1. System did not Hre; inflator assemblies leaked, causing firing 

 pressure to drop to less than 400 psi, which is the minimum 

 pressure required. 



2. Problem was not determined until after test operation; the 

 inflator assembly has since been eliminated, and procedures to 

 detect any form of leakage have been outlined.
