Analysis

The aircraft sustained an in-flight breakup during the enroute phase of the flight. The left fitting that secures the front spars of the stabilizers to the fuselage revealed the presence of pre-existing fatigue cracking. The initial separation of the left stabilizer was indicative of an upward failure, with the initial separation in the front spar. The pilot was a certified A&P mechanic. No pilot or aircraft logs were recovered. No evidence was found indicating maintenance being performed by persons other than the pilot.
