Varig Flight 797

Background

Aircraft

The aircraft involved was a Boeing 707-379C, registered as PP-VJK, that first flew in 1968. It was powered by four Pratt & Witney JT3D-3B turbofan engines. PP-VJK was Varig's final passenger Boeing 707, and the aircraft's final flight with Varig, having already been sold to the Brazilian Air Force.

Crew

The flight crew consisted of Captain Júlio César Carneiro Corrêa (38), First Officer Nélson Figueiredo, and Flight Engineer Eugênio Cardoso.

Accident

On 2 January, during the aircraft's penultimate flight to Abidjan, the fire alarm for the outer left (No. 1) engine sounded. Another airline, Air Afrique, which performed maintenance for Varig, inspected the engine and determined that it was a false alarm. In the early morning hours of darkness on 3 January, the aircraft departed Port Bouet Airport in Abidjan. 20 minutes after departure and 200 km from Abidjan, the fire alarm for the no. 1 engine sounded a second time. Flight engineer Cardoso reported high fuel temperatures in the engine, but the other engines were functioning normally. As a precaution, captain Corrêa shut down the faulty engine and decided to return to Abidjan.

Cardoso then reported a fuel leak on engine no 1, though the crew had difficulty identifying it. A flight attendant reported that a passenger had observed engine no. 1 emitting fire. As the aircraft flew over Abidjan, the tower controller at Port Bouet Airport cleared the flight to land on runway 03, the closest available runway. Even though the weather was suitable for a visual approach, captain Corrêa requested to land on runway 21 instead, as it was equipped with an instrument landing system (ILS). However, this approach required additional maneuvers, including a left turn onto a 270 degree heading. The crew (possibly in an attempted to prevent asymmetric thrust) decided to delay extending the flaps and the landing gear until turning past the VHF omnidirectional range. With the flaps retracted, the aircraft flew faster to prevent a stall.

During the turn, the stick shaker (stall warning) was activated and the ground proximity warning system emitted several "bank angle" warnings. The aircraft rolled 90 degrees to the left, stalled, and crashed on a rubber plantation in the midst of the jungle 18 km from the airport at a speed of 400 km/h.

Victims

Nationalities of the persons on board:

Three people (all passengers) initially survived, though one died several hours later. Four days after the disaster, a British passenger died of his injuries on board a Swiss aircraft while arriving in Paris; he was going to be transferred to a burn unit in a Paris suburb. The sole survivor, identified as an Ivorian university professor, had burns on less than 20 percent of his body. While being interviewed by investigators, the professor said that more people had survived the initial impact but died of burns. He also stated that he managed to drag the British passenger who initially survived, away from the wreckage of the aircraft. The sole survivor died of a heart attack on 4 March 2015 at the age of 72.
