Unsafe Condition
An accumulation of gas, leaking from the reservoir regulator valve, initiated the slide enclosure door panel release and liberation of the slide in a non-inflated condition. Further investigation also determined that the most probable root cause of both panel and slide inflatable assembly release in flight is the blockage of one of the system venting features.
