NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.

The airplane was departing on runway 19R. Moments after liftoff, the pilot called tower and asked to return to the airport because he was getting oil on his windscreen. A pilot taking off immediately behind the accident airplane observed the airplane, at approximately 300 feet, turn right to return to the airport. He said that the airplane appeared very slow, and then it rotated to the ground. Postimpact examination of the wreckage revealed that the engine oil filler neck did not have a cap on it. The oil filler neck was partially compressed, and the oil cap was found (on a chain) undamaged. Pieces of windscreen Plexiglas were found outside of the wreckage zone, and they were coated with oil. The engine manufacturer's representative said that the engine could probably run for 15 to 25 minutes without a cap on the filler neck.

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
  • The pilot's inadequate preflight inspection by his failure to secure the oil cap, which resulted in oil leakage on the windscreen, obstructing his vision, and his failure to maintain adequate airspeed.
