On August 24, 2016, about 1830 central daylight time, a Beech E-55, N855T, impacted the runway surface during a gear-up landing on runway 17 at Sheppard Air Force Base/Wichita Falls Municipal Airport (SPS), Wichita Falls, Texas. The airplane sustained substantial damage to the bottom fuselage structure. The flight instructor and a student pilot were uninjured. The airplane was registered to and operated by Cobra Kai Inc under 14 Code of Federal Regulations Part 141 as an instructional flight that was operating on an instrument flight rules flight plan. Visual meteorological conditions prevailed at the time of the accident. The flight last departed from Lawton-Fort Sill Regional Airport (LAW), Lawton, Oklahoma and was destined to SPS.
Examination of the main landing gear retraction actuator assembly revealed a broken snap ring within the manual crank extension housing that allowed the actuator worm gear to reposition itself beyond the actuator worm sector travel limits.
