## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Nose over, takeoff - roll/run
  - landing gear,axle - fractured (cause)
  - terrain condition - rough/uneven

## Analysis

WHILE ON TAKEOFF ROLL FROM AN OPEN FIELD THE RIGHT LANDING GEAR AXLE OF THE BELLANCA 7GCBC SHEARED AT THE END NEAREST THE GEAR LEG.  THE GEAR LEG THEN DUG INTO THE GROUND CAUSING THE AIRCRAFT TO NOSE OVER.
