## Probable cause

THE PILOT'S FAILURE TO MAINTAIN ADEQUATE SEPARATION BEHIND A DEPARTING LARGER AIRCRAFT RESULTED IN TURBULENCE ENCOUNTER & SUBSEQUENT LOSS OF CONTROL.

## Sequence of events

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

- Loss of control - in flight, takeoff - initial climb
  - distance - not maintained, pilot in command (cause)
  - wake turbulence - encountered, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled
  - terrain condition - runway

## Analysis

THE PILOT DEPARTED RUNWAY 22, IMMEDIATELY FOLLOWING A LARGER AIRPLANE. THE AIRCRAFT ROLLED INVERTED AND IMPACTED THE RUNWAY IN A STEEP NOSE DOWN ATTIUTDE.  WITNESSES STATED THAT THEY SAW ITS 'WINGS ROCKING' JUST BEFORE THE ACCIDENT. THE FAA FOUND NO FLIGHT CONTROL MALFUNCTIONS.
