Probable cause

The separation of the right wing’s forward lift strut from the fuselage due to a missing nylon-insert lock nut. Contributing to the accident was the noncertificated pilot’s decision to operate the airplane even though a condition inspection had not been completed in the 13 years since the airplane received its experimental airworthiness certificate.
