## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

TCAS RESOLUTION ADVISORY (RA) AND LOSS OF SEPARATION DUE TO TCAS CLIMB COMMAND. N56RB, A VFR MO20, WAS SOUTHEAST BOUND AT AN ASSIGNED ALTITUDE OF 3,500 FEET. SWA367, A B-737, WAS SOUTH BOUND AT 4,000 FEET. SWA367 WAS ISSUED TRAFFIC AND REPORTED N56RB IN SIGHT. THE MODE C FOR N56RB WAS INDICATING 3,600 FEET. SWA367 RECEIVED A TCAS ALERT ON N56RB AND CLIMBED TO 4,300 FEET. TRAFFIC WAS AAL81, A B-777, WHICH WAS PASSING ABOVE AND IN FRONT OF SWA367 AT 5,000 FEET. AS SWA367 CLIMBED, HE ENTERED THE WAKE REMNANT FROM AAL81, RESULTING IN A LOSS OF SEPARATION. CLOSEST PROXIMITY WAS 0.73 LATERAL AND 800 FEET VERTICAL.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record.
