Narrative:

We landed in mci on a flight from slc dec/xx/96. On this approach or descent we penetrated a thin layer of clouds with light ice. We used engine anti-ice and only had a slight ice indication. We taxied into the gate at mci. Another of our xyz aircraft was being deiced. All xyz ramp spaces had deice fluid on it. After the engines were shut down I received a chocks signal and released the brakes. The aircraft moved and brakes were instantly reapplied. I went outside and found the deicing fluid on the ramp caused the chocks to slip. The so was briefed to check for ice on his walkaround. I then went to exit row 20 and 22 and checked over the wing tops on both sides of the aircraft. The wings were clean of all ice. The so reported that his walkaround showed the aircraft clean. The first officer and I checked the front of the aircraft from the gate house, and the aircraft appeared clean. I then made a captain's decision that we did not need deicing for flight xx to atl from mci. FAA maintenance inspector came up the aft airstair unannounced. We challenged his identify when he came to the cockpit. He was from the FAA to inspect maintenance. I told him to go ahead. Just prior to push back for flight, one of our ground crew came to the cockpit and asked when do we want to be deiced. We told him that the aircraft was checked and did not need deicing. When we pushed flight xx back from the gate FAA inspector pulled his car in front of the jetway and watched us start engines and leave. Later I learned after I flew an uneventful flight to atlanta, that the FAA inspector wanted all ground crew and flight crew names and he was furious we did not deice. I as the captain made a reasonable and extra checks that this aircraft did not need deicing. It was in clear dry air and over 10 mi visibility. If this inspector for the FAA thought we were unsafe he should have prevented the takeoff. Otherwise he was just trying to set us up, but if he noticed something that I or my crew did not he should have brought it to our attention. It was also very strange why only the xyz aircraft were being deiced and none of the other acrs.

Title: FLC INSPECTED ACFT AND DETERMINED IT WAS ICE FREE, SO DIDN'T DEICE PRIOR TO DEP. AN ACI DETERMINED OTHERWISE AND FAULTED FLC FOR NOT DEICING.

Narrative: WE LANDED IN MCI ON A FLT FROM SLC DEC/XX/96. ON THIS APCH OR DSCNT WE PENETRATED A THIN LAYER OF CLOUDS WITH LIGHT ICE. WE USED ENG ANTI-ICE AND ONLY HAD A SLIGHT ICE INDICATION. WE TAXIED INTO THE GATE AT MCI. ANOTHER OF OUR XYZ ACFT WAS BEING DEICED. ALL XYZ RAMP SPACES HAD DEICE FLUID ON IT. AFTER THE ENGS WERE SHUT DOWN I RECEIVED A CHOCKS SIGNAL AND RELEASED THE BRAKES. THE ACFT MOVED AND BRAKES WERE INSTANTLY REAPPLIED. I WENT OUTSIDE AND FOUND THE DEICING FLUID ON THE RAMP CAUSED THE CHOCKS TO SLIP. THE SO WAS BRIEFED TO CHK FOR ICE ON HIS WALKAROUND. I THEN WENT TO EXIT ROW 20 AND 22 AND CHKED OVER THE WING TOPS ON BOTH SIDES OF THE ACFT. THE WINGS WERE CLEAN OF ALL ICE. THE SO RPTED THAT HIS WALKAROUND SHOWED THE ACFT CLEAN. THE FO AND I CHKED THE FRONT OF THE ACFT FROM THE GATE HOUSE, AND THE ACFT APPEARED CLEAN. I THEN MADE A CAPT'S DECISION THAT WE DID NOT NEED DEICING FOR FLT XX TO ATL FROM MCI. FAA MAINT INSPECTOR CAME UP THE AFT AIRSTAIR UNANNOUNCED. WE CHALLENGED HIS IDENT WHEN HE CAME TO THE COCKPIT. HE WAS FROM THE FAA TO INSPECT MAINT. I TOLD HIM TO GO AHEAD. JUST PRIOR TO PUSH BACK FOR FLT, ONE OF OUR GND CREW CAME TO THE COCKPIT AND ASKED WHEN DO WE WANT TO BE DEICED. WE TOLD HIM THAT THE ACFT WAS CHKED AND DID NOT NEED DEICING. WHEN WE PUSHED FLT XX BACK FROM THE GATE FAA INSPECTOR PULLED HIS CAR IN FRONT OF THE JETWAY AND WATCHED US START ENGS AND LEAVE. LATER I LEARNED AFTER I FLEW AN UNEVENTFUL FLT TO ATLANTA, THAT THE FAA INSPECTOR WANTED ALL GND CREW AND FLC NAMES AND HE WAS FURIOUS WE DID NOT DEICE. I AS THE CAPT MADE A REASONABLE AND EXTRA CHKS THAT THIS ACFT DID NOT NEED DEICING. IT WAS IN CLR DRY AIR AND OVER 10 MI VISIBILITY. IF THIS INSPECTOR FOR THE FAA THOUGHT WE WERE UNSAFE HE SHOULD HAVE PREVENTED THE TKOF. OTHERWISE HE WAS JUST TRYING TO SET US UP, BUT IF HE NOTICED SOMETHING THAT I OR MY CREW DID NOT HE SHOULD HAVE BROUGHT IT TO OUR ATTN. IT WAS ALSO VERY STRANGE WHY ONLY THE XYZ ACFT WERE BEING DEICED AND NONE OF THE OTHER ACRS.
