Overview
- The Greg Biffle estate filed a motion to dismiss the wrongful-death lawsuit brought by the estates of Dennis and Jack Dutton on Sept. 22, 2026 and argues the Duttons were negligent in how they operated the Cessna Citation 550.
- The Dutton estates had earlier sued the Biffle estate seeking about $15 million each, alleging Biffle or his companies bore responsibility for the jet’s maintenance, operation and safety.
- The NTSB’s preliminary report recorded mechanical and electrical problems discussed during the flight, said Dennis Dutton was flying with his son Jack sharing some control duties, and noted a required qualified second-in-command was not present, but the board has not issued a final probable-cause determination.
- Greg Biffle’s ex-wife Nicole Biffle filed a separate wrongful-death suit on behalf of their daughter and later sought $10 million and a court order to freeze estate distributions pending resolution of claims.
- With opposing allegations now front and center in state court, judges will weigh procedural defenses and civil fault while any final NTSB finding may inform but will not decide who is legally liable, leaving potential payouts that could reach into the tens of millions of dollars.
