The NTSB's narrative final · quoted from the NTSB record

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.
