SUPPLEMENTARY INFORMATION: 

Background 

Section 917 of the approved FAA 

Modernization and Reform Act of 2012, 

H.R. Bill 658, requires the FAA to 

identify bleed air purification 

technology. Specifically, the FAA seeks 

information about bleed air cleaning, 

and contaminant detection and 

recording technologies which are 

capable of removing oil-based 

contaminants from the bleed air 

supplied to the passenger cabin and 

flight deck, and detecting and recording 

oil-based contaminants in the total air 

supplied to the passenger cabin and 

flight deck from bleed air. 

The FAA recognizes there are various 

design concepts used by both 

developers and manufacturers of cabin 

air environmental control units. Given 

the design and performance variation in 

these technologies, the FAA seeks 

information from the industry to assist 

in its evaluation of the types of air 

cleaning and monitoring technology that 

will successfully detect, remove and 

report on engine-produced, oil-based 

cabin air contaminants. 

Request for Information 

The FAA requests that the comments 

specifically address the following areas 

to this notice: 

• Design and operational description 

• Physical dimensions of the device(s), 

including weight 

• Power, interconnect, and other 

installation requirements 

• Operational dimensions for the 

technology/system 

• Maintenance needs to assure system 

performance 

• Safety mechanisms designed into the 

technology/system to minimize or 

mitigate anticipated hazards 

For detection technologies, please 

identify: 

• Contaminants the device can detect 

and sensitivity for each 

• Location of the detection device 

placed in the air distribution system 

For air cleaning technologies, please 

identify: 

• Contaminants the device can remove 

• Overall system capacity 

• Cleaning effectiveness for each 

contaminant 

Again, this information must be 

submitted by September 17, 2012. 

Comments Invited 

The FAA invites interested persons to 

submit written comments, data, or 

views. The most helpful comments 

reference a specific area of concern, 

explain the reason for any 

recommended change, and include 

supporting data. To ensure the docket 

does not contain duplicate comments, 

commenters should send only one copy 

of written comments, or if comments are 

filed electronically, commenters should 

submit only one time. 

The FAA will file in the docket all 

comments it receives, as well as a report 

summarizing each substantive public 

contact with FAA personnel concerning 

this notice. The FAA will consider all 

comments it receives on or before the 

closing date for comments. The FAA 

will consider comments filed after the 

comment period has closed if it is 

possible to do so without incurring 

expense or delay. 

Proprietary or Confidential Business

Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Supplemental notice of 

proposed rulemaking (NPRM); 

reopening of comment period. 

SUMMARY: We are revising an earlier 

proposed airworthiness directive (AD) 

for certain The Boeing Company Model 

737–600, –700, –700C, –800, and –900 

series airplanes. That NPRM proposed 

to require inspecting the orientation of 

both sides of the coil cord connector 

keyways of the number 2 windows on 

the flight deck; re-clocking the 

connector keyways to 12 o’clock, if 

necessary; and replacing the coil cord 

assemblies on both number 2 windows 

on the flight deck. That NPRM was 

prompted by reports of arcing and 

smoke at the left number 2 window in 

the flight deck. This action revises that 

NPRM by changing the keyway position 

of certain receptacle connectors and 

adding airplanes to the applicability. 

We are proposing this supplemental 

NPRM (SNPRM) to prevent arcing, 

smoke, and fire in the flight deck, which 

could lead to injuries to or 

incapacitation of the flightcrew. Since 

these actions impose an additional 

burden over that proposed in the NPRM, 

we are reopening the comment period to 

allow the public the chance to comment 

on these proposed changes. 

DATES: We must receive comments on 

this supplemental NPRM by August 31, 

2012. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods: 

• Federal eRulemaking Portal: Go to 

http://www.regulations.gov. Follow the 

instructions for submitting comments. 

• Fax: 202–493–2251. 

• Mail: U.S. Department of 

Transportation, Docket Operations,

Discussion 

We issued an NPRM to amend 14 CFR 

part 39 to include an AD that would 

apply to The Boeing Company Model 

737–600, –700, –700C, –800, and –900 

series airplanes, as identified in Boeing 

Special Attention Service Bulletin 737– 

30–1058, Revision 3, dated July 7, 2010. 

That NPRM published in the Federal 

Register on January 26, 2011 (76 FR 

4567). That NPRM proposed to require 

inspecting the orientation of both sides 

of the coil cord connector keyways of 

the number 2 windows on the flight 

deck; re-clocking the connector keyways 

to 12 o’clock, if necessary; and replacing 

the coil cord assemblies on both number 

2 windows on the flight deck. 

Actions Since Previous NPRM (76 FR 

4567, January 26, 2011) Was Issued 

Since we issued the previous NPRM 

(76 FR 4567, January 26, 2011), we have 

received three reports by operators of 

wire connectors at the two ends of the 

coil cord rubbing each other. These 

operators had accomplished the actions 

described in Boeing Special Attention 

Service Bulletin 737–30–1058, Revision 

3, dated July 7, 2010 (or earlier 

revisions), which was referred to in the 

previous NPRM as the appropriate 

source of service information. The rub 

condition occurs when the window 

opens or is in the fully open position. 

The rub condition can possibly cause 

damage to the wire connector and the 

coil cord and cause arcing, smoke, and 

fire in the flight deck, which could lead 

to injuries to or incapacitation of the 

mstockstill on DSK4VPTVN1PROD with PROPOSALS
