I am not sure what counts as "expert judgement", but large amounts of industrial FTA was/is based on 
stastistical-data-based reliability estimates for individual components.

The problem with FTA is/was the independence assumptions (they don't deal with common-cause failure, 
meaning here one cause for more than one "trigger" failure in the FT) in any principled way), and 
the application to systems with components whose failure rates are not very well estimable.
