(e) Unsafe Condition 

This AD was prompted by a review of the 

tail strobe light installation, which revealed 

that the tail strobe light is not electrically 

bonded to primary structure of the airplane. 

We are issuing this AD to prevent, in case of 

a direct lightning strike to the tail strobe 

light, damage to the operation of other 

critical airplane systems due to 

electromagnetic coupling and large transient 

voltages, and damage to the control 

mechanisms or surfaces due to a fire, which 

could result in loss of control of the airplane. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done.

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, –700C, –800, –900, and –900ER 

series airplanes. This AD was prompted 

by a report of installation of incorrect 

wire support clamps within the bay area 

of the left and right environmental 

control systems (ECS) during 

production; the ECS bay area is a 

flammable fluid leakage zone. Use of 

incorrect wire support clamps that are 

not fully cushioned could allow 

electrical power wiring to come in 

contact with the exposed metal of the 

improper clamp, causing a short circuit 


wreier-aviles on DSK5TPTVN1PROD with RULES
Federal Register / Vol. 79, No. 135 / Tuesday, July 15, 2014 / Rules and Regulations 41091 

and subsequent electrical arcing. This 

AD requires inspecting to identify the 

part number of the wire support clamp, 

and related investigative and corrective 

actions if necessary. We are issuing this 

AD to prevent electrical arcing and a 

potential ignition source, which, in 

combination with flammable fuel 

vapors, could result in a fuel tank 

explosion, and consequent loss of the 

airplane. 

DATES: This AD is effective August 19, 

2014.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to certain The Boeing Company 

Model 737–600, –700, –700C, –800, 

–900, and –900ER series airplanes. The 

NPRM published in the Federal 

Register on December 12, 2013 (78 FR 

75512). The NPRM was prompted by a 

report of installation of incorrect wire 

support clamps within the bay area of 

the left and right ECS during 

production; the ECS bay area is a 

flammable leakage zone. Use of 

incorrect wire support clamps that are 

not fully cushioned could allow 

electrical power wiring to come in 

contact with the exposed metal of the 

improper clamp, causing a short circuit 

and subsequent electrical arcing. The 

NPRM proposed to require inspecting to 

identify the part number of the wire 

support clamp, and related investigative 

and corrective actions if necessary. We 

are issuing this AD to prevent electrical 

arcing and a potential ignition source, 

which, in combination with flammable 

fuel vapors, could result in a fuel tank 

explosion, and consequent loss of the 

airplane. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 

received on the proposal (78 FR 75512, 

December 12, 2013) and the FAA’s 

response to each comment. 

Requests To Remove Certain Language 

in ‘‘Relevant Service Information’’ 

Section 

Boeing, All Nippon Airways (ANA), 

and American Airlines (AA) asked that 

the third sentence in the ‘‘Relevant 

Service Information’’ section of the 

NPRM (78 FR 75512, December 12, 

2013) be removed. That sentence 

specified ‘‘The related investigative 

actions include an eddy current 

inspection of the wing front spar for 

cracking and a detailed inspection of the 

bolt forward of the wing front spar 

upper chord for cracking or missing 

bolts.’’ Boeing stated that those actions 

seem unrelated to the intent of the AD. 

ANA stated that the eddy current 

inspection is not specified in Boeing 

Special Attention Service Bulletin 737– 

28–1312, dated April 19, 2013. AA 

stated that those actions are not 

included in the referenced service 

information, and asked that those 

actions be clarified or that the ‘‘Relevant 

Service Information’’ section be 

corrected by removing those actions. 

We agree that the ‘‘Relevant Service 

Information’’ section in the NPRM (78 

FR 75512, December 12, 2013) should 

not have stated that the related 

investigative actions include an eddy 

current inspection of the wing front spar 

for cracking; that inspection is not 

related to the unsafe condition 

addressed by this AD. However, the 

‘‘Relevant Service Information’’ section 

of the NPRM is not carried over into this 

final rule; therefore, no change to this 

final rule is necessary in this regard. 

Request To Include Equivalent Parts 

AA asked that we add ‘‘equivalent 

fully cushioned wire clamps’’ to the 

approved part numbers (P/Ns) identified 

in paragraph (h) of the proposed AD (78 

FR 75512, December 12, 2013) 

(redesignated as paragraph (i) of this 

AD). AA stated that paragraph (h) of the 

proposed AD prohibits the installation 

of a wire support clamp within the ECS 

bay area, unless the clamp has P/N 

TA0930034–10, TA0930034–10P, 

TA0930034–11, or TA0930034–12P. AA 

noted that adding ‘‘equivalent fully 

cushioned wire clamps’’ would account 

for future part number changes and 

future availability issues of the included 

part numbers. AA also asserted that 

including the equivalent clamps also 

would reduce the potential for airplanes 

becoming noncompliant during future 

maintenance. 

