In a statement on Sunday afternoon, the City of Calabasas said it heard the news "with great sadness".
"The aircraft went down in a remote field off Las Virgenes around 10:00 this morning. Nobody on the ground was hurt," it added.
Investigators are still trying to find out the cause of the crash. But conditions were foggy, and local police had grounded their helicopters due to the poor weather.
Kurt Deetz, who has flown helicopters carrying Bryant in the past, told the Los Angeles Times that weather was a more likely cause of the accident than a mechanical issue.
"The likelihood of a catastrophic twin engine failure on that aircraft – it just doesn't happen," he said.
