On August 3, 1995, at 1600 central daylight time, a Piper PA-23- 250, N76SR, collided with a fence during a forced landing near Monroe, Louisiana. The commercial pilot was not injured and the airplane sustained substantial damage. The airplane was being operated by McMahan Aviation, Inc., of Monroe, Louisiana, under Title 14 CFR Part 91. The personal cross country flight was on an IFR flight plan with visual meteorological conditions prevailing throughout the area. On the enclosed Pilot/Operator Report, the pilot reported that the flight was cleared to descend from 7,000 feet MSL to 3,000 feet MSL for an approach to Monroe, Louisiana. During the descent, the fuel tanks were "switched from outboard to inboard"; however, the pilot "did not confirm they were in the inboard position" and the "lever possibly was in the center position" which is "OFF." Upon reaching 3,000 feet MSL, the right engine "began to surge" and then "quit." The pilot attempted to restart the engine; however, it would not restart, and the pilot stated that he elected not to feaather the propeller. A forced landing to a golf course was initiated. During the landing flare/touchdown, the nose gear struck a metal fence. The left wing struck a tree during the landing roll and the airplane came to rest on the golf course. The Federal Aviation Administration (FAA) inspector examined the airplane and found the fuel selectors on the outboard tanks. The pilot stated that following the accident, he returned to the airplane and moved the fuel selectors to the outboard tanks. The outboard tanks did not contain fuel and the inboard tanks were full. Neither propeller was feathered and the left propeller exhibited torsional twisting. Structural damage occurred to the fuselage, nose gear, left main gear, and the left wing.
