AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (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) 

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: 

It was noticed on assembly line an 

elongation of bolts connecting power leads 

on R700 and R701 shunts. An incorrect 

tightening torque value is likely to be the 

cause of the elongation. 

This condition, if left uncorrected could 

lead to heating, electrical arcing or smokes 

and could result in an in-flight loss of 

electrical power. 

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 November 12, 

2009. 

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 No.: 

2009–0174, dated August 11, 2009 

(referred to after this as ‘‘the MCAI’’), to 

correct an unsafe condition for the 

specified products. The MCAI states: 

It was noticed on assembly line an 

elongation of bolts connecting power leads 

on R700 and R701 shunts. An incorrect 

tightening torque value is likely to be the 

cause of the elongation. 

This condition, if left uncorrected could 

lead to heating, electrical arcing or smokes 

and could result in an in-flight loss of 

electrical power. 

For the reason described above, this 

Airworthiness Directive (AD) mandates the 

replacement of the power lead bolts on R700 

and R701 shunts. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

SOCATA has issued SOCATA 

Mandatory Service Bulletin SB 70–169, 

dated May 2009. The actions described 

in this service information are intended 

to correct the unsafe condition 

identified in the MCAI. 

FAA’s Determination and Requirements 

of the Proposed AD 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with this State of 

Design Authority, 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 and determined the unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

Differences between this Proposed 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 might 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. 

We might also have proposed 

different actions in this AD from those 

in the MCAI in order to follow FAA 

policies. Any such differences are 

highlighted in a NOTE within the 

proposed AD. 

Costs of Compliance 

We estimate that this proposed AD 

will affect 47 products of U.S. registry. 

We also estimate that it would take 

about 0.5 work-hour per product to 

comply with the basic requirements of 

this proposed AD (warranty credit 

provided by manufacturer). The average 

labor rate is $80 per work-hour. 

Required parts would cost about $50 per 

product (warranty credit provided by 

manufacturer). Where the service 

information lists required parts costs 

that are covered under warranty, we 

have assumed that there will be no 

charge for these costs. As we do not 

control warranty coverage for affected 

parties, some parties may incur costs 

higher than estimated here. 

Based on these figures, we estimate 

the cost of the proposed AD on U.S. 

operators to be $4,230, or $90 per 

product. 

Authority for this Rulemaking 

Title 49 of the United States Code 

specifies the FAA’s authority to issue 


CPrice-Sewell on DSKGBLS3C1PROD with PROPOSALS
49346 Federal Register / Vol. 74, No. 186 / Monday, September 28, 2009 / Proposed Rules 

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: 

Socata: Docket No. FAA–2009–0886; 

Directorate Identifier 2009–CE–045–AD. 

Comments Due Date 

(a) We must receive comments by 

November 12, 2009. 

Affected ADs 

(b) None 

Applicability 

(c) This AD applies to TBM 700 airplanes, 

serial numbers 434 through 502, and serial 

numbers 504 and 505, certificated in any 

category. 

Subject 

(d) Air Transport Association of America 

(ATA) Code 24: Electric Power. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

It was noticed on assembly line an 

elongation of bolts connecting power leads 

on R700 and R701 shunts. An incorrect 

tightening torque value is likely to be the 

cause of the elongation. 

This condition, if left uncorrected could 

lead to heating, electrical arcing or smokes 

and could result in an in-flight loss of 

electrical power. 

For the reason described above, this 

Airworthiness Directive (AD) mandates the 

replacement of the power lead bolts on R700 

and R701 shunts. 

Actions and Compliance 

(f) Unless already done, within the next 

100 hours time-in-service after the effective 

date of this AD, or within the next 12 months 

after the effective date of this AD, whichever 

occurs first, replace the bolts of shunts R700 

and R701 following SOCATA Mandatory 

Service Bulletin SB 70–169, dated May, 2009. 

FAA AD Differences 

Note: This AD differs from the MCAI and/ 

or service information as follows: No 

differences. 

Other FAA AD Provisions 

(g) The following provisions also apply to 

this AD: 

(1) Alternative Methods of Compliance 

(AMOCs): The Manager, Standards Office, 

FAA, has the authority to approve AMOCs 

for this AD, if requested using the procedures 

found in 14 CFR 39.19. Send information to 

ATTN: Albert Mercado, Aerospace Engineer, 

FAA, Small Airplane Directorate, 901 Locust, 

Room 301, Kansas City, Missouri 64106;

any airplane to which the AMOC applies, 

notify your appropriate principal inspector 

(PI) in the FAA Flight Standards District 

Office (FSDO), or lacking a PI, your local 

FSDO. 

(2) Airworthy Product: For any requirement 

in this AD to obtain corrective actions from 

a manufacturer or other source, use these 

actions if they are FAA-approved. Corrective 

actions are considered FAA-approved if they 

are approved by the State of Design Authority 

(or their delegated agent). You are required 

to assure the product is airworthy before it 

is returned to service. 

(3) Reporting Requirements: For any 

reporting requirement in this AD, under the 

provisions of the Paperwork Reduction Act 

(44 U.S.C. 3501 et seq.), the Office of 

Management and Budget (OMB) has 

approved the information collection 

requirements and has assigned OMB Control 

Number 2120–0056.
