Federal investigators were sifting through evidence Sunday at the scene of a fatal plane crash at Lee Gilmer Memorial Airport in Gainesville. A preliminary report could be issued in about 10 days, said Keith Holloway, spokesman for the National Transportation Safety Board. A more complete report — one that gives possible causes of the crash — could be released in 12-18 months, he said. “It’s more about fact-gathering and collecting all the perishable evidence at this point,” Holloway said. “The aircraft will be moved to (another) facility for further examination if necessary.” Robert Carlisle Alberhasky, 68, of Cumming died after his 2015 Lancair International Legacy RG crashed Saturday, Nov. 17. Alberhasky is believed to have been the pilot, Gainesville police spokesman Sgt. Kevin Holbrook said.
