Narrative:

I was captain on small transport and departed the brw. At approximately 150-200' MSL the control yoke was pulled out of my hand and pinned against the panel. At that time I was at takeoff power and climbing at 90 KTS. The aircraft pitched up abruptly approximately 60 degrees nose up attitude and entered the stall buffet. I was able to keep the wings level with rudder and reduced power and the nose pitched down abruptly to approximately 30 degrees nose down attitude. I again added power to approximately 30# of torque and the aircraft pitched up again and entered the stall buffet. At this point I brought the power off slowly to approximately 15# of torque and with very minute adjustment of the trim I was able to stabilize in a 250 FPM climb at vysc 76 KTS. The first officer had already advised FSS at brw that we had lost elevator control and were probably going down. I climbed to 2500' MSL and entered a left downwind for runway 24 at brw. I experimented with trim (elevator) and power settings for a landing attitude. When FSS advised that crash fire rescue equipment crews in place, I turned a 5.5 DME final for 24 and began descending, the approach required approximately 30 degree crab, due to winds from the southeast at 17 KTS. I was able to make a successful landing with no damage or injuries to the 7 passenger. The maintenance department found the elevator bell crank support broken on both sides. NTSB was notified by brw FSS. First officer notified FSS of loss of elevator control and declared emergency landed.

Title: ACFT SUFFERED LOSS OF ELEVATOR CONTROL ON TKOF.

Narrative: I WAS CAPT ON SMT AND DEPARTED THE BRW. AT APPROX 150-200' MSL THE CTL YOKE WAS PULLED OUT OF MY HAND AND PINNED AGAINST THE PANEL. AT THAT TIME I WAS AT TKOF PWR AND CLBING AT 90 KTS. THE ACFT PITCHED UP ABRUPTLY APPROX 60 DEGS NOSE UP ATTITUDE AND ENTERED THE STALL BUFFET. I WAS ABLE TO KEEP THE WINGS LEVEL WITH RUDDER AND REDUCED PWR AND THE NOSE PITCHED DOWN ABRUPTLY TO APPROX 30 DEGS NOSE DOWN ATTITUDE. I AGAIN ADDED PWR TO APPROX 30# OF TORQUE AND THE ACFT PITCHED UP AGAIN AND ENTERED THE STALL BUFFET. AT THIS POINT I BROUGHT THE PWR OFF SLOWLY TO APPROX 15# OF TORQUE AND WITH VERY MINUTE ADJUSTMENT OF THE TRIM I WAS ABLE TO STABILIZE IN A 250 FPM CLB AT VYSC 76 KTS. THE F/O HAD ALREADY ADVISED FSS AT BRW THAT WE HAD LOST ELEVATOR CONTROL AND WERE PROBABLY GOING DOWN. I CLBED TO 2500' MSL AND ENTERED A LEFT DOWNWIND FOR RWY 24 AT BRW. I EXPERIMENTED WITH TRIM (ELEVATOR) AND PWR SETTINGS FOR A LNDG ATTITUDE. WHEN FSS ADVISED THAT CFR CREWS IN PLACE, I TURNED A 5.5 DME FINAL FOR 24 AND BEGAN DSNDING, THE APCH REQUIRED APPROX 30 DEG CRAB, DUE TO WINDS FROM THE SE AT 17 KTS. I WAS ABLE TO MAKE A SUCCESSFUL LNDG WITH NO DAMAGE OR INJURIES TO THE 7 PAX. THE MAINT DEPT FOUND THE ELEVATOR BELL CRANK SUPPORT BROKEN ON BOTH SIDES. NTSB WAS NOTIFIED BY BRW FSS. F/O NOTIFIED FSS OF LOSS OF ELEVATOR CTL AND DECLARED EMER LANDED.
