Analysis

On initial climb after takeoff, plt noted a loss of climb performance, executed steep 180 degree turn to avoid high voltage lines on rising terrain ahead. This maneuver, coupled with reduced power resulted in an airspeed decrease to near stall speed. Plt lowered the nose to prevent stall, collided with tree tops and lost flying speed. Plt managed to keep acft upright during ensuing mush into open field but gear collapsed on touchdown due to high descent rate. Investigation revealed inner flame tube in muffler had dislodged, partially blocking exhaust outlet and resulting in excessive engine back pressure.
