The pilot had requested the longest runway which was runway 10. ATC then ordered the airport maintenance ground crew that was doing runway maintenance work on runway 10 to clear their maintenance vehicles of the runway. The maintenance crew attempted to move their vehicles but did not have enough time.  On a two mile final approach Flight 497 was cleared for runway 19. ATC gave Flight 497 their last instructions, cleared to land. ATC then informed the emergency fire equipment crew that they were cleared onto the runway after Flight 497 had landed.  

Upon landing, the crew experienced a loss of anti-skid braking and nose-wheel steering, and exited the runway approximately 2,000 feet from the approach threshold. The passengers and crew exited the airplane via slides. It was reported that the right forward slide did not inflate. There were no reported injuries. Initial information indicates the Airbus 320-232 encountered minor damage. However, the NTSB will be examining the aircraft. 

Dan Bower an NTSB technical expert in systems and survival factors has been signed to lead the NTSB investigation. Additional NTSB experts in the areas of operations, maintenance records, vehicle performance, and flight recorders will also assist.
