NTSB narrative
On November 20, 2014, about 2000 central standard time, Southwest Airlines flight 8751, a Boeing 737-700, registration N263WN, collided with Southwest Airlines flight 301, a Boeing 737-800. N263WN was a functional check flight operating under the provisions of 14 CFR Part 91 with two flight crew members onboard. N8314L was a scheduled domestic passenger flight operating under the provisions of 14 CFR Part 121with 177 passengers and crew members onboard. There were no injuries to the occupants of either airplane.
According to flight crew statements, N8314L had landed on runway 13L and was holding on taxi lane P, with parking brakes set, because gate 14 was occupied.
N263WN pushed off from gate 3 and was cleared to taxi to runway 13L via taxiway B. As the flight approached taxi lane P, the first officer stated "watch the 800." The captain steered the airplane to the right of centerline of taxiway B, and believed his wingtip was clear of the left-hand horizontal stabilizer of N8314L. The captain said he then shifted his attention back to the airplane's taxi path to avoid over-correcting to the right of centerline; however, their left hand wingtip struck the parked N8314L's right hand horizontal stabilizer. N263WN's left hand wingtip received minor damage and N8314L's right hand horizontal stabilizer was substantially damaged.
Probable cause
N263WN captain's failure to maintain a safe clearance from the parked N8314L resulting in a ground collision.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2014-11-21.
