## Probable cause

THE PILOT-IN-COMMAND'S FAILURE TO OBTAIN A PROPER CLIMB RATE.

## 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 - not obtained, pilot in command (cause)
  - stall/mush - inadvertent, pilot in command (contributing factor)
- In flight collision with terrain/water, landing - flare/touchdown
  - precautionary landing - performed, pilot in command
  - terrain condition - rough/uneven
  - unsuitable terrain or takeoff/landing/taxi area - encountered, pilot in command
- Nose gear collapsed, landing

## Analysis

THE PILOT WITH ONE PASSENGER ABOARD THE AIRPLANE, INITIATED A TAKEOFF.  HE STATED THAT DURING INITIAL CLIMB THE STALL WARNING HORN WENT OFF AND HE FELT THE WING SHUDDER.  HE ELECTED TO LAND THE AIRPLANE.  A FORCED LANDING WAS MADE TO AN OPEN FIELD.  A POST ACCIDENT EXAMINATION OF THE AIRPLANE FAILED TO REVEAL ANY MECHANICAL MALFUNCTIONS WHICH WOULD HAVE CONTRIBUTED TO THE ACCIDENT.
