Narrative

I WAS PIC ON A FLT FROM CDC (CEDAR CITY) TO SALT LAKE CITY; UT; WITH AN FAA INSPECTOR SEATED NEAR THE REAR OF ACFT. ON LNDG AT CDC WE ENCOUNTERED LIGHT SNOW AND A WET RWY. AFTER ARRIVING AT THE GATE AND TAKING ON 1 PAX; I NOTICED A THIN LAYER OF SNOW COLLECTING ON THE WINGS. I HAD THE FO TAKE A LAMINATED CHKLIST CARD 8 1/2 X 11 INCHES AND SCRAPE ALONG BOTH WINGS TO VERIFY THAT NONE OF THE LIGHT SNOW WAS ADHERING TO THE WINGS. WE ELECTED TO TAXI OUT AND TKOF BELIEVING THE SNOW WOULD QUICKLY BLOW OFF WHEN THE TKOF ROLL BEGAN. IT WAS AGREED THAT IF THE SNOW DID NOT COME FREE; THE TKOF WOULD BE TERMINATED AT 80 KTS. AT APPROX 60 KTS I GLANCED BACK AT THE L WING AND SAW NO CONTAMINANTS ADHERING TO THE WING; AND TOLD THE FO WHO WAS CONDUCTING THE TKOF; TO CONTINUE. ON ARR AT SALT LAKE CITY THE FAA INSPECTOR CAME TO THE COCKPIT AND ANNOUNCED THERE HAD BEEN A THIN COAT OF ICE ON REAR PORTION OF WINGS DURING TKOF. HE SEEMED UNHAPPY OVER THE WAY THE SITUATION WAS HANDLED. THE TKOF WAS CONDUCTED AT NEAR GROSS WT AND ACFT PERFORMED EXTREMELY WELL IN THE CLB. SURFACE TEMP AT THE TIME WAS APPROX 33 DEGS F.
