Probable cause
The proper touchdown point not obtain/maintained by the pilot following a single-engine approach to landing. Contributing factors were the vacuum pump oil leak, the low oil pressure of the propeller control system, and the unfeathered propeller.

Read the full NTSB narrative
The airplane touched down short of the landing runway following a loss of right engine oil pressure during cruise flight at 16,000 feet. The pilot stated that with the loss of oil pressure, he could "easily" make it to the destination. While on final approach and in reported visual conditions, the pilot cancelled his instrument rules flight plan and executed a visual approach. On short final, the oil pressure dropped to zero. He then shutdown the right engine and was not able to get the right engine propeller feathered. He touched down about 7 feet short of the runway. Examination of the airplane revealed that the vacuum line and wing boot deice lines were full of oil. The right engine turbocharger was "seized-up." Examination of the turbocharger bearings and shaft did not show evidence of overheating. The turbocharger bearings and shaft displayed evidence of circumferential wear consistent with normal operation. The right engine driven vacuum pump was "full" of oil and contained an internal oil separator.
