## Factual narrative

While the helicopter was running on the runway, the pilots noticed that the number two engine parameters were below prescribed values and decided to abort the take-off. After leaving the runway and entering the company apron, the pilots saw company mechanics signalling that there was fire from the number two engine cowl. The number two engine fire light illuminated, the captain activated the fire protection system on the number two side, while the copilot coordinated an evacuation of the passengers. The company mechanics extinguished the fire. According to the Brazilian authorities, the number two engine had a failed stage in the compressor section. This investigation is under the jurisdiction of the Government of Brazil.
