Narrative:
The Air Tractor AT-502B with registration number TG-SRO, was spraying agricultural products on the Parijuyu farm, located in the municipality of "La Gomera", department of Escuintla. On flight number 4 on the morning of 15 May at approximately 06:00 in the morning, the aircraft was loaded with the corresponding agrochemical product for spraying the banana plantation, then proceeded to take off, but failed, crashing at the southern end of the farm's runway.
The pilot was evacuated from the cockpit of the aircraft and assisted by farm workers, to be taken to a local medical clinic for evaluation and medical attention.

PROBABLE CAUSES:
The cause of the accident was in the take-off phase in which the engine at full power had the blades of the power section discs fracture due to material fatigue, causing the failure, which caused the aircraft to crash.
During the boroscope inspection inside the engine, especially in the combustion chamber, stator, compressor turbine blades and power section, it was found that the blades of discs 2 and 3 of the power section were fractured.
