Vol. 78, No. 185 

Tuesday, September 24, 2013 

DEPARTMENT OF TRANSPORTATION 

Federal Aviation Administration 

14 CFR Part 39 

[Docket No. FAA–2013–0792; Directorate 

Identifier 2013–NM–118–AD] 

RIN 2120–AA64 

Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for all The 

Boeing Company Model 737–600, –700, 

–700C, –800, –900, and –900ER series 

airplanes, and Model 777 airplanes. 

This proposed AD was prompted by 

testing reports on certain Honeywell 

phase 3 display units (DUs). These DUs 

exhibited susceptibility to radio 

frequency emissions in WiFi frequency 

bands at radiated power levels below 

the levels that the displays are required 

to tolerate for certification of WiFi 

system installations. The phase 3 DUs 

provide primary flight information 

including airspeed, altitude, pitch and 

roll attitude, heading, and navigation 

information to the flightcrew. This 

proposed AD would require replacing 

the existing phase 3 DUs with new 

phase 3A DUs and installing new DU 

database software. We are proposing 

this AD to prevent loss of flight-critical 

information displayed to the flightcrew 

during a critical phase of flight, such as 

an approach or takeoff, which could 

result in loss of airplane control at an 

altitude insufficient for recovery, or 

controlled flight into terrain or 

obstacles. 

DATES: We must receive comments on 

this proposed AD by November 8, 2013. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

SUPPLEMENTARY INFORMATION: 

Comments Invited 

We invite you to send any written 

relevant data, views, or arguments about 

this proposal. Send your comments to 

an address listed under the ADDRESSES

section. Include ‘‘Docket No. FAA– 

2013–0792; Directorate Identifier 2013– 

NM–118–AD’’ at the beginning of your 

comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of this proposed AD. We will 

consider all comments received by the 

closing date and may amend this 

proposed AD because of those 

comments. 

We will post all comments we 

receive, without change, to http://

www.regulations.gov, including any 

personal information you provide. We 

will also post a report summarizing each 

substantive verbal contact we receive 

about this proposed AD. 

Discussion 

This proposed AD resulted from 

instrumented testing on Model 737 

series airplanes that were equipped with 

certain Honeywell DUs. This testing 

determined that certain Honeywell 

phase 3 DUs exhibited flickering and 

blanking when subjected to radio 

frequency emissions in WiFi frequency 

bands at radiated power levels below 

those that the displays are required to 

tolerate for certification of a WiFi 

installation. Display blanking durations 

of as long as 6 minutes were observed 

during testing. The phase 3 DUs provide 

primary flight information including 

airspeed, altitude, pitch and roll 

attitude, heading, and navigation 

information to the flightcrew. These 

Honeywell phase 3 DUs are installed on 

certain Model 737 and Model 777 

airplanes. This condition, if not 

corrected, could result in loss of flightcritical information displayed to the 

flightcrew during a critical phase of 

flight, such as an approach or takeoff, 

which could result in loss of airplane 

control at an altitude insufficient for 

recovery, or controlled flight into terrain 

or obstacles. 

Relevant Service Information 

We reviewed Boeing Special 

Attention Service Bulletin 737–31– 

1471, dated November 29, 2012; and 

Boeing Special Attention Service 

Bulletin 777–31–0187, dated November 

29, 2012. For information on the 

procedures, see this service information 

at http://www.regulations.gov by 

searching for Docket No. FAA–2013– 

0792. 

FAA’s Determination 

We are proposing this AD because we 

evaluated all the relevant information 

and determined the unsafe condition 

described previously is likely to exist or 

mstockstill on DSK4VPTVN1PROD with PROPOSALS

58488 Federal Register / Vol. 78, No. 185 / Tuesday, September 24, 2013 / Proposed Rules 

develop in other products of the same 

type design. 

Proposed AD Requirements 

This proposed AD would require 

accomplishing the actions specified in 

the service information identified 

previously. 

Costs of Compliance 

We estimate that this proposed AD 

affects 157 airplanes of U.S. registry. 

We estimate the following costs to 

comply with this proposed AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Replacement (139 Model 737 airplanes) ..... 2 work-hours × $85 per hour = $170 ........... $10,200 $10,370 $1,441,430 

Replacement (18 Model 777 airplanes) ....... 3 work-hours × $85 per hour = $255 ........... 10,200 10,455 188,190 

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), 

(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.

contact the FAA’s Office of Rulemaking, 

(202) 267–9677, to request a copy of 

Advisory circular No. 11–2A, Notice of 

Proposed Rulemaking distribution 

System, which describes the application 

procedure. 

The Proposal 

The FAA is considering an 

amendment to Title 14, Code of Federal 

Regulations (14 CFR) part 71 to amend 

Class E airspace within a 7.2-mile 

radius, extending upward from 700 feet 

above the surface to support new 

Standard Instrument Approach 

Procedures developed at Warren County 

Memorial Airport, McMinnville, TN. 

Airspace reconfiguration is necessary 

due to the decommissioning of the 

Warri NDB and cancellation of the NDB 

approach, and for continued safety and 

management of IFR operations at the 

airport. 

Class E airspace designations are 

published in Paragraph 6005 of FAA 

Order 7400.9X, dated August 7, 2013, 

and effective September 15, 2013, which 

is incorporated by reference in 14 CFR 

71.1. The Class E airspace designation 

listed in this document will be 

published subsequently in the Order. 

The FAA has determined that this 

proposed regulation only involves an 

established body of technical 

regulations for which frequent and 

routine amendments are necessary to 

keep them operationally current. It, 

therefore, (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); and (3) does not warrant 

preparation of a Regulatory Evaluation 

as the anticipated impact is so minimal. 

Since this is a routine matter that will 

only affect air traffic procedures and air 

navigation, it is certified that this 

proposed rule, when promulgated, 

mstockstill on DSK4VPTVN1PROD with PROPOSALS
