Narrative:

We were shooting the ILS runway 9 into fnt, mi, in actual IMC. All was normal except I (as captain) omitted joining the first officer (PF) on the localizer frequency when we were cleared for the ILS. Consequently the autoplt (we were performing a monitored approach) was not tracking normally. I commanded first officer to disengage, then re-engage autoplt. We had not discovered my frequency selection error so I requested a turn off the localizer to go back and shoot the ILS runway 9 again. We were outside the marker at 3000 ft and when accepting a heading of 180 degrees the autoplt pitched up briefly. I believe we might have gained 300-400 ft before returning to 3000 ft. We proceeded further outbound and shot an uneventful monitored ILS runway 9 at fnt, mi. Supplemental information from acn 328749: aircraft overshot final heading by 30 degrees. While trying to get autoplt to accept automatic approach mode, autoplt started a climb. So called airspeed when he saw 15 KTS slow. I added power then noted aircraft in climb. First officer distracted trying to couple approach mode and attempt to correct altitude deviation with autoplt too long. Concerned with low WX minimums, all night flying, tired, all 3 crew members new in seat position.

Title: FO WAS UNABLE TO SELECT AUTO APCH MODE FOR A MONITORED ILS APCH. WHILE TRYING TO GET THE AUTOPLT TO ACCEPT, THE AUTOPLT OVERSHOT FINAL AND STARTED A CLB. FLC REQUESTED ANOTHER APCH AND THEN DISCOVERED THAT THE CAPT'S SIDE WAS STILL SET TO A VOR FREQ.

Narrative: WE WERE SHOOTING THE ILS RWY 9 INTO FNT, MI, IN ACTUAL IMC. ALL WAS NORMAL EXCEPT I (AS CAPT) OMITTED JOINING THE FO (PF) ON THE LOC FREQ WHEN WE WERE CLRED FOR THE ILS. CONSEQUENTLY THE AUTOPLT (WE WERE PERFORMING A MONITORED APCH) WAS NOT TRACKING NORMALLY. I COMMANDED FO TO DISENGAGE, THEN RE-ENGAGE AUTOPLT. WE HAD NOT DISCOVERED MY FREQ SELECTION ERROR SO I REQUESTED A TURN OFF THE LOC TO GO BACK AND SHOOT THE ILS RWY 9 AGAIN. WE WERE OUTSIDE THE MARKER AT 3000 FT AND WHEN ACCEPTING A HDG OF 180 DEGS THE AUTOPLT PITCHED UP BRIEFLY. I BELIEVE WE MIGHT HAVE GAINED 300-400 FT BEFORE RETURNING TO 3000 FT. WE PROCEEDED FURTHER OUTBOUND AND SHOT AN UNEVENTFUL MONITORED ILS RWY 9 AT FNT, MI. SUPPLEMENTAL INFO FROM ACN 328749: ACFT OVERSHOT FINAL HDG BY 30 DEGS. WHILE TRYING TO GET AUTOPLT TO ACCEPT AUTO APCH MODE, AUTOPLT STARTED A CLB. SO CALLED AIRSPD WHEN HE SAW 15 KTS SLOW. I ADDED PWR THEN NOTED ACFT IN CLB. FO DISTRACTED TRYING TO COUPLE APCH MODE AND ATTEMPT TO CORRECT ALTDEV WITH AUTOPLT TOO LONG. CONCERNED WITH LOW WX MINIMUMS, ALL NIGHT FLYING, TIRED, ALL 3 CREW MEMBERS NEW IN SEAT POS.
