14644 Federal Register / Vol. 78, No. 45 / Thursday, March 7, 2013 / Rules and Regulations 

(d) Subject 

Air Transport Association (ATA) of 

America Code 24: Electrical Power. 

(e) Reason 

This AD was prompted by a report that 

certain ceramic terminal blocks, through 

which the wiring for the engine fire 

extinguishers, fire detection circuits, and 

engine and intake anti-ice system are routed, 

have been found to have moisture ingress, 

which can degrade the insulation resistance 

of the ceramic terminal blocks. We are 

issuing this AD to prevent latent failure of 

the number 2 fire bottle, which, in the event 

of an engine fire, could result in failure of the 

fire bottle to discharge when activated and 

possibly preventing the flightcrew from 

extinguishing an engine fire. 

(f) Compliance 

You are responsible for having the actions 

required by this AD performed within the 

compliance times specified, unless the 

actions have already been done. 

(g) Inspection 

Within 4,000 flight cycles or 18 months, 

whichever occurs first after the effective date 

of this AD, do an insulation resistance test on 

each terminal block, in accordance with 

paragraphs 2.C., 2.D., 2.E., and 2.F. of the 

Accomplishment Instructions of BAE 

SYSTEMS (OPERATIONS) LIMITED 

Inspection Service Bulletin 24–143, Revision 

1, dated October 2, 2012. 

(h) Replacement 

If, during the test required by paragraph (g) 

of this AD, any terminal block is found to 

have a value of less than 50 megohms, before 

next flight, replace it with a new or 

serviceable terminal block, in accordance 

with paragraph 2.G. of the Accomplishment 

Instructions of BAE SYSTEMS 

(OPERATIONS) LIMITED Inspection Service 

Bulletin 24–143, Revision 1, dated October 2, 

2012. 

(i) Inspection Report Difference 

Where BAE SYSTEMS (OPERATIONS) 

LIMITED Inspection Service Bulletin 24–143, 

Revision 1, dated October 2, 2012, specifies 

to complete the test result sheets in 

Appendices 1, 2, 3, and 4 and the inspection 

report in Appendix 6, and send the 

information to BAE SYSTEMS 

(OPERATIONS) LIMITED, this AD does not 

require that action. 

(j) Credit for Previous Actions 

This paragraph provides credit for actions 

required by paragraphs (g) and (h) of this AD, 

if those actions were performed before the 

effective date of this AD using BAE 

SYSTEMS (OPERATIONS) LIMITED 

Inspection Service Bulletin 24–143, dated 

September 26, 2011, which is not 

incorporated by reference in this AD.

Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

The Boeing Company Model 737–600, 

–700, –800, and –900ER series 

airplanes. This AD was prompted by 

incorrect wire support clamps installed 

within the left environmental control 

systems (ECS) bay, which could allow 

wiring to come in contact with the 

exposed metal of the improper clamp. 

This AD requires inspections to identify 

the part number of the wire support 

clamp, related investigative actions, and 

corrective actions if necessary. We are 

issuing this AD to prevent electrical 

arcing and a potential ignition source 

within the ECS bay, which in 

combination with flammable fuel 

vapors, could result in a center wing 

fuel tank explosion, and consequent loss 

of the airplane. 

DATES: This AD is effective April 11, 

2013. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of April 11, 2013.

SUPPLEMENTARY INFORMATION: 

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 published in the Federal 

Register on August 27, 2012 (77 FR 

51720). That NPRM proposed to require 

inspections to identify the part number 

(P/N) of the wire support clamp, related 

investigative actions, and corrective 

actions if necessary. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 

received on the proposal (77 FR 51720, 

August 27, 2012) and the FAA’s 

response to each comment. 

Statement To Address Effects of NPRM 

(77 FR 51720, August 27, 2012) on 

Winglets 

Aviation Partners Boeing stated that 

the installation of winglets per 

Supplemental Type Certificate (STC) 

ST00830SE (http://rgl.faa.gov/ 

Regulatory_and_Guidance_Library/

rgstc.nsf/0/408E012E008616A78625788

80060456C?OpenDocument&High

light=st00830se) does not affect the 

actions specified by the NPRM (77 FR 

51720, August 27, 2012). 

