## Probable cause

The loss of engine power as a result of both sets of magneto points failing to open due to excessive wear of the nylon cam followers.  The excessive wear of the cam followers was due to maintenance personnel's failure to follow the magneto manufacturer's recommended maintenance procedures and inspect the cam follower felt pads for adequate lubrication at 100-hour intervals.  A factor was the lack of suitable terrain available for the forced landing.
