Greg Biffle’s ex-wife, Nicole Biffle, is suing the late NASCAR driver’s estate over the December plane crash that killed seven people, including the former couple’s daughter, Emma.
Greg, his wife Cristina and their son Ryder were killed alongside Emma and three family friends on December 18, 2025, when Greg’s Cessna 550 crashed in Charlotte, North Carolina, after suffering a mechanical issue and attempting to return to the airport.
Nicole, 50, is reportedly seeking $10 million from Greg’s estate and has asked for an order preventing the estate from making more distributions to ensure there is money left to pay her and others who filed similar suits, according to court documents obtained by Us. TMZ was first to report the lawsuit’s details.
Greg and Nicole married in 2007 and welcomed Emma in 2011. They separated in 2015.
Nicole is now alleging that Emma was sick on the day of the crash and asked not to take the trip, but that Greg insisted. She is also alleging negligence on the part of Greg and others.
An additional lawsuit, filed on behalf of victims Dennis and Jack Dutton, is asking for $30 million.
The NTSB released a preliminary report related to the crash in January, where they determined that Dennis, a retired pilot, was flying the plane with his son, Jack, serving as copilot.
The report stated that Dennis was qualified to fly the plane alongside a qualified copilot, which Jack was not. Greg was also not qualified to serve as copilot, though he had a pilot’s license.
The NTSB also concluded that Dennis was likely flying the plane at first, before temporarily handing off controls to his son, then taking them back shortly before the crash. Dennis reportedly knew the plane’s altimeter had malfunctioned and the “left side flight instruments may not have been working properly.”
“Both engines remained attached to the pylon structures and both thrust reversers were found in the stowed position,” the report revealed. “There was no evidence of uncontained engine failure with either engine.”
During the attempted landing, the plane struck trees and light stanchions outside the airport before crashing through a fence.
That’s consistent with 911 audio obtained by TMZ in January. In one call, a witness reported, “We just have a plane fly over our heads and crash into the tree line.”
Though the preliminary report attempted to answer many questions surrounding what happened, former military pilot Dan Rose exclusively told Us in December that the full report was still likely a long way off.
“I would say the default from the [National Transportation Safety Board] is probably close to two years with a final report coming out,” he said. “The NTSB is pretty good about getting out what’s called a preliminary report in the first few weeks. But it’s very cursory, generally.”
