Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that, during a flight review, while landing in gusting wind conditions, the airplane ballooned and landed hard on the left main landing gear. The airplane veered sharply to the left, and the pilot applied full power to go around, but the airplane "would not climb." The flight instructor took the flight controls and the airplane came to rest about 400 yards south of the runway. The flight instructor reported that, during the landing, the airplane ballooned and "abruptly dropped" onto the runway, damaging the left landing gear. The airplane veered to the left, the pilot applied power to go around, and the airplane bounced into the air. He added that the airplane would not climb and continued to bounce multiple times before coming to rest south of the runway. He believed the propeller and landing gear damage may have prevented the airplane from climbing during the go around. The airplane sustained substantial damage to the fuselage. The automated weather observation station located on the airport reported that, about 6 minutes before the accident, the wind was from 250° at 11 knots, gusting to 16 knots. The airplane landed on runway 27.
