NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

Shortly after takeoff on runway 30L the pilot noted oil on the windshield. He contacted ATC and was cleared to land on any runway. The pilot chose runway 04 as he was 'anxious' to land the airplane. The airplane touched down off the left side of the runway, bounced up onto the runway and off the right side. It bounced again contacting runway lights on the right side of the runway. The airplane slowed as it traveled into the grass off the right side of the runway. The pilot regained control of the airplane and taxied back to the runway, then onto the taxiway. Postaccident inspection revealed the clip, which connected the oil filler cap to the chain, was binding. This could have given the false sensation that the filler cap was secured when in fact it may not have been. The oil filter and oil had been changed just prior to this flight. The pilot stated he checked the oil during the preflight after which he secured the cap.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

the pilot misjudged his planned approach during the precautionary landing and the failed to obtain a proper touchdown point. Factors relating to the accident were: the loose oil filler cap, the uneven terrain on which the landing was made, the runway lights which were contacted, and the pilot's anxiety concerning the loss of oil and its effect on possible engine problems.
