Narrative:

Airplane arrived at gate in den after making approach, missed approach and subsequent approach to a landing in reported (actual) moderate icing conditions. Inbound captain advised the airplane should be checked thoroughly for ice. I did the walkaround and first noticed the gate deice in progress on the landing gear and belly. Walking under the wings I noticed the entire underskin of the wing, and the flap drive fairings were coated in a rough rime approximately 1/4 inch thick. The wing leading edges were clean. I also noted that the inbound crew had retracted the flaps. The tail had up to 1-2 inches of rime on the leading edges. After return to the cockpit I called the deice coordinator to determine who would deice the underside of the wings. (I advised the gate deicer had left) he said he would call the gate deicer to return to complete the job. At pushback, I asked the mechanic if the wings looked clean, and he said they were, but that the #1 engine fan, inlet probes and left leading edge flap were still coated with ice. I called the deice coordinator a third time to have the job completed properly. I believe the gate deicer was seriously jeopardizing flight safety with poor attention to his duty. Flight and deice crews need more information on who is responsible for deicing what parts of the airplane. I also believe the push mechanic helped avert a potentially serious takeoff incident.

Title: B737-300 CAPT COMPLAINT THAT THE GND CREW DEICING PERSONNEL TOOK 3 TIMES TO COMPLETELY AND ADEQUATELY DEICE THE ACFT PRIOR TO FLT DUE TO COMPLACENCY.

Narrative: AIRPLANE ARRIVED AT GATE IN DEN AFTER MAKING APCH, MISSED APCH AND SUBSEQUENT APCH TO A LNDG IN RPTED (ACTUAL) MODERATE ICING CONDITIONS. INBOUND CAPT ADVISED THE AIRPLANE SHOULD BE CHKED THOROUGHLY FOR ICE. I DID THE WALKAROUND AND FIRST NOTICED THE GATE DEICE IN PROGRESS ON THE LNDG GEAR AND BELLY. WALKING UNDER THE WINGS I NOTICED THE ENTIRE UNDERSKIN OF THE WING, AND THE FLAP DRIVE FAIRINGS WERE COATED IN A ROUGH RIME APPROX 1/4 INCH THICK. THE WING LEADING EDGES WERE CLEAN. I ALSO NOTED THAT THE INBOUND CREW HAD RETRACTED THE FLAPS. THE TAIL HAD UP TO 1-2 INCHES OF RIME ON THE LEADING EDGES. AFTER RETURN TO THE COCKPIT I CALLED THE DEICE COORDINATOR TO DETERMINE WHO WOULD DEICE THE UNDERSIDE OF THE WINGS. (I ADVISED THE GATE DEICER HAD LEFT) HE SAID HE WOULD CALL THE GATE DEICER TO RETURN TO COMPLETE THE JOB. AT PUSHBACK, I ASKED THE MECH IF THE WINGS LOOKED CLEAN, AND HE SAID THEY WERE, BUT THAT THE #1 ENG FAN, INLET PROBES AND L LEADING EDGE FLAP WERE STILL COATED WITH ICE. I CALLED THE DEICE COORDINATOR A THIRD TIME TO HAVE THE JOB COMPLETED PROPERLY. I BELIEVE THE GATE DEICER WAS SERIOUSLY JEOPARDIZING FLT SAFETY WITH POOR ATTN TO HIS DUTY. FLT AND DEICE CREWS NEED MORE INFO ON WHO IS RESPONSIBLE FOR DEICING WHAT PARTS OF THE AIRPLANE. I ALSO BELIEVE THE PUSH MECH HELPED AVERT A POTENTIALLY SERIOUS TKOF INCIDENT.
