## Probable cause

THE PILOT INITIATED AN EMERGENCY LANDING WHEN THE ENGINE RPM WENT TO ZERO DUE TO A BROKEN TACHOMETER CABLE. HE DID NOT ATTAIN THE PROPER TOUCHDOWN POINT AND OVERRAN THE END OF THE RUNWAY.

## Sequence of events

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

- Overrun, landing - roll
  - engine instruments,tachometer - failure,total (contributing factor)
  - emergency procedure - initiated, pilot in command
  - proper touchdown point - not attained, pilot in command (cause)
- On ground/water encounter with terrain/water, landing - roll

## Analysis

THE PILOT HAD ENTERED DOWNWIND FOR A LANDING ON RUNWAY 27 AND WAS ABOUT THE MID POINT OF THE RUNWAY WHEN THE ENGINE RPM DROPPED TO ZERO.  THE PILOT MADE AN EMERGENCY DESCENT TO THE RUNWAY AND AFTER GETTING ALIGNED WITH THE RUNWAY THE AIRPLANE WAS STILL HIGH.  THE PILOT LOWERED THE NOSE IN AN EFFORT TO LAND ON THE RUNWAY PAVEMENT, HOWEVER, HE TOUCHED DOWN WITH ABOUT 20% OF THE RUNWAY REMAINING.  THE AIRPLANE DEPARTED THE RUNWAY INTO A GRASSY MARSH AND NOSED OVER.  THE EXAMINATION OF THE WRECKAGE REVEALED A BROKEN TACHOMETER CABLE.
