Please write crashed/made percentage (crashed percent of the made planes). Which plane percentage is biggest?

again, I don't think you could derive any meaning from such statistics, even if I had them. You would need to factor things such as

number of flight hours
number of rotations (take off/landings)
age

and there are probably more factors to consider as well. Can anyone eloborate?

How about the TU-144 - nine made - two crashed - that's a 22% build/destroy ratio!!!

That must be the top of the list!

Or how about the Hindenburg? 100% build/destroy rate.

Sorry just thought I would add some humor to the situation.



DLMD-11.

777x is right, we need more specific parameters. As an example, one could argue that the 727 is more dangerous than the MD-11 because it has had more crashes. But, when you factor in the fact that about 1600 more 727's were built than MD-11s, and that the 727 was in service for 26 years when the MD-11 came out, I could probably turn that around and say that flight for flight, the MD-11 is FAR riskier than the 727....
Isn't it interesting how data like that can be misinterpreted if some of the parameters are missing?

Seriously, I think this title goes to the experimental XB-70 Valkyrie bomber made by North American. Two made, one crashed - 50%! (but it wasn't the fault of the design)

Sonic... perhaps you could tell us why you want to know this? After all - wouldn't you still fly on just about anything (even the TU - 124) if you had the %s?

Somewhere on one of the other aviation pages, I remember seeing a chart that showed passenger fatailities per million passenger miles for each model jetliner. I think this would be the most telling of all statistics. I do remember that when I read this chart, the MD80 had the best record of all. I looked for the chart today but couldn't find it. If I do, I'll post the url.

The website that Wannabe is talking about is http://www.airsafe.com

According to their stats, the safest aircraft in the world is the Saab 340 turboprop (surprising, being a small aircraft and all) with 0.33 fatal events per million flights (3 events in 9 million + flights).

The safest jet aircraft is the Boeing/MD-80 with a rate of .40 fatal events per million filghts (8 events in 20 million flights). YES. THE MD-80 THAT IS SUPPOSEDLY UNAIRWORTHY. Perhaps we should deliver this information to all the idiots who are calling for the MD-80s to be grounded or even scrapped.

Other safe jets:
Boeing 737-3/4/500: 0.41
Boeing 0.46
Boeing 757: 0.56
Boeing 727: 0.66
Airbus A320: 0.67

The worst rate of current aircraft (out of bad luck if you ask me) is the Boeing/MD-11 with a rate of 4.29 fatal events per million flights (3 events in only 0.7 million flights mind you). That number will drop in the future.

Other jets that didn't fare well:
Fokker F.28: 2.35
Boeing/DC10: 1.97
Airbus A310: 1.85
Boeing 747: 1.55
Airbus A300: 1.0

Whoops, where I put Boeing 0.46 I meant:

Boeing 767: 0.46
