County firefighters battling a roughly one-acre brush fire in Malibu Creek State Park found the smoldering remains of a crashed airplane in the midst of the burn area, and a sheriff's spokesman said the crash appears to be connected to a hard landing made by another small plane on golf course about five miles away. The brush fire was reported shortly after 2 p.m. in heavy brush at Mulholland Highway at Las Virgenes Road, according to the county Fire Department. While putting out the fire, crews spotted debris along the hillside and discovered it was a crashed small airplane. Fire crews began scouring the hillsides in search of potential victims, but as of late afternoon, there was no word on whether any victims or survivors had been found.Meanwhile, at about 2:10 p.m., fire crews responded to the Westlake Village Golf Course, 4800 Lakeview Canyon Road, for a single-engine Cessna airplane that made a hard landing on the course, according to county fire Inspector Tony Imbrenda. Three people were treated for minor injuries. Initial reports indicated that the plane was brought down by a bird strike. But Steve Whitmore, spokesman for the Los Angeles County Sheriff's Department, told NBC4 the Malibu crash and Westlake hard landing ``appear to be connected,'' although it was too early in the investigation to determine exactly what happened.Whitmore said the final determination will be made by National Transportation Safety Board investigators, who were expected to be on scene Tuesday.The plane that landed on the golf course bore markings of American Flyers, a pilot-training school based at Santa Monica Airport. The plane that crashed in Malibu was burned beyond recognition.
