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 777–200 

series airplanes. This AD was prompted 

by reports of smoke or flames in the 

passenger cabin of various transport 

category airplanes related to the wiring 

for the passenger cabin in-flight 

entertainment (IFE) system, cabin 

lighting, and passenger seats. This AD 

requires, for certain airplanes, doing an 

inspection of the electrical power 

control panel for a certain part number, 

and corrective action if necessary; and, 

for certain other airplanes, installing a 

new electrical power control panel, and 

making changes to the wiring and 

certain electrical load management 

system (ELMS) panels. We are issuing 

this AD to ensure that the flightcrew is 

able to turn off electrical power to the 

IFE systems and other non-essential 

electrical systems through one or two 

switches in the flight deck in the event 

of smoke or flames. In the event of 

smoke or flames in the airplane flight 

deck or passenger cabin, the flightcrew’s 

inability to turn off electrical power to 

the IFE system and other non-essential 

electrical systems could result in the 

inability to control smoke or flames in 

the airplane flight deck or passenger 

cabin during a non-normal or 

emergency situation, and consequent 

loss of control of the airplane. 

DATES: This AD is effective September 

23, 2014. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of September 23, 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 777–200 series airplanes. The 

NPRM published in the Federal 

Register on July 17, 2013 (78 FR 42727). 

The NPRM was prompted by reports of 

smoke or flames in the passenger cabin 

of various transport category airplanes, 

related to the wiring for the passenger 

cabin IFE system, cabin lighting, and 

passenger seats. The NPRM proposed to 

require, for certain airplanes, doing an 

inspection of the electrical power 

control panel for a certain part number, 

and corrective action if necessary; and, 

for certain other airplanes, installing a 

new electrical power control panel, and 

making changes to the wiring and 

certain ELMS panels. We are issuing 

this AD to ensure that the flightcrew is 

able to turn off electrical power to the 

IFE systems and other non-essential 

electrical systems through one or two 

switches in the flight deck in the event 

of smoke or flames. In the event of 

smoke or flames in the airplane flight 

deck or passenger cabin, the flightcrew’s 

inability to turn off electrical power to 

the IFE system and other non-essential 

electrical systems could result in the 

inability to control smoke or flames in 

the airplane flight deck or passenger 

cabin during a non-normal or 

emergency situation, and consequent 

loss of control 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 42727, 

July 17, 2013) and the FAA’s response 

to each comment. 

Support for the NPRM (78 FR 42727, 

July 17, 2013) 

United Airlines (UA) supported the 

NPRM (78 FR 42727, July 17, 2013). 

Request To Accept Modification 

Deviations Proposed by Japan Airlines 

(JAL) 

Japan Airlines (JAL) requested that we 

accept modification deviations 

proposed by JAL. JAL stated that there 

were problems with the repair kits 

including short electrical wire and 

missing wires. JAL proposed various 

deviations from the service bulletin 

instructions in order to address these 

problems. 

We disagree with the request to accept 

modification deviations. The issues that 

JAL experienced with the Boeing kit 

may not be applicable to other 

operators; therefore, we are not 

changing this final rule in this regard. 

Operators may, however, request 

approval of an alternative method of 

compliance (AMOC) for deviations for 

the Boeing repair kit in accordance with 

paragraph (k) of this AD.

48966 Federal Register / Vol. 79, No. 160 / Tuesday, August 19, 2014 / Rules and Regulations 

Request To Use Alternative Service 

Information 

JAL requested that we allow the use 

of Boeing Service Bulletin 777–23–0254 

to load an alternative version of cabin 

management system (CMS) software. 

JAL stated that the NPRM (78 FR 42727, 

July 17, 2013), would require loading 

the CMS software in accordance with 

Boeing Service Bulletin 777–23–0176, 

Revision 2, dated October 26, 2006, as 

a concurrent requirement to Boeing 

Service Bulletin 777–23–0254. JAL 

stated that it has loaded this required 

software, but also loaded another 

version of the software for a cabin 

configuration change using Boeing 

Service Bulletin 777–23–0254. JAL 

stated that Boeing Service Bulletin 777– 

23–0254 identifies Boeing Service 

Bulletin 777–23–0176, Revision 2, dated 

October 26, 2006, as a concurrent 

requirement; JAL therefore requested 

that we include Boeing Service Bulletin 

777–23–0254 in the NPRM. 

We disagree with the request to use 

Boeing Service Bulletin 777–23–0254 to 

load an alternative version of CMS 

software. Although Boeing Service 

Bulletin 777–23–0254 identifies Boeing 

Service Bulletin 777–23–0176, Revision 

2, dated October 26, 2006, as a 

concurrent requirement, we have not 

evaluated the alternative software to 

ensure it provides an acceptable level of 

safety to the AD requirements. 

