Examination of the empennage and aft fuselage revealed that the middle portion of leading edge of the vertical fin sustained a heavy impact from debris from the right hand side of fuselage that likely was associated with the upper portion of the vertical fin separating. Some stringer fragments of section 46 were found stuck in the right side of vertical fin. The lower portion of the fin (item 630C1), the upper portion of the fin (item 2035), and several of the floating pieces (item 22) show similar evidence of impact damage on the right side. The entire empennage separated from section 46 at STA 2360 resulting from a combination of impact by fuselage debris and insufficient remaining structure of section 46 to support the weight and loads of the empennage.
