The NTSB's narrative final · quoted from the NTSB record
The pilot was en route to conduct banner towing when the engine began running roughly. The pilot said the engine began to shake excessively and lose power. He felt the engine might quit and selected a nearby landfill as his emergency landing area. During the precautionary landing the airplane collided with a ditch and nosed over. A postaccident examination revealed that the number 2 cylinder head had cracked from the bottom spark plug bore to the exhaust valve seat.
