Accident Overview
A certified flight instructor (CFI), a student pilot (SP), and two passengers departed on a local training flight in a 150-horsepower airplane. The flight included upper airwork, followed by practice landings into the wind at one airport, before attempting crosswind landings at the departure airport.
Approach and Landing
The SP flew the first approach. On short final to runway 20, the left wing dropped. The CFI took over control at an altitude between 8 and 12 feet. The airplane landed hard, causing the main landing gear to separate, and the airplane subsequently ground looped.
Pilot Experience and Aircraft Loading
The SP had a total of 20 hours of flight time and had not flown in the preceding 90 days. Additionally, the SP had no previous experience in the accident make and model. The airplane was calculated to be 46 pounds over the maximum gross weight at the initial takeoff. At the time of the accident, the airplane was 25 pounds under the maximum weight, with the center of gravity about 1 inch forward of the aft limit. The calculated density altitude was approximately 2,600 feet.
Weather Conditions
Winds reported at a nearby airport were from 180 degrees at 20 knots, gusting to 26 knots.
