On September 23, 1956, a Curtiss C-46 Commando (registration CF-IHR) operated by World-Wide Airways was involved in an aviation accident near Mackar Inlet, Canada during landing or approach. No fatalities were reported. Investigators recorded the probable cause as: The aircraft failed to come to a complete stop before the end of the runway, leading to an overrun into rocky terrain. 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 experienced an overrun following touchdown at the Mackar Inlet DEW Line site, resulting in significant damage to the airframe.
What happened
During an arrival at the Mackar Inlet DEW Line site (station number 28), the aircraft failed to decelerate sufficiently after making contact with the runway. Unable to halt within the available runway length, the aircraft continued past the end of the landing strip and entered a rocky terrain area. The force of the overrun caused the separation of the undercarriage.
While the impact resulted in the airframe being damaged beyond repair, there were no casualties reported. Both members of the crew escaped the incident without injury.
Findings
The aircraft was unable to stop within the remaining distance available after touchdown.
Probable cause
The aircraft failed to come to a complete stop before the end of the runway, leading to an overrun into rocky terrain.
