On January 2, 2014, about 1700 central standard time, a Bell 206B helicopter, N400XL, experienced a roll over while repositioning from the ramp to a mobile helipad. The pilot was not injured. The helicopter was registered to and operated by Engemann Aviation Services, LLC under the provisions of 14 Code of Federal Regulations Part 91 as a personal flight. Visual meteorological conditions prevailed for the flight, which originated from Draughon-Miller Central Texas Regional Airport (KTPL) in Temple, Texas.

The pilot reported he was relocating the helicopter from the parking ramp to a mobile helipad approximately 30 feet away. As the pilot lowered the helicopter onto the mobile helipad, the left rear skid slipped off the pad. The helicopter rolled over and impacted the ground on its right side. The rollover resulted in substantial damage to the main rotor head, including separation of the rotor blades, and separation of the tail boom.
