (referred to after this as 

‘‘the MCAI’’), to correct an unsafe 

condition for the specified products. 

The MCAI states: 

In-flight shutdown incidents have been 

reported on airplanes equipped with TAE 

125 engines. Preliminary investigations 

showed that it was mainly the result of 

nonconforming disc springs (improper heat 

treatment) used in a certain production batch 

of the clutch.

Federal Register / Vol. 75, No. 164 / Wednesday, August 25, 2010 / Rules and Regulations 52241 

You may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

TAE has issued SB No. TM TAE 125– 

0021, dated June 9, 2010, and SB No. 

TM TAE 125–1011 P1, dated June 9, 

2010. The actions described in these 

SBs are intended to correct the unsafe 

condition identified in the MCAI. 

FAA’s Determination and Requirements 

of This AD 

This product has been approved by 

the aviation authority of Germany, and 

is approved for operation in the United 

States. Pursuant to our bilateral 

agreement with Germany, they have 

notified us of the unsafe condition 

described in the MCAI and service 

information referenced above. We are 

issuing this AD because we evaluated 

all information provided by EASA and 

determined the unsafe condition exists 

and is likely to exist or develop on other 

products of the same type design. This 

AD requires replacement of affected 

clutch assemblies. 

Differences Between the 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 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. 

FAA’s 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 of the need for operators to 

comply with some of the AD actions 

before further flight. Therefore, we 

determined that notice and opportunity 

for public comment before issuing this 

AD are impracticable and that good 

cause exists for making this amendment 

effective in fewer than 30 days. 

Comments Invited 

This AD is a final rule that involves 

requirements affecting flight safety, and 

we did not precede it by notice and 

opportunity for public comment. We 

invite you to send any written relevant 

data, views, or arguments about this AD. 

Send your comments to an address 

listed under the ADDRESSES section. 

Include ‘‘Docket No. FAA–2010–0683; 

Directorate Identifier 2010–NE–25–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 with FAA 

personnel concerning this AD. Using the 

search function of the Web site, anyone 

can find and read the comments in any 

of our dockets, including, if provided, 

the name of the individual who sent the 

comment (or signed the comment on 

behalf of an association, business, labor 

union, etc.). You may review the DOT’s 

complete Privacy Act Statement in the 

Federal Register published on April 11, 

2000 (65 FR 19477–78). 

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 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 regulatory evaluation 

of the estimated costs to comply with 

this AD and placed it in the AD docket.

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule; request for 

comments. 

SUMMARY: The FAA is superseding an 

existing airworthiness directive (AD) 

that applies to all Model 737–600, –700, 

–700C, –800, –900, and –900ER series 

airplanes. The existing AD currently 

requires, for certain airplanes, a onetime detailed inspection of the inboard 

and outboard aft attach lugs of the left 

and right elevator tab control 

mechanisms for discrepancies, and 

replacement of any discrepant elevator 

tab control mechanism. For certain 

other airplanes, the existing AD requires 

that the inspections be done 

repetitively. Replacing the elevator tab 

control mechanism with a new Boeingbuilt mechanism terminates the 

repetitive inspections in the existing 

AD. This new AD requires that modified 

repetitive inspections be done on all 

airplanes, regardless of accomplishment 

of the terminating action specified in 

the existing AD. This AD results from 

reports of failure of the aft attach lugs 

on the elevator tab control mechanisms, 

which resulted in severe elevator 

vibration. This AD also results from 

reports of gaps in elevator tab control 

mechanisms and analysis that 

additional elevator tab control 

mechanisms might have bearings that 

will come loose. We are issuing this AD 

to detect and correct discrepancies in 

the aft attach lugs of the elevator tab 

control mechanism, which could result 

in elevator and tab vibration. 

Consequent structural failure of the 

elevator or horizontal stabilizer could 

result in loss of structural integrity and 

aircraft control. 

DATES: This AD becomes effective 

September 9, 2010. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of September 9, 2010. 

On April 29, 2010 (75 FR 21499, April 

26, 2010), the Director of the Federal 

Register approved the incorporation by
