Southwest Airlines Flight 31 Nashville TN Plane Crash

Incident report:

• Date: December 15, 2015
• Location: Nashville, Tennessee, United States
• Airline: Southwest Airlines
• Type of Aircraft: Boeing 737




• Type of Incident: Taxiway
• Total Passengers: 133
• Injuries: 8
• Fatalities: 0

On December 15, 2015, a Boeing 737 operated by Southwest Airlines exited a paved taxiway surface while approaching the gate at Nashville International Airport. The aircraft came to rest in the grass adjacent to the taxiway. Several occupants reported injuries, and the aircraft was subsequently evacuated.

Events occurring during taxi and gate-approach phases fall within the broader framework of aviation accident litigation, where analysis frequently focuses on ground movement procedures, surface condition, braking performance, and airport layout.

Ground Operations and Surface Movement

Taxiway excursions differ materially from runway takeoff or landing accidents. During low-speed surface operations, investigators typically evaluate:

• taxi routing and clearance instructions
• aircraft speed during gate approach
• surface conditions and pavement integrity
• lighting and signage
• braking system performance
• crew workload and situational awareness

In commercial airline operations, gate sequencing may require directional adjustments while transitioning from taxiway to apron areas. Even at reduced speeds, lateral deviation from paved surfaces can result in structural damage or passenger injury.

Aircraft Systems and Structural Considerations

In taxiway excursion events involving transport-category aircraft such as the Boeing 737, examination often includes landing gear integrity, steering mechanisms, braking system function, and potential subsurface conditions that may contribute to pavement failure or directional deviation.

When injuries occur during ground movement events, investigation typically includes documentation of aircraft configuration, deceleration forces, cabin conditions, and evacuation procedures.

Regulatory Investigation

The Federal Aviation Administration and, where applicable, the National Transportation Safety Board review operational and technical aspects of such events. Investigative processes may include crew interviews, review of airport surface surveillance data, examination of aircraft maintenance records, and analysis of airport infrastructure.

The structure and stages of federal aviation investigations are explained in the firm’s overview of the NTSB Investigation Process.

Commercial Airline Ground Event Risk

Although ground-movement events are generally lower energy than in-flight accidents, they present distinct operational and infrastructure-related considerations. Evaluation of causation requires integration of crew procedure, airport design, aircraft systems, and environmental conditions rather than reliance on a single explanatory factor.
