Narrative:The Douglas DC-6 departed Villavicencio for Mitu at 12:06. The airplane carried eleven 55-gallon oil drums and twelve passengers. The DC-6 took off from runway 22 and the undercarriage was retracted. At that moment noises were heard from the no. 2 engine. The engine lost power.
The captain decided to return to the airport. He initiated a left hand turn in order to land back on runway 22. On finals the flight engineer feathered the no. 2 propeller. The airplane touched down far down the runway. It overran the runway and collided with a stone wall.
Probable Cause:
PROBABLE CAUSE (translated from original Spanish report):
Poor planning by the pilot and crew in the execution of the landing maneuver that led to an unstabilized and fast approach with runway contact at 1700 feet and an unnecessary feathering of the engine No. 2 that cancelled the operation of the hydraulic system of the main brakes, in addition there was a late application of the brakes, allowing the plane off the runway.
