Subtask 33-27-41-020-050-B ** ON A/C NOT FOR ALL
A. Removal of the Stand Alone Passenger Interface and Supply Adapter (StA-PISA)
NOTE: The removal procedure for the StA-PISA is the same. Only one procedure is given. For location of StA-PISA refer to (Ref. AMM D/O 33-27-00-00).
   (1) Do the subsequent steps to open the related circuit breaker panel:
WARNING: BE VERY CAREFUL WHEN YOU DO WORK ON CIRCUIT BREAKER PANELS. THERE IS A HIGH VOLTAGE BEHIND THESE PANELS.
     (a) Release the quick-release fasteners and lower the related circuit breaker panel carefully. The circuit breaker panel is held to the adjacent center ceiling panel by a detent hook.
     (b) Release the detent hook and lower one side of the related circuit breaker panel until it hangs in the vertical position.
   (2) Do the subsequent steps to remove the StA-PISA:
     (a) Identify the electrical connectors (6), (7) and (8) and make a note of their position before you disconnect them.
     (b) Release the related spring latches (4),(5) and (9) and carefully disconnect three electrical connectors (6), (7) and (8) from the StA-PISA (1).
     (c) Put the CAP-BLANKING on each disconnected electrical connector and receptacle.
     (d) Make a note of the position of the StA-PISA (1) before you remove it.
     (e) Make a note of the position of the cable clips which keep the related cable loom in position.
     (f) Hold the StA-PISA (1) and remove the screws (2), the washers (3) and the related cable clips.
     (g) Remove the StA-PISA (1).
     (h) If you do not install a new StA-PISA directly after the removal, make sure you close the related circuit breaker panel before you leave the A/C.
