Flight and Oil Leak
The pilot reported that the flight was the first following the airplane's annual inspection. Departing from runway 16, the airplane proceeded to a point 5 to 10 miles south of the airport when oil gushed from the front of the plane, covering the windshield. The pilot was unable to see through the windshield at all.
Attempted Landings
The pilot returned to the airport and attempted to land on runway 34 but was too high and fast. She then entered the traffic pattern for runway 16. After landing, she applied the brakes, but by then there was not much runway left. The airplane overran the runway and impacted a metal pipe.
Accident and Damage
An FAA inspector examined the airplane and found that the nose gear had collapsed and there was damage to the firewall. The inspector determined that the source of oil on the windshield was a displaced crankshaft seal.
Post-Accident Examination
Examination of the airplane's maintenance records by the inspector revealed that the mechanic who performed the annual inspection had replaced the crankshaft plug but not the crankshaft seal.
