Narrative:

During the takeoff from runway 16L at vr; I attempted to rotate the aircraft and had no response. I continued pulling the yoke all the way back to the stop. I told the captain; 'I got nothing; the nose won't come up.' then we aborted; and notified the tower. After clearing the runway; instructed the passenger to remain seated; check the brake cooling; and requested the ground control to send someone to check our brakes and tires. A truck came out. He told the ground controller that he saw nothing unusual. We stopped; without setting the brakes; contacted the company and requested a gate and maintenance to meet the aircraft. Callback conversation with reporter revealed the following information: the first officer; the PF; advised that after return to the gate; maintenance discovered metal protruding below the stabilizer. Comments from maintenance technicians at the scene indicated a failure in the boost panel mechanism between the horizontal stabilizer and the elevator. Reporter speculates that the protruding metal was some part of the hydraulic actuator mechanism that failed; allowing full aft stick deployment without producing actual elevator displacement. He had no information regarding actual maintenance action.

Title: B737-300 FAILS TO ROTATE FOR TKOF DESPITE FULL UP ELEVATOR COMMAND BY THE PF. TKOF ABORTED 20 KTS ABOVE PLANNED VR.

Narrative: DURING THE TKOF FROM RWY 16L AT VR; I ATTEMPTED TO ROTATE THE ACFT AND HAD NO RESPONSE. I CONTINUED PULLING THE YOKE ALL THE WAY BACK TO THE STOP. I TOLD THE CAPT; 'I GOT NOTHING; THE NOSE WON'T COME UP.' THEN WE ABORTED; AND NOTIFIED THE TWR. AFTER CLRING THE RWY; INSTRUCTED THE PAX TO REMAIN SEATED; CHK THE BRAKE COOLING; AND REQUESTED THE GND CTL TO SEND SOMEONE TO CHK OUR BRAKES AND TIRES. A TRUCK CAME OUT. HE TOLD THE GND CTLR THAT HE SAW NOTHING UNUSUAL. WE STOPPED; WITHOUT SETTING THE BRAKES; CONTACTED THE COMPANY AND REQUESTED A GATE AND MAINT TO MEET THE ACFT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE FO; THE PF; ADVISED THAT AFTER RETURN TO THE GATE; MAINT DISCOVERED METAL PROTRUDING BELOW THE STABILIZER. COMMENTS FROM MAINT TECHNICIANS AT THE SCENE INDICATED A FAILURE IN THE BOOST PANEL MECHANISM BTWN THE HORIZ STABILIZER AND THE ELEVATOR. RPTR SPECULATES THAT THE PROTRUDING METAL WAS SOME PART OF THE HYD ACTUATOR MECHANISM THAT FAILED; ALLOWING FULL AFT STICK DEPLOYMENT WITHOUT PRODUCING ACTUAL ELEVATOR DISPLACEMENT. HE HAD NO INFO REGARDING ACTUAL MAINT ACTION.
