## Probable cause

THE PILOT'S FAILURE TO FOLLOW WAKE TURBULENCE AVOIDANCE PROCEDURES.

## Sequence of events

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

- Vortex turbulence encountered, landing - roll
  - procedures/directives - not followed, pilot in command (cause)
  - wake turbulence - encountered, pilot in command (cause)
- Loss of control - on ground/water, landing - roll
- Main gear collapsed, landing - roll

## Analysis

THE PILOT REPORTED THAT HE LANDED CLOSELY BEHIND A DEPARTING BOEING 757 AND SUBSEQUENTLY LOST DIRECTIONAL CONTROL. HE SAID THAT HE HAD BEEN CAUTIONED BY THE TOWER ABOUT THE POTENTIAL FOR WAKE TURBULENCE, BUT ELECTED TO LAND ANYWAY. HE ALSO REPORTED THAT HE SHOULD HAVE ABORTED HIS LANDING.
