The flight was making a departure from RWY 29 after the operational hours for both the runway in question and PWN control tower.
The only runway active at the time of the flight’s departure was RWY 18/36.
Flight crew continued with the departure procedure on RWY 29 and carried out the scheduled WN4805 service to Baltimore/Washington International Thurgood Marshall Airport (BWI).
The flight then landed at the destination airport without further incident.
The FAA subsequently reported that an airport service vehicle had exited the deactivated departure runway at PWM just before the Southwest flight took off.
In a statement issued after the departure incident, the FAA said: “Southwest Airlines Flight 4805 departed from a temporarily closed runway at the Portland International Jetport on Tuesday, June 25.”
“An airport vehicle exited the runway before the plane began its takeoff roll. The FAA and NTSB are investigating the event, which occurred around 5:45 a.m. local time.”
