The pilot in the retractable landing gear-equipped airplane reported that about 700 ft agl, he initiated a descending right turn for landing. The pilot attempted to lower the landing gear however, the landing gear would not extend even after troubleshooting the problem. The pilot recalled that the mixture was rich, the propeller was set to maximum rpm, and full throttle was applied when he aborted the landing, but there was no corresponding response from the engine. The propeller began to windmill, and he attempted to troubleshoot the total loss of engine power by moving the fuel selector from the right tank position to the left tank position and engaged the starter to no avail. During the forced landing, the empennage struck a barbed wire fence short of the runway, and the airplane came to a stop upright. The airplane sustained substantial damage to the empennage and horizontal stabilizer. The pilot reported there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The post-accident examination revealed that the right-wing fuel tank was empty, and the left-wing fuel tank contained seven gallons of fuel.
