What happened
During a landing attempt at Manaus-Eduardo Gomes Airport, a four-engine airplane experienced a runway excursion on a surface made slick by heavy rainfall. After the aircraft made contact with the wet runway, it drifted toward the right side of the pavement. During this deviation, the right main landing gear collided with runway lighting installations.
The force of the collision caused the right main gear to be completely detached from the airframe. The aircraft eventually came to a halt following the impact. While the aircraft sustained damage that rendered it a total loss, all three crew members were able to exit the wreckage without sustaining any injuries.
Findings
Investigation into the event suggests that the aircraft was traveling at an excessive speed of 148 knots upon touchdown. The combination of high approach velocity and the presence of heavy rain on the runway surface likely led to the incident. It is noted that aquaplaning may have occurred, preventing the tires from maintaining proper contact with the runway surface and leading to the loss of directional control.
