Narrative:

On arrival from the south, cleared to intercept dxo 239 degree radial, cross mizar intersection at 12000 ft. Misread STAR, used DME off crl, not dxo. Missed crossing by 2000 ft. I was preoccupied by the #3 engine EPR gauge. Just had #3 engine replaced in atl. Engine indications were not consistent with a normal operating engine. We were involved in figuring out why. Turns out the EPR gauge was bad. When we were asked by ATC if we were going to make mizar at 12000 ft, I still didn't realize what had happened until after we were on approach in dtw. Also, we usually get a clearance to intercept the crl 246 degree radial to mizar, not the dxo 239 degree radial.

Original NASA ASRS Text

Title: LGT MISSES XING RESTR ON ARR.

Narrative: ON ARR FROM THE S, CLRED TO INTERCEPT DXO 239 DEG RADIAL, CROSS MIZAR INTXN AT 12000 FT. MISREAD STAR, USED DME OFF CRL, NOT DXO. MISSED XING BY 2000 FT. I WAS PREOCCUPIED BY THE #3 ENG EPR GAUGE. JUST HAD #3 ENG REPLACED IN ATL. ENG INDICATIONS WERE NOT CONSISTENT WITH A NORMAL OPERATING ENG. WE WERE INVOLVED IN FIGURING OUT WHY. TURNS OUT THE EPR GAUGE WAS BAD. WHEN WE WERE ASKED BY ATC IF WE WERE GOING TO MAKE MIZAR AT 12000 FT, I STILL DIDN'T REALIZE WHAT HAD HAPPENED UNTIL AFTER WE WERE ON APCH IN DTW. ALSO, WE USUALLY GET A CLRNC TO INTERCEPT THE CRL 246 DEG RADIAL TO MIZAR, NOT THE DXO 239 DEG RADIAL.
