Narrative:
On climb out from rdu, following blue devil one departure on 290 degree right cleared to 3000'. Was distraction and let first officer climb to 3500' before I noticed overshoot. Immediately descended back to 3000' and continued departure. Departure didn't say anything, and did not question us about our altitude. During critical phase off I should pay more attention to the job at hand. Lucky there were no inbnds to rdu. We were talking about the takeoff. The stall warning came on at about 100'. The light transport has this problem and it is a recurring problem. Has something to so with airflow over the stall vane, adjustment is critical. Supplemental information from acn 150317. Captain and I were discussing my takeoff since the stall warning activated at 100' AGL momentarily. While a critique was necessary, we should have waited until we were above 10000' MSL. This was a good reminder of the importance of the 'sterile cockpit'.

Title: ALT DEVIATION IS EXPERIENCED BY LTT FLT CREW AS THEY ARE DISTR BY PREVIOUS ACTIVATION OF STALL WARNING EQUIPMENT.
Narrative: ON CLB OUT FROM RDU, FOLLOWING BLUE DEVIL ONE DEP ON 290 DEG R CLRED TO 3000'. WAS DISTR AND LET F/O CLB TO 3500' BEFORE I NOTICED OVERSHOOT. IMMEDIATELY DSNDED BACK TO 3000' AND CONTINUED DEP. DEP DIDN'T SAY ANYTHING, AND DID NOT QUESTION US ABOUT OUR ALT. DURING CRITICAL PHASE OFF I SHOULD PAY MORE ATTN TO THE JOB AT HAND. LUCKY THERE WERE NO INBNDS TO RDU. WE WERE TALKING ABOUT THE TKOF. THE STALL WARNING CAME ON AT ABOUT 100'. THE LTT HAS THIS PROB AND IT IS A RECURRING PROB. HAS SOMETHING TO SO WITH AIRFLOW OVER THE STALL VANE, ADJUSTMENT IS CRITICAL. SUPPLEMENTAL INFO FROM ACN 150317. CAPT AND I WERE DISCUSSING MY TKOF SINCE THE STALL WARNING ACTIVATED AT 100' AGL MOMENTARILY. WHILE A CRITIQUE WAS NECESSARY, WE SHOULD HAVE WAITED UNTIL WE WERE ABOVE 10000' MSL. THIS WAS A GOOD REMINDER OF THE IMPORTANCE OF THE 'STERILE COCKPIT'.
