Aircraft Crash in River Bed After Takeoff from Juliaca-Inca Manco Capac Airport (OB-R-1020)

Incident Overview and Sequence of Events Following takeoff from runway 29 at Juliaca-Inca Manco Capac Airport, the aircraft experienced difficulties in gaining altitude. As it passed over the runway end at a low height, the crew initiated the landing gear retraction, flap retraction, and power retardation procedures. Despite these actions, the aircraft failed to climb and continued to fly at a low altitude for approximately 1,800 meters before striking obstacles and crashing into a river bed located about 2.5 kilometers from the runway end. The aircraft was destroyed upon impact. ## Casualties and Damage The accident resulted in the deaths of 12 occupants, while 57 others sustained injuries. The aircraft was completely destroyed upon impact with the terrain. ## Official Probable Cause The official investigation determined that the probable cause of the accident was a wrong takeoff configuration on the part of the crew, who failed to follow the published procedures. This error caused the aircraft to adopt an excessive angle of attack after liftoff, which subsequently led to an aerodynamic stall.
