THE FAILURE OF OVERHAUL PERSONNEL TO PROPERLY TORQUE THE ENGINE CASE REAR THRU BOLTS.

## Sequence of events

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

- Loss of engine power(total) - mech failure/malf, cruise - normal
  - single engine aircraft
  - engine assembly - undertorqued (cause)
  - maintenance,overhaul - improper, other maintenance personnel (cause)
  - engine assembly,bearing - slipped (cause)
  - engine assembly,connecting rod cap - separation (cause)
  - engine assembly,crankshaft - fractured (cause)
- Forced landing, descent - emergency
- On ground/water collision with object, landing - roll
  - object - sign
- On ground/water encounter with terrain/water, landing - roll
  - terrain condition - ditch

## Analysis

WHILE THE CRUISE FLIGHT AT 9500 FEET THE ENGINE SEIZED.  A FORCED LANDING WAS MADE TO A DIVIDED HIGHWAY.  TRAFFIC FORCED A LANDING IN THE MEDIAN WHERE THE WING HIT A SIGN & VEERED THE A/C INTO A DITCH.  THE ENGINE HAD 121 HOURS SINCE  OVERHAUL.  EXAMINATION OF THE ENGINE REVEALED THAT THE REAR CRANKCASE THRU BOLTS WERE FINGER TIGHT.  THE REAR MAIN  BEARING HAD SPUN, THE NUMBER 1 ROD CAP SEPARATED, AND THE CRANKSHAFT HAD FRACTURED THROUGH THE COUNTERWEIGHT CHEEK.