We do not agree to add ‘‘equivalent 

fully cushioned wire clamps’’ to the 

approved part numbers identified in 

paragraph (i) of this AD (designated as 

paragraph (h) of the proposed AD). AA 

did not submit any data to show how 

equivalency of the wire support clamp 

is to be established, maintained, and 

controlled. However, under the 

provisions of paragraph (j) of this AD, 

we may consider requests to use 

alternate clamps if sufficient data are 

submitted to substantiate that these 

clamps meet the standards for the 

environmental (temperature, vibration, 

fluid resistance) and performance 

requirements necessary to provide an 

acceptable level of safety. We have not 

changed this final rule in this regard. 

Request To Change Costs of Compliance 

Section 

AA asked that we change the 

inspection estimate in the ‘‘Costs of 

Compliance’’ section in the NPRM (78 

FR 75512, December 12, 2013) from 6 to 

24 work-hours, as specified in Boeing 

Special Attention Service Bulletin 737– 

28–1312, dated April 19, 2013. 

We agree to change the work-hour 

estimate for the inspection specified in 

the ‘‘Costs of Compliance’’ section. After 

further review of Boeing Special 

Attention Service Bulletin 737–28– 

1312, dated April 19, 2013, we have 

determined that the work-hour estimate 

of 24 hours is based on correct 

installation of the wire clamps and does 

not include repairs to the wiring. 

Therefore, we have increased the work 

hour estimate for the inspection 


wreier-aviles on DSK5TPTVN1PROD with RULES
41092 Federal Register / Vol. 79, No. 135 / Tuesday, July 15, 2014 / Rules and Regulations 

specified in the ‘‘Costs of Compliance’’ 

section of this final rule. 

Changes to This Final Rule 

Since we issued the NPRM (78 FR 

75512, December 12, 2013), Boeing has 

issued Special Attention Service 

Bulletin 737–28–1312, Revision 1, dated 

April 21, 2014. No additional work is 

necessary on airplanes that were 

changed using Boeing Special Attention 

Service Bulletin 737–28–1312, dated 

April 19, 2013. We have added Boeing 

Special Attention Service Bulletin 737– 

28–1312, Revision 1, dated April 21, 

2014, to paragraphs (c) and (g) of this 

AD, and added a new credit paragraph 

(h) to this AD giving credit for Boeing 

Special Attention Service Bulletin 737– 

28–1312, dated April 19, 2013. 

Since we issued the NPRM (78 FR 

75512, December 12, 2013), we have 

determined that the language used in 

the ‘‘Parts Installation Limitations’’ 

paragraph of the AD needs clarification. 

As written, the language could be 

interpreted as applying to ‘‘all’’ clamps 

located in the ECS bay area; however, 

the limitation only applies to certain 

clamps. We have changed paragraph (h) 

of the the proposed AD (redesignated as 

paragraph (i) of this AD) to provide that 

clarification. 

Conclusion 

We reviewed the relevant data, 

considered the comments received, and 

determined that air safety and the 

public interest require adopting this AD 

with the changes described previously. 

We also determined that these changes 

will not increase the economic burden 

on any operator or increase the scope of 

this AD. 

Costs of Compliance 

We estimate that this AD affects 519 

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 

Cost on U.S. 

operators 

Inspection ................................ 24 work-hours × $85 per hour = $2,040 ................................ $0 $2,040 $1,058,760 

We estimate the following costs to do 

any necessary related investigative and 

corrective actions that would be 

required based on the results of the 

inspection. We have no way of 

determining the number of aircraft that 

might need these actions. 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per 

product 

Related investigative and corrective 

actions.

1 work-hour × $85 per hour = $85 ............................................................ $3 $88 

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. 

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. 

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 

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 

the 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.

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 all The 

Boeing Company Model 707 airplanes, 

and Model 720 and 720B series 

airplanes. This AD was prompted by 

reports of scribe-line-related fatigue 

cracks on Model 727 airplanes, which 

are similar in design to Model 707 

airplanes, and Model 720 and 720B 

series airplanes. This AD requires 

inspections for scribe lines in the skin 

lap joints, external approved repairs, 

external features, skin butt joints, and 

decals; and related investigative and 

corrective actions if necessary. This AD 

also requires surface finish restoration. 

We are issuing this AD to detect and 

correct scribe lines, which can develop 

into fatigue cracks in the skin and cause 

rapid decompression of the airplane. 

DATES: This AD is effective August 19, 

2014. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of August 19, 2014.
