## 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 maintained, pilot in command (cause)
  - stall/mush - inadvertent, pilot in command (cause)
- In flight collision with terrain/water, takeoff - initial climb

## Analysis

THE PILOT STARTED A TURN AT LOW ALTITUDE AFTER TAKEOFF AND THE AIRCRAFT STARTED TO SINK. SINCE HE WAS HEADED FOR TREES, THE PILOT ALLOWED THE AIRCRAFT TO SETTLE TO THE GROUND IN A RESIDENTIAL BACKYARD. THERE WAS NO MALFUNCTION OF THE AIRCRAFT TO CONTRIBUTE TO THE OCCURRENCE, BUT A HARD LANDING COLLAPSED THE LANDING GEAR.
