An air carrier aircraft cleared for takeoff on runway 12R inadvertently departed on runway 17, where the south 2,200 feet were closed due to construction. During rotation, the airplane struck wooden barriers placed across the runway, causing minor damage.

Incident Overview

An air carrier aircraft was cleared for takeoff on runway 12R but instead executed a takeoff on runway 17. The south 2,200 feet of runway 17 were closed due to construction activities, a fact that was communicated via NOTAMs and ATIS broadcasts. The crewmembers were aware of the closure. As the airplane rotated during takeoff, the lower portions of the aircraft impacted sections of wooden barriers that had been placed across runway 17 to demarcate the closed area.

Aftermath

After the impact, the crew was informed of possible damage to the aircraft. They continued to their intended destination, where emergency equipment was standing by upon landing. Inspection revealed that the airplane sustained minor damage.

Previous Similar Event

Seventy-three days prior to this incident, another air carrier aircraft had been cleared for takeoff on runway 12R and also inadvertently departed on runway 17.
