_**Background:**_
**FAA NW / Boeing informal meeting October 02, 2003.**
**Based upon the discussions it was concluded that industry should not become complacent on having the FAA Engine Nacelle Fire Simulator.**
**Notes: **From FAA NW / Boeing meeting**

_**Industry Should Not Become Complacent****_
**FAA Tech Center Plans To Evaluate / Test HFC-125 and CF3I.**
**FAA Have Requested That Industry Propose Additional Agents That They May Consider Using.**
**Concern Is That Once The Scheduled Testing Has Been Completed The FAA Funding For The Engine Nacelle Simulator May Possibly Not Continue.**

_**Industry Should Not Become Complacent****_
**If Funding Stops For The Simulator Could It Possibly Be Dismantled???**

_**Continued Need For FAA Engine Nacelle Fire Simulator**_
** ****There is considerable effort being extended in the     **
**  ****search for “Halon Alternatives”.**
** ****Army – helicopters – 5 agents being evaluated.**
** ****NIST –Next Generation Program (NGP)**
** ****NIST focusing on agents applicable to engine **
**  ****nacelles.**
** ****NGP effort is to demonstrate the performance **
**  ****of alternative agents by end of 2005.**

_**Continued Need For FAA Engine Nacelle Fire Simulator**_
** ****V-22 evaluating fire extinguishing agents.**
** ****Alternate Agent Working Group (AAWG) **
**  ****	****  ****research for “Halon Alternatives” including **
**  ****	****  ****agent 707.**
** ****Others including cargo groups are evaluating **
**        ****agents. **_**  **_

_**Continued Need For FAA Engine Nacelle Fire Simulator***_
** **
** ****Would expect that over the next two to three years **
**  ****that there will be two or more additional viable **
**  ****candidates for FAA Engine Nacelle Fire Simulator **
**  ****Tests.**
** ****Boeing Sees A Continuing Need For The FAA **

_**Recommendation:**_
** ****“****Boeing recommends to the FAA Tech Center that **
**   ****they continue to support and fund the FAA Engine **
**   ****Nacelle Fire Simulator for several years”  (2005 and **
**   ****beyond).**
