The Yakovlev Yak-40 overran the runway, fell into the bed of the Saposoa River and broke up, killing six of the 31 occupants.
The Yak-40 was new to the fleet of Servicios Aéreos Amazonicos and a Ukrainian instructor pilot was in the cockpit along with a copilot and an observer pilot of the airline.
The aircraft operated on a domestic flight from Trujillo to Saposoa. Weather at the destination was poor due to rain in the area. On final approach the crew lost sight of the runway. The copilot suggest the initiate a go around, but the captain continued the approach at very low altitude. Noticing the treetops, the copilot advanced the throttles to go around, but the captain intervened and retarded the throttles. The aircraft touched down about half way down the runway on the left-hand edge.
The pilot used the thrust reverser and applied the brakes, but these were not effective on the wet runway. The aircraft overran the runway and ended up in the river.

- Poor weather in the area of the airport
