It is DOE’s policy that all comments 

may be included in the public docket, 

without change and as received, 

including any personal information 

provided in the comments (except 

information deemed to be exempt from 

public disclosure). 

B. Issues on Which DOE Seeks Comment 

Although DOE welcomes comments 

on any aspect of this notice, DOE is 

particularly interested in receiving 

comments and views of interested 

parties concerning the following issues: 

(1) The conclusion that after removing 

0.8 percent NEMA’s reduction factor 

and recalculating lamp arc powers, the 

remaining differences between DOE and 

NEMA-provided data are likely due to 

normal measurement variation; 

(2) The methodology used to account 

for compliance certification 

requirements and measurement 

variation in developing efficiency 

levels; 

(3) The appropriateness of using a 

power law equation to develop 

efficiency levels and the chosen values 

for the exponent ‘‘C’’; and 

(4) The efficiency levels considered. 

VII. Approval of the Office of the 

Secretary 

The Secretary of Energy has approved 

publication of this notice of data 

availability.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

model 767–200, –300, and –300F series 

airplanes. This proposed AD would 

require doing certain wiring changes, 

installing a new relay and necessary 

wiring in the cabin air conditioning and 

temperature control system (CACTCS), 

and performing an operational test of 

the cooling pack fire suppression 

system. This AD results from reports of 

loss of avionics cooling due to an 

unserviceable relay installed on a panel 

as part of the CACTCS. We are 

proposing this AD to prevent loss of 

electrical equipment bay cooling and 

the overheating of flight deck 

instruments, which would result in the 

eventual loss of primary flight displays, 

an unusually high pilot workload, and 

depressurization of the cabin. 

DATES: We must receive comments on 

this proposed AD by October 11, 2011. 

ADDRESSES: You may send comments by

personal information you provide. We 

will also post a report summarizing each 

substantive verbal contact we receive 

about this proposed AD. 

Discussion 

We received reports of loss of avionics 

cooling due to an unserviceable relay. 

This relay was one of six relays installed 

on a panel as part of the CACTCS. The 

failure of this relay caused a smoke 

mode solenoid to energize, causing the 

air conditioning system to go into a 

Class E fire suppression mode, the right 

side of the relay pack to turn off, and the 

left-side relay pack to go into low-flow 

mode. Over time, this caused 

insufficient equipment cooling and the 

slow depressurization of the cabin. This 

condition, if not corrected, could result 

in loss of electrical equipment bay 

cooling and the overheating of flight 

deck instruments, which would result 

in the eventual loss of all primary flight 

displays, an unusually high pilot 

workload, and depressurization of the 

cabin. 

Relevant Service Information 

We reviewed Boeing Special 

Attention Service Bulletins 767–21– 

0246, dated January 7, 2011 (for Model 

767–200 and 767–300 series airplanes); 

and 767–21–0234, dated August 6, 2009 

(for Model 767–300F series airplanes). 

These service bulletins describe 

procedures for changing the wire bundle 

route and wiring, installing a new relay 

and applicable wiring in the CACTCS, 

and doing an operational test of the 

cooling pack fire suppression system.

FAA’s Determination and Proposed AD 

Requirements 

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 these same 

type designs. This proposed AD would 

require accomplishing the actions 

specified in the service information 

described previously. 

Costs of Compliance 

We estimate that this proposed AD 

affects 35 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 

Change wire bundle, install relay, and operational 

test.

29 work-hours × $85 per hour = $2,465 per relay 

installation.

$1,240 $3,705 $129,675 

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.

Airworthiness Directives; The Boeing 

Company Model 757–200, –200PF, and 

–200CB Series Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede an 

existing airworthiness directive (AD) 

that applies to the products listed above. 

The existing AD currently requires 

repetitive inspections of the shim 

installation between the engine strut 

vertical flange and bulkhead, and repair 

if necessary. The existing AD also 

requires, for certain airplanes, an 

inspection for cracking of the four 

critical fastener holes in the horizontal 

flange, and repair if necessary. 

Additionally, the existing AD requires 

that the existing action be performed on 

airplanes without conclusive records of 

previous inspections. Since we issued 

that AD, we have received reports of 

loose fasteners and cracks at the joint 

common to the aft torque bulkhead and 

strut-to-diagonal brace fitting and one 

report of such damage occurring less 

than 3,000 flight cycles after the last 

inspection. This proposed AD would 

reduce the repetitive inspection 

interval, and add repetitive detailed 

inspections for cracking of the 

bulkhead, and repair if necessary. This 

proposed AD would also provide an 

option, for certain airplanes, to extend 

the repetitive intervals by also doing 

repetitive ultrasonic inspections for 

cracking of the bulkhead, and repair if 

necessary. This proposed AD would 

also add an option for the high 

frequency eddy current inspection for 

cracking of the critical fastener holes, 

and repair if necessary. We are 

proposing this AD to detect and correct 

cracks, loose and broken bolts, and shim 

migration in the joint between the aft 

torque bulkhead and the strut-todiagonal brace fitting, which could 

result in damage to the strut and 

consequent separation of the strut and 

engine from the airplane.

this proposed AD by October 11, 2011.

Discussion 

On February 22, 2008, we issued AD 

2008–05–10, Amendment 39–15404 (73 

FR 11347, March 3, 2008), for certain 

Boeing Model 757–200, –200PF, and 

–200CB series airplanes powered by 

Rolls-Royce engines. That AD requires 

repetitive inspections of the shim 

installation between the engine strut 

vertical flange and bulkhead, and repair 

if necessary. That AD also requires, for 

certain airplanes, an inspection for 

cracking of the four critical fastener 

holes in the horizontal flange, and 

repair if necessary. That AD resulted 

from reports of cracking in the pylon 

under bolts that appear to be 

undamaged during the existing AD 

inspections. That AD also resulted from 

our determination that operators did not 

maintain records of previous 

inspections that are necessary to 

determine the appropriate corrective 

actions. We issued that AD to detect and 

correct cracks, loose and broken bolts, 

and shim migration in the joint between 

the aft torque bulkhead and the strut-todiagonal brace fitting, which could 

result in damage to the strut and 

consequent separation of the strut and 

engine from the airplane. 

Actions Since Existing AD Was Issued 

Since we issued AD 2008–05–10, we 

have received reports of loose fasteners 

and cracks at the joint common to the 

aft torque bulkhead and strut-todiagonal brace fitting and one report of
