## Probable cause

FAILURE OF THE PILOT TO ATTAIN ADEQUATE AIRSPEED TO CLIMB, WHICH RESULTED IN A STALL/MUSH.  THE TREES WERE A RELATED FACTOR.

## 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)
  - climb - not possible, pilot in command
  - stall/mush - inadvertent, pilot in command (cause)
  - lack of total experience, pilot in command
- In flight collision with object, takeoff
  - object - tree(s) (contributing factor)

## Analysis

DURING TAKEOFF, THE AIRPLANE LIFTED OFF AT 60 TO 65 MPH. ONCE AIRBORNE, IT WOULD NOT CLIMB AND IT SETTLED INTO TREES OFF THE DEPARTURE END OF THE RUNWAY. THE AIRPLANE WAS REPORTED TO HAVE HAD A BEST ANGLE OF CLIMB SPEED OF 70 MPH AND A BEST RATE OF CLIMB SPEED OF 84 MPH.  THE PILOT HAD A TOTAL TIME OF 111 HOURS WITH 47 HOURS IN THIS MAKE AND MODEL.
