C172 TRAINEE PLT ON SOLO XCOUNTRY HAD RWY INCURSION AT MLU.

Narrative

ON JUN/XA/00 ONE OF MY STUDENT PLTS WAS ENDORSED FOR A SOLO TRAINING XCOUNTRY FLT. HE COMPLETED HIS PREFLT AND WAS INSTRUCTED TO TAXI OUT TO RWY 18 VIA TXWY G. HE TURNED ONTO TXWY B FROM TXWY G INSTEAD OF CONTINUING THE TURN ON TXWY G TO TXWY A. AT TXWY B; HE BECAME CONFUSED BECAUSE HE SAW 2 MANDATORY SIGNS SIDE-BY-SIDE -- RWY 14/32 BEING THE FIRST AND RWY 18/36 BEING THE SECOND. HE SAID HE THOUGHT HE WOULD BE XING RWY 14/32 INSTEAD OF RWY 18/36 TO GET TO RWY 18. THIS IS THE POINT WHERE THE INCURSION OCCURRED. THE TIME OF OCCURRENCE WAS XA09Z. THE CONFUSION WAS THAT YOU NORMALLY CROSS RWY 14 AT TXWY A TO GET TO RWY 18. HE DID NOT REALIZE THAT AT TXWY B; BOTH RWYS INTERSECT. AFTER HE RETURNED AND I LEARNED OF HIS MISTAKE; HE WAS GIVEN ADDITIONAL INSTRUCTION CONCERNING RWY INCURSIONS. I PROVIDED HIM WITH ADDITIONAL TRAINING MATERIAL TO INCLUDE A PAMPHLET ON REDUCING RWY INCURSIONS; A FLYER ON RWY INCURSIONS COMMONSENSE GUIDELINES; AND A REFERRAL TO THE COMMERCIAL CHART PVT PLT TRAINING MANUAL PAGES 4-29. ADDITIONAL TRAINING WAS SCHEDULED TO INCLUDE A TRIP TO THE ATC FACILITY FOR ADDITIONAL TRAINING. ADDITIONAL GND AND FLT INSTRUCTION WILL ALSO BE GIVEN TO MAKE SURE THE STUDENT UNDERSTANDS ALL THE RWY MARKINGS.
