Narrative:

This incident occurred during a flight requalification evaluate I was administering to a previously qualified jetstream captain. We had completed 2 of the stall maneuvers required of the check and were involved in the 'takeoff/departure' stall event. This event calls for takeoff flap setting of 10 degrees, torque set at 30%. The nose is raised to 20 degrees pitch and the bank is increased to 20 degrees. Normally the aircraft stall warning and recovery occurs within 300 ft of maneuver initiation. In this case the examinee set the torque at 40% and slowly pulled the pitch to 20 degrees. This resulted in a greater increase of altitude than normally experienced. I asked him to reduce the power and about the same time received a call from ZMP asking us to verify our altitude. I noticed it about 8400 ft MSL and relayed that to the center. We were in VFR conditions and had not noticed any aircraft in our area, though when center advised of the deviation, we detected another above and at least 2 mi distant. We had the TCASII on and received no warning. We immediately descended back to the cleared IFR altitude of 8000 ft and I was provided a telephone number and advised to call that number upon landing. Center advised they were preparing a 'deviation incident report.' this incident was caused by my failure to request a 'block' altitude from ZMP prior to initiating the maneuver which I knew might result in a 300 ft climb. Why didn't I? The examinee had so perfectly executed the previous stall recovery maneuvers, I suspected he would complete this one within 250 ft. I was also working ZMP rather than an approach facility, which I normally do on check rides, and suspected he would complete the maneuver without going 'out of the altitude parameters.' to prevent a future occurrence, I will forever obtain a 'block altitude' prior to initiating any stall maneuver in controled airspace. Supplemental information for acn 587187: I did it according to company policy and in the process gained approximately 400 ft which is normal for this maneuver. I immediately recovered from the approaching stall and descended down to 8000 ft. We were only above 8300 ft for a few seconds. During the descent ATC called out nearby traffic which we picked up visually. The other aircraft, at 9000 ft and approximately 2 mi away, also stated that had us in sight.

Title: A BA3100 FLT CREW ON A FLT EVALUATION, EXCEEDS ASSIGNED ALT BY 400 FT.

Narrative: THIS INCIDENT OCCURRED DURING A FLT REQUALIFICATION EVAL I WAS ADMINISTERING TO A PREVIOUSLY QUALIFIED JETSTREAM CAPT. WE HAD COMPLETED 2 OF THE STALL MANEUVERS REQUIRED OF THE CHK AND WERE INVOLVED IN THE 'TKOF/DEP' STALL EVENT. THIS EVENT CALLS FOR TKOF FLAP SETTING OF 10 DEGS, TORQUE SET AT 30%. THE NOSE IS RAISED TO 20 DEGS PITCH AND THE BANK IS INCREASED TO 20 DEGS. NORMALLY THE ACFT STALL WARNING AND RECOVERY OCCURS WITHIN 300 FT OF MANEUVER INITIATION. IN THIS CASE THE EXAMINEE SET THE TORQUE AT 40% AND SLOWLY PULLED THE PITCH TO 20 DEGS. THIS RESULTED IN A GREATER INCREASE OF ALT THAN NORMALLY EXPERIENCED. I ASKED HIM TO REDUCE THE PWR AND ABOUT THE SAME TIME RECEIVED A CALL FROM ZMP ASKING US TO VERIFY OUR ALT. I NOTICED IT ABOUT 8400 FT MSL AND RELAYED THAT TO THE CTR. WE WERE IN VFR CONDITIONS AND HAD NOT NOTICED ANY ACFT IN OUR AREA, THOUGH WHEN CTR ADVISED OF THE DEV, WE DETECTED ANOTHER ABOVE AND AT LEAST 2 MI DISTANT. WE HAD THE TCASII ON AND RECEIVED NO WARNING. WE IMMEDIATELY DSNDED BACK TO THE CLRED IFR ALT OF 8000 FT AND I WAS PROVIDED A TELEPHONE NUMBER AND ADVISED TO CALL THAT NUMBER UPON LNDG. CTR ADVISED THEY WERE PREPARING A 'DEV INCIDENT RPT.' THIS INCIDENT WAS CAUSED BY MY FAILURE TO REQUEST A 'BLOCK' ALT FROM ZMP PRIOR TO INITIATING THE MANEUVER WHICH I KNEW MIGHT RESULT IN A 300 FT CLB. WHY DIDN'T I? THE EXAMINEE HAD SO PERFECTLY EXECUTED THE PREVIOUS STALL RECOVERY MANEUVERS, I SUSPECTED HE WOULD COMPLETE THIS ONE WITHIN 250 FT. I WAS ALSO WORKING ZMP RATHER THAN AN APCH FACILITY, WHICH I NORMALLY DO ON CHK RIDES, AND SUSPECTED HE WOULD COMPLETE THE MANEUVER WITHOUT GOING 'OUT OF THE ALT PARAMETERS.' TO PREVENT A FUTURE OCCURRENCE, I WILL FOREVER OBTAIN A 'BLOCK ALT' PRIOR TO INITIATING ANY STALL MANEUVER IN CTLED AIRSPACE. SUPPLEMENTAL INFO FOR ACN 587187: I DID IT ACCORDING TO COMPANY POLICY AND IN THE PROCESS GAINED APPROX 400 FT WHICH IS NORMAL FOR THIS MANEUVER. I IMMEDIATELY RECOVERED FROM THE APCHING STALL AND DSNDED DOWN TO 8000 FT. WE WERE ONLY ABOVE 8300 FT FOR A FEW SECONDS. DURING THE DSCNT ATC CALLED OUT NEARBY TFC WHICH WE PICKED UP VISUALLY. THE OTHER ACFT, AT 9000 FT AND APPROX 2 MI AWAY, ALSO STATED THAT HAD US IN SIGHT.
