So the helicopter was never used by anyone else?
From what LA media has been reporting since the accident it was for all intents and purposes his helicopter. He used it for his regular commute the way that the rest of us use our cars. They have been running a clip of him telling a reporter that the helicopter was the best way of beating SoCal traffic.

History: Mr. Bryant had often flown in the helicopter before. For much of his playing career with the Los Angeles Lakers, he commuted to home games at Staples Center by helicopter. He began calling his ride the “Mamba Chopper.”
For his final game in April 2016, he made the trip in the same S-76B that crashed on Sunday; its fuselage had been decorated for that occasion with a black snakeskin pattern and Mr. Bryant’s personal logo. A former Island Express pilot told The Los Angeles Times that the “limo-esque” helicopter was a favorite of Mr. Bryant.
The aircraft also appeared, in its more usual blue-and-white livery, in photos with other celebrities — including Lorenzo Lamas, the actor turned pilot, and the singer Ashanti — that were posted on social media in recent years.
From 2007 to 2015, the helicopter was owned by the State of Illinois, part of a fleet used to transport government officials. The state sold the helicopter at auction for $515,161, according to a state database cited by The State Journal-Register of Springfield, Ill.
