Narrative:

On apr/xa/06; I was assigned to fix a captain's shoulder harness that was locking. We did not have the new harness at the line; so I made the decision to change the captain's seat assembly. The aircraft was a through-flight and boarding was held to quickly swap out the seat. The seat was changed using maintenance manual and the boarding hold was released. The following day; the flight crew wrote up the captain's seat missing 2 life vests. While trying to quickly dispatch the flight; the life vests located behind the captain's seat were not installed on the new seat. I was working another discrepancy on this flight and it was an oversight on my part to not ensure the life vests were swapped to the new seat.

Title: A B737-400 REQUIRED A CAPT'S SHOULDER HARNESS. NOT IN STOCK. REPLACED CAPT'S SEAT. DISPATCHED WITH REQUIRED LIFE VESTS MISSING FROM CAPT'S SEAT.

Narrative: ON APR/XA/06; I WAS ASSIGNED TO FIX A CAPT'S SHOULDER HARNESS THAT WAS LOCKING. WE DID NOT HAVE THE NEW HARNESS AT THE LINE; SO I MADE THE DECISION TO CHANGE THE CAPT'S SEAT ASSEMBLY. THE ACFT WAS A THROUGH-FLT AND BOARDING WAS HELD TO QUICKLY SWAP OUT THE SEAT. THE SEAT WAS CHANGED USING MAINT MANUAL AND THE BOARDING HOLD WAS RELEASED. THE FOLLOWING DAY; THE FLT CREW WROTE UP THE CAPT'S SEAT MISSING 2 LIFE VESTS. WHILE TRYING TO QUICKLY DISPATCH THE FLT; THE LIFE VESTS LOCATED BEHIND THE CAPT'S SEAT WERE NOT INSTALLED ON THE NEW SEAT. I WAS WORKING ANOTHER DISCREPANCY ON THIS FLT AND IT WAS AN OVERSIGHT ON MY PART TO NOT ENSURE THE LIFE VESTS WERE SWAPPED TO THE NEW SEAT.
