## Probable cause

ENGINE FAILIURE RESULTING FROM MAINTENANCE DISCREPANCIES.

## 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, approach - vfr pattern - final approach
  - induction air control,intake manifold - leak (contributing factor)
  - operation with known deficiencies in equipment - intentional, pilot in command (contributing factor)
  - fuel system,electric fuel trimming - pressure excessive (contributing factor)
  - in-flight planning/decision - improper, pilot in command (contributing factor)
  - maintenance - poor, other maintenance personnel (cause)
- Forced landing, descent - emergency
- Nose over, landing - roll

## Analysis

ACCORDING TO THE PILOT, THE ENGINE WAS NOT RUNNING NORMALLY WHILE ON A NIGHT CROSS COUNTRY FLIGHT FROM DALLAS, TEXAS, TO ENGLEWOOD, COLORADO. INSTEAD OF RETURNING TO DALLAS OR LANDING AT THE NEAREST SUITABLE AIRPORT, HE ELECTED TO CONTINUE HIS FLIGHT. UPON ARRIVAL AT HIS DESTINATION, AND WHILE ON FINAL APPROACH, HE ATTEMPTED TO ADD POWER BUT THERE WAS NO RESPONSE FROM THE ENGINE. THE AIRCRAFT WAS LANDED SHORT OF THE RUNWAY ON SOFT TERRAIN. THE NOSE GEAR SEPARATED FROM THE AIRCRAFT AND THE AIRCRAFT NOSED OVER. THE INVESTIGATION REVEALED MAINTENANCE DISCREPANCIES WHICH PREVENTED NORMAL ENGINE OPERATION.
