## Probable cause

The failure of the pilot to maintain adequate airspeed while attempting to make a precautionary landing, which resulted in a stall/spin and collision with the terrain.  A factor in his failure to maintain an adequate airspeed is the pilot's likely diverted attention to the oil loss problem and pending engine failure.  An additional factor is the pilot/mechanic's improper installation of an unapproved oil hose, which ruptured under pressure.
