Analysis
The eng seized approximately 3500 ft & the acft was ditched off the beach. The right mag distributor block showed evidence of carbon tracking & cross firing. Neither end of the right mag had breather plugs installed. All spark plugs were excessively fouled & severely eroded. Springs on the spark plugs leads were burned & dirty. The #1 conrod was splitlengthwise & was in several pieces. Examination of the log book showed improper maintenance practices such as overhauling a cylinder & installing detergent type oil. No evidence of compliance with teledyne service bulletin #612 could be found. This bulletin recommends periodic maintenance procedures to establish cleaning & inspection guidelines governing bendix magnetos & ignition harnesses.
