Airline safety: 2017 was safest year in aviation history.
According to Top70 reports
The past year has been another exceptionally good year for civil aviation safety. With only two fatal accidents to passenger airliners, both involving small turbo-prop planes, 2017 was much better than could reasonably (and statistically) be expected, and was again better than last year’s remarkable performance.
However, the risks to civil aviation do remain high, as the seriousness of some of the non-fatal accidents shows
Airlines recorded zero accident deaths in commercial passenger jets last year, according to a Dutch consulting firm and an aviation safety group that tracks crashes, making 2017 the safest year on record for commercial air travel.
2017 IN REVIEW
Our to70 Civil Aviation Safety Review examines accidents only to larger passenger aircraft commonly used by most travellers. (See our criteria in the Note below.) We include all causes, whether technical failure, human error or unlawful interference. In 2016, there were 71 civil aviation accidents of which six resulted in fatalities. This year, 2017, the number is even lower; 111 accidents, two of which included fatalities. There were no accidents in 2017 related to unlawful interference. A total of 13 lives lost in two regional airline accidents:
- An Embraer Brasilia[1] lost control in flight in Angola after, reportedly, suffering an engine failure, and
- A Czech-built Let 410[2] crashed on landing at Nelken in Russia.
An estimated three percent growth in air traffic for 2017 over 2016 means that the fatal accident rate for large aeroplane in commercial air transport is again reduced; this time to 0.06 fatal accidents per million flights. That is a rate of one fatal accident for every 16 million flights.
With so few fatal accidents to examine, it is worth remembering that there were also several qute serious non-fatal accidents in 2017. A number of engine related accidents occurred, including the spectacular loss of the engine inlet fan and cowling on an Air France A380[3]. That the aeroplane continued to operate safely to a diversion airport and was then flown home for repair on three engines says a lot about the robustness of the aeroplane. In addition to the non-fatal accidents, there are a number of notable events that have been excluded from the statistics. Examples of these accidents include:
In comparison, there were 16 accidents and 303 deaths in 2016 among airliners.
The deadliest incident last year occurred in January when a Turkish cargo jet smashed into a village in Kyrgyzstan as it tried to land at a nearby airport in dense fog, killing 35 on the ground and all four onboard.
The Aviation Safety Network said 2017 was “the safest year ever, both by the number of fatal accidents as well as in terms of fatalities.”
Over the last two decades aviation deaths around the world have been steadily falling. As recently as 2005, there were 1,015 deaths aboard commercial passenger flights worldwide, the Aviation Safety Network said.
The United States last recorded a fatal airline passenger jet crash in February 2009, when Colgan Air Flight 3407 crashed short of the runway in Clarence Center, New York, killing 49 onboard and one person on the ground.
In 2016, 412 people were killed in the United States in aviation accidents – nearly all in general aviation accidents and none on commercial passenger airlines.
The last fatal passenger jet airliner accident worldwide took place in November 2016 near Medellin, Colombia and the last commercial passenger aircraft crash to kill more than 100 people occurred in October 2015 in Egypt.

South Korea Introduces Cutting-Edge MRO Center for F-35 and IAI
South Korea is set to make waves in the aerospace industry with the establishment of a cutting-edge Maintenance, Repair, and Overhaul (MRO) hub for F-35 fighter jets and IAI (Israel Aerospace Industries) aircraft.
Central to this initiative is the specialization in converting Boeing 777-ERSF, colloquially known as the “Big Twin,” from passenger to freighter configurations. Under the terms of the agreement, IAI will spearhead the conversion of six B777-300ER and B777-200LR aircraft annually, commencing in 2024. This strategic move is in response to the anticipated surge in demand for wide-body freighter aircraft capable of long-haul flights.
Furthermore, South Korea’s forward-looking vision extends beyond aircraft conversion, with plans to establish a Lockheed Martin F-35 maintenance, repair, and overhaul depot at Cheongju Air Base by 2027. This strategic move not only enhances the operational readiness of South Korea’s air force but also positions the nation as a regional hub for F-35 maintenance expertise.
In preparation for this expansion, thirty Republic of Korea Air Force (ROKAF) engineers and technicians are slated to undergo intensive maintenance training in the United States in 2025, a testament to South Korea’s commitment to fostering local expertise and talent.
IAI’s visionary approach to certification and collaboration underscores the potential for transformative change. With plans for the 777-300ERSF certification process set to unfold in Israel, followed by the rigorous scrutiny of regulatory agencies such as the US Federal Aviation Administration (FAA), the stage is set for the ‘Big Twin’ to soar to new heights of success.
In partnership with esteemed entities like STK and Incheon International Airport Corporation, this collaboration promises to unleash a wave of benefits, amplifying the resilience and competitiveness of the Korean aviation sector while catalyzing job creation and economic prosperity.

Can Airline Seat Cushions Be Used As Life Jackets?
In the event of an aircraft ditching into water, there’s a common question: Can aircraft seats serve as an alternative to life jackets for flotation? The answer lies in understanding their respective functions.
While seat cushions can provide some buoyancy in water, they are not intended nor certified to function as life jackets. Their primary purpose is to offer cushioning for passengers during flight. On the other hand, life jackets are meticulously engineered to keep individuals afloat in water, equipped with buoyancy materials, secure straps, and reflective elements for visibility. They offer numerous advantages over mere cushions.
While a seat cushion might offer temporary assistance in staying afloat, it’s not a dependable substitute for a proper life jacket during an emergency. It’s crucial to utilize approved safety equipment when near bodies of water. A life jacket, designed to keep a person buoyant for extended periods, offers the rigidity needed for prolonged flotation and allows for easy movement of the arms to navigate effectively.
What fabric is used in aircraft seats?
Seats are meticulously designed to fulfill multiple purposes, ensuring passenger comfort, safety, and protection from unforeseen circumstances like fires and accidents. A typical design incorporates an aluminum frame with blocks of polyurethane foam affixed to it. Additionally, a layer of fire-resistant fabric, such as Kevlar or Nomex, is often applied over this framework, topped with a layer of cloth or leather.
Leather seats, while luxurious, are more expensive compared to traditional cloth seats. The majority of fabrics used in seat upholstery contain at least 90% wool fiber, with the remainder typically consisting of polyamide (nylon). Wool stands out as the primary fiber chosen for commercial airline seating fabric due to its desirable properties and suitability for such applications.
What is the lightest economy seat?
In recent times, airlines have been downsizing seat dimensions to accommodate more passengers, resulting in reduced cushion length and leg space. This contrasts with earlier times when airlines offered more generously cushioned seats and ample amenities.
According to Recaro Seats Company, their SL3710 model represents the lightest economy class seat available, weighing in at a mere 8 kg (17.6 lb.), setting a new standard in aircraft seating.
For individuals weighing more than 350 pounds, fitting into a standard economy-class seat can be a challenge due to the narrower dimensions. Economy seats, also referred to as “coach,” “standard,” or “main cabin” seats, typically range from about 40 to 48 centimeters in width, further emphasizing the need for more accommodating seating options.
