Analysis

Shortly after takeoff, the engine suddenly lost power. The pilot initiated an emergency landing off the end of the runway. During the landing roll, the airplane collided with the high vegetation damaging the right wing, landing gear, and fuselage. The engine was torn down and inspected. No mechanical failures or malfunctions were found. Weather conditions were temperature 60 degs, dewpoint 40 degs.
