Probable cause

The inadequate design by the airplane manufacturer for using bolts to secure the inboard trailing edge flap that are susceptible to stress corrosion cracking. Also, the stress corrosion cracking failure of the four H-11 bolts that secure the left inboard trailing edge flap to the outboard hinge which allowed the separation of the flap and vane while on final approach.
