The reporter had set the altimeter wrong by 1 inch. On climbing east from apa on an IFR flight plan in VMC he checked in with departure and gave an altitude of 8600 ft. Approach informed him they showed him at 9600 ft and stated the altimeter setting. The reporter reset the correct altimeter setting in and descended back to 9000 ft, the assigned altitude.

Narrative:

I had set the altimeter off 1 inch barometric pressure from actual on run-up. Climbing east out of apa on an IFR flight plan on an assigned heading, I checked on with departure and gave an altitude climbing through for 9000 ft. On climbing through 8600 ft approach informed me they showed me at 9600 ft and gave me the barometric reading. Seeing I had the wrong setting I reset the altimeter and descended to the assigned altitude. Error in setting my altimeter and in approach not catching error in altitude when I checked onto the frequency. Prevention is in not being so complacent since it was such a nice clear day and approach verifying, checking on altitude.

Title: THE RPTR HAD SET THE ALTIMETER WRONG BY 1 INCH. ON CLBING E FROM APA ON AN IFR FLT PLAN IN VMC HE CHKED IN WITH DEP AND GAVE AN ALT OF 8600 FT. APCH INFORMED HIM THEY SHOWED HIM AT 9600 FT AND STATED THE ALTIMETER SETTING. THE RPTR RESET THE CORRECT ALTIMETER SETTING IN AND DSNDED BACK TO 9000 FT, THE ASSIGNED ALT.

Narrative: I HAD SET THE ALTIMETER OFF 1 INCH BAROMETRIC PRESSURE FROM ACTUAL ON RUN-UP. CLBING E OUT OF APA ON AN IFR FLT PLAN ON AN ASSIGNED HDG, I CHKED ON WITH DEP AND GAVE AN ALT CLBING THROUGH FOR 9000 FT. ON CLBING THROUGH 8600 FT APCH INFORMED ME THEY SHOWED ME AT 9600 FT AND GAVE ME THE BAROMETRIC READING. SEEING I HAD THE WRONG SETTING I RESET THE ALTIMETER AND DSNDED TO THE ASSIGNED ALT. ERROR IN SETTING MY ALTIMETER AND IN APCH NOT CATCHING ERROR IN ALT WHEN I CHKED ONTO THE FREQ. PREVENTION IS IN NOT BEING SO COMPLACENT SINCE IT WAS SUCH A NICE CLR DAY AND APCH VERIFYING, CHKING ON ALT.
