The pilot in a retractable landing gear Beech C90, accompanied by a company check pilot, reported that they were conducting a training flight in preparation for a Title 14 CFR Part 135 check ride.
During a no-flap landing, as the airplane crossed the runway threshold at the airport in Montague, California, the pilot set the airplane power to idle, and an aural warning sounded, which indicated the landing gear was retracted.
The airplane landed with the landing gear retracted. The airplane sustained substantial damage to the lower fuselage.
The pilots reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
Probable cause: The failure of pilot to extend the landing gear during landing.