Requests To Remove or Change the 

‘‘Parts Installation Prohibition’’ Section 

Boeing requested the ‘‘Parts 

Installation Prohibition,’’ paragraph (h) 

of the NPRM (77 FR 51720, August 27, 

2012), be removed because there are 

other types of clamps installed within 

the ECS bay that are not included in 

either Boeing Special Attention Service 

Bulletin 737–28–1303, dated April 26, 

2012, or the NPRM (77 FR 51720, 

August 27, 2012). Boeing also requested 

that we include P/Ns TA0930034–10P, 

TA0930034–11, and TA0930034–12P 

wire support clamps because they are 

interchangeable with P/N TA0930034– 

10. Alaska Airlines requested that the 

‘‘Parts Installation Prohibition’’ 

paragraph be changed to clarify affected 

airplanes, and pointed out that AD 

2010–24–11, Amendment 39–16530 (75 

FR 74616, December 1, 2010), also 

addresses clamps installed in the left 

ECS bay, but allows installation of 

clamp P/N TA0930034–11 at the same 

clamp position. Delta Air Lines (Delta) 

requested that we ensure that paragraph 

(h) of the NPRM, only applies to those 

airplanes subject to the NPRM. Japan 

Airlines requested that we specify, in 

paragraph (h) of the NPRM, the 

locations within the left ECS bay that P/ 

N TA0930034–10P clamps may be 

installed. 

We agree to revise paragraph (i) of this 

AD (referred to as paragraph (h) in the 

NPRM (77 FR 51720, August 27, 2012)). 

We agree to allow installation of wire 

support clamps P/Ns TA0930034–10P, 

TA0930034–11, and TA0930034–12P, in 

addition to P/N TA0930034–10, and to 

limit the prohibition to the locations 

specified in Figures 1 through 4 of 

Boeing Special Attention Service 

Bulletin 737–28–1303, dated April 26, 

2012. We have revised paragraph (i) of 

this AD accordingly. 

In addition, we agree to clarify the 

phrase ‘‘on any airplane’’ used in 

paragraph (i) of this AD. The 

applicability statement in all AD actions 

lists all airplanes affected by that AD. 

All of the requirements stated in an AD 

are applicable only to the airplanes 

listed in the applicability of that AD. We 

have not changed the final rule 

regarding this issue. 

Requests To Allow Use of Certain Other 

Wire Support Clamps 

Boeing and Japan Airlines requested 

that the NPRM (77 FR 51720, August 27, 

2012) allow use of certain other wire 

support clamps in addition to P/N 

TA0930034–10, as specified by Boeing 

Special Attention Service Bulletin 737– 

28–1303, dated April 26, 2012. Japan 

Airlines requested that we allow the use 

of clamp P/N TA0930034–10P, and 

referred to discussions with Boeing that 

support use of this part number clamp, 

that is also fully cushioned. Boeing 

requested the corrective actions 

statement in the ‘‘Relevant Service 

Information’’ section of the preamble of 

the NPRM (77 FR 51720, August 27, 

2012) be revised to read, ‘‘Corrective 

actions include replacing the discrepant 

clamp with a new or serviceable 

TA0930034–10, TA0930034–10P, 

TA0930034–11, or TA0930034–12P 

wire support clamp if the part number 

is incorrect, and repairing or replacing 

chafed wiring.’’ Boeing stated that P/Ns 

TA0930034–10P, TA0930034–11, and 

TA0930034–12P are interchangeable 

with P/N TA0930034–10. 

We agree to allow installation of P/Ns 

TA0930034–10P, TA0930034–11, and 

TA0930034–12P wire support clamps. 

We have added new paragraph (h) in 

this final rule to provide an exception 

to Boeing Special Attention Service 

Bulletin 737–28–1303, dated April 26, 

2012, allow use of P/Ns TA0930034– 

10P, TA0930034–11, and TA0930034– 

12P wire support clamps. We have reidentified subsequent paragraphs 

accordingly. 

We partially agree with the intent of 

Boeing’s request to revise the ‘‘Relevant 

Service Information’’ section of the 

NPRM (77 FR 51720, August 27, 2012). 

Boeing’s request included removing the 

phrase ‘‘or if the flange cushions do not 

completely surround the two metal 

strap sections of the wire support 

clamp.’’ This phrase is based on the 

procedures specified in Step 1 of 

Figures 1 and 2 of Boeing Special 

Attention Service Bulletin 737–28– 

1303, dated April 26, 2012, and is part 

of the inspection required by this AD. 

Therefore, we do not agree that this 

phrase should be removed from the 

description of the inspection. As stated 

previously, we do agree that installing 

P/Ns TA0930034–10P, TA0930034–11, 

and TA0930034–12P wire support 

clamps is acceptable for accomplishing 

the corrective action. However, the 

‘‘Relevant Service Information’’ section 

of the NPRM is not restated in this AD, 

so we have not revised this AD in this 

regard.

