The retiree was on Voepass Airlines Flight 2833 bound for São Paulo-Guarulhos International Airport in São Paulo, where she was scheduled to take a connecting flight to Brasilia to visit her 93-year-old mother, her brother and granddaughters.

'I lost my best friend,' Denilda Acordi's sister, Ines Pavanelli, 60, told UOL Noticias. 'Our mother is 93 years old and still doesn't know about the tragedy.'

Denilda Acordi was a widow and had three children and six grandchildren. She was the oldest of nine siblings.

A retired owner of an accounting firm, she devoted her free time to visiting patients in area hospitals.

'God and family always came first, and whenever she could, she practiced charity in different situations,' her son said. 'So, as she was a very charitable woman, she took part in several projects and helped many people. She didn't seek publicity with this, none at all.'

'(She) had a simple life and lived to give her time to those who needed it the most,' Pavanelli said. 'I will forever remember her last message on WhatsApp before boarding the plane, which said, "Inês, thank you for the coat, it's really cold here. I'm going to wear it, I won't be without it. Then, I'll give it back to you later. Thank you." '

On Monday, the Aeronautical Accident Investigation and Prevention Center announced that it had finished it preliminary report on the plane crash that killed 58 passengers and four crew members

Denilda Acordi's daughter has been gathering some of her personal items to help authorities identify her remains through DNA testing.

'My niece called me to say that she has started collecting genetic material, presenting documentation and examining dental records,' Pavanelli said. 'This is the only way to identify some of the bodies that are very charred. We still don't know what my sister's condition is. The identification process could take months.'

According to Pavanelli, Voepass Airlines has made flights available for family members to travel to São Paulo and assist with identifying the remains of their loved ones.

'They told us that at first they will try to identify them using dental records. They asked that the relatives tested be (immediate family members). They said that some bodies were not completely charred,' Pavanelli said.

At least 16 of the 62 victims had been identified as of Monday, according to the Forensic Medical Institute in São Paulo.

The Aeronautical Accident Investigation and Prevention Center, which is under the supervision of the Brazilian Air Force, finished its preliminary report Monday.

'On the route between Cascavel and Guarulhos, the aircraft suddenly lost altitude and crashed into the ground,' the report stated.

The Voepass Airlines ATR-72-500 turboprop aircraft took off from Cascavel Regional Airport at 11:46 a.m.

Flightradar 24, which provides flight data, showed that the airplane reached an altitude of 17,000 feet 24 minutes into the flight.

The aircraft transponder indicated a loss of altitude at a rate between -8,000 feet to -24,000 feet per minute in the last 60 seconds of the flight.
