## Discrepancy

DURING AN APPROVED PRECERTIFICATION MINI EVACUATION, THE L5 DOOR ESCAPE SLIDE & RAFT FAILED TO DEPLOY FROM THE ACFT & INFLATE PROPERLY.  INITIAL INVESTIGATION REVEALED THAT THE SLIDE PACK ASSEMBLY LANYARD, CONNECTING CABLE & PINS MECHANISM HAD FAILED TO RELEASE.  INITIAL INVESTIGATION AT THE ACFT REVEALED THAT WITH A SPRING TENSION PULL GAUGE ATTACHED TO THE LANYARD, WITH THE SLIDE PACK REMOVED FROM THE DOOR & BOTTLE SAFTIED, THE PACK CABLE & PINS MECHANISM WOULD NOT RELEASE.   REPAIRED IAW IAW CMM 25-66-05 R15.