Operators may request approval of an 

AMOC for installation of this alternative 

CMS software in accordance with 

paragraph (k) of this AD. 

Request To Add New Optional Action 

Boeing and JAL requested that we 

revise the Costs of Compliance section 

and paragraph (i)(2) of the NPRM (78 FR 

42727, July 17, 2013) to add Boeing 

Service Bulletin 777–28A0039, Revision 

2, dated September 20, 2010, as an 

option to Boeing Service Bulletin 777– 

24–0077, Revision 4, dated October 17, 

2012, for installation of additional 

ELMS software. 

The commenters stated that the new 

ELMS software is required for 

compliance to another AD (AD 2011– 

09–15, Amendment 39–16677 (76 FR 

24345, May 2, 2011)). The commenters 

stated that AD 2011–09–15 requires 

installing new panels in the main 

equipment center and installing new 

ELMS software in accordance with 

Boeing Service Bulletin 777–28A0037, 

Revision 2, dated September 20, 2010, 

in order to prevent potential ignition 

sources inside fuel tanks. The 

commenters also stated that AD 2011– 

09–15 identifies Boeing Service Bulletin 

777–28A0039, Revision 2, dated 

September 20, 2010, as an additional 

source of guidance for installing ELMS 

software. 

Boeing and JAL stated that requiring 

ELMS software to be installed according 

to Boeing Service Bulletin 777–24–0087, 

Revision 2, dated August 16, 2007, as 

proposed in the NPRM (78 FR 42727, 

July 17, 2013), will create a conflict with 

the requirements of AD 2011–09–15, 

Amendment 39–16677 (76 FR 24345, 

May 2, 2011). Boeing stated that it 

intends to revise Service Bulletin 777– 

24–0077 to Revision 5 to include Boeing 

Service Bulletin 777–28A0039, Revision 

2, dated September 20, 2010, as 

concurrent service information. 

We agree to add an option to use 

Boeing Service Bulletin 777–28A0039, 

Revision 2, dated September 20, 2010, 

for installation of additional ELMS 

software. We have added this reference 

to the Costs of Compliance section and 

to paragraph (i)(2) of this final rule, as 

requested. 

Change to Final Rule 

For editorial purposes, we have 

moved the credit service bulletin 

references from paragraph (j)(3) of the 

NPRM (78 FR 42727, July 17, 2013) to 

new paragraphs (j)(3)(i) through (j)(3)(v) 

of this final rule. 

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 

and minor editorial changes. We have 

determined that these minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (78 FR 

42727, July 17, 2013) for correcting the 

unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (78 FR 42727, 

July 17, 2013). 

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 49 

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/installation and changes ............... Up to 28 work-hours × $85 per hour = 

$2,380.

$1,436 Up to $3,816 ..... Up to $186,984. 

Concurrent installation (Boeing Service Bulletin 777–23–0176, Revision 2, dated October 26, 2006).2 work-hours × $85 per hour = $170 ............ 0 $170 ................. $8,330. 

Concurrent installation (Boeing Service Bulletin 777–24–0077, Revision 4, dated October 17, 2012; Boeing Service Bulletin 

777–24–0087, Revision 2, dated August 

16, 2007; or Boeing Service Bulletin 777– 

28A0039, Revision 2, dated September 

20, 2010).

3 work-hours × $85 per hour = $255 ............ 0 $255 ................. $12,495. 

We estimate the following costs to do 

any necessary change that would be 

required based on the results of the 

inspection. We have no way of 

determining the number of aircraft that 

might need this replacement:

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 

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.

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are superseding 

Airworthiness Directive (AD) 2011–15– 

09 for certain Bombardier, Inc. Model 

DHC–8–400, –401, and –402 airplanes. 

AD 2011–15–09 required repetitive 

inspections for proper operation of the 

main landing gear (MLG) alternate 

extension system (AES), and corrective 

actions if necessary. This new AD 

requires, for certain airplanes, new 

repetitive inspections for proper 

operation of the MLG AES, and 

corrective actions if necessary. This new 

AD also requires eventually replacing 

the MLG AES cam mechanism assembly 

with a new assembly, which terminates 

the repetitive inspections for those 

airplanes. This AD was prompted by a 

determination that, for certain airplanes 

not affected by AD 2011–15–09, a 

different MLG AES cam mechanism 

assembly was installed, resulting in 

input lever fractures and inability to 

open the MLG door; those assemblies 

could be subject to the same unsafe 

condition in AD 2011–15–09. We are 

issuing this AD to prevent improper 

operation of the cam mechanism or 

rupture of the door release cable, which
