AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

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 a report of a master 

cylinder yoke failure. We are issuing 

this AD to require actions to correct the 

unsafe condition on these products. 

DATES: This AD becomes effective 

February 26, 2007. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of February 26, 2007. 

ADDRESSES: You may examine the AD 

docket on the Internet at http://

SUPPLEMENTARY INFORMATION

Streamlined Issuance of AD 

The FAA is implementing a new 

process for streamlining the issuance of 

ADs related to MCAI. The streamlined 

process will allow us to adopt MCAI 

safety requirements in a more efficient 

manner and will reduce safety risks to 

the public. This process continues to 

follow all FAA AD issuance processes to 

meet legal, economic, Administrative 

Procedure Act, and Federal Register 

requirements. We also continue to meet 

our technical decision-making 

responsibilities to identify and correct 

unsafe conditions on U.S.-certificated 

products. 

This AD references the MCAI and 

related service information that we 

considered in forming the engineering 

basis to correct the unsafe condition. 

The AD contains text copied from the 

MCAI and for this reason might not 

follow our plain language principles. 

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 November 28, 2006 (71 FR 

68762). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states that there 

was a report of a master cylinder yoke 

failure. The AD requirements are to 

detect defective yokes on aircraft and 

replace them. The aim of this AD is to 

ensure that normal braking is available 

at any time to prevent possible runway 

excursions in the event of failure of the 

master cylinder yoke. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

have considered the comments received. 

EADS SOCATA gave comments 

addressing the following: 

Comment Issue No. 1: Cost of 

Compliance 

EADS SOCATA states: 

The proposed AD specifies that: ‘‘Required 

parts would cost about $600’’. $600 

corresponds to the cost of the replacement of 

all (4) the master cylinder yokes. According 

to EADS Socata experience, operators 

complying with EADS Socata SB70–136–32 

had to replace only one yoke in the worst 

case. 

The FAA does not agree. We are using 

the worst case scenario of all four yokes 

being replaced. If an operator needs to 

replace fewer yokes, the cost will be 

less. 

Comment Issue No. 2: Applicability 

EADS SOCATA states: 

We propose to specify: ‘‘This AD applies 

to SOCATA Model TBM700 airplanes, all 

serial number, certificated in any category 

equipped with master cylinder assembly part 

number ZOO.N6068757280 or 

ZOO.N6068757281’’. 

Indeed, the supplier of the master cylinder 

assembly could change in the future and 

aircraft equipped with another part number 

would not be concerned. 

The FAA does not agree. Including 

the part number in the applicability is 

redundant. Per the AD, the operator has 

to verify whether the applicable part 

number is installed and, if so, take 

appropriate action. If a different part 

number from a different supplier is 

installed, then the AD does not apply. 

Comment Issue No. 3: Actions and 

Compliance, Paragraphs (e)(1)(ii)(B) and 

(e)(2) 

EADS SOCATA states: 

Paragraph (e)(1)(ii)(B): 

Yokes part number ZOO.N7134732200 

(delivered since January 2006) can also be 

installed on aircraft. Socata decides to 

produce itself yoke part number 

T700A324004810000 for logistic reasons but 

the design of this yokes is the same as Parker 

yoke part number ZOO.N7134732200. 

Paragraph (e)(2): 

During installation of master cylinder yoke 

part number ZOO.N7134732200 or 

installation of master cylinder assembly part 

number ZOO.N6068757280 or 

ZOO.N6068757281, we propose to check the 

yokes in accordance with SB70–136–32 only 

if these parts were delivered new before 

January 2006. 

The FAA does not agree. Since these 

parts are not serialized and tracked, 

there would be no way of knowing if the 

part was delivered before or after 

January 2006. In addition, EADS 

SOCATA TBM Aircraft Mandatory 

Service Bulletin SB 70–136, ATA No. 

32, dated December 2005, requires 

installation of yoke part number 

T700A324004810000. If an operator 

wants to use a different part numbered 

component and can show that it 

provides an acceptable level of safety, 

the operator can make a request to the 

FAA to approve an alternative method 

of compliance (AMOC) using the 

procedures in 14 CFR part 39 and this 

AD.

