AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for the 

products listed above. This proposed 

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: 

Service experience has shown that fracture 

of the timing chain has occurred due to chain 

wear. This condition, if not corrected, could 

lead to in-flight cases of engine shutdown. 

We are proposing this AD to prevent 

engine in-flight shutdown leading to 

loss of control of the airplane by 

requiring life limits for the timing chain. 

DATES: We must receive comments on 

this proposed AD by December 13, 

2010. 

ADDRESSES: You may send comments by 

any of the following methods:

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– 

0136, dated June 30, 2010 (referred to 

after this as ‘‘the MCAI’’), to correct an 

unsafe condition for the specified 

products. The MCAI states: 

Service experience has shown that fracture 

of the timing chain has occurred due to chain 

wear. This condition, if not corrected, could 

lead to in-flight cases of engine shutdown. 

Engine experience shows that the design 

of the timing chain does not have the 

expected durability as evidenced by 

accelerated, premature wear, causing 

chain fracture resulting in engine inflight shutdown. The chain link pins 

and link plates become weakened and 

break from wear caused by hard sooty 

particles that are by-products of 

combustion. The link wear also 

lengthens the chain causing camshaft 

sprocket wear. Replacing the timing 

chain at the compliance times in this 

AD will help to avoid chain failure, 

which would cause engine shutdown. 

You may obtain further information 

by examining the MCAI in the AD 

docket. 

Relevant Service Information 

Thielert Aircraft Engines GmbH has 

issued Service Bulletin No. TM TAE 

125–1010 P1, Revision 2, dated May 26, 

2010. The actions described in this 

service information are intended to 

correct the unsafe condition identified 

in the MCAI. 

FAA’s Determination and Requirements 

of This Proposed 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 

proposing this AD because we evaluated 

all information provided by EASA and 

determined the unsafe condition exists 


wwoods2 on DSK1DXX6B1PROD with PROPOSALS_PART 1
Federal Register / Vol. 75, No. 208 / Thursday, October 28, 2010 / Proposed Rules 66343 

and is likely to exist or develop on other 

products of the same type design. This 

proposed AD would require initial 

replacement of the timing chain on the 

TAE 125–02–99 and TAE 125–02–114 

reciprocating engines listed by serial 

number in Table 1 of the proposed AD, 

and thereafter, repetitive replacements 

of the timing chain on all TAE 125–02– 

99 and TAE 125–02–114 reciprocating 

engines. 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 112 engines installed on 

airplanes of U.S. registry. We also 

estimate that it would take about 8 

work-hours per product to comply with 

this proposed AD. The average labor 

rate is $85 per work-hour. Required 

parts would cost about $162 per engine. 

Based on these figures, we estimate the 

cost of the proposed AD on U.S. 

operators to be $94,304. 

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 proposed AD 

would not have federalism implications 

under Executive Order 13132. This 

proposed AD would 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 proposed regulation: 

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 proposed AD and placed it in the 

AD docket.

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part 

39 as follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

2. The FAA amends § 39.13 by adding 

the following new AD: 

Thielert Aircraft Engines GmbH: Docket No. 

FAA–2010–0892; Directorate Identifier 

2010–NE–32–AD. 

Comments Due Date 

(a) We must receive comments by 

December 13, 2010. 

Affected Airworthiness Directives (ADs) 

(b) None. 

Applicability 

(c) This AD applies to Thielert Aircraft 

Engines GmbH models TAE 125–02–99 and 

TAE 125–02–114 reciprocating engines 

installed in, but not limited to, Cessna 172 

and (Reims-built) F172 series (European 

Aviation Safety Agency (EASA) 

Supplemental Type Certificate (STC) No. 

EASA.A.S.01527); Piper PA–28 series (EASA 

STC No. EASA.A.S. 01632); APEX (Robin) 

DR 400 series (EASA STC No. A.S.01380); 

and Diamond Aircraft Industries Models DA 

40, DA 42, and DA 42M NG airplanes. 

