Narrative:

I was acting as flight instructor on a local VFR training flight. Our aircraft (cessna 310) was cleared for takeoff on runway 16L at fort worth meacham field. We took the usual amount of time to taxi onto, line up, and apply takeoff power. The airplane was accelerating through 80 mph when the tower advised us to 'abort takeoff -- aircraft on runway!' as we heard this we saw a cessna 152 crossing ahead about 500-800 ft from left to right. An abort was not possible -- we rotated slightly early and passed over the top and slightly left of the cessna 152. Tower called us about a min later and advised us that the cessna 152 was operated by a student pilot whose instructor would be called. My student was practicing a maximum performance takeoff which allowed us to become airborne sooner than usual. If we had performed a normal takeoff the near miss would have possibly been much closer. After talking to another instructor who was listening to ground control I learned more information. The C-152 pilot was told to taxi to runway 16L (no crossing intersection). ATIS was calling runway 16L closed (work is being done to the lighting system but can be opened for large aircraft). Runway 16L was temporarily open for lunch. C-52 pilot may have thought runway 16L was closed and was taxiing to runway 16R on the intersection from which the incursion occurred. C-152 pilot inquired about which runway to use -- and may have misunderstood the ground controller. C-152 ple was told to stop repeatedly by ground control before incursion occurred. C-152 pilot crossed the entire runway. Contributing factor -- the student was solo and had likely used runway 16R for the majority of training -- ATIS also advertised runway 16 left as 'closed,' this has been the usual at meacham for the past 10 weeks. The solo student likely speaks english as a second language.

Title: STUDENT PLT INADVERTENTLY TAXIED ACROSS ACTIVE RWY IN FRONT OF ANOTHER ACFT TAKING OFF, CAUSING A NMAC.

Narrative: I WAS ACTING AS FLT INSTRUCTOR ON A LCL VFR TRAINING FLT. OUR ACFT (CESSNA 310) WAS CLRED FOR TKOF ON RWY 16L AT FORT WORTH MEACHAM FIELD. WE TOOK THE USUAL AMOUNT OF TIME TO TAXI ONTO, LINE UP, AND APPLY TKOF PWR. THE AIRPLANE WAS ACCELERATING THROUGH 80 MPH WHEN THE TWR ADVISED US TO 'ABORT TKOF -- ACFT ON RWY!' AS WE HEARD THIS WE SAW A CESSNA 152 XING AHEAD ABOUT 500-800 FT FROM L TO R. AN ABORT WAS NOT POSSIBLE -- WE ROTATED SLIGHTLY EARLY AND PASSED OVER THE TOP AND SLIGHTLY L OF THE CESSNA 152. TWR CALLED US ABOUT A MIN LATER AND ADVISED US THAT THE CESSNA 152 WAS OPERATED BY A STUDENT PLT WHOSE INSTRUCTOR WOULD BE CALLED. MY STUDENT WAS PRACTICING A MAX PERFORMANCE TKOF WHICH ALLOWED US TO BECOME AIRBORNE SOONER THAN USUAL. IF WE HAD PERFORMED A NORMAL TKOF THE NEAR MISS WOULD HAVE POSSIBLY BEEN MUCH CLOSER. AFTER TALKING TO ANOTHER INSTRUCTOR WHO WAS LISTENING TO GND CTL I LEARNED MORE INFO. THE C-152 PLT WAS TOLD TO TAXI TO RWY 16L (NO CROSSING INTXN). ATIS WAS CALLING RWY 16L CLOSED (WORK IS BEING DONE TO THE LIGHTING SYS BUT CAN BE OPENED FOR LARGE ACFT). RWY 16L WAS TEMPORARILY OPEN FOR LUNCH. C-52 PLT MAY HAVE THOUGHT RWY 16L WAS CLOSED AND WAS TAXIING TO RWY 16R ON THE INTXN FROM WHICH THE INCURSION OCCURRED. C-152 PLT INQUIRED ABOUT WHICH RWY TO USE -- AND MAY HAVE MISUNDERSTOOD THE GND CTLR. C-152 PLE WAS TOLD TO STOP REPEATEDLY BY GND CTL BEFORE INCURSION OCCURRED. C-152 PLT CROSSED THE ENTIRE RWY. CONTRIBUTING FACTOR -- THE STUDENT WAS SOLO AND HAD LIKELY USED RWY 16R FOR THE MAJORITY OF TRAINING -- ATIS ALSO ADVERTISED RWY 16 L AS 'CLOSED,' THIS HAS BEEN THE USUAL AT MEACHAM FOR THE PAST 10 WEEKS. THE SOLO STUDENT LIKELY SPEAKS ENGLISH AS A SECOND LANGUAGE.
