To70 released its Civil Aviation Safety Review for 2017, reporting 111 accidents a year ago, two of which included fatalities - with a total of 13 lives lost.
In 2016 ASN recorded 16 accidents and 303 deaths.
The two fatal accidents in 2017 both involved small regional turbo-prop planes: an Embraer Brasilia lost control in flight in Angola because of an engine failure, and a Czech-built Let 410 crashed on landing at Nelken in Russian Federation.
The fatal accident rate for large airplanes in commercial air transport has been lowered to 0.06 fatal accidents per million flights - a rate of one fatal accident for every 16 million flights.
There were only two fatal accidents involving passenger airliners, both involving small turbo-prop aircraft, and no fatalities involving jets. The most recent incident included in those numbers was the December 31 crash in Costa Rica that killed 12 people, including 10 American tourists.
However, there were 10 fatal airliner incidents which led to the deaths of 44 people on-board and 35 people on the ground, which included cargo and commercial passenger turbo prop aircraft. It was the deadliest such accident in Costa Rica since 1990.
Adrian Young, a senior consultant for To70, told the Independent it is "unlikely that this historic low will be maintained".
The Netherlands-based aviation consultant firm counted a total of 111 accidents with only two resulting in fatalities.
However, he said civil aviation still hides "a very high risk".
The review stated the fact that electronic objects in the check-in baggage can result in possible danger. In his words, the main challenges for flights are new technologies, including lithium-ion batteries, which can cause fire, as well as the possible mental problems of the people on board.
In 2016, 271 people were killed in seven fatal accidents, including the LaMia jet carrying the Brazillian football team in Colombia and an Egyptair flight from Paris to Cairo.
In 2015, the number was higher with 471 people dead in four crashes. No fatal incidents were recorded with a British airline since the 1980s.
