Analysis

The plt rprtd that after reaching cruise alt, the eng began to run rough & subsequently lost power. He made an emerg landing in a dry cultivated field. Drg the landing, the gear collapsed & the acft was substantially damaged. The fuel tank was equipped with a weighted 'flop' tube for aerobatic flt. The flop tube was kinked, but there was evidence the kink occurred drg the crash landing. Also, there was 4.5 ft of exposed & uninsulated fuel line forward of the firewall. Before the flt, the 'heat soaked' eng was difficult to start with an air temp of 85 deg, possibly from vapor lock.
