## Probable cause

The loss of engine power during the initial climb due to decreased engine oil quantity and pressure as a result of the engine's oil cap not being adequately secured.

## Findings

NTSB's coded findings; those marked are part of the probable cause.

## Analysis

Shortly after departure, when the airplane was approximately 250-feet above ground level, oil began to spray onto the windshield. The pilot checked the engine gauges and noticed a drop in oil pressure. As the pilot turned onto the crosswind leg of the traffic pattern, the engine started to operate abnormally and he performed a 180-degree turn back to the runway. The airplane touched down on the last 250 feet of the runway and proceeded through a fence. The airplane sustained substantial damage during the impact with the fence and came to rest upright, among several parked buses. A postaccident examination of the airplane by a Federal Aviation Administration inspector revealed that the engine’s oil cap was hanging by its chain not secured on the engine case. The cap’s gasket appeared worn; however, the inspector could not determine when the cap came off. The pilot reported that the engine was serviced with oil prior to the flight and that he thought that the oil cap was secured afterward.

## Factual narrative

Shortly after departure, when the airplane was approximately 250-feet AGL (above ground level), oil began to “spray” on to the windshield. The pilot then checked the engine gauges and noticed a drop in oil pressure. As the pilot turned to the crosswind leg, the engine started to run “rough”, and he elected to conduct a 180-degree turn back to the runway. The airplane landed on about the last 250-feet of the runway and proceeded through a fence. The airplane sustained structural damage during the impact with the fence and came to rest upright, among several parked buses. An examination of the airplane by a Federal Aviation Administration Inspector, revealed that the engine’s oil cap was off and hanging by its chain. The cap’s gasket appeared “worn”; however, the inspector could not determine when the cap came off. He added, that the pilot stated that the engine was serviced with oil prior to the flight, but the oil cap was secured.
