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, and 

–900 series airplanes. The NPRM 

published in the Federal Register on 

March 3, 2014 (79 FR 11728). The 

NPRM was prompted by reports in 

which a single, undetected, erroneous 

radio altimeter output caused the 

autothrottle to enter landing flare retard 

mode prematurely on approach. The 

NPRM proposed to require removing 

certain autothrottle computers and 

installing a new or reworked 

autothrottle computer. We are issuing 

this AD to prevent a single, undetected, 

erroneous radio altimeter output from 

causing premature autothrottle landing 

flare retard and subsequent loss of 

automatic speed control, which could 

result in 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 NPRM (79 FR 11728, 

March 3, 2014) and the FAA’s response 

to each comment. 

Support for the NPRM (79 FR 11728, 

March 3, 2014) 

Boeing and the National 

Transportation Safety Board (NTSB) 

concurred with the NPRM (79 FR 11728, 

March 3, 2014). 

Clarification of Effect of Winglet 

Installation 

Aviation Partners Boeing stated that 

installation of winglets per 

Supplemental Type Certificate (STC) 

ST00830SE does not affect the 

accomplishment of the manufacturer’s 

service instructions specified in the 

NPRM (79 FR 11728, March 3, 2014). 

Request To Change Cost Estimate 

Kevin Lee, a private citizen, requested 

that we increase the cost estimate of the 

NPRM (79 FR 11728, March 3, 2014). 

The commenter stated that the cost will 

be significantly higher due to General 

Electric not providing a free-of-charge 

upgrade to the autothrottle computer 

despite this being a safety and reliability 

issue. 

We disagree with increasing the cost 

estimate. The cost estimate does not 

include parts cost for the autothrottle 

computer because it is considered 

‘‘Parts and Materials Supplied by the 

Operator’’ in Boeing Alert Service 

Bulletin 737–22A1215, dated November 

22, 2013. The autothrottle computer 

software can be updated using a data 

loader on a bench with specific 

equipment that is unique to the GE 

autothrottle computer. However, since 

this autothrottle computer has been out 

of production for over ten years, it is 

unlikely that operators will have the 

capability to do the update themselves 

using a disc supplied by GE. Therefore, 

GE anticipates that the majority of 

operators will return their autothrottle 

computer to a GE service center for 

modification. As an alternative, 

operators may purchase the autothrottle 

computer from Boeing. Boeing Alert 

Service Bulletin 737–22A1215, dated 

November 22, 2013, does not give the 

cost and it is therefore not included in 

our estimate. Since there are multiple 

ways for operators to get an updated 

autothrottle computer, we have not 

included the cost of the autothrottle 

computer in our estimate. We also do 

not control warranty coverage. No 

change has been made to this final rule 

in this regard. 

Request To Delay Issuance or Extend 

Compliance Time of Final Rule 

Kevin Lee requested that we delay 

issuance of the final rule, or extend the 

proposed 36-month compliance time 

specified in the NPRM (79 FR 11728, 

March 3, 2014). The commenter stated 

that Boeing has not incorporated the 

new GE autothrottle computer having 

part number (P/N) 760SUE2–5 into their 

Boeing 737 Illustrated Parts Catalog 

(IPC) or the Instructions for Continued 

Airworthiness documents. 

We disagree with delaying issuance of 

this final rule. Paragraph 1.K. of Boeing 

Alert Service Bulletin 737–22A1215, 

dated November 22, 2013, identifies the 

Boeing 737 IPC as the only document 

affected by replacement of the 

autothrottle computer. The new 

autothrottle computer has been added to 

the IPC, therefore there is no need to 

delay issuance of the final rule. 

We also disagree with extending the 

36-month compliance time. In 

developing an appropriate compliance 

time for this action, we considered the 

urgency associated with the subject 

unsafe condition, the availability of 

required parts, and the practical aspect 

of accomplishing the required 

modification within a period of time 

that corresponds to the normal 

scheduled maintenance for most 

affected operators. According to the 

manufacturer, an ample number of 

required parts will be available to 

modify the U.S. fleet within the 

proposed compliance time. However, 

under the provisions of paragraph (i) of 

this final rule, we will consider requests 

for approval of an extension of the 

compliance time if sufficient data are 

submitted to substantiate that the new 

compliance time would provide an 

acceptable level of safety. 

We have not changed the AD in 

regard to either delaying the final rule 

or extending the 36-month compliance 

time. 

Conclusion 

We reviewed the relevant data, 

considered the comments received, and 

determined that air safety and the 

public interest require adopting this AD 

as proposed except for minor editorial 

changes. We have determined that these 

minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (79 FR 

11728, March 3, 2014) for correcting the 

unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (79 FR 11728, 

March 3, 2014). 

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 497 

airplanes of U.S. registry. 

We estimate the following costs to 

comply with 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 

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.

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.
