Narrative:On May 10, 1994, at 21:42 hours PDT (Pacific Daylight Time), a Robinson R-22 Beta, N8047Y, collided with the upper static cable of power transmission lines in Hacienda Heights, California, while on a night cross-country flight. The helicopter was rented to the pilot by Skyline Aviation, Inc., Chino, California, and was being operated as a personal flight. The helicopter was destroyed by impact forces and post-impact fire. The certificated private pilot and certificated private pilot passenger received fatal injuries. The flight originated in Chino, California, at 20:00 hours PDT, destined for the Whiteman Airpark, Pacoima, California, and then was scheduled to return to Chino. The accident occurred during the return leg of the flight. Night visual meteorological conditions prevailed with visibility restricted to 4 to 6 miles due to fog and haze. The pilot left a visual flight rules flight plan with the helicopter's operator.
After the collision with the cable, the helicopter came to rest on the westbound lanes of Interstate 60. Witnesses traveling eastbound on the interstate indicated they saw the helicopter about 6 miles west of the accident site flying southeast along the interstate at a low altitude. The eastbound witnesses indicated they followed the low-flying helicopter's flight progress until they saw a flash followed by the helicopter descending uncontrolled and exploding.
Witnesses who were traveling westbound on the interstate indicated they saw the helicopter momentarily tethered by the cable before it started to descend. According to the westbound witnesses, there was electrical arcing and the helicopter exploded above their automobiles as they traveled under the helicopter. The westbound witnesses stated the helicopter exploded again when it struck the surface of the interstate, and the fire spread across several lanes as a flammable liquid spilled from the helicopter
Three automobiles were damaged when the helicopter struck the ground. One automobile stopped in the westbound lanes when the helicopter struck the ground in front of it. Another automobile struck the rear of the stopped vehicle. Another automobile in the eastbound lanes struck the helicopter's mast and was damaged as it dragged the mast down the interstate. All reported injuries on the ground were a result of automobiles colliding in the westbound lanes.
