At approximately 2136 central time, a Boeing 737-300 struck runway lights during a loss of control on landing on runway 04 at the Amarillo International Airport. The five crewmembers and 63 passengers were not injured. During the instrument approach into the field, the crew reported being on the edge of a thunderstorm and said visibility was starting to deteriorate. Just before landing, the controller reported the wind from 220 at 9 knots. The airplane touched down with no perceptible drift, but then veered to the left side of the runway. The airplanes nose gear collapsed aft into the forward navigation/electronics bay, damaging the fuselage and the pressure bulkhead.
