FLC OF AN MDT ACR ACFT EXPERIENCED A STUCK MIKE.

Narrative

UPON PICKING THE ACFT IN CLT FOR OUR TRIP TO CVG WE WERE INFORMED BY MAINT THAT THE CAPT'S PUSH-TO-TALK SWITCH LOCATED ON THE STEERING TILLER WAS RPTED AS BEING INOP BY THE PREVIOUS CREW. AS THERE IS ANOTHER PUSH-TO-TALK SWITCH ON THE CAPT'S YOKE; MAINT DEFERRED THE TILLER SWITCH. WE TOOK OFF FOR CVG AND THE TRIP WAS UNEVENTFUL. THERE WAS SOME RIME ICING ON FINAL. I BLEW THE DEICING BOOTS ON BREAKING OUT IN CVG IN ORDER TO CLR ANY REMAINING ICE. TEMP ON THE GND WAS 37 DEGS F AT THE TIME OF LNDG. AS I WAS GETTING THE CLRNC; THE FO INFORMED ME THAT THERE WAS A LITTLE RESIDUAL SLUSHY ICE ON THE L WING THAT HAD NOT MELTED. I FINISHED READING THE CLRNC BACK TO ATC AND THEN DISCUSSED THE SIT WITH HIM. I THEN LOOKED DOWN AT THE #2 COM SWITCH AND REALIZED THAT THE MIKE SWITCH WAS STUCK. I CLICKED THE TILLER SWITCH ON AND OFF THINKING THAT I MAY HAVE USED IT INADVERTENTLY WHEN GETTING THE CLRNC. THE XMIT LIGHT THEN WENT OUT AND ATC COMMENTED ON THE HOT MIKE. AFTER WE WERE AIRBORNE WE BEGAN TO DISCUSS THE HOT MIKE INCIDENT. I COMMENTED THAT WE NEVER GAVE ANY CALL SIGNS AND THEY PROBABLY DIDN'T KNOW WHO IT WAS; BESIDES THE REMAINING ICE HAD FALLEN OFF THE WING AS WE KNEW IT WOULD; SO THERE WAS NOTHING TO CONCERN OURSELVES WITH. AT THIS MOMENT; I DISCOVERED THAT THE MIKE HAD STUCK ON XMIT AGAIN EVEN THOUGH I HAD NOT USED THE TILLER SWITCH. NEEDLESS TO SAY WE SPENT THE ENTIRE TRIP REVIEWING OUR EVERY WORD; EVEN THOUGH; EXCEPT FOR THE STUCK MIKE; THE WHOLE THING WAS A NON-EVENT. THE BOTTOM LINE IS THAT PLTS TODAY LIVE IN CONSTANT FEAR OF AN FAA VIOLATION AND ANYTHING THAT EVEN REMOTELY RAISES THE SPECTER OF A VIOLATION PROVOKES SO MUCH DISCUSSION THAT THE PRIMARY JOB OF FLYING IS OFTEN LEFT ON THE BACK BURNER; WHICH CAN LEAD TO THE EVEN WORSE PROB OF MINOR INCIDENTS COMPOUNDING INTO MAJOR PROBS.
