APCH CTLR FORGOT TO NOTIFY FLC AT RADAR FIX ON INST APCH.

Narrative

THIS WAS AN IFR TRAINING FLT TO TERMINATE AT RNT. WX WAS ABOUT 2500 FT BROKEN; SCATTERED RAIN. VISIBILITY LOWER TO N. NDB-15 IS A RADAR APCH; REQUIRING SEATTLE APCH TO CALL THE FINAL APCH FIX; HAKIM. WE WERE AT 2100 FT; CLRED TO TRACK FINAL APCH COURSE INBOUND; CTLR SAID HE WOULD CALL HAKIM. STUDENT THOUGHT WE HADN'T HEARD FROM APCH FOR A LONG TIME; SO HE CALLED APCH WITH A REMINDER. CTLR APOLOGIZED; SAYING WE WERE 2 MI INSIDE HAKIM AND WE SHOULD GO TO TWR. (VISUALLY WE WERE MORE LIKE 3 MI INSIDE; STILL AT 2000 FT). THIS LOCATION REQUIRED THE STUDENT TO GO VISUAL AND FULL RUDDER SIDESLIP TO MAKE THE RWY - AT NIGHT WITH REDUCED VISIBILITY. NOT THE BEST TRAINING SIT. ONCE ON THE RWY; THERE WAS SIGNIFICANT STANDING WATER AND THE ASPHALT WAS SLICK. IN ADDITION; THE PAINT LINES ON THE RWY WERE DIFFICULT TO SEE; NECESSITATING A LONG ROLL-OUT. TWR HAD CLRED A C-210 TO LAND BEHIND US AND SINCE WE WERE SLOW TO EXIT; ISSUED A GAR TO THE 210. OTHER PLT RPTED THAT HE WAS STOL AND COULD WAIT TILL WE WERE CLR. ON EXITING THE RWY; LOOKING BACK SAW THE 210 JUST A COUPLE OF FT ABOVE THE RWY. NOTHING REALLY UNSAFE HAPPENED; BUT THE AIRSPACE INCURSION AND UNUSUAL MANEUVERING ON THE PART OF BOTH AIRPLANES WAS PRECIPITATED BY THE CTLR'S FORGETTING TO CALL HAKIM. THIS AT AN ARPT WHERE PLTS HAVE BEEN VIOLATED RECENTLY FOR FORGETTING TO RPT BEFORE ENTERING CLASS D AIRSPACE.
