Narrative:

Stl departure cleared us to 6000. I was PIC, in right seat. The ceo of the company I fly for was flying the aircraft from the left seat. (He is rated as a private pilot sel). I am a CFI mei. We had been flying together that day for 9 hours. We were having a discussion on where to get a rent-a-car at our destination in wichita. The controller said: say altitude! We had passed 6000 on our way to 7000. The problem was that I had too much confidence in my student's ability (he has been flying more years than I). Also, he insisted on flying the plane by hand instead of autoplt. The autoplt has an altitude preselect and warning system which I always use, to remind me of the newly assigned altitudes. I believe a combination of 1) fatigue, 9 hours flying at this point and 18 hours duty time, with 2 hours still to go (there is no flying time duty regulations for part 91 corporate flying). 2) having too much confidence in my student's ability (he screwed up, but I didn't catch it). This was an entire flight crew problem. What I have learned is that it is good practice for sterile environment on the flight deck until cruise has been reached.

Title: CORPORATE LIGHT TWIN ENGINE ACFT OVERSHOOTS ASSIGNED ALT ON CLIMB. THE CHIEF EXECUTIVE OFFICER IS FLYING THE ACFT FROM THE LEFT SEAT, WHILE THE PLT IN COMMAND IS MONITORING FROM THE RIGHT SEAT.

Narrative: STL DEP CLRED US TO 6000. I WAS PIC, IN RIGHT SEAT. THE CEO OF THE COMPANY I FLY FOR WAS FLYING THE ACFT FROM THE LEFT SEAT. (HE IS RATED AS A PRIVATE PLT SEL). I AM A CFI MEI. WE HAD BEEN FLYING TOGETHER THAT DAY FOR 9 HRS. WE WERE HAVING A DISCUSSION ON WHERE TO GET A RENT-A-CAR AT OUR DEST IN WICHITA. THE CTLR SAID: SAY ALT! WE HAD PASSED 6000 ON OUR WAY TO 7000. THE PROBLEM WAS THAT I HAD TOO MUCH CONFIDENCE IN MY STUDENT'S ABILITY (HE HAS BEEN FLYING MORE YEARS THAN I). ALSO, HE INSISTED ON FLYING THE PLANE BY HAND INSTEAD OF AUTOPLT. THE AUTOPLT HAS AN ALT PRESELECT AND WARNING SYSTEM WHICH I ALWAYS USE, TO REMIND ME OF THE NEWLY ASSIGNED ALTS. I BELIEVE A COMBINATION OF 1) FATIGUE, 9 HRS FLYING AT THIS POINT AND 18 HRS DUTY TIME, WITH 2 HRS STILL TO GO (THERE IS NO FLYING TIME DUTY REGS FOR PART 91 CORPORATE FLYING). 2) HAVING TOO MUCH CONFIDENCE IN MY STUDENT'S ABILITY (HE SCREWED UP, BUT I DIDN'T CATCH IT). THIS WAS AN ENTIRE FLT CREW PROBLEM. WHAT I HAVE LEARNED IS THAT IT IS GOOD PRACTICE FOR STERILE ENVIRONMENT ON THE FLT DECK UNTIL CRUISE HAS BEEN REACHED.
