A B737-700 MAINT SUPERVISOR NOTED THEIR MAINT PROCEDURES JOB CARD TO BE INCORRECT FOR CREW OXYGEN BOTTLE PRESSURE MINIMUMS.

Narrative

AS A SUPVR; I AM TASKED TO MAKE PAPERWORK CORRECTIONS. I RECEIVED A REQUEST FROM RECORDS. I READ THE INSTRUCTIONS FROM RECORDS. REVIEWED THE PAPERWORK; SINCE PAGE 2; BLOCK 3; STEP 1 SAID 2000 PSI. I ASSUMED PAGE 3; STEP 2 SHOULD BE N/A INSTEAD OF X. I CROSSED OUT AND INITIALED THE WRITE-UP CARD; AND LEFT PAGE 4 ALONE. RECORDS INFORMED ME THAT THE WRITE-UP CARD SHOULD BE ON PAGE 4 STEP B-4. I ARGUED A LITTLE ABOUT IT BUT COMPLIED WITH THEIR REQUEST. I FURTHER REVIEWED ALL OF THE PAPERWORK AND FOUND OUT THAT PAGE 2; 2000 PSI IS WRONG; PAGE 3 WAS CORRECT FROM THE GET GO; AND PAGE 4 ALSO WAS CORRECT BECAUSE THE MAINT FOR PRESSURE OXYGEN BOTTLE COVERS PAGE 4. I WAS NOT GOING TO ARGUE WITH RECORDS ANYMORE AND DECIDED THAT A RPT WOULD RESOLVE THIS WHOLE MESS; I ALSO THINK THAT I'M NOT THE ONLY PERSON THIS HAS HAPPENED TO. I AM ALSO GOING TO SUBMIT A CHANGE REQUEST TO FIX THE B-700 MAINT TIP XXXXXX; WHICH I THINK IS CONFUSING ALL THE MAINT VISITS. WHAT MAINT NEEDS TO SAY IS 'IF THE OXYGEN PRESSURE IS BELOW 1300 PSI AND/OR THE SYS FAILS THE OP CHK; YOU MUST COMPLY WITH XXXX.
