Pilot error, structural failure percentages 1

[inertia4u]

I just came across a short entry in Aviation Week's "The Weekly of Business Aviation" which states that pilot error can account for up to 80% of all fatal accidents involving aircraft. My question is, what constitutes the other 20%? Does anyone know the break down percentage wise? For example; Weather accounts for X%, structural failure for y%, system failure z%. Any info would be appreciated.

Thanks! -----

Hi,
Regarding the causes of civil aviation accidents the following information comes from a paper presented at the 1991 ICAF Conference by A.J. Emmerson (Safety Regulation and Standards Division, Civil Aviation Authority of Australia)and refers specifically to wide-body airliner accidents before 1986.
Aircraft design, manufacture and maintenance 39%
Flight crew error 23%
Weather 23%
Ground crew error 4%
Air traffic control 4%
Passenger error 3%
Cabin crew error 2%
Bird strike 2%
Other 1%
(Figures do not add exactly to 100% due to round-off)

The information is based on research by Wiegers and Rosman: "Safety Information System - A safety profile of Wide-body Commercial Aircraft", Flight Safety Foundation Air Safety seminar, Proceedings 39th Annual Meeting, October 1986.
I hope this is of use to you.
Regards
Andries
