Five of the fatal accidents involved cargo flights and five passenger flights. However, it was also revealed that when all airline incidents were taken into account, including those by cargo planes and commercial passenger turbo prop aircraft, there were a total of 10 fatal accidents that resulted in 44 fatalities onboard and 35 persons on ground.
There were no commercial passenger jet deaths in the world in 2017 and the U.S. president took to Twitter to suggest he had a role in this figure.
According to To70 data, every 16 million flights are one fatal accident, although the calculations were made before the Costa Rican accident.
There were no fatal commercial, passenger jet accidents in 2017, according to two new studies, including one from airline consultant To70.
Adrian Young, of To70, says "Twenty-seventeen is the safest year for aviation ever.' On ther hand he admits civil aviation still has "a very high risk". In comparison to these figures, 2016 was a year which witnessed a total of 16 accidents and 303 deaths among all airliners.More news: Mighty Mayfield can't propel Oklahoma to win in Rose Bowl

The low number of accidents comes as no surprise, according to ASN President Harro Ranter: "Since 1997 the average number of airliner accidents has shown a steady and persistent decline, for a great deal thanks to the continuing safety-driven efforts by global aviation organisations such as ICAO, IATA, Flight Safety Foundation and the aviation industry".
On December 31, aviation had a record period of 398 days with no passenger jet airliner accidents, the ASN said.
One out of 10 aeroplanes involved in an accident was operated by an airline on the European Union "blacklist".
There are more commercial flights now than ever. Still the lowest numbers in modern aviation history.
