NTSB Identification: GAA16CA162
14 CFR Part 91: General Aviation
Accident occurred Saturday, March 26, 2016 in Homestead, FL
Probable Cause Approval Date: 06/01/2016
Aircraft: PIPER PA24, registration: N55UA
Injuries: 1 Uninjured.

NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

The pilot reported that he shut down the engine to reposition the airplane prior to finishing the run-up. Upon attempting to restart the engine, the airplane's battery charge was low and the engine would not start. The pilot further reported that he set the parking brake, and hand propped the engine. The airplane's engine started and the airplane began to move without the pilot on board. The airplane impacted the airport's perimeter fence, which resulted in substantial damage to both wings. 

According to the pilot there were no preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:

The pilots decision to hand prop the airplane's engine without securing the airplane, resulting a runaway airplane and collision with a fence.
