## Probable cause

oil exhaustion due to an improper oil breather tube installation, which became plugged in flight due to frozen moisture build-up.  The blocked breather tube then created a crankcase over pressure that caused a failure of the crankshaft seal.  The rough, uneven terrain and strong crosswind were factors in the accident.
