Oil Filler Cap Missing Before Departure Leads to Accident (N2452S)

On August 17, 2004, a Cessna T210L (registration N2452S) was involved in an aviation accident near Tulsa, OK. Investigators recorded the probable cause as: 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. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

An aircraft on departure from runway 19R reported oil on the windscreen and attempted to return. Witnesses observed the airplane slow and bank before impacting terrain. Investigation revealed the engine oil filler cap was missing.

Departure and Pilot's Report

The airplane took off from runway 19R shortly before the accident. Moments after becoming airborne, the pilot contacted the tower and requested to return to the airport, citing oil accumulating on the windscreen.

Witness Observation

A pilot who was taking off immediately behind the accident airplane reported seeing it turn right at approximately 300 feet above ground level. The witness described the airplane as appearing very slow, and shortly thereafter, it rotated toward the ground.

Postimpact Examination

Examination of the wreckage revealed that the engine oil filler neck did not have a cap installed. The filler neck was partially compressed, and the oil cap was found on a chain nearby, undamaged. Pieces of the windscreen Plexiglas, coated with oil, were discovered outside the main wreckage zone.

Engine Manufacturer's Perspective

A representative of the engine manufacturer stated that the engine could probably operate for 15 to 25 minutes without a cap on the oil filler neck.
