Narrative:
The aircraft took off from Brasília, Brazil on a flight to the Campo de Marte Airport, São Paulo, Brazil with one pilot and three passengers.
During the flight the weather conditions, which initially were favorable, deteriorated. Upon arrival at the destination, the airport started to operate under VFR Special conditions. The pilot was cleared for an approach to runway 30. The landing took place in heavy rain and during the landing roll out, when applying the brakes, the pilot realized that it did not have effectiveness in the braking of the aircraft. He then used the emergency brake.
The aircraft left the runway on the right side and stopped after the left main landing gear broke.

1 Human Factor
1.1 Medical Aspect
Nothing to report.
1.2 Psychological Aspect
1.2.1 Individual Information
Nothing to report.
1.2.2 Psychosocial Information
Nothing to report.
1.2.3 Organizational Information
Nothing to report.
1.3 Operational Aspect
1.3.1 Concerning the operation of the aircraft
a) Adverse weather conditions - contributed
The runway became flooded and impractical due to heavy rainfall that interfered with the operation of the aircraft and led to abnormal circumstances.
b) Airport infrastructure - contributed
There was no efficient drainage system at the aerodrome, allowing the entire runway to be contaminated at the time of the accident, which contributed to hydroplaning and consequent low braking effectiveness of the aircraft.
There was no standardized procedure for the evaluation of the runway in relation to the presence of water (wet or contaminated) and its transfer to the air traffic control units to inform the pilots, which contributed to the pilot not knowing in advance that the runway was contaminated.
c) Instruction - contributed
The aircraft training program did not include specific training for landing on short runways and for varying runway conditions such as wet and contaminated.
d) Pilot judgement - contributed
The pilot judged that he could use the brakes of the aircraft differently than specified in the manuals, which contributed to the locking of the wheels during the run after the landing.
