Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Analysis

Witnesses reported seeing the aircraft performing aerobatic maneuvers at approximately 1500 feet. The aircraft was later found with the tail surfaces separated. The tail surfaces were found 300 and 400 feet from the main wreckage. A metallurgical examination of the attach points for the tail surfaces revealed all failures to be from overstress. According to available records, the pilot had very little aerobatic training and experience.
