The estates of a father and son who died alongside former NASCAR driver Greg Biffle in a December 2025 plane crash have filed wrongful death lawsuits seeking $30 million, alleging Biffle failed to properly maintain the aircraft he owned.
The suits, filed in Iredell County, North Carolina, target Biffle's estate on behalf of pilot Dennis Dutton and his son Jack, who were among seven people killed when a Cessna Citation II crashed shortly after takeoff from Statesville Regional Airport on December 18, 2025. The Sun first reported on the filing and the allegations at its center: that Biffle, as the plane's owner, bore responsibility for what the Dutton family's lawyers call "inadequate maintenance and upkeep" of the jet.
The core claim is straightforward. Biffle owned the Cessna C550. The Dutton family contends he was negligent in maintaining it. Breitbart reported that cockpit voice recorder data suggests the crew noticed thrust problems during takeoff, before the aircraft went down.
That detail matters because it ties the alleged maintenance failures to a specific, observable malfunction in the moments before impact. If the thrust issues trace back to deferred maintenance or overlooked mechanical defects, the negligence theory gains traction. If they trace to something else entirely, the case becomes harder to prove.
Investigators will need to determine exactly what caused the thrust anomaly and whether it resulted from the aircraft's maintenance history or from some other mechanical or operational factor.
The wrongful death suits land against a backdrop of troubling preliminary findings from the National Transportation Safety Board. The New York Post reported that NTSB investigators determined Biffle was not piloting the jet when it crashed. The person occupying the right seat, the copilot position, was not qualified to serve in that role on the aircraft.
That finding carries weight. The Cessna C550 requires two trained pilots. Having an unqualified person in the copilot seat during an emergency is the kind of gap that can turn a recoverable problem into a fatal one.
Aviation safety consultant Jeff Guzzetti put it bluntly:
"This airplane requires two trained pilots, and if things go wrong and you don't have a trained pilot, then bad things can happen."
The crew reported gauge and instrument malfunctions shortly after takeoff and attempted to return to the airport. The jet crashed and caught fire before it could land. All seven people on board died, including Biffle, his wife, two of his children, and the Duttons.
The lawsuits and the NTSB investigation are pulling at different threads of the same disaster. The Dutton family's legal theory focuses on maintenance. The federal investigation has so far highlighted crew qualification and instrument failures. Whether those threads converge or point in separate directions will shape both the litigation and the final accident report.
Authorities have not publicly confirmed whether the unqualified copilot played any role in the crew's inability to recover from the takeoff emergency. Investigators also have not said whether the instrument malfunctions and the thrust problems were related or independent failures.
The distinction matters for the lawsuit. If the crash resulted primarily from having an unqualified copilot rather than from mechanical neglect, the negligence claim against Biffle's estate becomes more complicated. The Dutton family's attorneys will likely need to show that maintenance failures were a proximate cause of the crash, not just a background condition.
The FAA's recent enforcement actions against major airlines over safety compliance failures underscore how seriously federal regulators treat maintenance and operational standards in aviation. Private aircraft owners face their own set of obligations, and those obligations do not shrink just because the plane is not part of a commercial fleet.
Dennis Dutton was the pilot. His son Jack was on board as well. The family's $30 million claim reflects not just the loss of two lives but the allegation that those lives were lost because someone else cut corners.
Wrongful death suits in North Carolina allow surviving family members to recover damages for the full value of the decedent's life, including lost income, companionship, and the pain and suffering of the deceased in the moments before death. With two family members killed in the same crash, the Dutton estate's exposure calculation reaches into territory that will demand serious attention from Biffle's estate and its insurers.
No public results have been released about the aircraft's full maintenance records or whether any specific inspections were missed or deferred. That information will almost certainly surface during discovery if the case proceeds to litigation.
The crash has already generated legal and investigative fallout beyond the Dutton family's claims. Investigators have said that associates of Biffle launched a coordinated scheme to steal from him in the hours after the crash, adding a layer of alleged opportunism to an already grim story.
The lawsuits are in their early stages. Biffle's estate has not publicly responded to the allegations. The NTSB's final report, which typically takes 12 to 24 months after a crash, has not been released. That report will carry enormous weight in any courtroom proceeding because it will assign probable cause to the accident.
If the NTSB concludes that maintenance failures contributed to the crash, the Dutton family's case strengthens considerably. If the board points instead to crew error or the unqualified copilot as the primary cause, the estate's defense team will have a powerful counter-argument.
Either way, the families of all seven victims are watching. The Duttons filed first, but they may not be the last. Wrongful death litigation often becomes a proving ground for competing narratives about who bears responsibility when someone dies under disputed circumstances.
The legal system will ultimately have to sort through the maintenance records, the cockpit voice data, and the NTSB findings to determine whether Biffle's estate owes the Dutton family $30 million or whether the cause of this crash lies somewhere else entirely.
High-profile deaths often attract complex legal disputes over money and accountability, and this case is no exception. The question is whether the courts can deliver clarity before the public narrative hardens around assumptions that may or may not survive contact with the evidence.
Seven people boarded that plane. None of them walked away. Someone owes their families an answer, and the courtroom in Iredell County is now the place where that answer will be tested.
