After leaving the runway the aircraft's undercarriage dug into soft ground and then struck a link taxiway where the nose undercarriage collapsed.
CONTRIBUTING FACTORS (translated from Portuguese report)
Operational Aspect
a. Weather conditions - Contributed
A light rain caused the presence of water on the runway, enabling the occurrence of hydroplaning.
b. Infrastructure - Contributed
The accumulation of water on the surface of the runway, as a result of inadequate drainage, lack of "grooving", enabled the hydroplaning.
c. Education - Contributed
The pilot applied full pressure on the right pedal, generating a force to the left that contributed to the departure off the runway.
During hydroplaning, the pilot should not apply pedal to the opposite side to which the aircraft slides; this fact was not covered during the instruction of the pilot.
d. Application of command - Contributed
In the face of hydroplaning, the pilot applied the right pedal, aggravating the departure of the aircraft to the left.
