## Discrepancy

RED CAUTION LIGHT COMES ON FOR OXYGEN SYSTEM - INTERMITTENT.  TROUBLESHOT SYSTEM TO COPILOT'S OXYGEN SYSTEM MICROSWITCH.  WHEN COPILOT'S SEAT WAS RAISED , END OF A SCREW PUSHED SWITCH CAUSING SWITCH TO MAKE CONTACT.  REMOVED COPILOT'S SEAT, CUT END OF SCREW OFF.  CHECKED SWITCH FOR PROPER ADJUSTMENT.  CHECKS GOOD.  OPERATED SEAT, NO INTERFERENCE WITH SWITCH.  RE-INSTALLED SEAT, RED LIGHT OUT.
