Incident Overview
A certified flight instructor (CFI) was demonstrating a power-off spot landing to a dual student, who held a commercial pilot certificate and was observing the maneuver. The CFI made an initial attempt at the landing, but executed a go-around because the airplane would not have reached the runway.
Second Attempt and Outcome
On the second attempt, the CFI aimed for the 1,000-foot runway markings but realized the airplane would not reach them. However, he believed it would reach the runway surface. When the airplane was approximately 30 feet from the runway end and 10 feet above the ground, the CFI began adding engine power. The airplane then "dropped into the sod."
Structural Damage
The impact caused the left landing gear to separate from the wing, and the left wing subsequently separated from the fuselage. The CFI reported no mechanical failures or malfunctions with the aircraft.
