Analysis

The acft contacted livestock, a fence and the gear collapsed during a forced landing following a loss of pwr on the right eng. The plt reported that after he feathered the right eng prop and lowered the gear he noted the aux hydraulic system pressure gage was indicating zero. Post accident inspection disclosed evidence of an oil leak from the left lower section of the right eng. Tests revealed the leak originated from the oil cooler pressure line which failed due to severe corrosion of the wire braid and deformation of the inner cover. Testing of the aux hydraulic pressure pump disclosed the 35 ampere current limiter was blown and 40 amperes were required to drive the pump motor.
