Narrative:
Aircraft left ZZZ for ZZZ1. Before arrival maintenance control called with a request for the weu to be changed due to intake heat warning. Aircraft arrived with no write-up. ZZZ is a line station operated by vendor. Overnight work was performed. Upon removing weu; noted that galley was missing upper inboard anchor pin; 1 of 3 installed. Weu retainers were not tight; easily turned with little finger pressure. Weu was replaced. Operational check of weu installed checks good. The issues were whether aircraft was flown with a known maintenance issue; whether it was documented in the first place before it left ZZZ and the fact that the galley was not secured. If the weu was removed; why wasn't it properly reinstalled and secured?callback conversation with reporter revealed the following information: the reporter stated the maintenance controller was contacted when no logbook item was written regarding the electronic warning control unit (weu). The controller insisted and directed the unit be replaced with no explanation or reason. The reporter indicated that the unit is located behind the galley module. When the galley was opened; it was discovered the upper galley anchor pin was missing and the warning control unit was not secured and locked in the bench plug. Reportedly; the unit was replaced and tested ok. The airplane was removed from service due to the galley upper anchor pin missing as the cabin attendant seat is attached to the galley module and cannot be deferred. The reporter believes the maintenance controller worked out a deal with the contract maintenance facility to get the airplane out of town and into a maintenance station where repairs could be accomplished. The reporter believes the intake heat warning was false and knew the warning unit was not secure and the galley anchor pin was missing; both items could not be deferred.

Title: A SAAB340 WAS DISPATCHED FROM A CONTRACT MAINT FACILITY WITH AN ELECTRONIC WARNING CTL UNIT NOT SECURED AND THE GALLEY MODULE NOT PROPERLY LATCHED.
Narrative: ACFT LEFT ZZZ FOR ZZZ1. BEFORE ARR MAINT CTL CALLED WITH A REQUEST FOR THE WEU TO BE CHANGED DUE TO INTAKE HEAT WARNING. ACFT ARRIVED WITH NO WRITE-UP. ZZZ IS A LINE STATION OPERATED BY VENDOR. OVERNIGHT WORK WAS PERFORMED. UPON REMOVING WEU; NOTED THAT GALLEY WAS MISSING UPPER INBOARD ANCHOR PIN; 1 OF 3 INSTALLED. WEU RETAINERS WERE NOT TIGHT; EASILY TURNED WITH LITTLE FINGER PRESSURE. WEU WAS REPLACED. OPERATIONAL CHK OF WEU INSTALLED CHKS GOOD. THE ISSUES WERE WHETHER ACFT WAS FLOWN WITH A KNOWN MAINT ISSUE; WHETHER IT WAS DOCUMENTED IN THE FIRST PLACE BEFORE IT LEFT ZZZ AND THE FACT THAT THE GALLEY WAS NOT SECURED. IF THE WEU WAS REMOVED; WHY WASN'T IT PROPERLY REINSTALLED AND SECURED?CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE MAINT CTLR WAS CONTACTED WHEN NO LOGBOOK ITEM WAS WRITTEN REGARDING THE ELECTRONIC WARNING CTL UNIT (WEU). THE CTLR INSISTED AND DIRECTED THE UNIT BE REPLACED WITH NO EXPLANATION OR REASON. THE RPTR INDICATED THAT THE UNIT IS LOCATED BEHIND THE GALLEY MODULE. WHEN THE GALLEY WAS OPENED; IT WAS DISCOVERED THE UPPER GALLEY ANCHOR PIN WAS MISSING AND THE WARNING CTL UNIT WAS NOT SECURED AND LOCKED IN THE BENCH PLUG. REPORTEDLY; THE UNIT WAS REPLACED AND TESTED OK. THE AIRPLANE WAS REMOVED FROM SVC DUE TO THE GALLEY UPPER ANCHOR PIN MISSING AS THE CABIN ATTENDANT SEAT IS ATTACHED TO THE GALLEY MODULE AND CANNOT BE DEFERRED. THE RPTR BELIEVES THE MAINT CTLR WORKED OUT A DEAL WITH THE CONTRACT MAINT FACILITY TO GET THE AIRPLANE OUT OF TOWN AND INTO A MAINT STATION WHERE REPAIRS COULD BE ACCOMPLISHED. THE RPTR BELIEVES THE INTAKE HEAT WARNING WAS FALSE AND KNEW THE WARNING UNIT WAS NOT SECURE AND THE GALLEY ANCHOR PIN WAS MISSING; BOTH ITEMS COULD NOT BE DEFERRED.
