Narrative:
I had an instrument rated pilot handling the radios, as I was flying the 'ida (back crs) 60S', I'm not used to having help with the radios as I generally fly single pilot IFR. I misunderstood the heading given because I didn't read it back to the controller myself. I turned to a heading of 100 degree the controller asked for verification of heading and corrected the heading to 010 degree, then I was distraction by a short discussion with the other pilot as to that and the timing change. After that distraction things went downhill, I was turned inside of 'mages'. I started my descent and acquired the field visually then I realized I had descended below the step down altitude before I cancelled my IFR flight plan. Corrective action was to immediately stop descent and cancel flight plan. I think what could have prevented the several distrs that took place is if I had realized that when I'm not personally handling the radios that there is a greater chance of errors in understanding directions given by the controller. I think what could prevent this from happening again is clearly defining with the other pilot that I will repeat back heading and altitude for verification.
Original NASA ASRS Text
Title: PLT ON LDA APCH WITH RIGHT SEAT PLT PASSENGER ASSISTING WITH RADIO WORK, TURNS TO WRONG HEADING, DESCENDS BELOW PUBLISHED ALT.
Narrative: I HAD AN INSTRUMENT RATED PLT HANDLING THE RADIOS, AS I WAS FLYING THE 'IDA (BACK CRS) 60S', I'M NOT USED TO HAVING HELP WITH THE RADIOS AS I GENERALLY FLY SINGLE PLT IFR. I MISUNDERSTOOD THE HDG GIVEN BECAUSE I DIDN'T READ IT BACK TO THE CTLR MYSELF. I TURNED TO A HDG OF 100 DEG THE CTLR ASKED FOR VERIFICATION OF HDG AND CORRECTED THE HDG TO 010 DEG, THEN I WAS DISTR BY A SHORT DISCUSSION WITH THE OTHER PLT AS TO THAT AND THE TIMING CHANGE. AFTER THAT DISTR THINGS WENT DOWNHILL, I WAS TURNED INSIDE OF 'MAGES'. I STARTED MY DSCNT AND ACQUIRED THE FIELD VISUALLY THEN I REALIZED I HAD DSNDED BELOW THE STEP DOWN ALT BEFORE I CANCELLED MY IFR FLT PLAN. CORRECTIVE ACTION WAS TO IMMEDIATELY STOP DSCNT AND CANCEL FLT PLAN. I THINK WHAT COULD HAVE PREVENTED THE SEVERAL DISTRS THAT TOOK PLACE IS IF I HAD REALIZED THAT WHEN I'M NOT PERSONALLY HANDLING THE RADIOS THAT THERE IS A GREATER CHANCE OF ERRORS IN UNDERSTANDING DIRECTIONS GIVEN BY THE CTLR. I THINK WHAT COULD PREVENT THIS FROM HAPPENING AGAIN IS CLRLY DEFINING WITH THE OTHER PLT THAT I WILL REPEAT BACK HDG AND ALT FOR VERIFICATION.
