Lima - Pucallpa - Iquitos

On December 24, 1971 at 12:36 PM, Lima - Pucallpa - Iquitos experienced a crash involving Lockheed L-188 Electra, operated by LANSA Peru - Lineas Aéreas Nacionales del Peru, with the event recorded near Puerto Inca Huánuco.

The flight was categorized as scheduled revenue flight and the reported phase was flight at a mountains crash site.

92 people were known to be on board, 91 fatalities were recorded, 1 survivors were identified or estimated. This corresponds to an estimated fatality rate of 98.9%.

Crew on board: 6, crew fatalities: 6, passengers on board: 86, passenger fatalities: 85, other fatalities: 0.

The listed crash cause is weather. While cruising at an altitude of 21,000 feet on a flight from Lima to Pucallpa, the crew encountered poor weather conditions with thunderstorm activity and severe turbulences. It appears that lightning struck the right wing that caught fire and later detached. As the pilot-in-command attempted to stabilize the airplane, turbulences caused a structural failure of the left wing. Out of control, the airplane dove into the ground and crashed in flames in a jungle located in a mountainous area in the region of Puerto Inca. Debris and dead bodies were found in a large area. A female passenger aged 17, Juliane Koepcke, was ejected at impact and was the only survivor. Despite her injuries (a broken collar bone, a deep gash to her right arm, a concussion and an eye injury), she walked away for 10 days and was eventually rescued by lumbermen.

Aircraft reference details include registration OB-R-941, MSN 1086, year of manufacture 1959.
