NTSB investigators used data provided by various sources and may not have traveled in support of this investigation to prepare this aircraft incident report.

THE AIRPLANE WAS CLEARED FOR TAKEOFF ON RUNWAY 12R, BUT A TAKEOFF WAS MADE ON RUNWAY 17. THE SOUTH 2,200 FEET OF RUNWAY 17 WAS CLOSED DUE TO CONSTRUCTION. THIS WAS NOTED BY NOTAMS AND ATIS AND THE CREWMEMBERS WERE AWARE OF IT. AS THE AIRPLANE ROTATED, THE LOWER PARTS OF IT IMPACTED SECTIONS OF WOODED BARRIERS THAT HAD BEEN PLACED ACROSS RUNWAY 17. THE CREW WAS IMFORMED OF POSSIBLE DAMAGE AND PROCEEDED TO DESTINATION WHERE EMERGENCY EQUIPMENT WAS WAITING AT LANDING. AIRPLANE DAMAGE WAS MINOR. SEVENTY THREE DAYS PRIOR TO THIS INCIDENT, ANOTHER AIR CARRIER AIRPLANE WAS CLEARED FOR TAKEOFF ON RUNWAY 12R AND ALSO INADVERTENTLY DEPARTED ON RUNWAY 17.

The National Transportation Safety Board determines the probable cause(s) of this incident to be:

CREW'S FAILURE TO FOLLOW TAXI INSTRUCTIONS AND TO INSURE THAT THEY WERE ON THE PROPER RUNWAY PRIOR TO INITIATION OF THE TAKEOFF ROLL.
