Analysis

The pilot reported that on initial climb at an alt of 300 ft AGL, engine power began to decay. A right turn was initiated to return to the runway but a further loss of power was experienced and a forced landing was attempted in a field. The acft contacted trees and came to rest in a wooded area on the arpt property. Post accident inspection revealed that the throttle cable came loose at the throttle lever inside the cockpit. The carburetor was not spring loaded to keep the throttle at full power. This was the maiden flt of the homebuilt/experimental acft.
