PIC of seneca asked me to file a flight plan for a flight departing crq en route to prb. He provided me with the details including TAS, route, estimated time and fuel on board. I filed the flight plan and listed him as PIC, as I was unfamiliar with the aircraft. The trip was uneventful until we got to the prb area. ZOA issued us a hold at the IAF for the VOR DME to prb. We entered the hold at 8000 ft in IMC. The seneca has limited icing protection and is placarded against flight into known icing conditions. The aircraft is not equipped with deicing boots. Shortly thereafter, with a temperature of -3 degrees C, ice started to accumulate on the windscreen and leading edge. We completed one turn in the hold and pilot remained silent. I reminded that the temperature was -3 degrees C and visible moisture was present. No action was taken by pilot. Upon entry into the second turn in the hold with no efc time, approximately 1/8 - 1/4 inch of ice had accumulated on the leading edge. I stated that we should not let this condition persist. I got on the radio and asked for a higher altitude. I could see that at 8000 ft, we were at the top of the cloud and VMC existed higher. ZOA, anticipating giving us a clearance past the IAF, asked us to remain at our present altitude. At that point, pilot transmitted over the radio that our deicing boots had failed and that we could continue VFR. ZOA gave us the clearance and we proceeded from the IAF in VFR conditions to prb and landed. There were several items that caused the problem. Pilot assumed that I got a WX brief for this flight. We did not communicate effectively in the cockpit or to ATC. Prior coordination would have changed the situation. He was the PIC. I had never flown with him and I have never flown a piper twin. Unclr roles and inaction adversely affected human performance.

Title: A PA34 SENECA II PLT GETS INTO ICING CONDITIONS WHILE HIS PAX, THE RPTR, TAKES OVER THE COM WHILE HOLDING AT KIKII INTXN NEAR PRB, CA.
Narrative: PIC OF SENECA ASKED ME TO FILE A FLT PLAN FOR A FLT DEPARTING CRQ ENRTE TO PRB. HE PROVIDED ME WITH THE DETAILS INCLUDING TAS, RTE, ESTIMATED TIME AND FUEL ON BOARD. I FILED THE FLT PLAN AND LISTED HIM AS PIC, AS I WAS UNFAMILIAR WITH THE ACFT. THE TRIP WAS UNEVENTFUL UNTIL WE GOT TO THE PRB AREA. ZOA ISSUED US A HOLD AT THE IAF FOR THE VOR DME TO PRB. WE ENTERED THE HOLD AT 8000 FT IN IMC. THE SENECA HAS LIMITED ICING PROTECTION AND IS PLACARDED AGAINST FLT INTO KNOWN ICING CONDITIONS. THE ACFT IS NOT EQUIPPED WITH DEICING BOOTS. SHORTLY THEREAFTER, WITH A TEMP OF -3 DEGS C, ICE STARTED TO ACCUMULATE ON THE WINDSCREEN AND LEADING EDGE. WE COMPLETED ONE TURN IN THE HOLD AND PLT REMAINED SILENT. I REMINDED THAT THE TEMP WAS -3 DEGS C AND VISIBLE MOISTURE WAS PRESENT. NO ACTION WAS TAKEN BY PLT. UPON ENTRY INTO THE SECOND TURN IN THE HOLD WITH NO EFC TIME, APPROX 1/8 - 1/4 INCH OF ICE HAD ACCUMULATED ON THE LEADING EDGE. I STATED THAT WE SHOULD NOT LET THIS CONDITION PERSIST. I GOT ON THE RADIO AND ASKED FOR A HIGHER ALT. I COULD SEE THAT AT 8000 FT, WE WERE AT THE TOP OF THE CLOUD AND VMC EXISTED HIGHER. ZOA, ANTICIPATING GIVING US A CLRNC PAST THE IAF, ASKED US TO REMAIN AT OUR PRESENT ALT. AT THAT POINT, PLT XMITTED OVER THE RADIO THAT OUR DEICING BOOTS HAD FAILED AND THAT WE COULD CONTINUE VFR. ZOA GAVE US THE CLRNC AND WE PROCEEDED FROM THE IAF IN VFR CONDITIONS TO PRB AND LANDED. THERE WERE SEVERAL ITEMS THAT CAUSED THE PROB. PLT ASSUMED THAT I GOT A WX BRIEF FOR THIS FLT. WE DID NOT COMMUNICATE EFFECTIVELY IN THE COCKPIT OR TO ATC. PRIOR COORD WOULD HAVE CHANGED THE SIT. HE WAS THE PIC. I HAD NEVER FLOWN WITH HIM AND I HAVE NEVER FLOWN A PIPER TWIN. UNCLR ROLES AND INACTION ADVERSELY AFFECTED HUMAN PERFORMANCE.
