ACR SUPVR RETURNED A HYD MULE TO SVC WITHOUT BEING PROPERLY CALIBRATED OR MAINTAINED.

Narrative

I WORK AT ACR X AT ZZZ AT THE SHOP. WE WORK ACFT CONTAINERS AND DO ON-CALL MAINT AROUND BASE. ALSO; WE RETURN EQUIP BACK TO THEIR SHOPS AND HANGARS. ON FEB/XA/01; WE WERE TOLD TO RETURN A HYD MULE BACK TO THE HANGARS. THEN WAS TOLD THE COMPANY WANTED A SAMPLE OF HYDROFLUID TAKEN. AFTER THAT CAME A SHIFT CHANGE -- WE WENT HOME. I LATER FOUND OUT A SAMPLE WAS TAKEN; AND THE UNIT WAS RETURNED BACK TO HANGARS FOR SVC. MY QUESTION IS THIS: IF THE COMPANY WAS TOLD THE UNIT OVERPRESSURIZED AT 3000 PSI CAUSING THE ACFT TO BLOW OUT 2 ENG PUMPS AND STEERING VALVES; WE HAVE A PROB. I HAVE 2 REPAIR ORDERS FOR THE HYDROUNIT FOR OVERPRESSURE. THE MECHS RAN THE UNIT IN OUR SHOP FOR OVER 1 HR AND HAD NO PROBS; SO THEY DID NOT CHANGE ANY PARTS LIKE THE FILTERS; YET MGMNT TOLD THEM TO TAKE A SAMPLE. A SAMPLE TAKES UP TO 90 DAYS TO GET RESULTS OF SAMPLE; YET OUR MGMNT RETURNS THIS UNIT BACK TO SVC WHEN THE UNIT MAY BE CONTAMINATED. ALSO; THE HYDROUNIT GAUGES ARE NOT CALIBRATED. SHOULD THEY BE CALIBRATED EVERY YR BECAUSE IT'S USED ON ACFT? ALSO; WHAT I THINK HAPPENED WAS THE MECHS AT THE HANGAR SET THE HYDROUNIT TO 3000 PSI ON MACH AND DID NOT CHK THE PRESSURE AT THE GAUGES ON THE ACFT ITSELF. I LATER HEARD THE PRESSURE IN THE ACFT WAS 3600 PSI. THE GAUGES IN THE HYDROUNIT MIGHT NOT BE SET RIGHT. DO WE HAVE PAPERWORK TO FIX A HYDROUNIT WHEN IT IS OR MAYBE CONTAMINATED AT ACR X.
