Narrative

AFTER ARR IN ACFT IN ZZZ; CREW NOTIFIED MAINT THAT THE STANDBY PWR XFER SWITCH ON THE OVERHEAD PANEL DID NOT WORK PROPERLY. IN BAT POSITION; CAPT'S NAV PANEL OPERATED NORMALLY. ESS BUS WAS POWERED. HOWEVER; IN STANDBY POSITION; CAPT NAV PANEL UNPOWERED. MY LEAD DIRECTED ME TO CHANGE 2 ITEMS; THE M328 RELAY BEHIND THE P6 PANEL AND THE STATIC INVERTER IN THE E & E BAY. I STARTED CHANGING THE RELAY; AND MY LEAD CHOSE TO REPLACE THE STATIC INVERTER HIMSELF. AS I WAS SECURING THE P6 PANEL; MY LEAD RETURNED THE POWER TO THE ACFT. I CHKED THE STANDBY POWER TRANSFER. IT STILL DID NOT WORK. MY LEAD SAID IT WAS OK AND THAT HE HAD ALREADY SIGNED OFF THE LOGBOOK ITEM. I TOLD HIM THE PROB STILL EXISTED. HE SAID IT WAS OK AND IF IT DID 'RETURN' THAT THE PLANE WAS JUST MAKING A ROUND TRIP. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR TESTED THE STANDBY POWER SYSTEM ON ARR AND DID NOT SWITCH PROPERLY IN AUTO MODE TO POWER THE CAPT'S NAVIGATION PANEL. TWO UNITS WERE CHANGED; THE M328 RELAY AND THE STATIC INVERTER. THE RPTR REPLACED THE M328 RELAY WHILE THE LEAD REPLACED THE STATIC INVERTER. THE PAPERWORK WAS CLRED BY THE LEAD TECHNICIAN WHILE THE RPTR WAS STILL REPLACING THE RELAY. THE RPTR TESTED THE STANDBY POWER SYSTEM IN AUTO AND IT FAILED. THE RPTR STATED THE LEAD TECHNICIAN WAS ADVISED THE STANDBY POWER SYSTEM WAS STILL INOP IN AUTO AND WAS NOT FIXED. THE RPTR CLAIMS THE LEAD DISPATCHED THE AIRPLANE KNOWING THE STANDBY POWER SYSTEM DID NOT OPERATE NORMALLY.
