CEN10LA136

The private pilot was returning from a short personal flight when the engine stopped producing power. The pilot was unable to maintain altitude and landed short of the runway and flipped over. The engine was test run using the airplane's existing fuel system. The engine started and ran through its entire powerband without hesitation. A functional test of the carburetor heat and both magnetos were normal, and all engine gauges indicated normal readings. No mechanical deficiencies were noted with the engine or the fuel system. The cause of the power loss could not be determined.

On February 14, 2010, at 1600 central standard time, N56347, a Maule M-5-235C, sustained substantial damage after a loss of engine power while returning to land at La Porte Municipal Airport (T41), La Porte, Texas.

The run was conducted using the airplane's existing fuel system. The engine started and ran through its entire powerband without hesitation. A functional test of the carburetor heat and both magnetos were normal, and all engine gauges indicated normal readings. No mechanical deficiencies were noted with the engine or the fuel system.
