Accident Reports
International commercial air travel has reached levels of safety and convenience which would have been unimaginable just a generation ago. Although almost always extremely tragic events, the lessons from accidents have played an important role in the process to continue improving aviation safety.
Accident Rates
US/Canadian Operators Accident Rates by Year
The cleverest trick by someone arguing a point without facts is to use a twist of statistics to prove a point. Here is where we find accident rates and the claim pilots are letting the world down by not holding their end of the man/machine equation. Look at the chart above, accident rates have plummeted. (True). Look at the chart below, accidents caused by pilots are way up! (Not true.)
The percentage of accidents caused by pilots is indeed up. But the number is down, even in the face of many more flights, many more airplanes, and many more pilots.
None of this is to excuse pilot error as a cause of accidents. We should continue to strive for improvement. But don't let the faux statisticians make you think it is a lost cause. It isn't.

The big picture falling accident rates (on the top of the page) leads one to believe we have this aviation thing figured out. The decline has been so sharp that it is undeniable that things have gotten better. While a lot of that is because we are smarter, most of it is because we are smarter at building airplanes.
An ICAO study notes that the proportion of accidents caused by humans is way up. Of course this is statistical hocus pocus. While the number of accidents has gone down, the number caused by mechanical problems has gone way down. Human issues have no place to go but up. I would argue that we as pilots have made great strides as well, but we can and should improve. |

- The accident statistics presented in this summary are confined to worldwide commercial jet airplanes that are heavier than 60,000 pounds maximum gross weight. Within that set of airplanes, there are two groups excluded:
- Airplanes manufactured in the Commonwealth of Independent States (CIS) or the Union of Soviet Socialist Republics (USSR) are excluded because of the lack of operational data; and
- Commercial airplanes operated in military service. (However, if a military-owned commercial jet transport is used for civilian commercial service, those data will be included in this summary.)
- The following airplanes are included in the statistics:
DC-8 DC-9 DC-10/MD-10 MD-11 MD-80/-90
A300 A300-600 A310 A320/321/319/318 A330 A340 A380

Situational Awareness Case Studies
[Airbus Flight Operations Note, pg. 2]
Situational awareness is not just a theoretical notion and is pertinent to most accident or incident cases. It is real, and its absence causes accidents. Research from the Australian Transportation Safety Board (ATSB) indicates that human factors is a contributing cause in around 70 percent of all incidents and accidents. Approximately 85 percent of incident reports include a mention of loss of situational awareness. Degraded situational awareness can lead to inadequate decision making and inappropriate actions. This is illustrated in [the table], which identifies causal factors involved in approach and landing accidents.
