Ignition system,spark plug - contaminationCause
Engine assembly,cylinder - low compressionCause
Engine assembly,piston - wornCause
Engine assembly,valve,intake - movement restrictedCause
Maintenance - inadequateOther maintenance personnelCause
Fluid,fuel grade - improperFactor
Operation with known deficiencies in equipment - intentionalPilot in commandCause
Forced landingDescent - emergency
In flight collision with terrain/waterLanding - flare/touchdown

Analysis

The plt reported that on his preflight he found the eng compression & oil level to be low but after servicing the oil to the proper level he departed & on initial climb, after reaching about 100 ft AGL, the eng started popping & losing RPM. The plt made a left turn to avoid obstacles & landed in a small grape vineyard. Post crash examination of the eng revealed low compression & excessive oil consumption due to wear. The acft had been operated with automotive fuel.
