Lufthansa Cargo Flight 527 was a Lufthansa Cargo flight scheduled to fly from Rio de Janeiro in Brazil to Dakar, the capital of Senegal. On 26 July 1979, shortly after take-off in Rio, the Boeing 707 flew into a slope and crashed. All 3 crew members, consisting of the captain, the first officer and a flight engineer died; there were no survivors. The principal cause of the crash was the failure of air traffic controllers to pay the necessary attention to each aircraft and ensure the necessary attention to rising terrain.
Accident
The aircraft was a
By the time the controller resumed communications with Flight 527, he saw that the flight was further north than expected due to its greater speed. He then radioed the crew: "Lufthansa, turn right heading 140, just now, over. Lufthansa 527, turn right heading 140 and climb without restrictions." The crew responded: "Roger, leaving 2 thousand, LH 527, turning right heading 140."
Shortly after this transmission, the
Investigation
The main cause was found to be the failure of Brazilian air traffic controllers to pay the necessary attention to each aircraft and thus both stagger the aircraft among themselves and ensure the necessary distances to rising terrain.
The improperly high speed of the Boeing 707 was both due to faulty instructions and monitoring by the controller, as well as the crew passively accepting the dangerous instructions. Normally, the release includes a departure route to a so-called clearance limit, up to which the aircraft is allowed to fly at most. Even when asked by the pilots, air traffic control gave only an unclear answer. In the clearance for LH527 this information was missing, so the crew continued to fly on the set course instead of asking air traffic control for new instructions. For almost all of the last two minutes, there was no communication between LH527 and air traffic control.[2]
