## Probable cause

FAILURE OF THE PILOT TO OBTAIN OR MAINTAIN SUFFICIENT AIRSPEED, WHICH RESULTED IN AN INADVERTENT STALL.

## 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
  - airspeed - not attained, pilot in command (cause)
  - stall - inadvertent, pilot in command (cause)
- In flight collision with terrain/water, takeoff

## Analysis

THE PILOT STATED THAT AFTER LIFT-OFF, THE PLANE 'WENT UP TOO RAPIDLY CAUSING A STALL.'  HE PUSHED THE YOKE FOREWARD & THE AIRPLANE CAME DOWN HARD, WHICH RESULTED IN DAMAGE TO THE NOSE GEAR & FIREALL.
