Analysis

The acft was landed in the tops of small spruce trees after the engine lost oil pressure and was shut down. The plt later admitted that the oil lines needed relacement on the last annual on 06-22-84 but he postponed it and later forgot to do it in the excitement of re-flying on floats after a 2 year lay-off. A badly deteriorated oil outlet line from the oil cooler had failed losing oil and pressure.
