Flight 1420 was scheduled to depart DFW at 20:28 (8:28 pm)
Central Daylight Time, and arrive in Little Rock at 21:41 (9:41 pm). The pilots were advised before boarding that the departure would be delayed, and that the
National Weather Service had issued in-flight weather advisories indicating severe
thunderstorms along the planned flight path. Adverse weather caused the plane that was intended for Flight 1420 to be delayed in arriving at DFW. Airline policy set a maximum pilot duty time of 14 hours, and Flight 1420 was the flight crew's last flight of the day. The first officer notified the airline's flight dispatcher that the flight crew would, therefore, be unable to depart after 23:16 (11:16 pm). The airline substituted another MD-80, tail number N215AA, which allowed Flight 1420 to depart DFW at 22:40 (10:40 pm). At 23:04 (11:04 pm),
air traffic controllers issued a weather advisory indicating severe thunderstorms in an area that included the Little Rock airport, and the flight crew witnessed lightning while on approach. The flight crew discussed the weather reports, but decided to expedite the approach rather than diverting to the designated alternate airport (
Nashville International Airport) or returning to DFW. Air traffic control at Little Rock had originally told Flight 1420 to expect an approach to runway 22L. At 23:39 (11:39 pm), a controller advised the crew of a wind-shear alert and a change in wind direction. As a result, Captain Buschmann requested a change to Runway 4R, so the flight would have a headwind during landing, and Flight 1420 was cleared for a visual approach to this runway. Because the plane was already close to the airport, the controller had to direct it away to line it up for a landing on 4R. As a result, Flight 1420 faced away from the airport for several minutes, and due to the plane's weather radar capabilities being limited to a narrow and forward-facing field of view, the flight crew could not see thunderstorms approaching the airport during their turn. As the aircraft approached, a severe thunderstorm arrived over the airport, and at 23:44 (11:44 pm), the first officer notified the controller that the crew had lost sight of the runway. The controller then cleared the aircraft to land on 4R using an
instrument landing system (ILS) approach. The pilots rushed to land as soon as possible, leading to errors in judgment that included the crew's failure to complete the MD-82's pre-landing checklist before descending. This was a crucial event in the
accident chain, as the crew overlooked multiple critical landing systems on the checklist. The flight crew failed to arm the automatic
spoiler system, which automatically moves the spoiler control lever, and deploys the spoilers upon landing. The pilots also failed to set the plane's
automatic braking system. Furthermore, the pilots failed to set the
landing flaps, another item on the before landing checklist, but as the plane descended past , the first officer realized the flaps were not set, and the flight crew set the flaps at 40° setting for landing. At 23:49:32 (11:49:32 pm), the controller issued the last weather report before Flight 1420 landed, and advised that winds at the airport were 330° at . The reported winds exceeded the MD-82's
crosswind limit for landing in reduced visibility on a wet runway. Despite the excessive crosswind and two wind-shear reports, Captain Buschmann did not abandon the aircraft's approach into Little Rock, deciding to continue the approach to 4R instead. ==Accident==
