NTSB narrative
The captain reported that during a descent in IMC conditions, the traffic collision avoidance system (TCAS) sounded "traffic, traffic, traffic." The TCAS displayed a target 700 feet below, and 15 miles ahead of the flight. However, the TCAS did not issue a resolution advisory. The flight crew could not visually identify the traffic, and the captain instructed the first officer to stop the descent. The first officer disconnected the autopilot and then "quickly" leveled the airplane. During the level off, a flight attendant fell and suffered a fractured leg. Subsequently, a review of the TCAS and check with ATC revealed that the traffic was at FL 260, not FL 270. A review of the airline's operations manual revealed that deviation from an ATC clearance was authorized for a resolution advisory.
Probable cause
The first officer's abrupt level off.

- 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: investigation status, coordinates, damage. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
