Accident Investigation Board results will be available in the future. SIBs are completed first, then the AIB convenes to assign blame/fault.
SIBs are restricted for educational use only to prevent future mishaps. Sometimes, SIBs contain info or research which if got out could make manufacturers or other companies involved liable. In order for them to cooperate, they must have the assurance that the results will not be made public/cause them legal troubles. Most companies (no first hand experience) will work with the SIB then STFU when the AIB comes a knockin'.
