Probable cause
The in-flight fracture of a stainless steel bolt that was used to secure the upper and lower wing cables to the outer attach point at the leading edge spar of the right wing due to stress corrosion cracking, which caused the right wing to fail and precluded controlled flight. Contributing to the bolt failure was the installation of a bolt that did not conform with the company's specification.
