Statistical information on how many times an air accident has occurred so far

There were 1085 aviation accidents between 1950 and June 2019. Statistical data on what caused it and how the number has changed are available on PlaneCrashInfo.com , which collects aircraft accident information.

Accident statistics
http://www.planecrashinfo.com/cause.htm

In PlaneCrashInfo, the cause of the accident is roughly divided into the following five.

・Pilot : Procedure error, transition from VFR (visual flight method) to IFR (instrument flight method) , spatial disorientation, excess descent, runway runaway, fuel shortage, etc.
・Mechanical : engine failure, equipment failure, structural destruction, design defect
・Weather : turbulence, wind shear , poor visibility, lightning, etc.
Interfering : hijacking, shooting down, bombs, pilot suicide
・Others : Control mistakes, ground personnel mistakes, improper cargo loading, bird strikes, fire in flight, etc.

And as a result of PlanCrashInfo classifying accidents that occurred from January 1, 1950 to June 30, 2019, the numbers for each age are as follows. The real number is the number of occurrences, and the ratio beside it is the ratio of accidents of the cause in each age.

	1950s	1960s	1970s	1980s	1990s	2000s	2010s	total
pilot	82 (50%)	119 (53%)	112 (49%)	67 (42%)	77 (49%)	48 (50%)	28 (57%)	533 (49%)
mechanical	43 (26%)	62 (27%)	45 (19%)	36 (22%)	35 (22%)	22 (23%)	10 (21%)	253 (23%)
weather	25 (15%)	15 (7%)	22 (10%)	22 (14%)	10 (7%)	8 (8%)	5 (10%)	107 (10%)
Obstruction	6 (4%)	9 (4%)	20 (9%)	20 (12%)	13 (8%)	9 (9%)	4 (8%)	81 (8%)
Other	9 (5%)	21 (9%)	31 (13%)	16 (10%)	22 (14%)	10 (10%)	twenty four%)	111 (10%)
Total for each age	165	226	230	161	157	97	49	1085

This is a chart showing the number of accidents in the flight, included in the statistics of commercial aircraft accidents by Boeing. The numbers in the two columns above the aircraft mark are the percentage of fatal accidents above and the percentage of accidents after boarding below. The number at the bottom indicates how much of the journey will be spent on a one and a half hour flight. Before the plane took off, it was shown that 12% of the fatal accidents occurred before going to the runway, and the ratio of accidents was high at the time of takeoff and landing.

“The percentage of surviving aviation deaths when there are more than 19 passengers” is also calculated. These numbers are divided by age and are as follows:

1940s: 24%
1950s: 25%
1960s: 21%
1970s: 25%
1980s: 36%
1990s: 39%
2000s: 28%
2010s: 27%

Basically, the ratio has increased until the 1990s, whether the safety has improved with the replacement of equipment, but the number has decreased again since the 2000s.

By the way, the survival rate of passengers in the “case where the pilot intentionally landed accidentally” is 42%.
