P248 262
Instead of blaming an airline accident on pilot error, investigators should find out why the error was made by analyzing airplane design, airline management, and pilot-training programs. For only then can changes be made to ensure that the same type of error does not recur and cause another accident.
(D) Investigators of airline accidents should contribute to the prevention of future accidents.
(A) Pilot error is not a contributing factor in most airline accidents
能帮我分析一下这道题吗？conclusion 和evidence各是什么？答案为何是D？A为何不对？

what is the question of this problem?

if it asks the main point, then D is the right one, for it is said that we should investigate many factors to ensure that the same type of error does not recur and cause another accident rather than blame the pilot for the error.  

by the way, we cannot judge from the passage that the pilot error is not a contributing factor in most airline accidents.
