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 certain 

The Boeing Company Model 757 and 

Model 767 airplanes. This proposed AD 

was prompted by a standby power relay 

failure and subsequent illumination of 

the ‘‘STANDBY BUS OFF’’ light, which 

led the flightcrew to set the standby 

power switch to the ‘‘BAT’’ position, 

isolating the battery and standby buses, 

disabling the battery charger, and 

eventually causing the main battery to 

be depleted. This proposed AD would 

require doing wiring changes and 

installing a new air/ground relay to the 

battery charger system. We are 

proposing this AD to prevent discharge 

of the main battery, which could result 

in multiple system degradation, reduced 

airplane controllability, and runway 

excursion upon landing. 

DATES: We must receive comments on 

this proposed AD by February 4, 2013. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

about this proposed AD. 

Discussion 

During a flight on a Model 757 

airplane, the ‘‘STANDBY BUS OFF’’ 

indication light illuminated due to 

failure of the standby power relay. 

Following the Quick Reference 

Handbook (QRH) instructions, the 

flightcrew set the standby power switch 

to the ‘‘BAT’’ position, and continued 

with the flight. By design, this action 

isolated the 28 volt direct current (VDC) 

hot battery bus, 28 VDC battery bus, 28 

VDC standby bus, and 115 volt 

alternating current (VAC) standby bus; 

disabled the battery charger; and caused 

the main battery alone to power the 

standby buses (115 VAC and 28 VDC). 

The flight continued beyond the battery 

limit causing the main battery to be 

depleted with consequent loss of power 

to the battery/standby buses and the 

systems associated with them. On 

approach, the flightcrew found that the 

horizontal stabilizer trim was not 

available, and that the lateral control 

was degraded. Upon landing, the 

speedbrakes only partially deployed, 

reverse thrust was unavailable, one-half 

of the flight spoilers and all the ground 

spoilers were inoperative, and all four 

inboard tires blew due to the loss of 

inboard anti-skid. When the airplane 

stopped, the engines could not be 

powered off using standard procedures. 

We have determined that Model 767 

airplanes are similar in design to Model 

757 airplanes; therefore, this unsafe 

condition might also occur on certain 

Model 767 airplanes. This condition, if 

not corrected, could result in discharge 

of the main battery, which could result 

in multiple system degradation, reduced 

airplane controllability, and runway 

excursion upon landing. 

Relevant Service Information 

We reviewed Boeing Special 

Attention Service Bulletin 757–24– 

0132, Revision 1, dated June 19, 2012; 

and Boeing Special Attention Service 

Bulletin 767–24–0200, Revision 1, dated 

September 13, 2012. For information on 

the procedures and compliance times, 

see this service information at http:// 

www.regulations.gov by searching for 

Docket No. FAA–2012–1229. 

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 

develop in other products of the same 

type design. 

Proposed AD Requirements 

This proposed AD would require 

accomplishing the actions specified in 


erowe on DSK2VPTVN1PROD with 
Federal Register / Vol. 77, No. 245 / Thursday, December 20, 2012 / Proposed Rules 75403 

the service information described 

previously. 

The phrase ‘‘related investigative 

actions’’ might be used in this proposed 

AD. ‘‘Related investigative actions’’ are 

follow-on actions that (1) are related to 

the primary action, and (2) are actions 

that further investigate the nature of any 

condition found. Related investigative 

actions in an AD could include, for 

example, inspections. 

In addition, the phrase ‘‘corrective 

actions’’ might be used in this proposed 

AD. ‘‘Corrective actions’’ are actions 

that correct or address any condition 

found. Corrective actions in an AD 

could include, for example, repairs. 

Costs of Compliance 

We estimate that this proposed AD 

affects 1,085 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 

Install new air/ground relay, 674 

Model 757 airplanes.

23 work-hours × $85 per hour = 

$1,955.

Up to $733 ............ Up to $2,688 ......... Up to $1,811,712. 

Install new air/ground relay, 411 

Model 767 airplanes.

Up to 35 work-hours × $85 per hour = 

$2,975.

Up to $881 ............ Up to $3,856 ......... Up to $1,584,816. 

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.

Background 

1. The NPRM in this proceeding 

established a comment deadline of 

December 18, 2012 and a reply 

comment deadline of December 28, 

2012. On December 6, 2012, the 

Consumer Electronics Association 

(CEA), the National Association of 

Broadcasters (NAB), and the National 

Cable & Telecommunications 

Association (NCTA) jointly requested 

that the reply comment deadline be 

extended by ten days, due to the 

expected volume of comments, 

discussion, and data on the complex 

issues raised in this proceeding, as well 

as the groundbreaking nature of those 

issues. We grant the requested 

extension. 

2. As set forth in Section 1.46 of the 

Commission’s Rules, 47 CFR 1.46, the 

Commission’s policy is that extensions 

of time for filing comments in 

rulemaking proceedings shall not be 

routinely granted. Given the importance 

of the issues in this proceeding and in 

the interest of encouraging thoughtful 

consideration of these issues, however, 

we believe that granting the joint 

request is warranted to provide 

commenters with sufficient time to 

prepare reply comments in response to 

the NPRM and to facilitate the 

development of a more complete record.
