Narrative:

After a normal preflight and runup, I picked up ATIS information. As I received altimeter setting, I set the kollsman window to what I thought was the correct altimeter setting. During the previous day a frontal passage had resulted in a significant change in pressure. When I adjusted the altimeter to reflect the current barometric pressure, I turned it to the nearest number to end in .33. This resulted in my setting 29.33 when 30.33 was the proper setting. Following an uneventful taxi and takeoff, I was cleared on a 360 degree vector up to 5000 ft MSL. Due to my improper kollsman window setting, I leveled at 6000 ft MSL although my altimeter indicated 5000 ft MSL. Mke departure questioned my requesting altitude. I responded 5000 ft. Departure stated they showed me level 6000 ft. I requested a current altimeter setting. After receiving a 30.33 (approximately) setting, the problem was located. At this point, I made ATC aware of my mistake, and descended to 5000 ft MSL. I apologized and was advised no problem existed. One note: when handed off from tower to departure, I checked in 1100 ft MSL (approximately) climbing 5000 ft MSL right turn 360 degrees. This passing altitude was actually 2100 ft MSL and was not noted by mke departure. In retrospect, I believe this situation resulted from complacency. I had flown this scheduled route many times before and on a clear night was very comfortable with it. I think this relaxed atmosphere in conjunction with a lack of attention to detail was cause of my climbing through the assigned altitude.

Original NASA ASRS Text

Title: A BEECH 99 FREIGHTER PLT CLBS 1000 FT ABOVE HIS ASSIGNED CRUISE ALT WHEN HE SETS HIS ALTIMETER TO A SETTING THAT IS 1 INCH TOO LOW. ALTIMETER READS 5000 FT WHEN HE LEVELS AT 6000 FT 10 MI N OF MKE, WI.

Narrative: AFTER A NORMAL PREFLT AND RUNUP, I PICKED UP ATIS INFO. AS I RECEIVED ALTIMETER SETTING, I SET THE KOLLSMAN WINDOW TO WHAT I THOUGHT WAS THE CORRECT ALTIMETER SETTING. DURING THE PREVIOUS DAY A FRONTAL PASSAGE HAD RESULTED IN A SIGNIFICANT CHANGE IN PRESSURE. WHEN I ADJUSTED THE ALTIMETER TO REFLECT THE CURRENT BAROMETRIC PRESSURE, I TURNED IT TO THE NEAREST NUMBER TO END IN .33. THIS RESULTED IN MY SETTING 29.33 WHEN 30.33 WAS THE PROPER SETTING. FOLLOWING AN UNEVENTFUL TAXI AND TKOF, I WAS CLRED ON A 360 DEG VECTOR UP TO 5000 FT MSL. DUE TO MY IMPROPER KOLLSMAN WINDOW SETTING, I LEVELED AT 6000 FT MSL ALTHOUGH MY ALTIMETER INDICATED 5000 FT MSL. MKE DEP QUESTIONED MY REQUESTING ALT. I RESPONDED 5000 FT. DEP STATED THEY SHOWED ME LEVEL 6000 FT. I REQUESTED A CURRENT ALTIMETER SETTING. AFTER RECEIVING A 30.33 (APPROX) SETTING, THE PROB WAS LOCATED. AT THIS POINT, I MADE ATC AWARE OF MY MISTAKE, AND DSNDED TO 5000 FT MSL. I APOLOGIZED AND WAS ADVISED NO PROB EXISTED. ONE NOTE: WHEN HANDED OFF FROM TWR TO DEP, I CHKED IN 1100 FT MSL (APPROX) CLBING 5000 FT MSL R TURN 360 DEGS. THIS PASSING ALT WAS ACTUALLY 2100 FT MSL AND WAS NOT NOTED BY MKE DEP. IN RETROSPECT, I BELIEVE THIS SIT RESULTED FROM COMPLACENCY. I HAD FLOWN THIS SCHEDULED RTE MANY TIMES BEFORE AND ON A CLR NIGHT WAS VERY COMFORTABLE WITH IT. I THINK THIS RELAXED ATMOSPHERE IN CONJUNCTION WITH A LACK OF ATTN TO DETAIL WAS CAUSE OF MY CLBING THROUGH THE ASSIGNED ALT.

A beech 99 freighter pilot climbs 1000 ft above his assigned cruise altitude when he sets his altimeter to a setting that is 1 inch too low. Altimeter reads 5000 ft when he levels at 6000 ft 10 mi north of mke, wi.
