## 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
  - proper climb rate - exceeded, pilot in command (contributing factor)
  - airspeed - not maintained, pilot in command (cause)
  - stall - inadvertent, pilot in command (cause)
- In flight collision with object, descent - uncontrolled
  - object - tree(s) (contributing factor)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

SHORTLY AFTER TAKEOFF, WITNESSES OBSERVED THE ACFT IN A STEEP CLIMB. RPRTDLY, IT THEN ENTERED A LEFT TURN & APPEARED TO STALL. THE PLT STATED THAT AFTER ABOUT 180 DEG OF TURN, HE ROLLED OUT, NOSE LOW, LEVELED THE WINGS, THEN A VIBRATION STARTED. RPRTDLY, THE ACFT BEGAN TO SHAKE AS IF IT WERE IN AN ACCELLERATED STALL. THE PLT PUSHED THE YOKE FORWARD TO BREAK THE STALL, BUT THE ACFT SUBSEQUENTLY HIT TREES & CRASHED TO THE GND. THE PLT SUSPECTED THE VIBRATION MIGHT HAVE BEEN FM SOMETHING OTHER THAN A STALL; HOWEVER, NO PREIMPACT PART FAILURE OR MALFUNCTION WAS FND.
