Circumstances:
Six minutes after takeoff from Santa Rosa de Yacuma Airport, en route to La Paz, the flight engineer informed the captain that the left engine caught fire. The crew shut down the engine and feathered its propeller. The captain decided to attempt an emergency landing on an abandoned airfield located in El Triunfo, about 24 km north of Santa Rosa de Yacuma Airport. After landing, the aircraft rolled for about 100 metres when the left main gear collapsed. The aircraft veered to the left and rolled for few dozen metres before coming to rest, bursting into flames. All three crew members escaped uninjured and the fire partially destroyed the left part of the aircraft.
Probable cause:
Fire of the left engine after takeoff for unknown reasons.

Captain / Total flying hours:
3500
Circumstances:
Shortly after climbing and leveling at 6,000 feet, the right engine bmep gage indicated a rapid power loss and the right engine rpm 'increased out of control' to about 3,100 rpm. The aircrew retarded the right throttle and reduced the right engine to 2,100 rpm by using the prop increase/decrease toggle switch. The aircrew were unable to feather the right propeller or maintain altitude, so they diverted to the nearest airport (Walker County). While turning downwind for runway 09, the right engine fire indicator activated and the copilot confirmed a fire. Both fire bottles were discharged and the right propeller stopped rotating. Injection water for the left engine was exhausted and the left engine began backfiring. The captain then maneuvered and landed on runway 27. After touchdown, the right main tires failed, the aircraft veered off the right side of the runway and hit a ditch and the gear collapsed. An exam revealed the #6 cylinder link rod and/or piston in the right engine had failed, resulting in further damage to the engine and #6 cylinder. Subsequently, fire and heat caused the right engine to seize and also damaged the right main tires which failed at touchdown. All 39 occupants were evacuated, among them two passengers were seriously injured.
Probable cause:
Occurrence #1: loss of engine power
Phase of operation: cruise
Findings
1. (f) engine assembly, connecting rod - failure, total
