Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The acft ran off the departure end of the rwy during a forced landing following engine failure during a touch and go landing. The nosewheel struck a mound of dirt and the acft nosed over. The acft had reached 40 ft AGL and 70 mph when the engine lost power first by running rough and then failing completely. Engine teardown revealed that the #1 cylinder exhaust valve stem broke. A worn valve stem keeper sleeve allowed the valve and stem to slide into the cylinder during ahigh power application. The piston disintegrated when the valve was swallowed. The CFI took over and landed the acft butwas unable to stop on the remaining rwy.
