On March 8, 1967, an Aviation Traders ATL-98 Carvair (registration F-BMHU) operated by Compagnie Air Transport - CAT was involved in an aviation accident near Karachi-Muhammad Ali Jinnah-Quaid-e-Azam, Pakistan during takeoff. 13 people were killed. Investigators recorded the probable cause as: The loss of power in the right engine combined with insufficient performance from the left engine prevented the aircraft from maintaining altitude. This summary draws on records from the Bureau of Aircraft Accidents Archives (B3A); 2 related events involving the same aircraft type or operator are linked below.
An aircraft crashed into a bridge shortly after takeoff, resulting in thirteen fatalities including crew and individuals on the ground.
What happened
During the initial climb phase of flight, an aircraft experienced significant difficulties maintaining altitude. While attempting to gain height, the plane collided with a bridge spanning Drig Road. The impact led to a crash that resulted in the deaths of six crew members and seven people on the ground, totaling 13 fatalities.
Findings
Investigations into the accident determined that the aircraft suffered a mechanical failure during its departure. Specifically, the right engine failed while the plane was climbing, and the remaining left engine was unable to produce enough thrust to sustain flight levels.
Probable cause
The loss of power in the right engine combined with insufficient performance from the left engine prevented the aircraft from maintaining altitude.
