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.

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) 

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: 

Bombardier Aerospace has completed a 

system safety review of the CL–600–2C10/ 

CL600–2D15/CL–600–2D24 aircraft fuel 

system against the new fuel tank safety 

standards, introduced in Chapter 525 of the 

Airworthiness Manual through Notice of 

Proposed Amendment (NPA) 2002–043. The 

identified non-compliances were assessed 

using Transport Canada Policy Letter No. 

525–001 to determine if mandatory corrective 

action was required. 

The assessment showed that certain 

hydraulic system failure scenarios could lead 


CPrice-Sewell on DSKGBLS3C1PROD with PROPOSALS
Federal Register / Vol. 74, No. 186 / Monday, September 28, 2009 / Proposed Rules 49347 

to a rapid overheat in the hydraulic lines 

without giving flight crew sufficient time to 

react before the No. 1 and No. 2 hydraulic 

system tubing inside the fuel tank reaches the 

fuel auto ignition temperature. This could 

result in a fuel tank explosion. 

* * * * * 

The proposed AD would require actions 

that are intended to address the unsafe 

condition described in the MCAI.

Discussion 

Transport Canada Civil Aviation, 

which is the aviation authority for 

Canada, has issued Canadian 

Airworthiness Directive CF–2009–09, 

dated March 9, 2009 (referred to after 

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

condition for the specified products. 

The MCAI states: 

Bombardier Aerospace has completed a 

system safety review of the CL–600–2C10/ 

CL600–2D15/CL–600–2D24 aircraft fuel 

system against the new fuel tank safety 

standards, introduced in Chapter 525 of the 

Airworthiness Manual through Notice of 

Proposed Amendment (NPA) 2002–043. The 

identified non-compliances were assessed 

using Transport Canada Policy Letter No. 

525–001 to determine if mandatory corrective 

action was required. 

The assessment showed that certain 

hydraulic system failure scenarios could lead 

to a rapid overheat in the hydraulic lines 

without giving flight crew sufficient time to 

react before the No. 1 and No. 2 hydraulic 

system tubing inside the fuel tank reaches the 

fuel auto ignition temperature. This could 

result in a fuel tank explosion. 

To correct the unsafe condition, this 

[Canadian airworthiness] directive mandates 

the installation of thermal fuses in the No. 1 

and No. 2 hydraulic systems and the 

introduction of Fuel System Limitations 

(FSL) and Critical Design Configuration 

Control Limitations (CDCCL) associated with 

this design change. 

You may obtain further information 

by examining the MCAI in the AD 

docket. 

The FAA has examined the 

underlying safety issues involved in fuel 

tank explosions on several large 

transport airplanes, including the 

adequacy of existing regulations, the 

service history of airplanes subject to 

those regulations, and existing 

maintenance practices for fuel tank 

systems. As a result of those findings, 

we issued a regulation titled ‘‘Transport 

Airplane Fuel Tank System Design 

Review, Flammability Reduction and 

Maintenance and Inspection 

Requirements’’ (66 FR 23086, May 7, 

2001). In addition to new airworthiness 

standards for transport airplanes and 

new maintenance requirements, this 

rule included Special Federal Aviation 

Regulation No. 88 (‘‘SFAR 88,’’ 

Amendment 21–78, and subsequent 

Amendments 21–82 and 21–83). 

Among other actions, SFAR 88 

requires certain type design (i.e., type 

certificate (TC) and supplemental type 

certificate (STC)) holders to substantiate 

that their fuel tank systems can prevent 

ignition sources in the fuel tanks. This 

requirement applies to type design 

holders for large turbine-powered 

transport airplanes and for subsequent 

modifications to those airplanes. It 

requires them to perform design reviews 

and to develop design changes and 

maintenance procedures if their designs 

do not meet the new fuel tank safety 

standards. As explained in the preamble 

to the rule, we intended to adopt 

airworthiness directives to mandate any 

changes found necessary to address 

unsafe conditions identified as a result 

of these reviews. 

