Probable cause
the student pilot's excessive retraction of flaps and failure to attain an adequate airspeed during a go-around that led to a stall/mush.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The airplane landed hard on the runway during an attempted go-around, causing substantial damage. In the flare for landing the student pilot decided to do a go-around due to the effects of a wind gust. The student added full power, shut off the carburetor heat, and reduced the flaps to 10 degrees. Initially the airplane began to climb, and then "dropped and landed hard" on the runway. According to the Cessna 150L owner's manual, during a go-around, the flaps should be reduced to 20 degrees after application of full power. After a safe airspeed has been attained the flaps should be slowly retracted to the full up position.
Factual narrative
According to the student pilot the landing approach was conducted at 71 knots with full flaps, and the airplane was aligned with the centerline of runway 22. He noted the windsock was flat but pointing in a crosswind direction relative to the runway. He said that as he flared for landing, the wind picked up in the crosswind direction and turned the airplane into the wind. He corrected for the wind condition, but felt unsure of a safe landing. The student pilot initiated the go-around with the application of full throttle, turned off the carburetor heat, and retracted the flaps to 10 degrees. He stated that the airplane was climbing and then "just dropped and landed hard." The pilot reported that the AWOS was not reporting gusty wind conditions at the time, but the winds were from 230 degrees at less than 6 knots.
According to the Cessna 150L owner's manual, "in a balked landing (go-around) climb; the wing flap setting should be reduced to 20 degrees after full power is applied. Upon reaching a safe airspeed, the flaps should be slowly retracted to full up position."
