Narrative:

On sep/xa/98 at approximately XX30, my student and I were preparing to take off from las airport on our way back to fmn. We had just performed our runup and were cleared for takeoff from runway 19R. My student was at the flight controls and taxied us onto the runway. He taxied us onto the runway via green taxiway centerline lighting that was on the displaced threshold of the runway. Since there was taxiway centerline lighting to lead us onto the runway, I assumed there would be runway centerline lighting. In addition, runway 19L is not far from the runway we were on and parallel to our runway. My student lined us up with what we thought was the centerline for runway 19R because of the taxiway centerline lighting and the edge lights from runway 19L. He began to accelerate the aircraft and at some point I realized that we were not aligned with the centerline but instead the edge lights. I instructed my student to abort the takeoff, but we hit 2 lights. In hitting the lights we bent one of the propeller blades. The presence of taxiway centerline lighting but no runway centerline lighting and the proximity of the parallel runway made the illusion that we were, in fact, on the centerline.

Title: DURING DUAL TRAINING FLT IN A BEECH A36, THE TRAINEE INADVERTENTLY LINED UP WITH THE RWY EDGE LIGHTING FOR TKOF RESULTING IN HITTING 2 LIGHTS BEFORE ABORTING TKOF. THE 2 RWY LIGHTS AND THE ACFT PROP WERE DAMAGED.

Narrative: ON SEP/XA/98 AT APPROX XX30, MY STUDENT AND I WERE PREPARING TO TAKE OFF FROM LAS ARPT ON OUR WAY BACK TO FMN. WE HAD JUST PERFORMED OUR RUNUP AND WERE CLRED FOR TKOF FROM RWY 19R. MY STUDENT WAS AT THE FLT CTLS AND TAXIED US ONTO THE RWY. HE TAXIED US ONTO THE RWY VIA GREEN TXWY CTRLINE LIGHTING THAT WAS ON THE DISPLACED THRESHOLD OF THE RWY. SINCE THERE WAS TXWY CTRLINE LIGHTING TO LEAD US ONTO THE RWY, I ASSUMED THERE WOULD BE RWY CTRLINE LIGHTING. IN ADDITION, RWY 19L IS NOT FAR FROM THE RWY WE WERE ON AND PARALLEL TO OUR RWY. MY STUDENT LINED US UP WITH WHAT WE THOUGHT WAS THE CTRLINE FOR RWY 19R BECAUSE OF THE TXWY CTRLINE LIGHTING AND THE EDGE LIGHTS FROM RWY 19L. HE BEGAN TO ACCELERATE THE ACFT AND AT SOME POINT I REALIZED THAT WE WERE NOT ALIGNED WITH THE CTRLINE BUT INSTEAD THE EDGE LIGHTS. I INSTRUCTED MY STUDENT TO ABORT THE TKOF, BUT WE HIT 2 LIGHTS. IN HITTING THE LIGHTS WE BENT ONE OF THE PROP BLADES. THE PRESENCE OF TXWY CTRLINE LIGHTING BUT NO RWY CTRLINE LIGHTING AND THE PROX OF THE PARALLEL RWY MADE THE ILLUSION THAT WE WERE, IN FACT, ON THE CTRLINE.
