Narrative:

Air carrier X takeoff roll at mob, at approximately 60 KTS noticed an aircraft (2 engine civic) approaching the runway from A5 taxiway. He taxied onto the runway directly in our path. Executed a rejected takeoff at approximately 70 KTS. Aircraft stopped approximately 50-100 from cpr Y. Maintenance had to change the #4 tire on the aircraft (B727). Telephone call to the tower operator at the time of the incident revealed that 'Y' was cleared to runway 14 via taxiway 'a.' he missed the turn onto 'a' and continued straight ahead on 'A5' taxiway and entered runway 14/32 during our takeoff roll. The problem arose primarily through inadequate airport familiarization and taxiing too fast on the part of the king air pilot. Contributing factor could have been taxiway markings and tower operator not monitoring his taxi progress. Incursion was first discovered by so. It would have been discovered later in a 2-MAN cockpit! Correction action -- more careful taxiing. Better lighting for taxiway with vivid markings prior to runway.

Original NASA ASRS Text

Title: CPR Y RWY EXCURSION HAD LTSS FROM ACR X. ABORTED TKOF.

Narrative: ACR X TKOF ROLL AT MOB, AT APPROX 60 KTS NOTICED AN ACFT (2 ENG CIVIC) APCHING THE RWY FROM A5 TXWY. HE TAXIED ONTO THE RWY DIRECTLY IN OUR PATH. EXECUTED A REJECTED TKOF AT APPROX 70 KTS. ACFT STOPPED APPROX 50-100 FROM CPR Y. MAINT HAD TO CHANGE THE #4 TIRE ON THE ACFT (B727). TELEPHONE CALL TO THE TWR OPERATOR AT THE TIME OF THE INCIDENT REVEALED THAT 'Y' WAS CLRED TO RWY 14 VIA TXWY 'A.' HE MISSED THE TURN ONTO 'A' AND CONTINUED STRAIGHT AHEAD ON 'A5' TXWY AND ENTERED RWY 14/32 DURING OUR TKOF ROLL. THE PROB AROSE PRIMARILY THROUGH INADEQUATE ARPT FAMILIARIZATION AND TAXIING TOO FAST ON THE PART OF THE KING AIR PLT. CONTRIBUTING FACTOR COULD HAVE BEEN TXWY MARKINGS AND TWR OPERATOR NOT MONITORING HIS TAXI PROGRESS. INCURSION WAS FIRST DISCOVERED BY SO. IT WOULD HAVE BEEN DISCOVERED LATER IN A 2-MAN COCKPIT! CORRECTION ACTION -- MORE CAREFUL TAXIING. BETTER LIGHTING FOR TXWY WITH VIVID MARKINGS PRIOR TO RWY.
