What happened
During the initial climb phase of flight under visual meteorological conditions, an ATR aircraft experienced a mechanical failure of its right engine. Immediately following lift-off from the airport, the loss of power caused the aircraft to yaw significantly to the right. This maneuver led to a steep right roll, during which the right wing struck power lines. The subsequent impact with the ground resulted in a post-crash fire that consumed the majority of the airframe.
Only the two engines and a small section of the right wing panel survived the intense flames. There were two fatalities among the crew members on board.
Findings
Investigations into the engine failure revealed that the right engine suffered from a lack of lubrication to the impeller shaft. This starvation of oil was caused by a blockage in the oil jet, which was attributed to foreign object debris (FOD). While the oil line connecting the scavenge sump to the scavenge pump inlet had been recently replaced, the specific origin of the debris remains undetermined.
Records indicate that the aircraft had undergone maintenance for an oil leak approximately two weeks before the accident. The investigation concluded that the loss of directional control and the subsequent collision with terrain were driven by the partial loss of engine power due to mechanical malfunction.
