Pilot error, structural failure percentages

Pilot error, structural failure percentages

Pilot error, structural failure percentages

(OP)
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!

RE: Pilot error, structural failure percentages

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