14646 Federal Register / Vol. 78, No. 45 / Thursday, March 7, 2013 / Rules and Regulations 

Request To Clarify Impacted Fuel Tank 

Boeing requested that the ‘‘Summary’’ 

and ‘‘Discussion’’ sections in the NPRM 

(77 FR 51720, August 27, 2012) be 

revised to add the text, ‘‘in the center 

wing tank,’’ and to read, ‘‘We are 

proposing this AD to prevent electrical 

arcing and a potential ignition source in 

the center wing tank, which in 

combination with flammable fuel vapors 

could result in a fuel tank explosion, 

and consequent loss of the airplane,’’ to 

clarify the area that might be potentially 

impacted by the unsafe condition 

identified in the NPRM. 

We partially agree. We agree with 

Boeing’s request to identify the center 

wing tank as the impacted tank, because 

the center wing tank located above the 

ECS bay is the fuel tank potentially 

affected by the unsafe condition 

identified in this AD. We disagree to 

state that this AD will prevent electrical 

arcing and a potential ignition source in 

the center wing tank, because the 

potential ignition source has been 

identified to be within the ECS bay, 

which is a flammable leakage fluid 

zone. A potential ignition within the 

ECS bay could lead to a fire in the area 

and potentially result in a center wing 

tank explosion. Therefore, we agree to 

identify the center wing tank as the 

affected fuel tank without including the 

misleading statement that this AD will 

prevent electrical arcing within the fuel 

tank. We further recognize that the same 

issue applies to paragraph (e), ‘‘Unsafe 

Condition,’’ of this AD and note that the 

‘‘Discussion’’ section that appeared in 

the NPRM (77 FR 51720, August 27, 

2012) is not restated in the final rule. 

We have revised the Summary and 

paragraph (e) of this AD to specify that 

we are issuing this AD ‘‘to prevent 

electrical arcing and a potential ignition 

source within the ECS bay, which in 

combination with flammable fuel 

vapors, could result in a center wing 

fuel tank explosion, and consequent loss 

of the airplane.’’ 

Request To Clarify Airplane 

Maintenance Data 

Delta pointed to inconsistencies 

between the type design data and the 

aircraft illustrated parts catalog (AIPC) 

used for maintaining airplanes. Delta 

stated that the AIPC does not accurately 

identify all clamp locations that are 

needed for AD compliance, and pointed 

out that discrepancies within type 

design data and maintenance data could 

result in a re-occurrence of clamp 

installation discrepancies, which 

occurred in production and resulted in 

the airworthiness directive. 

We acknowledge that if operators 

refer to and use an inaccurate AIPC, it 

could result in non-compliance with AD 

requirements. However, it is the 

responsibility of the operators to ensure 

that they are in compliance with AD 

requirements. In addition, the AIPC is 

not an FAA approved or controlled 

document. We have not changed the AD 

in this regard. 

Conclusion 

We reviewed the relevant data, 

considered the comments received, and 

determined that air safety and the 

public interest require adopting the AD 

with the changes described previously— 

and minor editorial changes. We have 

determined that these minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (77 FR 

51720, August 27, 2012) for correcting 

the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (77 FR 51720, 

August 27, 2012). 

We also determined that these 

changes will not increase the economic 

burden on any operator or increase the 

scope of the AD. 

Costs of Compliance 

We estimate that this AD affects 297 

airplanes of U.S. registry. 

We estimate the following costs to 

comply with this AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Number of 

airplanes 

Cost on U.S. 

operators 

Inspection Group 1 airplanes ............ 10 work-hours × $85 per hour = 

$850.

$0 $850 185 $157,250 

Inspection Group 2 airplanes ............ 2 work-hours × $85 per hour = $170 0 170 112 19,040 

We estimate the following costs to do 

any necessary replacements that would 

be required based on the results of the 

required inspection. We have no way of 

determining the number of aircraft that 

might need these replacements. 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per 

product 

Replacement of wire support clamp ............................. 1 work-hour × $85 per hour = $85 ............................... $3 $88 

According to the manufacturer, some 

of the costs of this AD may be covered 

under warranty, thereby reducing the 

cost impact on affected individuals. We 

do not control warranty coverage for 

affected individuals. As a result, we 

have included all costs in our cost 

estimate. 

We have received no definitive data 

that would enable us to provide cost 

estimates for the on-condition repair of 

chafed or damaged wiring specified in 

this AD. 

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 


emcdonald on DSK67QTVN1PROD with RULES
Federal Register / Vol. 78, No. 45 / Thursday, March 7, 2013 / Rules and Regulations 14647 

that is likely to exist or develop on 

products identified in this rulemaking 

action. 

Regulatory Findings 

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 that 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), 

(3) Will not affect intrastate aviation 

in Alaska, and 

(4) 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.
