At about 0700 local time, the Piper Seminole collided with terrain. The CFI, a certificated Private pilot receiving instruction and one passenger sustained fatal injuries; the airplane was destroyed. Maneuvers scheduled for the flight included power-on and -off stalls, slow-flight maneuvering, engine shutdown and feathering procedures, single-engine maneuvering and a Vmc demonstration, as well as approaches and landings. Witnesses reported that they saw the airplane rotating as it descended. One witness described its descent as a falling leaf. The operating arms of both main gear actuators were extended, which the airframe manufacturers representative said corresponded to the gear-down position. All major components of the airplane were located at the accident site.
