## Discrepancy

ON TAKE OFF, LANDING GEAR LEVER WOULD NOT RETRACT PAST THE OFF DETENT.   PERFORMED QRH PROCEDURE FOR LANDING GEAR LEVER LATCH FAILED TO RELEASE.    T/S PER 727-200 WDM 32-31-01. OHM CHECKED ENTIRE AIR & GROUND SENSOR CIRCUITS   FROM L/G ACCESSORY RACK PLUG AND CONFIRMED AN OPEN CIRCUIT INSIDE THE AIR   SENSING PROX SWITCH WHEN COMPARED TO A KNOWN NEW SWITCH.     R&R'D THE AIR SENSING PROX SWITCH SENSOR LOCATED ON LT GEAR PER 727-200 MM 32-09-  221-4 & OPS CHECKED AIR GROUND SENSE & LEVER LOCK CIRCUITS PER MM 32-09-221-5 AND   32-31-016-4. AIR SENSE MODE NOW FULLY FUNCTIONAL. LEVER LOCK RELEASES ON TEST &   L/G LEVER MOVES UP.
