An aircraft experienced a landing gear failure during its takeoff run, resulting in a runway excursion and significant damage to the airframe.

What happened

While performing a takeoff maneuver, the aircraft experienced a structural failure of the undercarriage at high velocity. This collapse caused the plane to lose stability on the runway surface, leading to a skid across the pavement. The movement continued until the aircraft eventually reached a complete stop.

There were no injuries reported among the two pilots involved in the incident. However, the impact and subsequent sliding resulted in the aircraft being declared a total loss, as it sustained damage that was beyond the possibility of repair.

Findings

  • The primary factor in the accident was the collapse of the undercarriage during the high-speed portion of the takeoff roll.

Probable cause

The landing gear failed structurally while the aircraft was accelerating for takeoff.