Reason 

(d) 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: 

Service experience has shown that fracture 

of the timing chain has occurred due to chain 

wear. This condition, if not corrected, could 

lead to in-flight cases of engine shutdown. 

We are issuing this AD to prevent engine 

in-flight shutdown leading to loss of control 

of the airplane by requiring life limits for the 

timing chain. 

Actions and Compliance 

(e) Unless already done, do the following 

actions. 

Initial Replacement of Timing Chain 

(1) For engines with serial numbers (S/Ns) 

listed in Table 1 of this AD, replace the 

timing chain within 600 flight hours-sincenew, or no later than 55 flight hours after the 

effective date of this AD, whichever occurs 

later. 

TABLE 1—S/NS OF ENGINES AFFECTED BY THE COMPLIANCE TIME IN

PARAGRAPH (E)(1) OF THIS AD

(2) For engines with S/Ns not listed in 

Table 1 of this AD, replace the timing chain 

within 910 flight hours-since-new, or no later 

than 55 flight hours after the effective date 

of this AD, whichever occurs later. 

Repetitive Replacements of Timing Chains 

for All TAE 125–02–99 and TAE 125–02–114 

Engines 

(3) Thereafter, for all TAE 125–02–99 and 

TAE 125–02–114 engines, repetitively 

replace the timing chain within every 

additional 910 flight hours. 

(4) Guidance on replacing the timing chain 

can be found in Thielert Aircraft Engines 

GmbH Service Bulletin No. TM TAE 125– 

1010 P1, Revision 2, dated May 26, 2010. 

FAA AD Differences 

(f) This AD differs from the MCAI and/or 

service information, which require initial 

replacement of the timing chain for the 

engines listed in paragraph (e)(1) above 

within either the next 110 flight hours or at 

the next maintenance, whichever occurs first, 

for those engines having accumulated 

between 500 and 600 flight hours time-sincenew. The reason for the difference is to 

ensure that the compliance requirements for 

all engines in paragraph (e)(1) above are 

consistent. 

Alternative Methods of Compliance 

(AMOCs) 

(g) The Manager, Engine Certification 

Office, FAA, has the authority to approve

contact the FAA’s Office of Rulemaking, 

(202) 267–9677, for a copy of Advisory 

Circular No. 11–2A, Notice of Proposed 

Rulemaking Distribution System, which 

describes the application procedure. 

History 

In May 2010, the FAA was notified by 

the Mexican Government that the 

Penasco VOR in Mexico had been 

relocated. This proposed action is 

necessary to realign Jet Route J–93 with 

the revised location of the Penasco VOR. 

The Proposal 

The FAA is proposing an amendment 

to Title 14 Code of Federal Regulations 

(14 CFR) part 71 to amend J–93 in 

California, between the Julian VORTAC 

and the ASUTA intersection along the 

United States/Mexican Border, by 

realigning the route with the revised 

locations of the Penasco VOR located in 

Mexico. 

Jet routes are published in paragraph 

2004 of FAA Order 7400.9U, dated 

August 18, 2010, and effective 

September 15, 2010, which is 

incorporated by reference in 14 CFR 

71.1. The jet routes listed in this 

document will be published 

subsequently in the order. 

The FAA has determined that this 

proposed regulation only involves an 

established body of technical 

regulations for which frequent and 

routine amendments are necessary to 

keep them operationally current. 

Therefore, this proposed regulation: (1) 

Is not a ‘‘significant regulatory action’’ 

under Executive Order 12866; (2) is not 

a ‘‘significant rule’’ under Department of 

Transportation (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 is 

certified that this proposed rule, when 

promulgated, will not have a significant 

economic impact on a substantial 

number of small entities under the 

criteria of the Regulatory Flexibility Act. 

The FAA’s authority to issue rules 

regarding aviation safety is found in 

Title 49 of the United States Code. 

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.
