Incident Overview
On approach to São Paulo-Congonhas Airport, the aircraft completed its landing under conditions of heavy rainfall. The runway surface was contaminated, and after touchdown, the aircraft experienced difficulty in decelerating properly. As the runway end approached, the captain made a decision to veer off the runway to the left.
Sequence of Events
Upon exiting the runway, the aircraft contacted waterlogged ground. The force of this contact caused the undercarriage to be torn off. The aircraft subsequently came to rest in this area. All 88 occupants on board evacuated the aircraft safely, and no injuries were reported. The aircraft sustained damage that rendered it beyond economical repair.
Official Findings
The investigation determined that the aircraft suffered hydroplaning after landing on a wet runway. The braking coefficient was poor due to an excessive accumulation of water on the runway surface, which contributed to the inability to decelerate effectively within the available runway length.
