Narrative:

Being cleared for takeoff on 8L, power levers were advised before brake release. Aircraft veered right on runway. We aborted and cleared the runway. All engine indications appeared normal. We thought it had been jet blast from an aircraft holding short on the parallel runway, so we elected to takeoff again. This time we pulled on runway in a position where jet blast wouldn't affect us. Once again power levers were advanced and we felt the same right turn. We then realized there was a mechanical problem and taxied back to the gate.

Title: COMMUTER LTT FLT CREW REJECTS TKOF AT DEN DUE YAW AT POWER APPLICATION.

Narrative: BEING CLRED FOR TKOF ON 8L, PWR LEVERS WERE ADVISED BEFORE BRAKE RELEASE. ACFT VEERED RIGHT ON RWY. WE ABORTED AND CLRED THE RWY. ALL ENG INDICATIONS APPEARED NORMAL. WE THOUGHT IT HAD BEEN JET BLAST FROM AN ACFT HOLDING SHORT ON THE PARALLEL RWY, SO WE ELECTED TO TKOF AGAIN. THIS TIME WE PULLED ON RWY IN A POS WHERE JET BLAST WOULDN'T AFFECT US. ONCE AGAIN PWR LEVERS WERE ADVANCED AND WE FELT THE SAME RIGHT TURN. WE THEN REALIZED THERE WAS A MECHANICAL PROB AND TAXIED BACK TO THE GATE.
