What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Aircraft experienced inflight breakup while supporting military training manuevers. Right wing separated from aircraft and was found approximately one quarter mile from impact site. Aircraft had been recalled to return to base due to declining weather conditions at the time. Last aircraft report was 4 miles from base, accident site was approximately 3 miles from base. NTSB laboratory metalurgy report states that all fractures were consistent with overstress separations with no evidence of preexisting cracking. The overstress fractures were consistent with deformation and fracturing in the caps of the main spar indicated significant upward bending in the wing.
