Narrative:

On mar/wed/95, I was the captain on flight from den to mtj. The WX in montrose was IMC. There was a departure out of mtj, so we were told to hold as published over the montrose VOR. I requested to fly out to the 14.8 DME arc for the ILS DME runway 17 approach and hold over bruuk (the final approach fix), if the aircraft wasn't clear by the time we got there. We were at 16000 ft. When we were established on the 14.8 DME arc, we were cleared for the runway 17 DME ILS at mtj. The arc was fairly short and the minimum altitude on the arc was 9500 ft. Once we were established on the localizer, we were still well above the GS and intercept altitude. We descended in an attempt to become established on the GS, but the approach wasn't stabilized so I went missed approach. I continued on the localizer course and established a straight ahead climb. I don't remember the altitude at which we started the missed approach, but it was well above the decision ht. I asked the first officer to read to me the missed approach instructions and altitude. The procedure was to hold as published at 8500 ft over the mtj VOR. We were at an altitude at this point well above 8500 ft. We told center we were missed approach and they asked us of our intentions. We requested another ILS runway 17 DME approach for which we were then cleared. I shot this approach and landed at mtj. The reason I believe we flew through the 8500 ft missed approach altitude was because we weren't very far below that altitude when the approach was missed. I did have the missed approach instructions memorized, but not the altitude. The first thing that came to mind on the missed approach was to start climbing and clean the aircraft up. Also, I didn't think the missed altitude was below the initial approach altitude.

Narrative: ON MAR/WED/95, I WAS THE CAPT ON FLT FROM DEN TO MTJ. THE WX IN MONTROSE WAS IMC. THERE WAS A DEP OUT OF MTJ, SO WE WERE TOLD TO HOLD AS PUBLISHED OVER THE MONTROSE VOR. I REQUESTED TO FLY OUT TO THE 14.8 DME ARC FOR THE ILS DME RWY 17 APCH AND HOLD OVER BRUUK (THE FINAL APCH FIX), IF THE ACFT WASN'T CLR BY THE TIME WE GOT THERE. WE WERE AT 16000 FT. WHEN WE WERE ESTABLISHED ON THE 14.8 DME ARC, WE WERE CLRED FOR THE RWY 17 DME ILS AT MTJ. THE ARC WAS FAIRLY SHORT AND THE MINIMUM ALT ON THE ARC WAS 9500 FT. ONCE WE WERE ESTABLISHED ON THE LOC, WE WERE STILL WELL ABOVE THE GS AND INTERCEPT ALT. WE DSNDED IN AN ATTEMPT TO BECOME ESTABLISHED ON THE GS, BUT THE APCH WASN'T STABILIZED SO I WENT MISSED APCH. I CONTINUED ON THE LOC COURSE AND ESTABLISHED A STRAIGHT AHEAD CLB. I DON'T REMEMBER THE ALT AT WHICH WE STARTED THE MISSED APCH, BUT IT WAS WELL ABOVE THE DECISION HT. I ASKED THE FO TO READ TO ME THE MISSED APCH INSTRUCTIONS AND ALT. THE PROC WAS TO HOLD AS PUBLISHED AT 8500 FT OVER THE MTJ VOR. WE WERE AT AN ALT AT THIS POINT WELL ABOVE 8500 FT. WE TOLD CTR WE WERE MISSED APCH AND THEY ASKED US OF OUR INTENTIONS. WE REQUESTED ANOTHER ILS RWY 17 DME APCH FOR WHICH WE WERE THEN CLRED. I SHOT THIS APCH AND LANDED AT MTJ. THE REASON I BELIEVE WE FLEW THROUGH THE 8500 FT MISSED APCH ALT WAS BECAUSE WE WEREN'T VERY FAR BELOW THAT ALT WHEN THE APCH WAS MISSED. I DID HAVE THE MISSED APCH INSTRUCTIONS MEMORIZED, BUT NOT THE ALT. THE FIRST THING THAT CAME TO MIND ON THE MISSED APCH WAS TO START CLBING AND CLEAN THE ACFT UP. ALSO, I DIDN'T THINK THE MISSED ALT WAS BELOW THE INITIAL APCH ALT.