Federal Register / Vol. 72, No. 13 / Monday, January 22, 2007 / Rules and Regulations 2609 

Conclusion 

We reviewed the available data, 

including the comments received, 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 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 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, and take 

precedence over the actions copied from 

the MCAI. 

Costs of Compliance 

We estimate that this AD will affect 

270 products of U.S. registry. We also 

estimate that it will take about 1.5 workhours per product to comply with this 

AD. The average labor rate is $80 per 

work-hour. Required parts will cost 

about $600 per product. Where the 

service information lists required parts 

costs that are covered under warranty, 

we have assumed that there will be no 

charge for these parts. 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 

this AD to the U.S. operators to be 

$194,400 or $720 per product. 

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 

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. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http://dms.dot.gov; or in 

person at the Docket Management 

Facility between 9 a.m. and 5 p.m., 

Monday through Friday, except Federal 

holidays. The AD docket contains the 

NPRM, the regulatory evaluation, any 

comments received, and other 

information. The street address for the 

Docket Office (telephone (800) 647–

5227) is in the ADDRESSES section. 

Comments will be available in the AD 

docket shortly after receipt.

Adoption of the Amendment 

■ Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 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: 

2007–02–08 EADS SOCATA: Amendment 

39–14895; Docket No. FAA–2006–26232; 

Directorate Identifier 2006–CE–62–AD. 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective February 26, 2007. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to SOCATA Model 

TBM 700 airplanes, all serial numbers, 

certificated in any category. 

Reason 

(d) The mandatory continuing 

airworthiness information (MCAI) states 

there was a report of a master cylinder yoke 

failure. The AD requirements are to detect 

defective yokes on aircraft and replace them. 

The aim of this AD is to ensure that normal 

braking is available at any time to prevent 

possible runway excursions in the event of 

failure of the master cylinder yoke. 

Actions and Compliance 

(e) Unless already done, do the following 

actions. 

(1) For the serial numbers indicated below, 

within the next 100 hours time in service or 

12 months after the effective date of this AD, 

whichever occurs first: 

(i) For airplane serial numbers 269 and 339 

and up, check the aircraft records to 

determine whether the original cylinder yoke 

or yokes in the master cylinder assembly 

(both left-hand and right-hand) delivered 

with the airplane are installed. This check 

can be done by an owner/operator holding at 

least a private pilot certificate as authorized 

by section 43.7 of the Federal Aviation 

Regulations (14 CFR 43.7). 

(A) If you can positively identify that the 

original yokes in the master cylinder 

assemblies (both left-hand and right-hand) 

delivered with the airplane are installed, 

then make an entry in the aircraft records 

showing compliance with this AD per section 

43.9 of the Federal Aviation Regulations (14 

CFR 43.9). 

(B) If you cannot positively identify that 

the original yokes in the master cylinder 

assemblies (both left-hand and right-hand) 

delivered with the airplane are installed or if 

any of the master cylinder yokes have been 

replaced, then proceed to paragraph (e)(1)(ii) 

of this AD. 

(ii) For all airplane serial numbers, unless 

the action is shown not to apply per 

paragraph (e)(1)(i)(A) of this AD, inspect for 

misalignment of the master cylinder yokes 

from their threaded pins, as instructed in the 

EADS SOCATA TBM Aircraft Mandatory 

Service Bulletin SB 70–136, ATA No. 32, 

dated December 2005, accomplishment 

instructions paragraph. 

(A) If a yoke is found satisfactory, proceed 

to its re-installation on aircraft. 

(B) If a yoke is found defective, prior to 

further flight, discard the yoke and install a 

new part number T700A324004810000 (or 

FAA-approved equivalent part number) yoke 

in accordance with EADS SOCATA TBM 

Aircraft Mandatory Service Bulletin SB 70–

136, ATA No. 32, dated December 2005. 

