A Vickers Viscount crashed shortly after takeoff when the crew attempted a ditching over the sea but stalled, resulting in the deaths of all four crew members and seven passengers.

What happened

The incident occurred during the initial climb phase shortly after departure. Engine number 3 failed, prompting the captain to initiate an emergency procedure involving a ditching over the sea. However, the Vickers Viscount stalled before reaching open water. The aircraft struck palm trees and impacted the ground approximately five kilometers from the airport.

The crash resulted in significant loss of life. All four crew members and seven passengers were killed. Three additional passengers sustained injuries, while six others remained unhurt. The airframe was destroyed upon impact.

Findings

Official investigations determined that the exact technical cause of the failure on engine number 3 could not be established. However, authorities concluded that the crew inadvertently shut down engine number 4 instead of engine number 3. This error caused the heavy aircraft to lose altitude rapidly, leading to the stall and subsequent crash.

Probable cause

The crew mistakenly shut down engine number 4 rather than the failed engine number 3, causing a loss of altitude that led to a stall and crash.
