## Analysis

DURING LANDING ROLLOUT ON RUNWAY 19R DIRECTIONAL CONTROL WAS LOST WITH THE AIRCRAFT VERRING TO THE RIGHT OF THE RUNWAY. CORRECTION WAS MADE TO THE LEFT, BUT THE AIRCRAFT VEERED OFF THE RUNWAY TO THE LEFT. THE WIND WAS FROM 160 AT 9. THE DENSITY ALTITUDE WAS ABOUT 5200 FEET. THE PILOT WAS CAUTIONED ABOUT WAKE TURBULENCE DUE TO DEPARTING HEAVY JET TRAFFIC. THE AIRCRAFT PORBABLY ENCOUNTERED WAKE TURBULENCE DURING THE LANDING ROLL.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Loss of control - on ground/water, landing - roll
  - weather condition - high density altitude (contributing factor)
  - proper touchdown point - not attained, pilot in command (cause)
  - lack of total experience in type of aircraft, pilot in command (cause)
  - directional control - not maintained, pilot in command (cause)
  - design stress limits of aircraft - uncontrolled, pilot in command (cause)
- On ground/water encounter with terrain/water, landing - roll

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
