Analysis

After takeoff the acft was observed to climb to about 7,000-8,000 ft MSL & enter a slow flat spin. 8 turns were counted & the acft did not recover. The plt bailed out of the acft at about 500-600 ft but the parachute did not have time to fully deploy. The right horizontal stabilizer & elevator had broken loose & only fabric held it to the empennage. Both the forward & rear spars were broken at a point where the attaching bolts go through the spars. The forward spar was 1/2 inch thick & drilled with a 1/4 inch drill to accommodate the 1/4 inch mounting bolt. The hole was not centered in the spar & the hole had run out the side of the spar. The rear spar was 1 inch thick & the 1/4 inch hole was also drilled off-center.
