Four-engine aircraft crash after engine failure during initial climb at Santa Maria Island (XA-GUU)

Santa Maria, PortugalTakeoff (climb)

On September 22, 1948, a Douglas C-54 Skymaster (registration XA-GUU) operated by Aerovias Guest was involved in an aviation accident near Santa Maria, Portugal during takeoff. No fatalities were reported. Investigators recorded the probable cause as: The accident was caused by the loss of power on one engine during takeoff, which led to a stall and runway impact. This summary draws on records from the Bureau of Aircraft Accidents Archives (B3A); 1 related events involving the same aircraft type or operator are linked below.

A four-engine aircraft crashed shortly after taking off from Vila do Porto Airport due to an engine power loss, resulting in no injuries among the 44 occupants but total structural damage.

What happened

The incident occurred immediately following departure from Vila do Porto Airport on Santa Maria Island. The aircraft was operating a scheduled service between Madrid and Mexico City, with this leg serving as an intermediate stopover. During the initial climb phase just after liftoff, the crew experienced a loss of power in one of the four engines. This mechanical failure led to an aerodynamic stall, causing the airframe to descend rapidly and impact the runway surface. The aircraft came to rest on the ground following the collision.

Despite the severity of the crash, all 44 occupants survived without sustaining injuries. However, the structural integrity of the fuselage was compromised to such an extent that the aircraft was declared damaged beyond repair. The event highlighted the critical nature of engine redundancy management during the takeoff phase for multi-engine heavy aircraft.

Findings

Official investigations identified the primary factor as the loss of engine power during the takeoff sequence. This single-point failure in one of the four propulsion units triggered a chain of events that resulted in the stall and subsequent ground impact. The findings underscore the importance of immediate corrective action and go-around procedures when thrust asymmetry occurs at low altitude.

Probable cause

The accident was caused by the loss of power on one engine during takeoff, which led to a stall and runway impact.
