BUR CTLR DESCRIBED INCIDENT WHEN AN ACFT TAXIING IN FAILED TO REMAIN ON TAXI LINE CAUSING RWY INCURSION WITH ACFT DEPARTING.

Narrative

ACFT X; AN MD82 WAS INSTRUCTED TO TAXI TO THE GATE; REMAIN ON TWR FREQ. ACFT Y WAS SUBSEQUENTLY CLRED FOR TKOF ON A XING RWY THAT THE MD82 HAD LANDED ON AND EXITED. ACFT X MADE A WIDE R TURN FROM THE TAXI LINE TO FACILITATE AN EASIER L TURN INTO THE GATE. THAT R TURN CAUSED THE MD82 TO ENCROACH UPON THE RWY. AFTER INSTRUCTING THE MD82 TO TURN AWAY FROM THE RWY I LOOKED BACK TO CHK THE EXACT LOCATION OF THE DEP. THE DEP WAS ALREADY AIRBORNE APPROX MIDFIELD. AT BURBANK ARPT; THE TERMINAL IS IN CLOSE PROX TO THE RWY ENVIRONMENT; AND OPERATES UNDER A WAIVER DUE THE TERMINAL BEING LESS THAN STANDARD DISTANCE FROM THE RWY ENVIRONMENT. THE TAXI LINE IN THE TXWY A TERMINAL AREA IS DESIGNED TO KEEP ACFT UNDER 118 FT WINGSPAN AWAY FROM THE RWY SAFETY AREA. THE TAXI LINE IN THE TXWY B AREA IS RESTR TO 113 FT WINGSPAN. THE MD82 IS 112 FT GIVING LESS THAN A 1 FT LEEWAY FROM THE WINGTIP TO THE RWY SAFETY AREA. THE RWY SAFETY AREA LINE IS 50 FT FROM THE RWY EDGE. THE MD82 WAS CTRED ON THE RWY SAFETY LINE PLACING ITS WINGTIP OVER THE RWY EDGE LINE. BECAUSE OF THE LIMITED SPACE IN THE TERMINAL AREA IT IS IMPORTANT FOR ALL ACFT TO REMAIN ON THE TAXI LINES UNLESS OTHERWISE INSTRUCTED.
