## Probable cause

THE FAILURE OF THE PROPELLER CONTROL SYSTEM FOR UNDETERMINED REASONS DURING A PRECAUTIONARY LANDING AFTER ENCOUNTERING DETERIORATING WEATHER CONDITIONS DURING A VFR FERRY FLIGHT. CONTRIBUTING FACTOR(S) WAS: THE ADVERSE WEATHER CONDITIONS, INADEQUATE PREFLIGHT, A FAILURE OF THE ELECTRICAL SYSTEM FOR UNKNOWN REASONS, AND THE PILOT'S INTENTIONAL GROUND LOOP.

## Sequence of events

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

- In flight encounter with weather, cruise - normal
  - weather condition - obscuration (contributing factor)
  - preflight planning/preparation - inadequate, pilot in command (contributing factor)
- Airframe/component/system failure/malfunction, approach
  - precautionary landing - selected, pilot in command (contributing factor)
  - electrical system - failure,partial (contributing factor)
  - electrical system - undetermined (contributing factor)
  - flight/nav instruments,fluxgate compass - inoperative (contributing factor)
  - missed approach - performed, pilot in command
- Overrun, landing - roll
  - propeller system/accessories,reversing system - failure,total (cause)
  - propeller system/accessories,reversing system - undetermined (cause)
  - propeller system/accessories,reversing system - inoperative (cause)
- On ground/water encounter with terrain/water, landing - roll
  - ground loop/swerve - intentional, pilot in command (contributing factor)

## Analysis

DIVERTED TO AUGUSTA AFTER ENCOUNTERING DETERIORATING WX. LOST INVERTERS, COMPASS SYSTEM DURING ILS, EXECUTED GO-AROUND. SECOND APPROACH MADE VISUAL TO LANDING. PROPS WOULD NOT ENTER FINE PITCH, BRAKING NOT EFFECTIVE. PLT STEERED AIRPLANE OFF RUNWAY DOWN EMBANKMENT.
