Aircraft gear collapse during landing (OY-DSR)

Copenhagen-Kastrup, DenmarkLanding (descent or approach)

On September 13, 1974, a Boeing 720 (registration OY-DSR) operated by Conair of Scandinavia was involved in an aviation accident near Copenhagen-Kastrup, Denmark during landing or approach. No fatalities were reported. Investigators recorded the probable cause as: The left main landing gear failed due to the impact forces of a suspected hard landing. This summary draws on records from the Bureau of Aircraft Accidents Archives (B3A).

An aircraft experienced a structural failure of its left main landing gear during touchdown, resulting in a runway excursion and heavy damage.

What happened

During the landing phase of the flight, the aircraft experienced a significant mechanical failure immediately upon contact with the runway. As the wheels made contact with the ground, the left main landing gear collapsed under the impact. This structural failure caused the aircraft to lose stability and slide for several dozen meters along the surface.

The incident concluded when the movement of the vessel ceased. While the aircraft sustained damage that rendered it a total loss, there were no injuries reported among those on board during the sequence of events.

Findings

Investigations into the accident indicate that the collapse was likely precipitated by a hard landing. The force exerted on the landing gear during touchdown exceeded its structural limits, leading to the failure of the left main gear assembly.

Probable cause

The left main landing gear failed due to the impact forces of a suspected hard landing.
