## Sequence of events

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

- Airframe/component/system failure/malfunction, approach - vfr pattern - final approach
  - propeller system/accessories - overspeed (cause)
- Forced landing, approach - vfr pattern - final approach
  - planned approach - poor, pilot in command (cause)
- Nose over, landing - roll
  - terrain condition - crop (contributing factor)

## Analysis

THE PLT REPORTS THAT THE PROPELLER RAN AWAY WHEN THE ACFT WAS AT 75 FT AGL ON FINAL APCH FOR LANDING AT A PVT AIRSTRIP. THE PLT SAID HE WAS TO LOW TO CORRECT THE PROPELLER MALFUNCTION AND WAS FORCED TO LAND IN A BEAN FIELD ADJACENT TO THE STRIP. AN FAA INSPECTOR EXAMINED THE PROPELLER AFTER THE ACDT AND OBSERVED DAMAGE TO THE LOW PITCH STOPS; HOWEVER THE INSPECTOR COULD NOT DETERMINE WHAT DAMAGE OCCURRED BEFORE THE ACDT AND WHAT DAMAGE OCCURRED DURING THE ACDT.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
