Gonzalez, Management Analyst, Business Operations Group, ANG–A12, Federal Aviation Administration. This notice announces a public teleconference to share with the public results of recent FAA sponsored testing of nitrous oxide (N2O) characteristics. Nitrous oxide is an important oxidizer to developers of some commercial reusable launch vehicles. A potential hazard in nitrous oxide storage and handling is a Boiling Liquid Expanding Vapor Explosion (BLEVE), which results from a sudden loss of pressure in a tank containing nitrous oxide stored under pressure above its normal boiling point. The FAA’s Office of Commercial Space Transportation sponsored tests of liquid-phase nitrous oxide at NASA’s White Sands Test Facility to empirically determine the superheat limit temperature for nitrous oxide, and to demonstrate that a BLEVE would not occur if the liquid is maintained at temperatures below this superheat limit temperature. Meeting Information: The teleconference is scheduled for Thursday, February 28, 2013, from 1:00–2:30 p.m. Eastern Standard Time. The presentation and call-in number will be posted one week in advance at http://www.ast.faa.gov/.

SUMMARY: This notice announces a public teleconference to share with 
the public results of recent FAA sponsored testing of nitrous oxide 
(N2O) characteristics. Nitrous oxide is an important 
oxidizer to developers of some commercial reusable launch vehicles. A 
potential hazard in nitrous oxide storage and handling is a Boiling 
Liquid Expanding Vapor Explosion (BLEVE), which results from a sudden 
loss of pressure in a tank containing nitrous oxide stored under 
pressure above its normal boiling point. The FAA's Office of Commercial 
Space Transportation sponsored tests of liquid-phase nitrous oxide at 
NASA's White Sands Test Facility to empirically determine the superheat 
limit temperature for nitrous oxide, and to demonstrate that a BLEVE 
would not occur if the liquid is maintained at temperatures below this 
superheat limit temperature.
    Meeting Information: The teleconference is scheduled for Thursday,
