## Analysis

THE PLT REPORTED THAT HE ORIGINALLY PLANNED TO START THE ACFT ENG IN ORDER TO CHARGE THE BATTERY. THE ENG STARTED USING THE ACFT STARTER SO THE PLT DECIDED TO FLY. HE SET THE PARKING BRAKE & WITH THE ENG RUNNING AT A 'FAST IDLE', EXITED THE ACFT, INTENDING TO REMOVE THE TIE DOWN CHAINS FROM THE WINGS. THE PARKING BRAKE FAILED TO HOLD THE ACFT, IT PULLED LOOSE FROM THE TIE DOWN CHAINS ACCELERATED TO ABOUT 50 MPH & COLLIDED WITH A PARKED PIPER, N381CB, COMING TO REST AFTER IMPACTING THE AIRPORT PERIMETER FENCE.
