Analysis

The helicopter was parked with the eng running when it was struck by another acft, a Beech C-45G. Prior to the collision, the helicopter was at a low RPM; therefore, the plt was unable to move the helicopter out of the way. The Beech acft was being taxied from an FBO with no intent for flt. Prior to taxiing, a mechanic had examined the brakes & told the plt of the Beech that the right main brake pads were completely worn & were in need of repair. The person taxiing the Beech lost control, while taxiing, & allowed the acft to run into the helicopter.
