ALTAMONT PASS -- The pilot of a fan-powered parasail was not electrocuted but fell about 50 feet to the ground when his ultralight aircraft ran into a power line near a major PG&E substation Saturday afternoon, authorities said.

The unidentified man was taken to a Manteca hospital, according to Alameda County Sheriff Sgt. Ray Kelly, but his condition was not immediately known. The craft itself apparently received a jolt of electricity as the wires came in contact.

The crash was reported just before noon Saturday near Midway and Patterson Pass roads, about two miles south of the Interstate 580 and 205 junction, Kelly said. A person who saw the craft go down in the remote area called authorities and led a California Highway Patrol officer to the scene.

The hills in the area are dotted with dozens of wind turbines, which feed the substation and provide power to several East Bay communities. A PG&E spokeswoman said that no disruptions to service were reported after the crash.

It was not known if the craft was a wheeled cart-style parasail, or a smaller kit that pilots can strap to their back. Kelly said that ultralight craft like parasails are subject to different regulations than actual airplanes, so the pilot may have taken off from a field or other open location.

The sheriff's department has already notified the Federal Aviation Administration and the National Transportation Safety Board of the incident, Kelly said.