In evaluating these design reviews, we 

have established four criteria intended 

to define the unsafe conditions 

associated with fuel tank systems that 

require corrective actions. The 

percentage of operating time during 

which fuel tanks are exposed to 

flammable conditions is one of these 

criteria. The other three criteria address 

the failure types under evaluation: 

single failures, single failures in 

combination with a latent condition(s), 

and in-service failure experience. For all 

four criteria, the evaluations included 

consideration of previous actions taken 

that may mitigate the need for further 

action. 

Relevant Service Information 

Bombardier has issued Service 

Bulletin 670BA–29–005, Revision A, 

dated January 29, 2009; Bombardier 

Temporary Revision 2–268, dated 

December 18, 2008, to Section 3, ‘‘Fuel 

System Limitations,’’ of Part 2 of the 


CPrice-Sewell on DSKGBLS3C1PROD with PROPOSALS
49348 Federal Register / Vol. 74, No. 186 / Monday, September 28, 2009 / Proposed Rules 

Bombardier CL–600–2C10, CL–600– 

2D15, and CL–600–2D24 Maintenance 

Requirements Manual; and Bombardier 

Temporary Revision 2–269, dated 

December 18, 2008, to Section 3, ‘‘Fuel 

System Limitations,’’ of Part 2 of the 

Bombardier CL–600–2C10, CL–600– 

2D15, and CL–600–2D24 Maintenance 

Requirements Manual. 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 another 

country, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with the State of 

Design Authority, we have been notified 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all pertinent 

information and determined an unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

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 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 

Based on the service information, we 

estimate that this proposed AD would 

affect about 334 products of U.S. 

registry. We also estimate that it would 

take about 45 work-hours per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $80 per work-hour. Required 

parts would cost about $6,765 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 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 

$3,461,910, or $10,365 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 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.

Identifier 2009–NM–057–AD. 

Comments Due Date 

(a) We must receive comments by 

November 12, 2009. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to Bombardier Model 

CL–600–2C10 (Regional Jet Series 700, 701, 

& 702), airplanes; certificated in any category, 

having serial numbers 10003 through 10267 

inclusive; and Bombardier Model CL–600–

any category, having serial numbers 15001 

through 15199 inclusive, 15202, and 15204. 

Note 1: This AD requires revisions to 

certain operator maintenance documents to 

include new inspections. Compliance with 

these inspections is required by 14 CFR 

91.403(c). For airplanes that have been 

previously modified, altered, or repaired in 

the areas addressed by these inspections, the 

operator may not be able to accomplish the 

inspections described in the revisions. In this 

situation, to comply with 14 CFR 91.403(c), 

the operator must request approval for an 

alternative method of compliance according 

to paragraph (g) of this AD. The request 

should include a description of changes to 

the required inspections that will ensure the 

continued operational safety of the airplane.

of the maintenance program, the general 

revision may be inserted into the 

maintenance requirements manual, provided 

the relevant information in the general 

revision is identical to that in the TR, and the 

temporary revision may be removed. 

(4) After accomplishing the actions 

specified in paragraphs (f)(2) and (f)(3) of this 

AD, no alternative limitation tasks, limitation 

task intervals, or CDCCLs may be used unless 

the limitation task, limitation task interval, or 

CDCCL is approved as an alternative method 

of compliance (AMOC) in accordance with 

the procedures specified in paragraph (g)(1) 

of this AD. 

(5) Actions accomplished before the 

effective date of this AD in accordance with 

Bombardier Service Bulletin 670BA–29–005,

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) 

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: 

Several cases have been reported where a 

passenger door actuator detached from the 

passenger door. This caused the passenger 

door to drop to the platform in an 

uncontrolled manner. 

This condition, if not corrected, could 

result in injury to persons on the ground and 

damage to the aircraft. 

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 October 28, 2009. 

ADDRESSES: You may send comments by 

any of the following methods: 

• Federal eRulemaking Portal: Go to 

http://www.regulations.gov. Follow the 

instructions for submitting comments. 

• Fax: (202) 493–2251.
