Westcliffe, CO, USA
N71AJ
CROSS DAVID L GLASAIR III
After leveling off at 12,000 feet mean sea level for a test flight, the pilot noticed that the oil temperature began to increase, and then the engine lost oil pressure. The engine then lost total power, and the pilot performed a forced landing in a field. An examination of the engine revealed that a gasket between the remote oil filter adapter and the "spin-on" filter mounting pad had failed, which resulted in a loss of oil. The owner reported that he had lubricated the gasket with a compound upon installation. It could not be determined whether the compound had degraded the gasket.
