## 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, takeoff - initial climb
  - lubricating system,oil seal - failure,total (cause)
  - fluid,oil - leak (cause)
  - fluid,oil - starvation (cause)
  - exhaust system,turbocharger - binding(mechanical) (cause)
- Forced landing, descent - emergency
- On ground/water encounter with terrain/water, landing
  - terrain condition - ditch (contributing factor)

## Analysis

THE PLT REPORTED THAT DURING TAKEOFF, THE ACFT WAS CLIMBING THRU ABOUT 50 FT AGL WHEN HE FELT A VIBRATION & NOTED A LOSS OF POWER. SUBSEQUENTLY, THE ACFT TOUCHED DOWN HARD NEAR THE DEPARTURE END OF THE RWY. THE MAIN GEAR COLLAPSED, THEN THE ACFT SLID INTO A DITCH & WAS FURTHER DAMAGED. AN EXAM OF THE ACFT REVEALED THAT THE SHAFT SEAL ON THE TURBOCHARGER HAD FAILED & ALLOWED OIL TO ESCAPE INTO THE EXHAUST SYS. SUBSEQUENTLY, THE TURBO IMPELLER BECAME VERY HARD TO ROTATE.
