SF340 CHECK CAPT WITH FO ON FIRST DAY OF IOE; REPORTS WING DE-ICE SYSTEM FAILURE DURING DESCENT. CAPT DOES QRH PROCEDURES FROM MEMORY FINISHES NORMAL CHECKLISTS. SAFE LANDING ENSUES WITH ICE ADHERING TO WING.

Narrative

WHILE DSNDING INTO THE CLOUDS AT APPROX 7000 FT; WE STARTED ACCUMULATING MODERATE RIME ICE. I SELECTED THE BOOTS TO CONTINUOUS; AND WE RECEIVED A TIMER LIGHT. IT WAS THE FO'S FIRST FLT ON IOE; AND I (CAPT AND PF) ELECTED TO HAVE HIM CONTINUE WITH THE DSCNT AND APCH CHKLISTS INSTEAD OF GOING TO THE QRH; BECAUSE WE WERE BEING VECTORED FOR THE APCH; AND NOT TOO FAR FROM BEING ABLE TO JOIN THE LOC; AND THE FO WAS STILL QUITE SOME TIME FROM FINISHING THE CHKLISTS. WHILE THE FO WORKED ON CHKLISTS; I WAS BASICALLY SINGLE PLT; FLYING AND WORKING THE RADIO (WHICH HAPPENS OFTEN ON THE FIRST DAY OF IOE). BEING FAMILIAR WITH WHAT THE QRH SAYS TO DO; I ELECTED TO TRY TO GET THE BOOTS TO WORK; BECAUSE OF THE ACCUMULATION RATE; AND THE TIME WE HAD LEFT. I CHKED THAT THE HP'S WERE ON (THEY WERE); I TRIED THE 1 CYCLE MODE (IT DIDN'T WORK); I TRIED THE MANUAL MODE (IT DIDN'T WORK); WE CHKED THE CIRCUIT BREAKERS (THEY WERE ALL IN). BECAUSE OF THE ICE ACCUMULATION; AND THE UNCERTAINTY OF HOW MUCH ICE WE WOULD CONTINUE TO ACCUMULATE WHILE IMC; AND THE FACT THAT NO BOOT OP SEEMED TO WORK; I ELECTED TO JOIN THE APCH; AND LAND WITHOUT RUNNING THE QRH. THE FO STARTED THE CHKLISTS AT ABOUT 70 MI FROM CAK; AND DIDN'T FINISH UNTIL ABOUT A 5 MI FINAL; WHICH DIDN'T ALLOW FOR ANY QRH TIME. I BRIEFED THE APCH WITH A VREF +20 SPD FOR WHAT I REMEMBERED AS A CORRECTION FROM THE QRH WITH ICE ACCUMULATION; AND NO BOOT OP. AT APPROX 3000 FT; WE GOT BELOW THE BASES (ON THE ILS); AND WERE IN MODERATE SNOW SHOWERS (WE SAW THE ARPT ON ABOUT A 1-2 MI FINAL); AND SEEMED TO ONLY BE ACCUMULATING IMPACT SNOW ON TOP OF APPROX 1/3 OF AN INCH OF ICE (I DSNDING FAIRLY RAPIDLY FROM 7000 FT TO OUR ASSIGNED ALT OF 3200 FT; TO TRY AND GET OUT OF THE MODERATE ICING). AFTER LNDG IN CAK; AFTER SHUTDOWN; WE FINISHED THE QRH FOR ICE PROTECTION. I WOULD HAVE RATHER BEEN ABLE TO FINISH THE QRH IN THE AIR; BUT I DIDN'T WANT TO CLB BACK INTO THE CLOUDS WITHOUT ANY BOOT PROTECTION; SO I ELECTED TO LAND; AS I THOUGHT THIS WAS THE SAFEST POSSIBLE OUTCOME FOR OUR FLT. POSSIBLY START DSCNT AND APCH CHKLISTS SOONER; BUT IT IS DIFFICULT TO KNOW HOW MUCH TIME IS NEEDED. THE FLT WAS FAIRLY SHORT; AND WHEN THE FO WASN'T RUNNING CHKLISTS; I WAS TEACHING HIM WHAT WAS NEXT (FOLLOW FMS WITH 2ND COURSE; GET ATIS; CALL OPS; BRIEF PAX; ETC).
