Incident Details
A certified flight instructor (CFI) was administering a biennial flight review to a private pilot. The flight began with maneuvers at the practice area, after which they returned to the departure airport. The aircraft executed a touch-and-go landing and takeoff.
Loss of Engine Power
Following the initial landing, the private pilot closed the carburetor heat and applied full power. When the airplane reached approximately 100 feet above the ground, the engine began to sputter and lose power.
Emergency Maneuver
The CFI assumed control of the airplane and landed on the remaining runway. During the landing roll, the CFI intentionally ground looped the airplane to prevent it from colliding with a ditch at the departure end of the runway. As a result of the ground loop, the airplane collided with two vehicles.
Investigation
The investigation found no evidence of any preexisting engine malfunctions or failures. The meteorological conditions were conducive to carburetor icing.
