## Sequence of events

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

- Loss of engine power(partial) - mech failure/malf, approach - vfr pattern - final approach
  - propeller system/accessories,prop control unit - loose (cause)
- Loss of control - in flight, approach - vfr pattern - final approach
  - stall - inadvertent, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled
  - terrain condition - ground (contributing factor)

## Analysis

ACCORDING TO THE PILOT AS HE MADE AN APPROACH TO LAND HE ADVANCED THE POWER LEVER TO GAIN MORE THRUST BUT HE FELT THAT THE PROPELLER WENT INTO BETA RANGE DUE TO PLAY IN THE PROPELLER CONTROL LINKAGE. AT APRX 50 FEET AGL AND 200 FEET FROM THE END OF THE RUNWAY, THE AIRCRAFT STALLED AND FELL TO THE GROUND.
