## Sequence of events

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

- Loss of control - on ground/water, landing - roll
  - propeller system/accessories - improper (cause)
  - propeller governor control - asymmetrical (cause)
  - throttle/power control - not maintained, pilot in command
  - throttle/power lever - improper (cause)
- On ground/water collision with object, landing - roll
  - object - runway light (contributing factor)

## Analysis

THE PILOT REPORTED THAT THE APPROACH SEQUENCE AND PROFILE WERE NORMAL, AND THERE WERE NO APPARENT AIRCRAFT PROBLEMS. AFTER TOUCH DOWN THE PILOT APPLIED REVERSE THRUST. DURING THE LANDING ROLL OUT, THE AIRCRAFT VEERED OFF THE LEFT SIDE OF THE RUNWAY, COLLIDED WITH A TAXIWAY MARKER AND A RUNWAY LIGHT. THE AIRCRAFT EXAMINATION DISCLOSED THAT, THE LEFT PROPELLER GROUND STRIKE HAD OCCURRED. WHEN PULLED INTO REVERSE, THE THROTTLE LEVERS COULD OVERLAP, CAUSING A DIFFERENCE IN THE FUEL CONTROLLER READING ON EACH ENGINE. THE ENGINE EXAMINATION DISCLOSED THAT THE RIGHT ENGINE NEGATIVE TORQUE SENSING CAMSET WAS DISPLACED TWO TEETH FROM THE INSTALLED REFERENCE POINT. THIS CONDITION PREVENTED THE RIGHT PROPELLER FROM COMING OUT OF THE FEATHER POSITION DURING THE POST INCIDENT EXAMINATION.
