Probable cause
Binding of the #2 exhaust valve (stuck valve), and failure of the pilot to maintain adequate airspeed, which resulted in an inadvertent stall. A factor related to the accident was: the failed exhaust manifold gasket.
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 plt & passenger were participating in an activity to compete in dropping paper sacks of flower in a circle on the ground at a fly-in. After the plt had just completed a low pass, witnesses noted the eng began running rough, then the acft descended & crashed. An exam of the wreckage revealed the acft had impacted in a steep descent. The prop blades were equally distorted & both blades contained rotational scuff marks. A teardown of the eng revealed the #2 cylinder had a blown exhaust manifold gasket & that its respective exhaust valve was stuck. Also, heat damage was noted on the #4 cylinder, due to escaping exhaust gases.
