Details:
A small plane crashed into a mansion and burst into flames yesterday, killing the lead guitarist of the Ozzy Osbourne rock group and two other people who were aboard, police said.
  The plane twice buzzed the house, where the rock group was staying, and on a third pass clipped the rock group's tour bus and a tree, then slammed into the two-story colonial home, officials said. Killed were guitarist Randall Rhoads, 25, pilot Andrew Aycock, 36, and Rachel Youngblood, 58, the group's makeup artist and hairdresser, said Lake County Deputy Sheriff Mike Smalt.
  Osbourne - known for such stage antics as biting off the head of a live bat - was in the bus but was not hurt, Smalt said. Several other group members escaped unhurt from the mansion before it was gutted by flaming gasoline that spewed from the Beechcraft Bonanza, officials said.
  Rhoads and Youngblood were from Los Angeles, Smalt said. He said Aycock lived at Flying Baron Estates, the wealthy, private airport community about three miles east of Leesburg where the crash occurred. The group was staying at the mansion before a concert scheduled for Orlando on Saturday. Members of the group quickly left the crash site and it was not known whether they would perform.
  Jack Barker, Atlanta regional spokesman for the Federal Aviation Administration, said the FAA flew an investigator to the scene yesterday. He said the National Transportation Safety Board also would investigate. The bus - outfitted with plush chairs, video games and a stereo system - was punctured by the wing of the aircraft.
