On November 11, 2017, about 1230 Pacific standard time, Southwest Airlines flight 1159, a Boeing 737-700, N740SW, had a provisioning agent fall from the airplane while parked at Gate 13 at Los Angeles International Airport (KLAX), Los Angeles, California . The flight was deplaning and onboard were the captain, first officer, three flight attendants, several passengers, and the provisioning agent. The regularly scheduled passenger flight was operating under the provisions of 14 Code of Federal Regulations Part 121 from San Francisco International Airport (KSFO), San Francisco, California, to KLAX.

According to the operator, the provisioning vans platform/box assembly malfunctioned and lowered about 2-3 feet. As the provisioning agent was moving from the airplane to the platform he lost situational awareness and fell onto the lowered platform, injuring his shoulder. The agent was transported to the hospital and diagnosed with a fractured right shoulder. The van was removed from service and the left side tape switch was found to have dislodged from its track, resulting in the uncommanded lowering of the platform.
