The pilots rushed to land as soon as possible, leading to errors in judgment that included the crew's failure to complete the airline's pre-landing checklist before landing. 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. The flight crew also failed to set landing flaps, another item on the pre-flight checklist, but as the plane descended past , the first officer realized the flaps were not set and the flight crew set a 40-degree flap setting for landing.
