Analysis

A private pilot check ride was interrupted by a forced landing on a golf course after having experienced severe vibrations and a loss of power. During the forced landing the acft collided with a 10 ft tall tree and nosed down to terrain impact. Investigation revealed that the #3 cylinder had separated from the eng. The large diameter cylinder hold down studs separated in overload, but the lower small diameter studs were intact, indicating that the cylinder hold down nuts had backed off.