(2) For all airplane serial numbers, as of the 

effective date of this AD, do not install part 

number ZOO.N7134732200 yokes or yokes in 


sroberts on PROD1PC70 with RULES
2610 Federal Register / Vol. 72, No. 13 / Monday, January 22, 2007 / Rules and Regulations 

master cylinder assembly part number 

ZOO.N6068757280 (left hand side) and 

ZOO.N6068757281 (right hand side), unless 

EADS SOCATA TBM Aircraft Mandatory 

Service Bulletin SB 70–136, ATA No. 32, 

dated December 2005, is complied with. 

FAA AD Differences 

Note: This AD differs from the MCAI and/ 

or service information as follows: 

(1) It does not allow interim use of yokes 

found defective during inspection. FAA 

policy is to replace defective parts on critical 

systems. 

(2) It applies to all serial numbers. This 

will assure that, if any of the airplanes had 

the affected part number yokes installed after 

delivery of the airplane, the unsafe condition 

is still addressed. It also will assure that any 

of the affected part number yokes are 

inspected per the AD and service bulletin 

before future installation of these parts. 

Other FAA AD Provisions 

(f) The following provisions also apply to 

this AD: 

(1) Alternative Methods of Compliance

329 4090, has the authority to approve 

AMOCs for this AD, if requested using the 

procedures found in 14 CFR 39.19. 

(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.

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for RollsRoyce Deutschland Ltd & Co KG (RRD) 

Dart 528, 529, 532, 535, 542, and 555 

series turboprop engines. This AD 

requires a dimensional inspection of the 

intermediate pressure turbine (IPT) disk 

or an ultrasonic inspection of the seal 

arm contact between the high pressure 

turbine (HPT) and the IPT disk seal arm 

and rework or replacement of the IPT 

disk if wear outside acceptable limits is 

found. This AD results from reports of 

a number of HPT disk failures, some of 

which resulted in portions of the HPT 

disk being released. We are issuing this 

AD to prevent HPT disk failure, which 

can result in an uncontained engine 

failure and damage to the airplane. 

DATES: This AD becomes effective 

February 26, 2007. The Director of the 

Federal Register approved the 

incorporation by reference of certain 

publications listed in the regulations as 

of February 26, 2007.

SUPPLEMENTARY INFORMATION: The FAA 

proposed to amend 14 CFR part 39 with 

a proposed AD. The proposed AD 

applies to RRD Dart 528, 529, 532, 535, 

542, and 555 series turboprop engines. 

We published the proposed AD in the 

Federal Register on July 11, 2006 (71 FR 

39023). That action proposed to require 

a dimensional inspection of the IPT disk 

or an ultrasonic inspection of the seal 

arm contact between the HPT and the 

IPT disk seal arm and rework or 

replacement of the IPT disk if wear 

outside acceptable limits is found. 

Examining the AD Docket 

You may examine the docket that 

contains the AD, any comments 

received, and any final disposition in 

person at the Docket Management 

Facility Docket Office between 9 a.m. 

and 5 p.m., Monday through Friday, 

except Federal holidays. The Docket 

Office (telephone (800) 647–5227) is 

located on the plaza level of the 

Department of Transportation Nassif 

Building at the street address stated in 

ADDRESSES. Comments will be available 

in the AD docket shortly after the DMS 

receives them. 

Comments 

We provided the public the 

opportunity to participate in the 

development of this AD. We have 

considered the comment received. 

Request To Incorporate by Reference 

and Publish the SBs 

One commenter, the Modification and 

Replacement Parts Association 

(MARPA), requests that we incorporate 

by reference (IBR) the SBs referenced in 

the proposed AD. We agree. This final 

rule AD IBRs the documents necessary 

for accomplishing the requirements 

mandated by this AD. We did not 

change the AD. 

MARPA also requests that we publish 

those SBs that we IBR, in Docket File 

FAA–2006–24825 of the Docket 

Management System (DMS). We are 

reviewing issues surrounding posting of 

service bulletins on the DMS as part of 

an AD docket. Once we have thoroughly 

examined all aspects of this issue and 

have made a final determination, we 

will consider whether our current 

practice needs to be revised. No change 

to the final rule is necessary in response 

to this comment.
