Narrative:

I was on climb out from missed approach at tnu on a radar vector to ILS runway 13L dsm. I had selected the altitude but failed to push the preselect arm button on the flight director, so when I was occupied with getting ready for the next approach, I allowed the aircraft to fly through the assigned altitude. A faster xchk would have eliminated the error. Callback conversation with reporter revealed the following information: reporter stated this was training flight with check pilot on board. Reporter was performing emergency procedure at time of altitude deviation and was distracted. Workload was very high.

Original NASA ASRS Text

Title: ALTDEV ALT OVERSHOT IN MISSED APCH PROC.

Narrative: I WAS ON CLBOUT FROM MISSED APCH AT TNU ON A RADAR VECTOR TO ILS RWY 13L DSM. I HAD SELECTED THE ALT BUT FAILED TO PUSH THE PRESELECT ARM BUTTON ON THE FLT DIRECTOR, SO WHEN I WAS OCCUPIED WITH GETTING READY FOR THE NEXT APCH, I ALLOWED THE ACFT TO FLY THROUGH THE ASSIGNED ALT. A FASTER XCHK WOULD HAVE ELIMINATED THE ERROR. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATED THIS WAS TRAINING FLT WITH CHK PLT ON BOARD. RPTR WAS PERFORMING EMER PROC AT TIME OF ALTDEV AND WAS DISTRACTED. WORKLOAD WAS VERY HIGH.
