## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

AIRCRAFT EXPERIENCED ENGINE FAILURE MADE EMERGENCY LANDING IN A VINEYARD. (.4)THE AIRCRAFT WAS OWNED AND OPERATED BY THE PILOT AND WAS ON A LOCAL INSTRUCTIONAL FLIGHT TO COMPLETE THE PILOT'S BIENNIAL FLIGHT REVIEW. THE PILOT AND INSTRUCTOR REPORTED THAT THEY WERE PERFORMING A SERIES OF SLOW FLIGHT MANEUVERS AND STALLS. THE ENGINE LOST POWER AND COULD NOT BE RESTARTED, AND THE PILOTS WERE FORCED TO LAND IN A VINEYARD. ON-GROUND COLLISION WITH GRAPE VINES AND THE SUPPORTING WOODEN POSTS AND WIRES DAMAGED THE AIRCRAFT. AN FAA INSPECTOR REPORTED THAT ROTATION OF THE CRANKSHAFT PRODUCED COMPRESSION IN EACH CYLINDER, WITH ACCESSORY GEAR AND VALVE TRAIN CONTINUITY ESTABLISHED. THE CARBURETOR AND FUEL SYSTEM WERE EXAMINED, WITH NO ABNORMALITY NOTED. BOTH MAGNETOS SPARKED WITH HAND ROTATION. ABOUT 13 MILES WEST AT UKIAH, CALIFORNIA, THE 0845 WEATHER OBSERVATION SHOWED THAT THE TEMPERATURE AND DEW POINT WERE 60 AND 51 DEGREES FAHRENHEIT. REVIEW OF A CARBURETOR ICING PROBABILITY CHART REVEALED THAT THE TEMPERATURE AND DEW POINT WERE WITHIN AN AREA OF THE GRAPH ANNOTATED 'SERIOUS ICING - CRUISE OR CLIMB POWER.'
