The engine developed an oil leak resulting in smoke in the cockpit and decaying oil pressure. The private pilot shut off the engine and attempted to land on a local desert airstrip. The airplane landed approximately 50 feet short of the airstrip and contacted several large bushes during the landing rollout. The postaccident investigation disclosed that the oil supply hose from the oil cooler to the engine had ruptured. The hose appeared to be old and heat deteriorated, but was not replaced in conjunction with a recent engine change.
Probable Cause: failure to replace an old and abraded oil feedline hose which led to its rupture and the in-flight loss of engine oil pressure. A related factor was the pilot's misjudgment of distance-to-go versus altitude remaining during the subsequent forced landing.
