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 (MCAIs) 

issued by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAIs describe the unsafe 

condition as: 

As a consequence of occurrences and 

service experience, Thielert Aircraft Engines 

GmbH has introduced a new rail pressure 

control valve part number (P/N) 05–7320– 

E000702 and P/N 02–7320–04100R3 and has 

amended the Airworthiness Limitation 

Section (ALS) of the Operation & 

Maintenance Manual OM–02–02 to include a 

replacement of the rail pressure control 

valve. Failure of this part could result in inflight shutdowns of the engine(s). 

We are proposing this AD to prevent 

engine in-flight shutdown, possibly 

resulting in reduced control of the 

aircraft.

Discussion 

EASA, which is the Technical Agent 

for the Member States of the European 

Community, has issued AD 2008–0128, 

dated July 9, 2008, and AD 2008–0215, 

dated December 5, 2008 (referred to 

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

unsafe condition for the specified 

products. These MCAIs state: 

As a consequence of occurrences and 

service experience, Thielert Aircraft Engines 

GmbH has introduced a new rail pressure 

control valve P/N 05–7320–E000702 and 02– 

7320–04100R3 and has amended the ALS of 

the Operation & Maintenance Manual OM– 

02–02 to include a replacement of the rail 

pressure control valve. Failure of this part 

could result in in-flight shutdowns of the 

engine(s). 

You may obtain further information by 

examining the MCAIs in the AD docket. 

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, EASA has 

notified us of the unsafe condition 

described in the MCAI. We are 

proposing 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 

proposed AD would require initial and 

repetitive replacements of the rail 

pressure control valve. 

Differences Between This AD and the 

MCAIs or Service Information 

We have reviewed the MCAIs and 

related service information and, in 

general, agree with their substance. But 

we have found it necessary to reduce 

the initial compliance time for TAE 

125–02–99 engines from within 110 

flight hours to within 100 flight hours, 

and for TAE 125–01 engines from 

within the next 3 months to within 100 

flight hours. We also have found it 

necessary to reference a specific 

repetitive replacement compliance time 

for the rail pressure control valve of 

within every 600 flight hours. The 

MCAIs instruct the operators to follow 

Thielert Maintenance Manual, Chapter 

5, Airworthiness Limitations, for the 

repetitive compliance time. We have 

also found it necessary to exclude the 

repetitive inspections of the alternator 

on TAE 125–01 engines, as we consider 

these inspections as maintenance 

actions. We made these changes 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. 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 370 TAE 125–01 and TAE 

125–02–99 reciprocating engines 

installed on products of U.S. registry. 

We also estimate that it would take 

about 1.5 work-hours per engine to 

comply with this proposed AD. The 

average labor rate is $80 per work-hour. 

Required parts would cost about $500 

per engine. Based on these figures, we 

estimate the cost of the proposed AD for 

initial replacement, on U.S. operators to 

be $229,400. 

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–2009–0948; Directorate Identifier 2009– 

NE–30–AD. 

Comments Due Date 

(a) We must receive comments by 

November 18, 2009. 

Affected Airworthiness Directives (ADs) 

(b) None. 

Applicability 

(c) This AD applies to Thielert Aircraft 

Engines GmbH (TAE) models TAE 125–01 

and TAE 125–02–99 reciprocating engines 

installed in, but not limited to, Cessna 172 

and Reims-built) F172 series (EASA 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

Reason 

(d) As a consequence of occurrences and 

service experience, Thielert Aircraft Engines 

GmbH has introduced a new rail pressure 

control valve part number (P/N) 05–7320– 

E000702 and P/N 02–7320–04100R3 and has 

amended the Airworthiness Limitation 

Section (ALS) of the Operation & 

Maintenance Manual OM–02–02 to include a 

replacement of the rail pressure control 

valve. Failure of this part could result in inflight shutdowns of the engine(s). 

This AD results from mandatory continuing 

airworthiness information (MCAIs) issued by 

an aviation authority of another country to 

identify and correct an unsafe condition on 

an aviation product. We are issuing this AD 

to prevent engine in-flight shutdown, 

possibly resulting in reduced control of the 

aircraft. 

Actions and Compliance 

(e) Unless already done, do the following 

actions. 

TAE 125–02–99 Reciprocating Engines 

(1) For TAE 125–02–99 reciprocating 

engines, within 100 flight hours after the 


cprice-sewell on DSK2BSOYB1PROD with PROPOSALS
53440 Federal Register / Vol. 74, No. 200 / Monday, October 19, 2009 / Proposed Rules 

effective date of this AD, replace the existing

from within 110 flight hours to within 100 

flight hours, and for TAE 125–01 

reciprocating engines from within the next 3 

months to within 100 flight hours. 

(2) We require a repetitive replacement 

compliance time for the rail pressure control 

valve of within every 600 flight hours. The 

MCAIs instruct the operators to follow 

Thielert Maintenance Manual, Chapter 5, 

Airworthiness Limitations, for the repetitive 

compliance time. 

(3) We exclude the repetitive inspections of 

the alternator on TAE 125–01 engines, as we 

consider these inspections as maintenance 

actions. 

Alternative Methods of Compliance 

(AMOCs)

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) 

originated 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 the door 2 area, the hat-racks are 

supplied with a basic wire harness which 

includes ‘‘Oxygen Masks’’ activation. 

In case of a monument installation, the 

respective non-used hat-rack connections 

between monument and outer skin are put on 

stow. It was noticed in production, that the 

distance between the stowed wire harness 

and the monument could be too small. This 

condition, if not corrected, could lead to the 

short circuit of wires dedicated to oxygen, 

which, in case of emergency, could result in 

a large number of passenger oxygen masks 

not being supplied with oxygen, possibly 

causing personal injuries. 

* * * * * 

The proposed AD would require actions 

that are intended to address the unsafe 

condition described in the MCAI. 

DATES: We must receive comments on 

this proposed AD by December 3, 2009.
