On February 13, 2013, about 1430 central standard time, a Piper PA46-500TP, N32CA, rolled forward and struck a building after the engine was started. The airplane sustained substantial damage to a wing. The pilot was uninjured. The airplane was registered to Croft Aviation LLC and was operated by the pilot under 14 Code of Federal Regulations Part 91. Visual meteorological conditions prevailed for the flight that was destined to Centennial Airport, Denver, Colorado. The flight was originating at the time of the accident.A fixed base operator (FBO) employee stated that he was standing in front of the airplane waiting for it to start. The airplane started and about a minute later, it began to move forward. As the airplane was moving forward, the employee signaled the pilot to move straight ahead. After the airplane moved about 13 feet, the employee signaled the pilot to turn right. To the employee's "shock," the airplane continued forward and into a grass area with the propeller at "high speed." The employee ran and turned around to see the airplane impact a rock pier at a building. The propeller flung pieces of stone. The left wing was "pouring" out fuel.

The pilot stated that the airplane was on the ramp facing a building. Upon engine start, the airplane moved forward with pressure on both toe brakes. The brakes were pumped several times before they began to slow the airplane but did not stop the airplane before it impacted building.

A Federal Aviation Administration inspector stated that he was able to stop the airplane and a tow vehicle while the airplane was being towed. Examination of the brake system revealed no anomalies that would have precluded normal operation.
