Probable cause
The fracture of the upper-left tail boom attachment bolt due to abnormal loading of the bolt caused by a gap and misalignment between the upper-left longeron and the tail boom. Contributing to this incident was the lack of a check to verify the absence of gaps or misalignments at the conclusion of installation for the upper-left longeron.
