Analysis

After a loss of oil pressure the acft was landed downwind. During the precautionary landing across plowed furrows, the rt wing caught in the sugar cane crop and the acft turned to the rt, collapsing the left landing gear and damaging the left wing. The plts attention was caught by the smell of hot oil during the flt. The plt later told FAA inspectors that an oil return line had ruptured and he landed to prevent further damage to the engine. Examination revealed that the rubber oil line (hose) had been subjected to high temperatures; rudder inside the woven steel casing was brittle. The last 100 hr inspection was performed 3 flt hours before the accident.
