The Aaxico Curtiss C-46 was flying en route near Abilene when elevator control was lost. An emergency was declared and the crew carried out a GCA assisted emergency approach to Dyess AFB using power and trim for pitch control. The aircraft touched down safely but started to porpoise. The crew applied full power and the aircraft climbed steeply to a height of 150-200 feet. The plane then stalled, pitched down and crashed on the runway at an angle exceeding 45 degrees.

Probable Cause:

PROBABLE CAUSE: "The Board determines that the probable cause of this accident was loss of elevator control because of an improperly secured bolt, a condition which was undetected because of an inadequate inspection."
